A solar tracker system

Abstract

A solar tracker system is disclosed that enables precise orientation of solar panels in response to environmental forces. The system comprises a solar panel support member and a rotatable mounting means that permits the panel to pivot about a horizontal axis under wind influence. A rotatable support member, in conjunction with a rotary motion conversion mechanism, facilitates controlled rotation, while a wire transmits motor-generated motion to adjust the panel's position. A motion transmission system—including an extension mechanism and a release mechanism—is incorporated to manage force distribution and protect components from damage. In various embodiments, the system further includes dual motor configurations, multiple wiring options with differing materials and elastic properties, computing units for processing weather data and controlling panel orientation, as well as biasing, stop, and dampening structures to ensure optimal and safe operation under varying wind conditions.

Description

[0001] A SOLAR TRACKER SYSTEM

[0002] TECHNICAL FIELD

[0003] The embodiments herein relate to solar energy capturing systems, such as solar panels, solar panel arrays, mounting systems for solar panels, and the like. In particular, embodiments of a solar panel mounting system able to respond, evade or otherwise accommodate external force such as wind, are disclosed.

[0004] BACKGROUND

[0005] Solar energy capturing systems are used to convert light energy to electricity. The conversion of light to electricity is performed by a solar cell, aka photovoltaic cell. The solar cell can be a crystalline silicon cell, athin-fdm cell or the like.

[0006] US16413352 discloses a photovoltaic (PV) module or an array of PV modules which are pivotally mounted from an upper edge and thus designed to hang under the force of gravity and to swing about the upper edge responsive to wind.

[0007] US9494343B2 discloses a partially non-rigid solar capture mounting system which reduces the risk of damage due to wind. The solar capture mounting system includes at least one pole, a horizontal beam mounted to the pole, and at least one backing plate hanging from the horizontal beam via a pivotal connection. Examples of pivotal connection are bushings with ball bearings, hinges, steel rings and spring clips. Each of the backing plates supports at least one solar cell. Wind pressure against a backing plate pivots the backing plate about the horizontal beam such that the system experiences reduced stress and reduced risk of damage due to wind and wind carried objects.

[0008] CN107863922 discloses a suspension-type flexible photovoltaic mounting system in which a framework is provided with flexible cables supporting solar panels. Between the ropes and the panels, triangular rigid bracing elements are attached to improve overall stiffness and reduce out-of-plane deformation. The system further includes additional drag-lines arranged both horizontally and longitudinally to increase stability. By adjusting bracing size and rope anchoring points, the solar panels can be set at different angles, with the goal of forming a new suspension system that reduces large-area rigid support requirements and helps mitigate wind loads.

[0009] KR102276938 discloses a cable-supported solar power generation system adapted for agriculture. A pair of spaced frames support multiple rows of cables; each row of solar panels is attached between front and rear support cables. Adjacent rows of panels share a cable, creating an integrated, continuous cable layout. This mitigates wind-induced vibration by letting the panels and cables move together rather than in isolated sections. Further, the panels are spaced laterally, allowing farmland underneath to receive sunlight. An optional zigzag vertical layout for the cables helps reduce lateral displacement in high winds, improving stability and reducing noise or flutter.

[0010] CN 106712678 discloses a flexible adjustable photovoltaic rope frame structure for mounting solar modules (photovoltaic panels) on flexible cables rather than purely rigid supports. Multiple support members (posts) anchor the cables, and at least two mechanisms at each end permit rotation of the cables about a pivot.

[0011] KR101521810 discloses a solar panel suspension system that employs a tensile and compression structure. A pair of support cables is stretched between two facing support frames, and a solar panel (or multiple panels) is attached to these cables via adjustable clips or bracket plates.

[0012] US 11165384 discloses a system where photovoltaic (PV) modules are allowed to swing or sway in the wind rather than being held rigidly. By hanging PV modules — especially bifacial modules — vertically from a rod or cable, the modules can rotate or pivot about a horizontal axis in response to wind, thereby reducing mechanical stress compared to fixed-tilt panels.

[0013] US20100077592 discloses a system and method for deploying solar panels by suspending them from a substantially horizontal support — such as a tension cable — and allowing them to swing in a pendulumlike fashion. A hinge (or pivot) couples each solar panel to the horizontal support, permitting free rotation in response to wind.

[0014] US20200400772 discloses systems and methods for mechanically limiting or releasing torsional forces (torque) in wind-exposed mechanical systems, particularly in solar tracking assemblies. By placing a torsion limiter (e.g., a torque-limiting slip clutch, a linear slip force limiter, or a hydraulic pressurerelief valve) in the drive system, the tracked array can relieve excessive hinge-moment forces caused by strong winds or obstructions (e.g., snow drifts).

[0015] KR20220157540 discloses a solar panel (photovoltaic) mounting structure designed to reduce wind loads on vertically oriented or near-vertical solar modules. The structure includes a single vertical post anchored in the ground, at least two parallel horizontal crossbars (on that post), and a vertical pivot shaft with bracket(s) that hold solar modules. Each module can pivot about the vertical shaft if subjected to wind pressure, reducing wind stress.

[0016] There exists a need for flexible solar panel mounting systems offering wind responsiveness without imposing prohibitive structural demands and mechanical linkages, in particular there exists a need to provide solar panel mounting systems which can operate efficiently in the presence of wind, or other external forces, while maintaining flexibility of design, ease of installation, and scaleability at reasonable cost.

[0056] In another embodiment, the wheel is configured with multiple anchor points around its circumference, each anchor point adapted to secure an end of the wire or to adjust loop length.

[0057] In another embodiment, a second motor is connected to a second loop of wire around the same wheel.

[0107] In another embodiment, the wheel is adapted so the wire enters at one anchor point and exits at another, enabling fractional loops.

[0108] In another embodiment, two wires form opposite loops around the same wheel, each loop engaging different anchor points.

[0109] In another embodiment, the biasing structure re-engages with the motor once wind force on the panel is below the external force threshold.

[0110] In another embodiment, the motor includes a coupler that drives a biasing structure connected to the panel, shaping its orientation.

[0112] In another embodiment, multiple vertical support members are provided, each with a wheel and wire loop, such that the motor drives the loops for two or more panels at once. In another embodiment, two separate wire loops engage the wheel at different anchor points so that one loop’s movement can oppose tension in the other loop.

[0113] In another embodiment, at least part of the wire is slightly elastic to accommodate tension from wind or motor-driven rotation.

[0114] In another embodiment, that wire is arranged with some segments slightly elastic and some nonelastic, so elasticity is only in predetermined portions.

[0116] In one embodiment, there is provided a solar panel mounting system for at least one solar panel, including a support structure arranged to hold the solar panel such that it may rotate about a rotation axis in response to wind, and a biasing structure configured to influence the orientation of the solar panel about that rotation axis.

[0120] In another embodiment, the support structure is arranged to hold the solar panel in a resting position.

[0121] In another embodiment, the solar panel can rotate away from that resting position when wind is present, and the biasing structure compels it to return once the wind subsides.

[0135] In another embodiment, there is provided a motor, operably coupled to the rotatable vertical member, that can rotate the solar panel about the rotation axis but is configured to disengage at higher wind forces so the biasing structure alone determines the panel’s orientation.

[0136] In another embodiment, the solar panel is permitted to rotate in one direction around the axis to align with wind but is prevented from rotating in the opposite direction, ensuring it can return to the resting position thereafter.

[0137] In another embodiment, an adjustable wire is provided so the resting position of the solar panel can be changed for different operating conditions.

[0138] In another embodiment, a weight rests on the ground at the end of a lever or cable, letting strong wind lift it for extra rotation and allowing gravity to bring the panel back to rest when wind diminishes.

[0139] In another embodiment, the support structure includes a protrusion and at least one spring arranged to block the panel from rotating past a certain angle.

[0140] In another embodiment, once wind surpasses an external threshold, that protrusion and spring let the panel rotate beyond the predefined angle.

[0144] In another embodiment, a rotatable vertical member is provided to define the rotation axis.

[0145] In another embodiment, the horizontal member is connected to the rotatable vertical member, so turning the vertical member also turns the horizontal member and the solar panel.

[0146] In another embodiment, the support structure is arranged so the solar panel can be held in a resting position.

[0147] In another embodiment, the method involves permitting the solar panel to rotate away from that resting position if wind is present, and having the biasing structure return it to rest once the wind subsides.

[0148] In another embodiment, providing the biasing structure includes providing a shaft in an aperture with profiles arranged so the panel returns to the resting position.

[0149] In another embodiment, providing the biasing structure involves arranging a spring that lets the solar panel move under wind but orients it once wind decreases.

[0150] In another embodiment, the rotation axis is located off-center relative to the solar panel.

[0151] In another embodiment, providing the biasing structure includes providing a weight that helps rotate the solar panel.

[0152] In another embodiment, the biasing structure is adapted to bias the panel within a certain interval while applying little or no bias beyond that interval.

[0153] In another embodiment, the weight is positioned at about 90 to 130 degrees relative to the solar panel.

[0154] In another embodiment, a tension spring is supplied so it flexes under wind-induced movement and unflexes afterward.

[0155] In another embodiment, a release mechanism can decouple the biasing structure if wind surpasses an external force threshold. In another embodiment, once wind is below that threshold, the release mechanism re-engages the biasing structure to restore the panel to rest.

[0156] In another embodiment, a shaped stop is provided to physically limit how far the panel can rotate.

[0157] In another embodiment, the panel is allowed to move toward that shaped stop partly via gravity.

[0158] In another embodiment, both a spring and a weight are included in the biasing structure.

[0159] In another embodiment, at least one magnet is arranged to hold the panel at rest until wind exceeds an external threshold.

[0160] In another embodiment, once the wind is below that threshold, the magnet re-engages to keep the panel in resting position.

[0161] In another embodiment, the method further includes operably coupling a motor to rotate the panel around the axis, and configuring the motor to disengage if wind forces surpass a certain level, so the biasing structure alone repositions the panel to rest.

[0162] In another embodiment, the method permits the panel to rotate one way around the axis to align with wind, while blocking an opposite rotation so it can return to rest.

[0163] In another embodiment, an adjustable wire is provided so the resting position of the panel can be shifted for different conditions.

[0164] In another embodiment, a weight on the ground at the end of a lever or cable is adapted to be lifted by strong wind for extra rotation, with gravity drawing the panel back once wind eases.

[0165] In another embodiment, at least one protrusion and spring are arranged to block rotation of the panel past a predefined angle.

[0166] In another embodiment, if wind force exceeds an external threshold, the panel is permitted to rotate beyond that angle through cooperation of the protrusion and spring.

[0167] In another embodiment, a bar is connected to the support structure so the panel rests on it at the resting position.

[0168] In another embodiment, a stop bar extends from the rotatable vertical member, enabling the panel to locate itself at a resting position.

[0169] In one embodiment, a rotary motion conversion mechanism for controlling rotation of a support member in a solar panel mounting system comprises a body defining a central opening configured to be secured around or attached to the support member; a circumferential portion of the body including one or more annular channels extending at least partially around the mechanism for receiving at least one wire; a plurality of anchor points spaced around the circumferential portion, each anchor point adapted to selectively secure an end of the wire; and one or more locking members positioned adjacent to at least one anchor point and configured to retain the wire under tension within the corresponding channel, wherein tension in the wire, when wrapped at least partially around the circumferential portion, transmits rotational force to the rotary motion conversion mechanism, thereby causing the support member to rotate.

[0170] In another embodiment, an adjustable clamp mechanism is coupled to the body, the clamp mechanism configured to enable the rotary motion conversion mechanism to be repositioned along a length of the support member.

[0171] In another embodiment, a motion transmission extension mechanism is arranged along the wire, the mechanism being configured to partially relieve tension exerted by wind forces on a solar panel coupled to the support member.

[0172] In another embodiment, the motion transmission extension mechanism is a spring assembly that extends or compresses in response to loads on the wire, thereby smoothing abrupt rotational shifts of the support member in windy conditions.

[0173] In another embodiment, a release mechanism is disposed in or along the wire, the release mechanism being adapted to disengage the wire from the circumferential portion when a predetermined torque threshold is exceeded.

[0174] In another embodiment, two or more separate wires are each looped around respective annular channels, enabling independent or coordinated rotation of multiple solar panel supports attached to a single motor or drive mechanism.

[0175] In another embodiment, at least one textured or high-friction surface is provided in the annular channel to reduce the risk of wire slippage when tension is applied by a motor or by wind-induced torque on the support member.

[0176] In another embodiment, the one or more annular channels are dimensioned to permit partial loops of the wire, allowing rotation in excess of 360 degrees around the support member.

[0177] In another embodiment, angular anchor points arranged around the circumferential portion enable the wire to be locked at a different rotational offset relative to the support member.

[0178] In another embodiment, the anchor points are spaced between 40 degrees and 120 degrees apart around the circumferential portion of the rotary motion conversion mechanism.

[0179] In another embodiment, the wire includes a weakened or breakable loop configured to fail at a specified tension, thereby acting as a sacrificial element to protect the rotary motion conversion mechanism from excessive loads.

In another embodiment, the method further comprises configuring the blocking structure to primarily restrict rotation in one direction around the rotation axis while permitting rotation in the opposite direction.

[0356] In another embodiment, the method further comprises providing a weight that biases the solar panel toward a preferred angle under mild wind conditions in cooperation with the blocking structure.

[0363] In another embodiment, the method further comprises providing the blocking structure with a hinged pivot that allows it to swing away under a load above a predetermined threshold, thereby freeing the panel for additional rotation.

[0364] In another embodiment, the method further comprises incorporating a sensor or computing device configured to measure wind speed or direction and to trigger the release structure if wind conditions exceed a preset threshold.

[0379] In another embodiment, the method further comprises providing a dampening member arranged between the solar panel support member and the solar panel, adapted to cushion impact when the panel swings into the support member under wind-driven rotation.

[0380] In another embodiment, the method further comprises configuring the motor to disengage at wind speeds above an external force threshold, thereby allowing wind-induced rotation of the solar panel up to the point constrained by the blocking structure.

[0381] Accordingly, there is provided a solar panel suspension system for suspending wind-responsive solar panels above ground, thereby making the ground available. However, in some examples, it may be that the ground is not available. The solar panel suspension system comprises two suspension structures directly or indirectly connected to the ground and located at a distance from the ground. Each of the two suspension structures can be a respective distal end of a respective beam, e.g. being substantially vertical. The solar panel suspension system further comprises an elongated arrangement, e.g. at least one elongated arrangement. The elongated arrangement comprises the wind-responsive solar panels. The elongated arrangement is suspended and extends between the two suspension structures. Moreover, the solar panel suspension system comprises an elongated support, such as a wire, a bar, a stick, a beam, or the like, suspended and extending between the two suspension structures. The elongated support is arranged, and e.g. located, or the like, to directly or indirectly hold, or abut, at a distal portion of the elongated arrangement, the wind-responsive solar panels, at an angle, e.g. relatively a vertical plane XY. Then, elongated support is arranged to hold the elongated arrangement, or the solar panel, at the angle, when the wind-responsive solar panels (400) are subjected to wind above a threshold value, or e.g. subjected to wind in an interval.

[0382] In some embodiments, the aforementioned realization of the wind-responsive solar panel suspension system can be employed for the purpose of improving the system’s ability to remain intact when exposed to strong winds. The systems herein can, also or alternatively, reduce the solar panels’ fluttering and / or oscillation, which can occur when the panels are subjected to wind. Thanks to that the wind-responsive solar panel merely leans on, or abuts, the elongated support, it is possible for the wind-responsive solar panels to initially hang vertically, i.e. in no wind or little wind conditions, and then, e.g. when exposed to sufficiently strong winds, be rotated until the distal portion of the elongated arrangement, or the distal portion of the solar panel, abuts against the elongated support. In this manner, the elongated support can hold the solar panel steadily at an angle, i.e. the same angle, as long as the wind is above a threshold value.

[0383] In some embodiments, the wind-responsive solar panels can be arranged to have an angle of rotation, e.g. with respect to a vertical plane, that is non-zero as an initial position. This can e.g. be achieved by a counterweight, or the like. In some examples, the counterweight can be mounted at the end of a lever arm to bring the solar panel to the non-zero initial position. One end of the lever arm can be connected to the counterweight and the other end of the lever arm can be connected to the solar panel, the lever arm preferably extending transversally away from the elongated arrangement that includes the solar panel. As mentioned before, the initial position can sometimes be zero, which thus corresponds to that the solar panel is aligned with a vertical plane, e.g. parallel with the vertical plane.

[0384] In some embodiments, the elongated support is arranged, e.g. positioned, to hold, directly at the distal portion of the elongated arrangement, or the wind-responsive solar panel, at the angle. This means for example that the wind-responsive solar panel of the elongated arrangement, or a projecting element of the elongated arrangement, leans on the elongated support, e.g. when held at the angle. The projecting element can project from an upper portion of the elongated arrangement towards the ground.

[0385] A position of the elongated support can be adjusted to adjust the angle. This can for example be achieved by that ends of the elongated support are mountable at one of a respective plurality of locations at each one of the two suspension structures. Alternatively or additionally, the angle can be adjusted based on a length of the elongated support, e.g. when realized as a wire, where a longer wire decreases the angle due to parabolic shape of a hanging wire.

[0386] An advantage can also be that the elongated support can be moved not to interact with the elongated arrangement and thus no longer setting the angle of the elongated arrangement. This provides a fast mechanism for activating or de-activating the angle adjustment achieved by the elongated support. In some embodiments, the elongated, flexible member can be a string, a belt, a wire, a rope, a line, a portion of a flexible layer of the wind-responsive solar panel, or the like.

[0387] In some embodiments, the elongated, flexible member is electrically non-conducting.

[0388] The elongated, flexible member can comprise, such as be made of, or the like, a flexible material. The flexible material can be aluminum, a flexible plastic material, fiber glass, or the like.

[0389] In some examples, the solar panel suspension system is a large-scale solar park. The solar panel suspension system can then have multiple elongated arrangements, such as 3, 4, 5 or more as required by the circumstances. Further, each of said multiple elongated arrangements can then be provided with a plurality of wind-responsive solar panels.

[0390] In some embodiments, the first and second elongated arrangements comprises a respective solar cell rod, or “rod” for short, that is provided with the first or second set of wind-responsive solar panels, respectively. The first and second set of wind-responsive solar panels extend, towards the ground, from a respective bottom surface of the respective rod.

[0391] According to one aspect of the present invention, there is provided a solar panel suspension system for suspending wind-responsive solar panels. The system comprises two suspension points, e.g. at a suspension structure, and an elongated arrangement that is suspended and extends between the two suspension points. The elongated arrangement comprises the wind-responsive solar panels. The elongated arrangement is arranged to permit rotation of the wind-responsive solar panels about a rotation axis running along a main extension direction of the elongated arrangement. The system further comprises a blocking structure arranged to, e.g. only, apply its limitation of the rotation of the wind-responsive solar panels outside a rotation interval, and preferably not apply its limitation of the rotation within the rotation interval.

[0392] Expressed differently, the blocking structure can be arranged to constrain the rotation of the wind- responsive solar panels, e.g. only, outside the rotation interval, e.g. where the blocking structure applies, e.g. activates, limitation of the rotational motion of the wind-responsive solar panels.

[0393] The blocking structure can be arranged to, e.g. only, apply its limitation of the rotation of the wind- responsive solar panels outside the rotation interval. The blocking structure can be arranged to apply the limitation of the rotation outside the rotation interval. The blocking structure can be arranged to only apply the limitation outside the rotation interval. The blocking structure can be arranged to be freely rotatable within the rotation interval, e.g. freely rotatable in terms of that the limitation of the rotation by the blocking structure is not applied within the interval. Expressed differently, The blocking structure can be arranged to refrain from applying its limitation of the rotation within the rotation interval. The rotation interval can have a start angle, defining one end point of the interval, and a stop angle, defining the other end point of the interval. A reference point, at which the angle is zero, can be set at any one of the end point, or for example at a center point of the interval. The center point can then be zero, e.g. when the solar panel hangs vertically. Thus, in one example, the interval be range from -90 to 90, -85 to 85, or the like. The interval thus pertains to when the blocking structure applies no limitation, or substantially no limitation, to the rotation of the solar panel.

[0394] In some examples, it can be that the blocking structure’s limitation of the rotation interval is applied when the blocking structure begins to abut the solar panel.

[0395] Thanks to the blocking structure fluttering and / or oscillation of the elongated arrangement, including e.g. the wind-responsive solar panel(s), can be reduced, or even eliminated. This effect can be accentuated when the wind that the system is subjected to is above a threshold value, such as 10 m / s, 15 m / s, 20 m / s, or the like. According to the embodiments herein, there is thus provided a blocking structure for limiting rotation of the wind-responsive solar panels.

[0396] A purpose of at least some embodiments herein is to reduce fluttering of the wind-responsive solar panels. This can be achieved by limiting the angle of rotation of the wind-responsive solar panels. For example, the rotation can be limited when the angle of rotation exceeds e.g. 90 degrees, 85 degrees, 80 degrees, 75 degrees, 70 degrees, or the like.

[0397] In some embodiments, the rotation interval is defined by that, at an end point thereof, a distal portion of the elongated arrangement abuts the blocking structure and / or that the blocking structure is arranged to begin application of the limitation of the rotation at an / the end point of the rotation interval. As an example, the blocking structure can be arranged to, at the end point(s) of the rotation interval to successively limit the rotation. This means for example that once a distal portion of the elongated arrangement abuts the blocking structure, the rotation of the solar panel may be stopped directly or may not be stopped directly. The rotation may not be directly stopped, e.g. when the blocking structure’s position can be disturbed by the wind and / or by the solar panel, e.g. when the wind is sufficiently strong.

[0398] In some embodiments, the blocking structure is elongated. The blocking structure is arranged along the elongated arrangement. In these embodiments, the blocking structure can comprise the elongated support. The blocking structure can be suspended between two further suspension points, e.g. at the suspension structure. The two further suspension point can be located at a distance below the initially mentioned suspension point.

[0399] In some embodiments, the blocking structure is elongated. The blocking structure is arranged transversally to the elongated arrangement. The elongated arrangement comprises a longitudinal protrusion that is arranged to abut the blocking structure when the elongated arrangement is forced to the end(s) of the rotation interval. The longitudinal protrusion can extend beyond at least one solar panel in a longitudinal direction of the elongated arrangement. The blocking structure can be suspended between two additional suspension points, e.g. at the suspension structure.

[0400] In some embodiments, the blocking structure can cooperate, such as abut against, or the like, the wind- responsive solar panel, such as the periphery thereof, a frame thereof, a distal portion thereof, or the like. In these embodiments, the blocking structure is separate from the elongated arrangement, but in some examples the blocking structure can include a further part that is integrated with the elongated arrangement, while the blocking structure, not including the further part, is separated from the elongated arrangement as already mentioned.

[0401] In some embodiments, the system comprises a further blocking structure arranged to abut against a central portion of the elongated arrangement, when the elongated arrangement is forced to an / the end of the rotation interval. Advantageously, the elongated arrangement can have a length, e.g. in the main extension direction of the elongated arrangement that is e.g. in a range of 1 to 10 meters, 1 to 5 meters, 1 to 3 meters, or the like.

[0402] In some embodiments, the system comprises an additional blocking structure. The additional blocking structure is elongated. The additional blocking structure is arranged transversally to the elongated arrangement. The elongated arrangement comprises an additional longitudinal protrusion that is arranged to abut the additional blocking structure when the elongated arrangement is forced to the end(s) of the rotation interval.

[0403] In some embodiments, the additional blocking structure is located closer to the solar panel than the blocking structure as seen in a longitudinal direction. The additional longitudinal protrusion can extend beyond at least one solar panel in a longitudinal direction of the elongated arrangement. In this manner, bending, or flexing, of the solar panel can be reduced, or even avoided. In this context, it is bending refers to bending of the solar panel about a geometric axis running parallelly to the main extension direction of the elongated arrangement, but at a distance from the main extension direction.

[0404] In some embodiments, the elongated arrangement comprises the blocking structure that comprises a distal, lateral protrusion extending transversally a main extension plane of the solar panels. The distal, lateral protrusion is arranged to abut an elongated suspension structure when the elongated arrangement is forced to the end of the rotation interval.

[0405] In some embodiments, a distal portion of the solar panel is configured to allow longitudinal distal ends of the distal portion to be offset in relation to a central portion of the distal portion. The central portion is arranged to be offset relatively a geometric line through the longitudinal distal ends of the distal portion, when the solar panel is subjected to wind and the end of the rotation interval is reached. The distal portion can be flexible or include rigid sections as exemplified below. In some embodiments, the distal portion is flexible. The distal portion can include a bar, a rod, or the like. The distal portion can be made of a flexible material that e.g. allows the distal portion to bend, e.g. when subjected to wind, e.g. above a threshold value.

[0406] In some embodiments, at least one of, preferably both, the longitudinal distal ends of the distal portion is provided with an engagement element, such as a hook, a clasp, a latch, a spike , a buckle, a fastener, a snap, a button, a loop, a magnet, a catch, a toggle, a pin, a rivet, or the like, whereby a risk of that the elongated arrangement breaks free from the blocking structure, when the distal portion flexes, is reduced.

[0407] In some embodiments, the distal portion comprises one or more stiff sections, e.g. being flexibly connected to each other, e.g. with at flexible material, a joint, or the like.

[0408] In some embodiments, the blocking structure is stiff and / or rigid. The blocking structure is located at a distal end of the beam. The blocking structure comprises a first portion and a second portion. The blocking structure is arranged to allow the distal portion of the solar panel to abut the first or second portion when the elongated arrangement is forced, e.g. by wind, to the respective end of the rotation interval.

[0409] In some embodiments, the blocking structure comprises a flexible elongated member, such as a line, or the like, that is connected to the distal portion of the elongated arrangement and to a fixed point located below, at least along the vertical direction, the distal portion’s location when not subjected to wind.

[0410] In some embodiments, e.g. when the blocking structure is elongated, the blocking structure can be a flexible elongated member, such as a wire, a line, a rope, or the like.

[0411] In some embodiments, the fixed point is located at the suspension structure, such as a beam, or the like. As an example, the fixed point is located at a lower part of the suspension structure, e.g. as above below the distal portion’s location, i.e. when positioned at the predefined angle.

[0412] In some embodiments, the fixed point is located on the ground in the vicinity of, or in, an area beneath the solar panels.

[0413] In some embodiments, the blocking structure comprises a shock absorbing material at least at portions of the blocking structure that are arranged to abut the elongated arrangement when located outside the rotation interval. Examples of a shock absorbing material include rubber, foam, gel, silicone, elastomer, neoprene, polyurethane, or the like.

[0414] The expression “a blocking structure arranged to apply its limitation of the rotation of the wind- responsive solar panels outside a rotation interval”, and variations thereof according to the embodiments herein, can be understood as comprising two parts: 1) the embodiment relating to the elongated support, as an example of the blocking structure, and 2) embodiments relating to the blocking structure, other than the embodiment relating to the elongated support.

[0415] In view of the systems where the solar panels are suspended in a manner such that the solar panels are movable in response to wind, a problem with the aforementioned known solar panel can be related to its heavy weight or the like. As described above, flexible solar panel can be a good choice when seeking light-weight solar panels, but at the expense of cost.

[0416] According to another aspect, there is provided a solar panel suspension system for suspending wind- responsive solar panels. The system comprises two suspension points, an elongated arrangement that is suspended and extends between the two suspension points. The elongated arrangement comprises the wind-responsive solar panels. The elongated arrangement is arranged to permit rotation of the wind- responsive solar panels about a rotation axis running along a main extension direction of the elongated arrangement, and a biasing structure arranged to bias the wind-responsive solar panel towards a predefined rotation angle. The biasing structure is arranged to apply its biasing of the wind-responsive solar panels towards the predefined rotation angle within a bias interval. Furthermore, the biasing structure is arranged to apply no or less of its biasing of the wind-responsive solar panels towards the predefined rotation angle outside the bias interval.

[0417] Thanks to that the biasing structure is arranged to apply its biasing of the wind-responsive solar panels towards the predefined rotation angle within the bias interval, and to apply no or less biasing of the wind-responsive solar panels towards the predefined rotation angle outside the bias interval, the predefined angle can be held, e.g. steadily by the system, even when subjected to light wind, e.g. up to a threshold value. The threshold value can be in a range of 1-6 m / s, 2-5 m / s, 2-4 m / s, or the like.

[0418] In some embodiments, the biasing structure is arranged to allow the wind-responsive solar panels to rotate freely with respect to biasing applied by the biasing structure outside the bias interval. Outside the bias interval, the wind-responsive solar panels’ rotation can though be limited by other factors than the biasing structure. For example, the blocking structure, biasing originating from gravity, or the like.

[0419] In some embodiments, the wind-responsive solar panel is freely rotatable in at least a free rotation interval outside the bias interval. In more detail, there can be a first free rotation interval and a second free rotation interval, symmetrically located at opposite sides of the bias interval. The free rotation interval can have a length in a range of 0 degrees to 40, 50, 60, 70 degrees and start at 5, 10 degrees relatively the predefined angle. The free rotation interval is non-overlapping with the bias interval. It can here be noted that the free rotation interval is not the same as the rotation interval. In the free rotation interval, the biasing structure does not prevent, such as reduce, brake, mitigate, or the like, but the rotation is of course subjected to general resistance, such as friction, gravity, air resistance, or other practical and naturally occurring phenomena. In some embodiments, the biasing structure comprises a suspension part and a solar panel part. The suspension part can be stationary in terms of that the part is not rotatable about to the rotation axis of the solar panel part, or in a plane perpendicular to the rotation axis. The solar panel part can be rotatable. The suspension part can be arranged to be fixedly connected to at least one of the two suspension points. The solar panel part can be arranged to be fixedly connected to the solar panel(s), which is the reason for the notation “solar panel part”. Clearly, the solar panel part does not have to be integrated with the solar panel, but as the solar panel rotates the solar panel part will also rotate. Thus, the suspension part can be referred to as “stationary part” and / or the solar panel part can be referred to as “rotatable part”.

[0420] In some embodiments, the suspension part comprises a shaft and the solar panel part comprises a holding element. These embodiments can be referred to as inverted embodiments or examples. Alternatively, in some embodiments, the suspension part comprises the holding element and the solar panel part comprises the shaft. These embodiments can be referred to as non-inverted embodiments or examples.

[0421] In some embodiments, the suspension part and the solar panel part can jointly form a hinge assembly allowing the elongated arrangement 600 to be rotatable about the rotation axis, e.g. extending along the main extension direction of the elongated arrangement.

[0422] The holding element is thus configured to receive the shaft, e.g. by receiving the shaft in an aperture of the holding element. The holding element can be a portion of a beam at which one of the two suspension points is located. This implies that there can be a first holding element and a second holding element, e.g. one at a respective end of the elongated arrangement.

[0423] The shaft and the holding element can be configured to cooperatively apply the biasing structure’s biasing of the wind-responsive solar panels towards the predefined rotation angle within the bias interval, and to apply no or less biasing of the wind-responsive solar panels (400) towards the predefined rotation angle outside the bias interval. The shaft and the holding element can implement the biasing, provided by the biasing structure, by one or more of: i) configuration of their respective shapes, ii) magnetism, iii) mechanical spring biasing. The configuration of shapes refers to that at least some overlapping cross-sections of the shaft and the holding element are configured to cooperate to achieve the bias. Biasing by magnetism refers to that one of the shaft and the holding element can be provided with a magnet and the other one of the shaft and the holding element can be provided with a magnetic material, thereby magnetism can subject the shaft and the holding element to attracting forces, which e.g. are insignificant outside the bias interval, e.g. the attracting forces are not dominating, as compared to other practically and naturally occurring phenomena, outside the bias interval. By combining a mechanical spring bias and the configuration of shapes, it can be achieved that the biasing structure is arranged to apply its biasing of the wind-responsive solar panels towards the predefined rotation angle within the bias interval, and to apply no or less biasing of the wind- responsive solar panels (400) towards the predefined rotation angle outside the bias interval. A mechanical spring bias without combination with configuration of the shapes will proportionally apply a greater and greater bias the further away from an equilibrium the solar panels are moved. Hence, with such mechanical spring bias, it is impossible to rotate the solar panels outside the spring bias’s bias interval.

[0424] According to some inverted embodiments, the shaft is fixedly connected and suspended between the two suspension points and the aperture is provided in the holding element fixedly connected to the solar panels.

[0425] According to some non-inverted embodiments, the shaft is fixedly connected to the solar panels and the holding element is fixedly connected and suspended at one of the suspension points. At the other suspension point, there is typically a further holding element. The holding element is provided with the aperture configured to receive the shaft.

[0669] DETAILED DESCRIPTION

[0670] The present disclosure relates to comprehensive solar panel mounting systems designed to address multiple challenges associated with operating solar panels under varying environmental conditions, especially in the presence of wind. Traditional solar panel trackers often contend with high wind forces, risk of oscillation or galloping, motor-overload issues, and difficulties in repositioning panels during storms or snow loads.

[0671] A variety of aspects and embodiments are presented herein, each directed to mechanical and / or control features that allow the solar panels to rotate or pivot — whether in response to wind-induced loading, motor-driven actuation, or a combination thereof, both along horizontal or vertical axis.

[0672] The present disclosure contains many examples, embodiments or aspects of the present invention, so as to fully describe solar panel mounting systems and the like according to the present invention. To aid in interpretation and understanding, reference numerals will be linked to example Figures to which they relate. For example reference numeral ”75-105” would refer to component 105 which may be viewed, at the least, in Figure 75.

[0673] In certain embodiments, the solar panel mounting system includes rotatable vertical support members that permit bulk reorientation of solar panels about a vertical axis. Some implementations further feature horizontal support members to which individual panels are pivotably attached, enabling passive rotation when wind loads exceed a threshold. Other embodiments incorporate biasing structures (e.g., springs, wedges, or counterweights) designed to hold panels at a resting orientation under moderate conditions, yet allow additional rotation or decoupling upon encountering stronger winds or gusts.

[0674] Across the specification, distinct aspects of the invention focus on different but complementary features:

[0675] Motorized Rotation: One or more motors and coupling mechanisms (including tensioned wires, wheels, or gear assemblies) for actively adjusting the panel orientation, as determined by environmental inputs.

[0676] Wind-Responsive Elements: Movement of the solar panels resulting from wind force, aided or limited by stop members, dampening assemblies, or release mechanisms that prevent harmful over-rotation.

[0677] Computational Control: A computing unit that may detect and interpret environmental data, such as wind speed / direction or sun position, and then automatically command the system’s motor(s) or release certain mechanical linkages to protect the panels.

[0678] Mechanical Biasing & Blocking: Various solutions (springs, wedges, rails, stops) that urge panels toward a safe or optimal default orientation, while still accommodating some rotation above a predetermined force threshold.

[0679] Although certain embodiments are presented individually, it will be appreciated that features disclosed in one section — such as locking members for wire-based rotation, hinged through-holes for cable routing, or wedge receiving members — may be combined or substituted with features from other embodiments in accordance with the principles and objectives detailed herein. Accordingly, while the central inventive concept is a solar panel mounting system robust to wind loads, the ensuing detailed descriptions and claims encompass multiple configurations and subassemblies that realize this concept in various environments. Unless otherwise indicated as mutually exclusive, these disclosed aspects and embodiments can be readily integrated or adapted by persons skilled in the art to achieve wind accommodation, motorized orientation, and biasing functionalities for solar panel installations of diverse scales.

[0680] The combined systems described herein utilize biasing mechanisms and strategies to direct or otherwise encourage solar panels to predetermined positions. These strategies may include, for instance, counterweights, magnetic biasing, springs or dampeners, stop bars, stop wires, and decoupling mechanisms that permit panels to rotate or pivot — sometimes fully freely, sometimes with a pre-set threshold — depending on the magnitude and direction of wind or other external forces.

[0681] Additionally, certain embodiments enable actively driving the panels (e.g., with a high-torque motor) to face the sun in calm conditions, while also allowing them to pivot out of harm’s way or reduce torque demands when wind exceeds a given threshold.

[0682] As used herein, the terms “include” and “comprise” are used interchangeably and are intended to have the same meaning (i.e. that additional features, such as elements, parts, items, or the like, can also be present even if not explicitly mentioned). The terms “comprise” and “include” are thus open-ended.

[0683] As used herein, the expression “fixedly connected” refers to two or more components being securely joined or attached together in a manner that prevents movement, rotation, or separation under normal operating conditions. This implies a permanent or semi-permanent connection that is not easily disassembled without the use of tools or deliberate effort (which can include permanent or temporary destruction of the components and / or their fixed connection). This expression indicates a stable and durable relationship between the components.

[0684] The present disclosure is structured to provide multiple embodiments of the present invention, all incorporating elements of the aforementioned biasing mechanisms and strategies.

[0685] Throughout the present disclosure, the following terms and definition may be used.

[0686] As used herein, a solar cell, aka a photovoltaic cell, is capable of generating electricity when illuminated by light. Solar cells are commonly available on the market, such as crystalline solar cells, mono crystalline solar cells, poly crystalline solar cells, thin-film solar cells, or the like.

[0687] As used herein, the terms wire, rope, conducting or non-conducting line, string, band, belt may have been used interchangeably.

[0688] As used herein, the term “solar panel” refers to a panel comprising one or more photovoltaic cells, aka solar cells. As used herein, the term “solar panel suspension system” and the like may be interchangeably used with terms such as “solar panel mounting system”, “solar panel system” and the like. These terms are intended to refer to the same form of structure, a system for mounting or otherwise supporting one or more solar panels.

[0689] Certain embodiments of the present invention will now be described with reference to Figures 1 to 64, which demonstrate systems solar where panels can rotate around an axis, utilizing certain mechanical elements or shaping of the panel and support structures to bias the panel toward a preferred rest angle.

[0690] As used herein, the terms “first direction”, “second direction” and “third direction” have been used to refer to an x-axis, e.g. width, a y-axis, e.g. height, and a z-axis, e.g. depth, of a first coordinate system aligned with the exemplifying solar panel suspension systems disclosed herein. Similarly, a first plane refers to the xy-plane (XY) of the first coordinate system, a second plane refers to the yz-plane (YZ) of the first coordinate system and a third plane refers to the xz-plane (XZ) of the first coordinate system. For ease of understanding, it is herein described as that the coordinate system related to various examples illustrated in the Figures are aligned, but it is evident that when considering e.g. only the solar panel, the planes and directions of the solar panel are independent of other coordinate systems, such as directions and planes of the first coordinate system. A few examples include, but are not limited to, that the first plane (XY) can be a main extension plane of the solar panel and / or the elongated arrangement including solar panels, the first direction (X) can be a main elongation direction of the elongated arrangement, the second direction (Y) can be a main elongation direction of a beam, e.g. a vertical beam, the third direction (Z) can be a main elongation direction of an elongated suspension structure, and the like.

[0691] The term ’’solar panel” refers to any form of commercially available solar panel designed to absorb sunlight and convert it into electricity. It typically consists of an assembly of interconnected solar cells, which are semiconductor devices made most commonly from silicon. These cells capture photons from sunlight and release electrons, thereby generating an electrical current.

[0692] As used herein, various reference may be made to “solar panel structure”, “solar panel array”, “solar panels” and the like. It is intended to be understood that multiple solar panels or the like may form an array or structure or the like, and reference to a single solar panel does not preclude the suitability of the present invention from being used with multiple solar panels, and vice-versa.

[0693] The term “wind-responsive solar panel” refers to a solar panel that is capable of moving in response to wind, e.g. due to a particular design thereof or due to being connected to a particular mounting construction enabling movement in response to wind. Generally, a wind-responsive solar panel can be any sheet or layer provided with solar cells, where the sheet or layer is mounted in such a way that the sheet or layer can rotate in response to wind, e.g. wind that is strong enough to move the sheet or layer. The wind-responsive solar panel can be a flexible solar panel, such as a thin-film solar panel, a lightweight thin and flexible solar panel, a conventional non-flexible panel connected to a mounting construction enabling movement in response to wind, or the like, as described herein. That is to say, in some embodiments a conventional solar panel can be used. The wind-responsive solar panel can be lightweight in order to allow wind to tilt, rotate, bend and / or flex the wind-responsive solar panel. This means that the wind-responsive solar panel can be flexible and / or bendable. However, in some examples it can be sufficient that the wind-responsive solar panel is rotatably mounted and / or mounted with hinges to allow the panel to move when subjected to wind, e.g. sufficiently strong winds. Hence, the wind-responsive solar panel can be arranged to be pivotably and / or rotatably connected, e.g. mechanically connected, to a mounting system, e.g. in a mounting edge of the wind-responsive solar panel. In some examples, solar cells of said one or more respective wind-responsive solar panels can rotate and / or flex, in response to wind, e.g. about one or more rotation axes, which can extend along a main elongated direction (X) of the respective solar cell rod. The wind-responsive solar panel can be electrically connected, e.g. via the mounting edge or directly, to one or more further wind-responsive solar panels.

[0694] It should be understood that any solar panel may be a “wind-responsive solar panel” by virtue of its adoption in a solar panel mounting system according to the present invention.

[0695] The term “elongated arrangement”, or “set of wind-responsive solar panels interconnected, e.g. mechanically and / or electrically, to form an elongated, flexible arrangement”, refers to a set of wind- responsive solar panels that are arranged and aligned along a geometric axis, e.g. in the first direction (X). The elongated arrangement can be realized according to known manners or it can be realized as described according to various embodiments herein.

[0696] As used herein, the term "subjected to wind" refers to that the wind is actively affecting or interacting with e.g. a solar panel in some way, e.g. causing the solar panel to move from one position to another, e.g. holding the solar panel against a blocking structure, or the like. As an example, the wind can be above a threshold value in order to be able to significantly move and / or rotate the solar panel. Furthermore, when the solar panel is subjected to no wind, it can mean that the wind is below a threshold value. Generally, when wind is discussed, wind speed, such as average wind speed, can be intended, in particular in relation to thresholds, such as threshold values, limits, limit values or the like.

[0697] As used herein, “distal” generally refers to a portion of an element that is located away from the element’s connection point or its center point, depending on context. E.g. a distal end of a beam can refer to the end of the beam that is not connected, or to any one of the ends of the beam if the beam is connected in both ends or if the beam is connected at a middle portion thereof. In case a unit is connected to allow rotation about a longitudinal axis, then distal refers to parts of the unit that are at a distance, or furthest away from, or almost furthest away from, the rotation axis. One example of such a unit can be the elongated arrangement.

[0698] As used herein, the terms "solar panel mounting system," "solar panel suspension system," and "solar panel system" may be used to refer to any overall structure, framework, or apparatus designed to hold or support solar panels in place, often incorporating features that enable the panels to respond to environmental conditions such as wind.

[0699] As used herein, the terms "blocking structure", “blocking member”, “blocking mechanism”, ’’stop heel”, "stop bar", "stop wire", "limiting / rotation-limiting structure", ” rotation limiters”, ’’rotationblocking structure”, and "elongated blocking structure" or the like may be used to refer to any element (such as a beam, cable, bar, or rod) that restricts, confines or otherwise limits the range of rotational or pivoting movement of solar panels, typically to prevent excessive movement or to define a desired rotation interval.

[0700] As used herein, the terms “bias”, “biasing”, "biasing structure," ’’biasing member”, “biasing mechanism”, "counterweight mechanism," "spring or dampener arrangement," "magnetic bias," "gravity-based torque or shaping that biases to a rest angle" and the like, may be used to refer to any setup or device that provides a controlled restoring force or torque to a solar panel, a support member holding a solar panel, or any component within a solar panel system, urging or compelling it toward a preferred orientation, location, position or angle (e.g., using springs, magnets, weights, wire, or tailored panel geometry). Biasing may occur within a set bias interval or constantly, depending on implementation and different aspects of the present invention, as would be understood by a person skilled in the art.

[0701] As used herein, the terms "coupler", "cable system", "coupling rod", “wire”, “wire loop”, and "loop of cables" may be used to refer to any linkage or transmission component that connects a drive (such as a motor) to one or more solar panels or panel-support rods, thereby transferring rotational motion or torque.

[0702] As used herein, the terms "motor", "high-torque motor", "motor drive means," and "drive means" may be to refer to any powered device or assembly (e.g., an electric motor) that actively adjusts the orientation of solar panels, typically rotating them around a vertical or horizontal axis to optimize sunlight capture or manage wind loads.

[0703] As used herein, the terms "vertical support member," "beam", "rotatable vertical member”, "pole" "post", ’’support member”, "support beam", and "ground-anchored support" may be used to refer to any upright structural element and serving as a vertical support for solar panels, or other support members, sometimes designed to rotate about its own axis.

[0704] As used herein, the terms "solar panel support member", "mounting frame", "horizontal support member", "upper / lower solar panel support member", "bar", "rod", "beam," and "frame portion" may be used to refer to any elongated or rigid piece designed to hold or attach to the panels laterally, often extending horizontally or diagonally, and sometimes capable of pivoting.

[0705] Various aspects of the present invention describe support members and / or support structures configured to define one or more rotation axes. For example, a vertical support member may establish a vertical rotation axis about which a horizontal support arm and any attached solar panels can pivot. Similarly, a horizontal beam, horizontal support member, or shaft may provide a horizontal rotation axis, permitting the solar panel(s) to tilt, sway or rotate, in response to wind. In some implementations, these structural members are arranged so that their alignment naturally locates the rotation axis, such as by employing hinges, bearings, or pivot joints integrated into the support members. As a result, a single support structure can provide both a primary rotation axis and one or more subsidiary axes, thereby enabling the solar panel(s) to rotate in multiple planes under different environmental forces or user commands.

[0706] Throughout the present disclosure, reference is made to “external force thresholds”, “safety thresholds”, “predetermined thresholds”, “strong wind” and similar. These thresholds indicate points at which specific actions occur with reference to a solar panel mounting system according to the present invention. These thresholds are dynamic in that they may change depending on circumstance or situation, in order to aid in the interpretation and understanding of these thresholds, the following information is provided:

[0707] Biasing engagement, or blocking can be configured differently based on environmental conditions, panel size, and structural design. For instance, some implementations may define “strong wind” or “external force threshold” as wind speeds exceeding 10 m / s, while more robust constructions might set this threshold at 15 m / s or 20 m / s. Similarly, disengagement of a motor coupling or release mechanism may occur at 10 m / s in highly adaptive or sensitive panel designs, or may not occur until 20 m / s in heavy-duty systems.

[0708] Example Thresholds for Biasing Mechanisms

[0709] Low-Wind Continuous Bias (Starting at -5-10 m / s)

[0710] • Embodiment: A gentle spring that begins exerting a return force at low wind speeds (-5 m / s) and gradually increases up to 10 m / s.

[0711] • Rationale: Systems in mild climates or with lightweight panels that start reorienting at relatively low speeds.

[0712] Moderate Threshold Bias (Starting at -10 m / s)

[0713] Embodiment: A stiffer spring or weight arrangement that does not really permit rotation until wind exceeds -10 m / s. Rationale: More robust, designed for normal daily breezes to have minimal effect; the panel only yields or reorients under near-gale conditions.

[0714] Adaptive Bias at ~10 m / s

[0715] • Embodiment: A spring or magnet that starts to yield the panel around 10 m / s but locks firmly below 10 m / s for stable solar tracking.

[0716] • Rationale: A balanced approach that protects panels from moderate gusts but doesn’t react to every small breeze.

[0717] Example Thresholds for Disengagement / Release Mechanisms

[0718] Disengagement at ~10 m / s

[0719] • Embodiment: “Upon wind speeds reaching or exceeding ~10 m / s, the release mechanism decouples the motor from the vertical support, allowing free rotation.”

[0720] • Use Case: Very wind-sensitive sites or when the motor must be protected early.

[0721] Disengagement at ~20 m / s

[0722] • Embodiment: “For robust systems, the coupling remains engaged up to ~20 m / s. Beyond this threshold, the system automatically disengages to prevent excessive load.”

[0723] • Use Case: Installations in moderate climates that rarely see 20 m / s; heavier structure can handle up to that speed.

[0724] Automatic Re-Engagement

[0725] • Description: “When wind speed returns below the threshold (e.g., dropping below 15 m / s), the coupling re-engages, enabling normal motor-driven reorientation or sun tracking.”

[0726] • Note: Sometimes a slight hysteresis is built in (e.g., the release mechanism disengages at 15 m / s but re-engages at 12 m / s) to avoid rapid on / off cycling.

[0727] Example Thresholds for Blocking Mechanisms / Members

[0728] • Blocking Up to 15 m / s, Then Releasing

[0729] • E.g., a shear pin that breaks at ~15 m / s wind force, so the panel can rotate further beyond the normal limit in extreme gusts.

[0730] Blocking Up to 20 m / s, Then Swinging Away

[0731] A hinged pivot or wire that unlatches at ~20 m / s, fully freeing the panel to feather with the wind. According to some examples of the elongated arrangement, wind-responsive solar panels are arranged to hang from a wire, or a bar, that extends along the entire length of the elongated arrangement. The bar can be realized by an example of the solar cell rod disclosed herein.

[0732] In some examples, the elongated arrangement comprises at least two solar cell rods according to embodiments herein. With these examples, one or more respective wind-responsive solar panels are mounted to a respective one of said at least two solar cell rods. Each one of said at least two solar cell rods is connected, e.g. mechanically connected, to at least one other solar cell rod using at least one respective interconnecting line. This means that each solar cell rod connects to its neighboring solar cell rod, which can be one neighbor or two neighbors. The elongated arrangement thus forms a chainline structure of interconnected solar cell rods, where each solar cell rod holds at least one wind- responsive solar panel. The wind-responsive solar panel is described above.

[0733] The expression “extend between A and B” can, in some examples, refer to a feature, such as a line, rod, or the like, that extends all the way from A to B, or B to A, or the like.

[0734] According to at least some embodiments herein, the solar panel suspension system provides at least two suspension points, sometimes at least four suspension points. A pair of suspension points can be used to suspend e.g. the elongated arrangement that can be directly or indirectly mechanically connected between the pair of suspension points. Generally, one or more suspension points can be located at a suspension structure, such as a distal end of a beam, or the like. Notably, two suspension points can be located at different locations on a horizontal bar. Accordingly, two suspension points need not necessarily belong to e.g. different beams, even though the suspension points can belong to different beams.

[0735] Figure 1 shows an example of a solar panel suspension system 100 according to at least some embodiments herein. The solar panel suspension system 100 comprises two vertically, e.g. substantially vertically, mounted beams 105. The solar panel suspension system 100 can accordingly mount, such as suspend, one or more wind-responsive solar panels 400 to allow light incident thereon to be converted to electricity.

[0736] Each beam 105 is connected, directly or indirectly, to ground. In this manner, each beam 105 can be steadily secured in its position, e.g. in an upright position. This can mean that a main extension direction of each beam 105 is vertical, such as substantially vertical. Furthermore, each beam 105 is arranged to provide a respective suspension point 110, e.g. at a distal end 109 thereof. At least one elongated arrangement 600 can be suspended between two such respective suspension points 110, or suspension structures. The suspension structures can be part of the distal end of each beam 105. The distal end 109 can comprise a suspension point, i.e. such suspension point 110.

[0737] In some examples, Figure 1 shows an exemplifying solar panel suspension system 100 for suspending wind-responsive solar panels 400 above ground, thereby making the ground available. The ground can be made available, for example, by having the wind-responsive solar panels suspended at least 2 m, 3 m, 4 m, 5 m, 10 m, 20 m, 30 m, or the like, above the ground and / or by ensuring that the lowest part of the wind-responsive solar panels is at least 2 m, 3 m, 4 m, 5 m, 10 m, 20 m, 30 m, or the like, above the ground.

[0738] The solar panel system 100 comprises two suspension structures 130 indirectly connected to the ground and located at a distance from the ground, and an elongated arrangement 600 for mounting the wind-responsive solar panels 400. The elongated arrangement 600 is suspended and extends between the two suspension structures 130.

[0739] Figure 3 shows an example in which the solar panel suspension system 100 includes a number of elongated arrangements 600 that are arranged vertically above each other. In this manner, each elongated arrangement 600 is held at its respective height over ground.

[0740] Figure 4 shows a further example, illustrating that the two beams 105 can be connected to each other and then a further beam 103 connects the two beams 105 to ground. This is an example of the two beams 105 being indirectly connected to the ground.

[0741] Figure 5 is a variation of the embodiment according to Figure 4 and / or Figure 6 below.

[0742] Figure 6 is another example of a solar panel suspension system 100. The solar panel suspension system 100 comprises four beams 105. Each beam 105 of the four beams 105 is located at a respective comer of a rectangle. The four beams 105 can describe a 10 by 20 meters rectangle or the like.

[0743] In some examples, the solar panel suspension system 100 can be provided with a spacing bar 135 that can be arranged perpendicularly to multiple elongated arrangements 600 mounted in parallel. Each elongated arrangement 600 can thus be connected to, such as attached or fixed to, the spacing bar 135. As a result, the spacing bar 135 ensures that the distance between the elongated arrangements 600 remains constant, or almost constant. This can mean that the distance between two elongated arrangements 600 is constant, e.g. along a main extension direction of the two elongated arrangements 600.

[0744] Generally, the hosting bar 130 and the spacing bar 135 can be provided with holes, such as through- bores, inserts, holding units, or the like, for fastening of various details herein. These various details can refer to one or more of interconnecting line(s), solar cell rod(s), support wire(s), or the like.

[0745] The spacing bar 135 can be made of plastic, or other suitable material for providing rigidity and / or stiffness to the bar(s).

[0746] Generally, a beam length of the beams 105 can be between 2 to 10 meters, 4 to 6 meters, or the like. The beam length is dependent on how high above ground some lowest part of the wind-responsive solar panel 400 is allowed to be. Other beam lengths than those mentioned above can therefore also be applicable in some examples. A distance between two beams 105 can be 10 to 50 meters, 20 to 40 meters, or about 30 meters.

[0747] In general, the beams 105 can be made of wood, metal, plastic, or other common materials used for building beams. The beams can be built using truss, frameworks, cylinders, or the like. The beams 105 can be stiff and / or rigid, thereby avoiding, or reducing, flexing thereof.

[0748] Furthermore, with the solar panel suspension systems 100 herein, the panels are sometimes suspended high enough, as in the example above, to not be impacted by roaming animals, people, growing vegetation, etc., with the added benefit that the ground under the wind-responsive solar panels 400 is made available for use, such as for agricultural use, motorways, and / or the like.

[0749] At least some examples of the solar panel suspension system 100 described herein can be electrically connected to a load (not shown), such as an energy storage system, a battery system, a battery, a motor, an engine, a machine, an electrical grid, or the like. The motor, etc., can be used for any suitable purpose, such as air conditioning, ventilation, manufacturing, or more.

[0750] It shall be noted that Figure 6 illustrates an example where different aspects of the systems have been combined, while each aspect can also be applied separately to this or other examples herein. Accordingly, the system 100 of Figure 6 can also be realized while applying only one of the aspects, or any number of the aspects.

[0751] In some examples, Figure 6 shows an example of a solar panel suspension system 100 for suspending wind-responsive solar panels 400 above ground, thereby making the ground available.

[0752] The solar panel suspension system 100 comprises two elongated suspension structures 130 directly or indirectly connected to the ground and located at a distance from the ground. Moreover, the solar panel suspension system 100 comprises a first elongated arrangement 600 and a second elongated arrangement 600. The first elongated arrangement 600 comprises a first set of the wind-responsive solar panels 400, which can represent a first row of wind-responsive solar panels. The second elongated arrangement 600 comprises a second set of the wind-responsive solar panels 400, which can represent a second row. The first and second sets of wind-responsive solar panels 400 do not include the same wind-responsive solar panels, i.e. any wind-responsive solar panel 400 cannot be included in both the first and second sets. This means, for example, that the first and second sets are different, non-overlapping, etc. Consequently, both the first and the second sets of wind-responsive solar panels 400 are so-called proper subsets of the wind-responsive solar panels 400 included in, such as mounted by, held by, or the like, the system 100.

[0753] The first and second elongated arrangements 600 run transversally to the two elongated suspension structures 130, wherein each one of the first and second elongated arrangements 600 is suspended and extends between the two elongated suspension structures 130, wherein the first and second elongated arrangements 600 run alongside each other (e.g. without crossing each other). With reference to Figure 9a / 9b through Figure 19 and Figure 21 through Figure 25a / 25b, there are shown various examples of the solar panel suspension system 100 in which the angle of rotation is limited. These examples can be combined with any one or more of the exemplifying solar panel suspension systems 100 disclosed herein.

[0754] Figure 9a shows a detailed view of a wind-responsive solar panel 400 mountable in any example or embodiment of the solar panel suspension system 100 herein. In the examples of Figures 9a and 10, the wind-responsive solar panel 400 is held at an angle (e.g., defined in a plane perpendicular to the first direction X). Thanks to the angle, more of the light incident on a surface of the wind-responsive solar panel can be converted into electricity, e.g. due to a smaller portion of the light being reflected at the surface of the wind-responsive solar panel 400. This means that a greater portion of the light will eventually reach a photovoltaic cell of the wind-responsive solar panel 400. As a result, the efficiency of the solar panel suspension system 100 is increased.

[0755] Even when the wind-responsive solar panel(s) are held at the angle, wind can cause the wind- responsive solar panel to move, yet somewhat stronger wind may be required as compared to when the wind-responsive solar panel hangs completely free. In this regard, it is noted that the wind-responsive solar panel, even when held at the angle, is movable due to wind. Further, when held at the angle, the wind-responsive solar panel still extends toward the ground, yet its main directional plane is at an angle with respect to a vertical plane.

[0756] According to various examples herein, the solar panel suspension system 100 can thus allow the angle of the wind-responsive solar panel, such as a flexible solar panel, to be adjusted. This can be achieved by providing the solar panel suspension system 100 with an elongated support 140, which can be parallel with, or substantially parallel with, the main extension direction (X) of the elongated arrangement 600, such as the solar cell rod(s) 500, or the like. Generally, the elongated support 140 can be realized as a support wire, a support beam, a support bar, or the like.

[0757] In these examples, the elongated support 140 (such as a support line, a support bar, or the like) can be suspended along the first direction X (e.g. along the solar panel’s main extension direction 200). This means that the solar panel suspension system 100 can include the elongated support 140. The elongated support 140 has two ends, which can be provided (e.g. fastened) at a respective beam 105, or the like. As an example (albeit not shown), the suspension structure can be arranged to hold (e.g. fasten) the suspension line at a first point on the suspension structure. Further, the suspension structure can be arranged to hold (e.g. fasten) the elongated support at a second point on the suspension structure. The first point can be located further away from the ground than the second point. A distance between the first and second points can correspond to a length of the wind-responsive solar panel (e.g. along the second direction Y). Accordingly, the distance can be the same as the panel’s length, or slightly more or less, depending on implementation. The distance can be less than 1.5 times the length of the wind-responsive solar panel 400.

[0758] In Figures 9a, 9b, and 10, the solar panel suspension system 100 is arranged to provide the elongated support 140 within reach of the wind-responsive solar panel 400 (e.g. when the wind-responsive solar panel 400 swings due to wind). Thereby, the wind-responsive solar panel 400 can be prevented from assuming its natural, vertical position at rest. This means, for example, that the elongated support 140 prevents the wind-responsive solar panel 400 from hanging vertically due to its gravity, e.g. as long as a distal portion of the wind-responsive solar panel 400 rests on the elongated support 140 (e.g. lays on top of the elongated support 140). However, the elongated support 140 can also be used to limit the rotation of the wind-responsive solar panel outside a rotation interval. The elongated support 140 is thus an example of the blocking structure.

[0759] In some examples relating to Figures 9a, 9b, and 10, the wind-responsive solar panel 400 can be stopped from rotating beyond a particular rotation angle (if initially positioned, e.g., in a vertical resting position). In this manner, the wind-responsive solar panel 400 (or the elongated arrangement 600) can be held steadily at the particular rotation angle when the wind has a speed above a threshold value. Accordingly, while it has been observed that strong winds can cause turbulent and / or irregular movement of the wind-responsive solar panel 400, it has been realized that the construction according to Figure 9a can be applied as in Figure 9b. Figure 10 illustrates that the elongated arrangement 600 rests on the elongated support 140. It is, however, clear that the corresponding abutment between the distal portion 460 and the elongated support 140 can occur when the wind blows on the wind- responsive solar panel 400 (if initially in a vertical resting position). The corresponding abutment can refer to the distal port 460 abutting the elongated support 140 from below.

[0760] Expressed differently, in some embodiments, the blocking structure 700 is elongated. The blocking structure 700 is arranged along the elongated arrangement 600. The blocking structure can be suspended between two further suspension points (e.g. on the suspension structure). The two further suspension points can be located at a distance below the initially mentioned suspension point.

[0761] In this manner, the wind-responsive solar panel 400 moves due to wind within the rotation interval, but outside the rotation interval, further rotation is limited by the elongated support 140. As a result, the solar cells are not exposed to harmful fluttering and / or vibration, which could cause malfunction or failure in the wind-responsive solar panel 400.

[0762] Given that the solar panel suspension system 100 is arranged to allow the wind-responsive solar panels 400 (e.g. belonging to the elongated arrangement 600 or the like) to swing about a rotation axis R, that runs in parallel with the first direction X, a first distance between the rotation axis R and the elongated support 140 can be less than a second distance between the rotation axis R and the distal portion 460 of the wind-responsive solar panel 400. With reference to Figures 9a / 9b through 25a / 25b, various examples show how the solar panels 400 can be prevented from rotating beyond a particular rotation angle (e.g. in a vertical plane perpendicular to the rotation axis R of the solar panels 400). The particular angle can be measured from a horizontal plane or from a vertical plane. Beyond the particular angle, the blocking structure limits the rotation (i.e. outside the rotation interval).

[0763] In order to constrain the rotation to the particular angle, the system 100 is provided with a blocking structure 700 that can stop the rotation of the elongated arrangement 600 and / or the wind-responsive solar panels 400, which can hang freely (e.g. at two suspension points of the system 100).

[0764] Accordingly, the blocking structure is arranged to apply its limitation to the rotation of the wind- responsive solar panels 400 outside the rotation interval. As an example, the rotation of the solar panel(s) can be constrained (e.g. limited or confined) to a rotation interval. The rotation interval can preferably be twice the particular angle, e.g. two multiplied by the particular angle.

[0765] With the embodiments including the blocking structure 700, there is provided a solar panel suspension system 100 for suspending wind-responsive solar panels 400. The system 100 comprises two suspension points 110 (e.g. on a suspension structure) and an elongated arrangement 600 that is suspended and extends between the two suspension points 110. The elongated arrangement 600 comprises the wind-responsive solar panels 400. The elongated arrangement 600 is arranged to permit rotation of the wind-responsive solar panels 400 about a rotation axis R running along a main extension direction of the elongated arrangement 600 (i.e. in the direction of the x-axis).

[0766] Moreover, the system 100 comprises a blocking structure 700, 701, 702, 710, 711, 712, 730, 731, 732, 140 arranged to, for example, apply its limitation to the rotation of the wind-responsive solar panels 400 only outside a rotation interval, and preferably not apply its limitation within the rotation interval.

[0767] Generally, the blocking structure according to the examples herein is arranged at a position (e.g. in space, in the vicinity of the solar panel) to hold and / or abut a distal portion of the elongated arrangement 600 (e.g. a distal end / edge of the solar panel) when the wind-responsive solar panels 400 are subjected to wind (e.g. above a threshold value).

[0768] In some examples, the blocking structure 700, 701, 702, 710, 711, 712, 730, 731, 732, 140 is arranged to stop or at least limit rotation of the wind-responsive solar panels 400 when subjected to wind (e.g. above a threshold value) at a rotation angle (801) relative to a rest angle (802) at which the wind- responsive solar panels 400 are located when subjected to wind below a further threshold value.

[0769] In some examples, the blocking structure limits the freedom of rotational movement of the elongated arrangement 600, the wind-responsive solar panel 400, or the like.

[0770] In Figures 9a and 9b, the elongated support 140 is an example of the blocking structure. Then, this means that the distal portion (460, 610) of the wind-responsive solar panel 400 and / or the elongated arrangement 600 can abut the elongated support 140 when the wind-responsive solar panel 400 and / or the elongated arrangement 600 is at one of the endpoints of the rotation interval. The elongated support 140 is thus arranged to stop the rotation at the rotation angle when the distal portion (460, 610) abuts the elongated support 140.

[0771] In some embodiments, the rotation interval is defined such that at an endpoint, a distal portion of the elongated arrangement 600 abuts the blocking structure 700 and / or such that the blocking structure 700 is arranged to begin applying the limitation of the rotation at the endpoint of the rotation interval. This limitation can imply that the rotation of the elongated arrangement 600 (or the solar panel) can slow down from or after the endpoint of the rotation interval up to a limit (e.g. where the solar panel stops rotating).

[0772] With the embodiments in which the rotation angle is limited, it may be that the angle at which the limitation can be applied is in a range from 45 to 90 degrees, 60 to 90 degrees, or 70 to 85 degrees (e.g. with respect to a vertical plane). Consequently, an interval corresponding to the angle can be twice as large due to the panel typically rotating symmetrically away from a vertical plane. In some examples, the panel can rotate non-symmetrically.

[0773] In Figure 11, there is a detailed view illustrating that the system 100 can include a blocking structure 700 (e.g. realized as an elongated blocking structure, such as a beam, a bar, a wire, a line, a string, or the like). The elongated blocking structure 700, 701 can be suspended at a plate 770 connected to the suspension structure 130. The plate 770 can be comprised of, e.g. be part of, the elongated arrangement 600. The plate 770 can thus be arranged to rotatably mount and suspend one end of the elongated arrangement 600 to one of the suspension points 110 (e.g. of the suspension structure 130). The examples of Figure 11 can be combined with any one or more of the embodiments herein, when applicable. Thanks to the plate 770, a consistent distance between the elongated blocking structure 700, 701 can be achieved. This distance can be constant, or almost constant, along the extension direction of the blocking structure 700, 701 and the elongated suspension structure 130.

[0774] In Figure 12a, the blocking structure 700 is realized by the elongated blocking structure 701 that interacts with a longitudinal protrusion 711 of the solar panel 400. The longitudinal protrusion (711) can be part of a stiff structure running along a lower periphery of the solar panel 400. It is desired that the longitudinal protrusion 711, 712 extends beyond the solar panel 400 as seen along the longitudinal direction (e.g. the x-axis) of the solar panel 400.

[0775] Figure 12b is provided to illustrate that the elongated arrangement 600 can swing or rotate either clockwise or counter-clockwise, preferably while the solar panels pass under an upper portion of the elongated arrangement 600. The fact that the elongated arrangement 600 can swing back and forth in this manner is applicable to some embodiments herein.

[0776] In the examples of Figures 12a and 12b, the blocking structure 700 is elongated (i.e. it can be a wire, or the like) and is arranged transversally to the elongated arrangement 600. The elongated arrangement 600 comprises a longitudinal protrusion 711, 712 that is arranged to abut the blocking structure 700 when the elongated arrangement 600 is forced to the ends of the rotation interval. The longitudinal protrusion can extend beyond at least one solar panel in a longitudinal direction of the elongated arrangement. The blocking structure can be suspended between two additional suspension points (e.g. on the suspension structure).

[0777] Figure 13a illustrates an example of the system 100 in which the blocking structure 700 is suspended along the respective wire 130. The blocking structure 700 is suspended at respective points of the suspension structure located below the suspension points of the respective wire 130.

[0778] Figure 13b illustrates further examples of the system 100, in which the wind-responsive solar panel and / or the elongated arrangement 600 is provided with one or more openings 745 (such as slots, slits, through-holes, or the like). The openings 745 (i.e. the cross-section thereof in the xy-plane) can have various shapes (such as elongated, elliptical, rectangular, or the like). The elongated blocking structure 700 can pass through the openings 745 (such as a respective opening in case there are several elongated blocking structures 700). In this fashion, as wind causes the elongated arrangement 600 to rotate, an inner lower portion of the opening 745 abuts the blocking structure 700, thereby limiting the rotation outside the rotation interval.

[0779] Figure 14 shows another example of when the blocking structure 701 is arranged transversally with respect to the main extension direction of the elongated arrangement 600. In this example, the wind- responsive solar panel 400 is not subjected to wind, or wind that is below a threshold value. In contrast, Figure 15a shows the wind-responsive solar panel 400 when subjected to wind (e.g. wind that is greater than a threshold value). In this case, the longitudinal protrusion 711, 712 abuts the blocking structure (at least a portion thereof).

[0780] Turning back to Figure 13a, the system 100 can further include a further blocking structure 703 (such as a wire) that is suspended between a respective longitudinal support structure 741, 742. The respective longitudinal support structure 741, 742 can be a stiff beam, a wire, or the like. The respective longitudinal support structure 741, 742 extends between two distal portions of a respective beam 105. The further blocking structure 703 can be arranged in level (e.g. in vertical level) with the blocking structure 701, 702. In some examples, the further blocking structure 703 can be arranged slightly above (i.e. when considering the distance from the ground) the blocking structure 701, 702. This can be beneficial when the distal portion of the solar panel 400 is flexible (i.e. it can bend such that — with reference to Figure 15a — the longitudinal protrusions 711, 712 are located closer to the ground than a central portion of the distal edge 610 of the elongated arrangement). This applies when the elongated arrangement 600 is subjected to wind above the threshold value (i.e. sufficiently to bend said distal portion 610). Figure 15b reveals that, in some examples, the distal portion 610 of the elongated arrangement 600 can be provided with an engagement element 781, 782 (such as a hook, a clasp, a latch, a spike, a buckle, a fastener, a snap, a button, a loop, a magnet, a catch, a toggle, a pin, a rivet, or the like). This example can be combined with any one or more of the examples herein. Thus, in some embodiments, at least one (preferably both) of the longitudinal distal ends of the distal portion is provided with an engagement element 781, 782, thereby reducing the risk that the elongated arrangement breaks free from the blocking structure 700 when the distal portion 610 flexes.

[0781] Figure 16 illustrates an example of the system 100, in which the system 100 is subjected to little or no wind to the left (in Figure 16) and strong wind to the right (in Figure 16). In this example, the system 100 comprises the further blocking structure 703, which can be suspended as shown in Figure 13a, or in another similar manner. Thanks to the further blocking structure 703, the length of the elongated arrangement 600 can be longer than it would be without the further blocking structure 703. The further blocking structure 703 provides beneficial support to a central portion of the elongated arrangement 600, which thus can withstand greater stress (e.g. due to wind). The further blocking structures 700,

[0782] 703 can be arranged to abut a central portion 713 of the elongated arrangement 600 when the elongated arrangement 600 is forced to one of the ends of the rotation interval. In order to achieve that the central (and preferably distal) portion of the elongated arrangement 600 can abut the further blocking structure 703, the solar panel can be provided with a through-hole (e.g. a slot). The further blocking structure 703 can be arranged to run through the through-hole, irrespective of the rotation angle of the solar panel.

[0783] In Figure 17a, another example of the system 100 is shown, in which the system 100 comprises an additional blocking structure 704. The additional blocking structure 704 is elongated and is arranged transversally to the elongated arrangement 600. The elongated arrangement 600 comprises an additional longitudinal protrusion 721, 722 that is arranged to abut the additional blocking structure

[0784] 704 when the elongated arrangement 600 is forced to the end(s) of the rotation interval. The additional blocking structure 704 can be located closer to the solar panel 400 than the blocking structure 701 in a longitudinal direction.

[0785] Thanks to the additional blocking structure 704, bending of the solar panels of the elongated arrangement 600 can be reduced. As seen in Figure 17a, it has been realized that the solar panels may bend when further rotation of the solar panel is limited or stopped by the blocking structure 701, yet the wind continues to push on the solar panel. Such wind pressure could cause the solar panel to bend about a geometric axis that is parallel with the main extension direction of the elongated arrangement and runs below the additional blocking structure 704. The additional longitudinal protrusion 721, 722 can extend beyond at least one solar panel in a longitudinal direction of the elongated arrangement, but the additional longitudinal protrusion 721, 722 extends a shorter distance from the solar panel than the longitudinal protrusion 711, 712.

[0786] In another example of the system 100, when subjected to no wind (Figure 18) and when subjected to wind (Figure 19), the rotation of the solar panel 400 can be achieved by a blocking structure 730 that is included in the elongated arrangement 600 (e.g. as the distal end of the solar panel). The blocking structure can then comprise a distal, lateral protrusion 731, 732 extending transversally to a main extension plane of the solar panels 400. The distal, lateral protrusion 730, 731, 732 is arranged to abut an elongated suspension structure 130 when the elongated arrangement 600 is forced to the end of the rotation interval. In some examples, the system 100 can be provided with an additional wire 701, 702 (e.g. as shown in Figure 16). Then, the distal, lateral protrusion 731, 732 can be arranged to abut the additional wire 701, 702 when the elongated arrangement 600 is forced to the end of the rotation interval. Advantageously, an upper surface of the distal, lateral protrusion 731, 732 can be provided with a mirror. In this manner, the distal, lateral protrusion 731, 732 acts as both a blocking structure and a mirror to improve the efficiency of the solar panel system 100.

[0787] Figure 21 and Figure 22 show an example in which the solar panel 400 comprises at least two sections. In this example, three sections are shown. As before, Figure 21 shows the system 100 with no wind and Figure 22 shows the system 100 when subjected to wind. Accordingly, in some embodiments, a distal portion of the solar panel 400 is configured to allow the longitudinal distal ends of the distal portion to be offset relative to a central portion of the distal portion. The central portion is arranged to be offset relative to a geometric line through the longitudinal distal ends of the distal portion when the solar panel 400 is subjected to wind and reaches the end of the rotation interval. In these embodiments, optionally in combination with other embodiments herein, the solar panel can be sectional or flexible in order to enable the offset of the central portion.

[0788] In some embodiments, the distal portion is flexible. In some embodiments, the distal portion comprises one or more stiff sections (e.g. flexibly connected to each other, with a flexible material, a joint, or the like).

[0789] Figure 23a shows an example of the system 100 in which the blocking structure is stiff and / or rigid (such as a beam, bar, rod, etc.). The blocking structure 750 can include a first bar and a second bar, having a first portion 751 and a second portion 752 at a respective end thereof. The other ends of the first and second bars can be fixedly connected to each other.

[0790] The first and second portions 751, 752 are arranged such that the distal portion of the elongated arrangement 600 abuts one of the first or second portions 751, 752 when the elongated arrangement 600 is forced to any one of the ends of the rotation interval. Expressed differently, the blocking structure 750 can be arranged to allow the distal portion of the solar panel to abut the first or second portion 751, 752 when the elongated arrangement 600 is forced (e.g. by wind) to the respective end of the rotation interval. Notably, the solar panel need not necessarily be provided with the longitudinal protrusion 711, 712 (see the left comer of the wind-responsive solar panel). The first and / or second portion 751, 752 can abut a respective distal comer of the elongated arrangement 600 (e.g. a distal comer of the solar panel). Here, “distal” is relative to the rotation axis and the center of the elongated arrangement and / or the solar panel. As shown in the figure, the second portion 752 can abut directly onto the solar panel, which does not need to have any longitudinal protmsion 711, 712.

[0791] The shape of the blocking structure 750 can vary, but it is preferably configured to provide the first and second portions 751, 752 to achieve constrained rotational movement of the solar panel to the rotational interval (e.g. as achieved by abutment on the distal portion of the elongated arrangement 600). The blocking structure 750 can have the shape of a straight beam, an upside-down letter “V”, a combination thereof, or the like.

[0792] In some examples, the distal portion of the elongated arrangement 600 is provided with a longitudinal protmsion 711, 712 as mentioned above. Similarly, the longitudinal protmsion can interact with (i.e. abut) the first and second portions 751, 752 when the ends of the rotation interval are reached.

[0793] Figure 23b is a perspective view, illustrating that at least portions of the blocking stmcture 701, 702 (e.g. a wire or the like) can run askew with respect to a transversal direction to the elongated arrangement 600. In this manner, the limitation of the rotational freedom of the solar panels can be achieved by having the distal comers of the solar panel abut the blocking stmcture 701, 702. The distal comers are distal relative to the center of the solar panel and to the rotation axis of the elongated arrangement 600. It can be that the distal comers are provided with the engagement elements 781, 782 as described above. In order to achieve that the blocking stmcture runs askew, a holder 785 can be provided. The holder 785 can be connected between two blocking structures (e.g. wires), whereby the blocking structures become askew. The holder 785 can be a connector, bar, wire, or the like. The length of the holder 785 is adapted based on the desired angle of the askew blocking stmcture, or at least the askew parts of the blocking stmcture 700. An advantage is that blocking becomes possible without the need for, e.g., the protmsions 711, 712, as the blocking stmcture can abut the distal comers of the elongated arrangement 600 when the rotation interval is reached (e.g. due to wind).

[0794] In some examples, there can be more than one holder 785 (e.g. a first holder 785 and a second holder 785). The holders 785 can have the same or different lengths.

[0795] The blocking stmcture 700 can be mounted at the beam 105 (e.g. at a suspension point 786). In some examples, the blocking stmcture 700 can be fastened as shown in Figure 11. In general, it is preferred that the blocking stmcture 700 is fastened below the rotation axis and below the suspension points of the suspension stmcture in which the elongated arrangement 600 is suspended. In some examples, the system 100 comprises two or more elongated arrangements 600 that are positioned along each other (e.g. parallel to each other). Then, the blocking structure 700 can form a zigzag pattern (i.e. at least portions of a projection of the blocking structure on a horizontal plane can form a zigzag pattern).

[0796] The holder(s) 785 can preferably be located at a distance from the rotation axis of the elongated arrangement 600. The distance can be adapted based on the distance from the rotation axis to the distal portion of the elongated arrangement 600. The distance can be slightly greater than said length. However, as a variant of the embodiments with the elongated support 140, the distance can be slightly less than said length. In the example depicted in Figure 23b, the holder 785 is located centrally between the first and second elongated arrangements 600.

[0797] Figure 24 illustrates that one of the first and second portions 751, 752 is connected to a distal end of a beam 105 that connects to the ground. Sometimes, both first and second portions 751, 752 are connected to the distal end, or even to a respective distal end in the case the beam 105 provides two distal ends (or if there is a second beam adjacent to the aforementioned beam).

[0798] Figure 25a illustrates further examples of the system 100, in which the blocking structure 700 is realized by one or more lines 760 (e.g. wires, ropes, strings, cables, cords, threads, filaments, strands, ribbons, tapes, bands, strips, or the like). Generally, the blocking structure is elongated and flexible. The lines can have the same, similar, and / or corresponding features, or they can have different features, selected from the examples herein. For simplicity, a single line of said one or more lines 760 is considered. One end of the line 760 can be connected to (e.g. fixed to, mounted on) a portion of the beam 105. The other end of the line 760 can be connected to the distal portion 610 of the elongated arrangement 600.

[0799] More generally, also with reference to Figure 25, according to some examples, the blocking structure 700 comprises a flexible elongated member 760 (e.g. a line) that is connected to the distal portion 610 of the elongated arrangement 600 and to a fixed point 765 located below (at least along the vertical direction) the distal portion’s 610 location when not subjected to wind.

[0800] In some embodiments, the fixed point 765 is located at the suspension structure (e.g. a beam 105) or the like. In some embodiments, the fixed point 765 is attached to the suspension system of the solar panels (e.g. a lower part of the beam 105) or is located on the ground in the vicinity of, or in, an area beneath the solar panels.

[0801] The portion of the beam 105 at which the end of the line 760 can be connected can extend from the ground up to a particular level on the beam 105. The particular level can preferably be at or lower than a point on the beam that is at the same level as or lower than (i.e. in terms of distance from the ground) the other end of the line 760 when the elongated arrangement 600 is at the end of the rotation interval. Expressed differently, the particular level can be lower than a point given by a projection of the other end’s projection on the beam when the elongated arrangement 600 is at the end of the rotation interval.

[0802] In some examples, the particular level can be at the same level or lower than (i.e. in terms of distance from the ground) the other end of the line 760 when the elongated arrangement 600 is at rest (e.g. vertical, at a preset angle, or the like).

[0803] In some examples, the particular level can be located in the vicinity of the ground. In this manner, the rotation interval can be conveniently adjusted by a person (e.g. an operator or user) standing on the ground. The rotation interval is thus adjusted by adjusting the length of the line between the fastening points at the beam (or at the ground) and the elongated arrangement 600. However, the rotation interval can be adjusted in this manner in any embodiment herein, though the adjustment may be less convenient if the fastening point at the beam 105 is difficult to reach (e.g. requiring a ladder).

[0804] There can be any number of lines 760 arranged (e.g. connected, mounted, or the like) as described herein. Sometimes, a line can extend from one fastening point at one of the beams 105 to another fastening point at the other beam 105 while passing the distal portion of the elongated arrangement. At the passage of the elongated arrangement 600, the line can be fixed or can run through a hole, or the like.

[0805] Figure 25b illustrates a still further example of the system 100. In this example, the blocking structure 700 is arranged and / or configured to prevent the wind-responsive solar panel from assuming a vertical position, e.g. when a main extension plane of the wind-responsive solar panel is parallel with a vertical plane. This is achieved by a flexible elongated member 761, which can be similar to the one mentioned above in relation to Figure 25a, in combination with a protruding element 763 of the elongated arrangement 600. In this manner, the solar panel can assume a desired angle with respect to a vertical plane, e.g. at least when not exposed to winds that are strong enough to displace the solar panel from its resting position at the desired angle. The resting position is assumed to due gravity and the combination of the protruding element and the flexible elongated member, e.g. as mentioned together prevent further downward movement, or rotation.

[0806] In some examples, the protruding element extends from a rotation axis of the elongated arrangement 600, e.g. in a direction that is traverse, e.g. perpendicular, with respect to a main extension plane of the solar panel. For purposes of illustration, the wind-response solar panel to the right in Figure 25b hangs freely and thus assumes a vertical position. An angle between the main extension plane of the solar panel and the protruding element can be in an interval of 45-90 degrees, 50-90 degrees, 60-90 degrees, 70-90 degrees, 80-90 degrees, or the like. Notably, e.g. when said angle is 92 degrees, it is the same as that the angle is 88 degrees, and this applies for any example of the angle above 90 degrees. However, it can still be preferred that the protruding element 763 lies in a plane that is perpendicular to the rotation axis of the elongated arrangement 600. Therefore, in some examples, the blocking structure 700 comprises a flexible elongated member 761 that is connected to a protruding element 763 of the elongated arrangement 600 and to a fixed point 764 located at a suspension structure 130 or a beam 105 of the solar panel suspension system 100. The protruding element can be a shaft, a pin, a rod, a beam, or the like. The protruding element 763 may preferably be rigid and / or stiff. However, some flexibility can sometimes be beneficial, e.g. in order to dampen a blocking action achieved by the flexible elongate member 761 and the protruding element 763. Typically, each end of the elongated arrangement 600 can be provided with a respective blocking structure 700 of this kind, i.e. for each end there is a respective protruding element and a respective flexible elongated member.

[0807] The fixed point 764 can preferably be located on the beam 105, and e.g. at a portion thereof that may be selected such as that a length of the flexible elongated member 761 is from a minimum length up to e.g. 200%, 180%. 150%, 130%, or the like, of the minimum length.

[0808] The minimum length can be determined based on the desired angle, below which the solar panel should not rotate, and a position, on the protruding element 763, at which position one end of the elongated flexible element 761 is fastened. This means that the fixed point can be located in an interval spanning a number of suitable positions at different vertical positions, e.g. with respect to the ground (not shown).

[0809] As described above, one end of the flexible elongated member 761 is connected at the fixed point 764. The other end, or another portion, of the elongated member 761 can be connected to the protruding element 763, e.g. at a portion thereof. The portion includes a connection point 762 of the protruding element 763 at which connection point 762 said other end of the flexible elongated member 761 can be fastened. The portion can be a distal portion, e.g. where distal is understood in relation to the protruding element’s fastening point at the elongated arrangement 600. The portion can be located at the middle of the protruding element 763. At any rate, an effective length of the protruding element 763 is from a fastening point at the elongated arrangement 600 to the portion, such as to the connection point 762, or the like, where the other end of the elongated member 761 is fastened at the protruding element 763. Then, as an example, the portion can be defined as being located at a distance, corresponding to the effective length, from the fastening point, i.e. at an effective distal end of the protruding element.

[0810] Furthermore, it can, at least according to some examples, be that the desired angle is determined by a combined effect achieved by the length from the elongated arrangement 600 along the protruding element 763 to the connection point 762, the length of the flexible elongated member 761, the fixed point’s 764 position on the beam 105 and / or on the suspension structure 130, the protruding element’s angle relatively the main extension plane of the elongated arrangement 600. In addition, the protruding element may be straight, curved, have one or more angles between straight portion forming the protruding element, etc. That is to say, one and the same desired angle may be achieved by a plurality of combination of these aforementioned variables, and / or similar variables, that determines the desired angle.

[0811] With reference to Figure 26, examples of the rotation interval are described. These examples are generally applicable to the examples of the blocking structure described herein. Figure 36 illustrates a plan view in the yz-plane as seen along the longitudinal direction of the elongated arrangement 600, the wind-responsive solar panel, and the like. An angle of rotation can be defined as being zero (e.g. when the wind-responsive solar panel is vertical, such as when not exposed to wind, at least in some examples). However, the angle defined as zero can be defined in many other ways. With zero on a vertical direction, the interval can, for example, be from -60° to 60°, from -70° to 70°, from -80° to 80°, from -85° to 85°, or the like. These are all examples of symmetric intervals; however, non- symmetric intervals can also be chosen. As explained earlier, the angle at which rotation can be limited (e.g. stopped, prevented, or inhibited) can range from, for example, 45°, 60°, or 70° up to, for example, 110°, 100°, 90°, 85°, or the like.

[0812] In some embodiments, possibly combined with other embodiments herein, the blocking structure 700 comprises a shock-absorbing material at least at portions of the blocking structure 700 that are arranged to abut the elongated arrangement 600 when located outside the rotation interval. Examples of shock-absorbing materials include rubber, foam, gel, silicone, elastomer, neoprene, polyurethane, or the like.

[0813] Figure 27 and Figure 28 illustrate that, in some examples, the limitation of the rotation interval can be achieved by providing the beam 105 with at least one (preferably two) stop heels 106 (e.g. at its distal end). Each of the stop heels 106 can be arranged to limit the rotation of the elongated arrangement 600 (e.g. at 90°, 85°, 80°, 75°, 70°, or the like). This can be achieved by having the elongated arrangement 600 comprise a bar portion 602 that can be received by a hole 170 at the distal end of the beam 105, wherein the bar portion 602 includes a projecting element 601. The projecting element 601 is arranged to limit the rotation outside the rotation interval. This means, for example, that when the elongated arrangement 600 has rotated to the end of the rotation interval, the projecting element 601 abuts one of the stop heels 106.

[0814] Figure 29 illustrates that the elongated arrangement 600 (including the wind-responsive solar panels) can include at least one bar element (preferably two bar elements). A bar element can be any element that is shaped as, at least to some extent, a bar. Each bar element can be arranged (e.g. provided, located, or the like) at a respective end of the elongated arrangement 600. The elongated arrangement 600 can include a bar element that runs along an upper portion of the elongated arrangement 600. Explicitly, the elongated arrangement 600 must not, even if possible in some examples, include a single bar that extends from one end of the elongated arrangement 600 to the other end of the elongated arrangement 600.

[0815] From Figure 20, it can be seen that each solar rod assembly 200 or elongated arrangement 600 can include one or more respective solar panels 400 and a respective solar cell rod 500 for each of the solar panels 400. As explained above, an exemplifying elongated arrangement 600 can include a number of solar rod assemblies 200 that are interconnected using interconnection lines 120, thereby forming rows of wind-responsive solar panels 400.

[0816] Furthermore, Figure 20 illustrates that a suspension structure can be a distal end 109 of a beam 105 or a suspension bar 130 (extending into the plane of the paper). A distal portion 610 of the elongated arrangement 600 can be the lowest portion of the elongated arrangement 600 (e.g. when positioned at a predefined angle).

[0817] Moreover, the solar panel suspension system 100 comprises a first elongated arrangement 600 that is provided with a first set of wind-responsive solar panels 400 (which extend toward the ground) and a second elongated arrangement 600 that is provided with a second set of wind-responsive solar panels 400 (which extend toward the ground). The first and second sets of wind-responsive solar panels 400 are non-overlapping (i.e. no wind-responsive solar panel 400 is included in both sets). This means, for example, that the first and second sets are different, non-overlapping subsets of the wind-responsive solar panels 400 included in (or mounted by, or held by) the system 100.

[0818] The first and second elongated arrangements 600 run transversally to the two elongated suspension structures 130, wherein each of the elongated arrangements 600 is suspended and extends between the two elongated suspension structures 130, running alongside each other (e.g. without crossing each other).

[0819] An advantage is that a very large area above the ground can be used for suspension of solar panels, while at the same time few and / or slender beams take up valuable ground space. Additionally, the solar panel suspension system may be sufficiently steady and / or rigid to withstand rough weather conditions (e.g. rain, wind, hail, etc.).

[0820] In more detail, each end of the horizontal elongated support structure can be connected to a respective distal end 109.

[0821] Furthermore, the two parallel, horizontal elongated support structures 130 and the first and second elongated arrangements 600 can span a surface that is at least partly horizontal (substantially horizontal or the like). The surface can be a plane. When the two parallel, horizontal elongated support structures 130 are embodied, for example, as two wires 130, each of which can describe a parabolic graph due to being suspended (an almost straight line or the like), this is advantageous because a wire can be hung in a parabolic fashion between two supporting structures, even when the distance between them is very long, while still supporting the weight of the wire and the other parts of the solar panel suspension system (e.g. wind-responsive solar panels, rods, etc.).

[0822] In some embodiments, each of the two parallel, horizontal elongated support structures 130 comprises a respective wire 130.

[0823] In some embodiments, each of the two parallel, horizontal elongated support structures 130 is at least 25 meters, 35 meters, or 50 meters in length.

[0824] In some embodiments, the first and second sets of wind-responsive solar panels 400 extend toward the ground from a respective bottom surface 531 of the first and second elongated arrangements 600.

[0825] In some embodiments, each elongated support structure 130 is suspended between the respective pair of distal ends 109 (e.g. by means of a suspension line 115, 116 at each distal end 109).

[0826] In some embodiments, each of the first and second elongated arrangements 600 comprises a respective rod 500 that extends between and connects to (directly or indirectly) the two elongated support structures 130. The respective rod 500 is provided with the first or second set of wind-responsive solar panels 400, respectively. Each wind-responsive solar panel 400 of the first and second sets extends toward the ground from a respective bottom surface 531 of the respective rod 500, with the bottom surface 531 facing the ground.

[0827] In some embodiments, each of the first and second elongated arrangements 600 comprises a respective set of interconnectable solar rod assemblies 200. Each solar rod assembly 200 comprises a respective rod 500 having a respective line holding portion 520 at each end. The rod 500 is provided with a respective set of wind-responsive solar panels 400, which extend toward the ground from the bottom surface 531 of the rod 500. Each of the first and second elongated arrangements 600 comprises at least two suspension lines 115, 116 arranged to suspend the set of interconnectable solar rod assemblies 200 between the two suspension structures 130 by being connected to the respective line holding portion 520 at each end of the rod 500. In these embodiments, each elongated support structure 130 can be realized by a suspension bar.

[0828] In some embodiments, the solar panel suspension system 100 comprises a third elongated arrangement 600 that is provided with a third set of wind-responsive solar panels 400, which extend toward the ground. Each of the first, second, and third elongated arrangements 600 comprises three respective solar cell rods 500. Each of the three solar cell rods 500 is provided with the first, second, and third set of wind-responsive solar panels 400, respectively. The third elongated arrangement 600 can have the same, similar, or corresponding features as the first and / or second elongated arrangements 600.

[0829] In some embodiments, the respective rod 500 of at least one of the solar rod assemblies 200 of the set is defined by any one of the examples thereof. In some embodiments, at least one wind-responsive solar panel of the respective set of wind- responsive solar panels 400 of at least one of the solar rod assemblies 200 is defined by any one of the examples thereof.

[0830] Thus, in some examples, there is provided a solar panel suspension system 100 for suspending at least one wind-responsive solar panel 400 above ground, thereby making the ground available. The solar panel suspension system 100 comprises at least two beams 105 that are spaced apart. Each beam 105 has a non-zero vertical directional component.

[0831] Furthermore, the solar panel suspension system 100 comprises an elongated arrangement 600 that is provided with at least one wind-responsive solar panel 400 (which extends toward the ground, e.g. from the groove 510 of the solar cell rod 500). The elongated arrangement 600 extends between at least two beams 105 by being connected (directly or indirectly) at a respective distal end 109 of each beam 105. The elongated arrangement 600 can be said to be suspended between the respective distal ends 109 of the beams 105. Each distal end 109 can comprise a respective suspension point (or the suspension point can be located at, or on, the distal end 109).

[0832] According to further examples, the solar panel suspension system 100 can be arranged to biasedly hold the wind-responsive solar panel 400 toward a predefined rotation angle. Furthermore, the system 100 is arranged to biasedly hold the wind-responsive solar panels 400 toward the predefined rotation angle within a bias interval, and to apply little or no biasing of the wind-responsive solar panels 400 toward the predefined rotation angle outside the bias interval.

[0833] Advantageously, the biasing maintains the wind-responsive solar panels at a predefined angle (e.g. with respect to a vertical plane or another reference), even when the solar panels are subjected to wind (e.g. up to a threshold value). Thus, when the wind is stronger (e.g. above the threshold value), the wind-responsive solar panel rotates away from the predefined angle. In addition to wind, other factors (such as snow, tilt of the system, or the like) can cause the wind-responsive solar panels to leave the predefined angle. This helps prevent the wind from damaging or degrading the solar panel (e.g. in terms of mechanical and / or electrical malfunction).

[0834] It is preferred that the predefined angle is selected to achieve improved (e.g. optimal or near-optimal) efficiency of the solar panel’s conversion of light to electricity, as compared to when the predefined angle is not consciously selected.

[0835] The biasing of the solar panels 400 via a biasing structure 30 can be achieved by mechanical bias (e.g. using springs) or similar means. The biasing can also be achieved by one or more magnetic fields generated by a magnet (e.g. a permanent magnet, an electromagnet, or the like). Still further, the biasing can also be achieved by gravity acting as a dominating biasing factor. According to some embodiments herein, the biasing can be achieved by a combination of the cross- sectional shape of the shaft and the holding element, which causes gravity to influence the biasing to different extents at different angles or within different angle intervals.

[0836] For example, when the wind-responsive solar panel has a current rotation angle within the bias interval, the biasing structure will help return the wind-responsive solar panel to the predefined rotation angle. However, in some examples, the wind-responsive solar panel may return to the predefined rotation angle even when its current rotation angle is outside the bias interval (e.g. due to gravity or other forces not derived from the biasing structure). If the wind is too strong, it may be that the wind-responsive solar panel cannot return to the predefined rotation angle.

[0837] In some examples, the system 100 can be arranged to allow the wind-responsive solar panels 400 to rotate freely with respect to the biasing applied by the system 100 outside the bias interval.

[0838] In some examples, the system 100 can be arranged to allow the wind-responsive solar panels 400 to be freely rotatable in at least a free rotation interval outside the bias interval. The free rotation interval can have an extension of 0, 5, 10, 70, 80, or 90 degrees, or another suitable value depending on the application. Here, “extension” refers to a length (expressed in degrees) of the free rotation interval (i.e. not defined by a start and an end point). With reference to the angular coordinate system of Figure 26, the start point can be ±10°, ±20°, ±30°, or the like, and the end point can be ±90°, ±80°, ±70°, or the like.

[0839] Notably, the general features of the system 100 described above are also applicable in the following sections. Furthermore, it should be noted that any of the examples relating to the blocking structure can be combined with any of the examples relating to the biasing structure when reasonably possible.

[0840] Figure 31 illustrates an example of the elongated arrangement 600. Generally, with the embodiments herein, the elongated arrangement 600 comprises a suspension part 771 (such as the plate 770) and a solar panel part 772 (such as the shaft 790, which can be hollow or homogeneous, depending on the realization). The wind-responsive solar panels are fixedly connected to (e.g. mounted, integrated with) the solar panel part 772. Accordingly, the solar panel part 772 includes or is provided with the wind- responsive solar panels 400.

[0841] Figure 31 further shows that the elongated arrangement 600 can include a respective plate 770 at each end. The respective plate 770 can be fixedly connected to a respective one of the two suspension points 110, as illustrated in the examples herein.

[0842] In the example of, e.g., Figures 31 and 32, it can be seen that an aperture 780 is formed by the inner surfaces 787 of the plate 770. The inner surfaces can form a shape (in a cross-section, e.g. in the yz- plane) that can be described as a union of a partially oval primary part 788 (such as a circular or elliptical part) and a partially oval secondary part 789 (such as a circular or elliptical part). The partially oval secondary part 789 can be arranged to create a pit (e.g. in the cross-section) where the pit extends the aperture beyond a boundary of the partially oval primary part 788.

[0843] Figure 33 shows one example of where the biasing structure 800 (e.g. the inner surfaces 787, as described above) is combined with the blocking structure 700, according to one or more examples above. There are, of course, many other combinations of the examples of the biasing structure 800 and the examples of the blocking structure 700.

[0844] Figure 34 shows another example, in which the plate 770 is provided with a protrusion 777 that extends toward the center of the primary part 788 (as seen in a cross-sectional yz-plane). The plate 770 is an example of the holding element. The protrusion 777 can extend from the inner surface 787 of the primary part 788 (e.g. at a position selected to prevent rotation of the solar panels outside the rotation interval). The protrusion 777 is an example of the blocking structure, since it can be configured to stop rotation of the shaft 790 when a secondary projection 796 of the shaft abuts the protrusion 777. The secondary projection 796 can be arranged (as seen in a cross-sectional yz-plane) to project beyond a border of a primary portion 795 of the cross-section of the shaft, where the cross-section contributes to forming the biasing structure.

[0845] Figure 35 illustrates an example of the solar panel part 772 (such as the shaft 790). The shaft 790 does not necessarily extend between the two plates shown in Figure 31. The shaft 790 can, for example, include two bar ends as shown in Figure 29. This is applicable to many other examples herein, while it is understood that the shaft 790 (or the elongated blocking structure 701, or the like) represents those parts of the elongated arrangement 600 that contribute to the function of the biasing structure and / or the blocking structure. In more detail, in some examples, the cross-section of the shaft 790 can include a primary portion 795 and a secondary projection 796 (e.g. extending away from the center of the cross-section of the shaft 790).

[0846] In general, a counterweight 929 can be used in combination with the biasing structure. In one example, as shown in Figure 36, the counterweight 929 is provided to counter a rotational moment that occurs due to the solar panel 400 being arranged at an angle (as seen in the yz-plane) relative to the secondary projection 796. Thereby, the secondary projection 796 and the counterweight 929 are arranged to hold the solar panel at the predefined angle, which is located at the middle of the biasing interval.

[0847] In general, it may be preferred that the predefined rotation angle (set by the biasing structure 800) is at the center of the bias interval.

[0848] According to another example, as shown in Figure 37, the biasing structure can be realized by the suspension part 771 comprising the shaft 790 (optionally including its features as described herein). Further, the biasing structure can be realized by the solar panel part 772 comprising the aperture 780 (optionally including its features as described herein). As indicated by the dashed line in Figure 37, the solar panel part 772 can have an opening. In this manner, the amount of material required is reduced and / or access (e.g. for maintenance) to the interior of the solar panel part 772 is provided.

[0849] In general, it can be sufficient that only one section (e.g. along the extension direction of the elongated arrangement 600) is configured with the cross-sectional shapes of the aperture 780 and the cooperating shaft 790 as described herein. To reduce wear and tear, it may be preferred that there are at least two such sections (e.g. one at each end of the elongated arrangement 600), but not necessarily. This means that the shape of the cross-section (e.g. of the aperture 780 and / or the shaft 790 and / or the like) does not have to be constant along the x-axis as shown in the Figures, but it can vary.

[0850] Figure 38 and Figure 39 illustrate examples of the cross-section of the suspension part 771 and the solar panel part 772, respectively. In some examples, these figures illustrate examples of the crosssection of the solar panel part 772 and the suspension part 771 (as illustrated in Figure 37).

[0851] Figure 38 shows, for example, that the inner diameter of the suspension part 771 can be greater than the outer diameter (x) of the solar panel part 772. In this manner, the solar panel part 772 can be allowed to rotate with respect to the suspension part 771. The inner diameter is matched to the outer diameter (e.g. set to the outer diameter x plus a margin). The smaller the margin, the greater the force required to rotate (i.e. stronger wind). The same or similar reasoning applies to the example of Figure 37, where Figures 38 and 39 then illustrate examples of the cross-section of the solar panel part 772 and the suspension part 771.

[0852] In the following, the cross-section formed by the inner or outer surfaces of the suspension part 771 and / or the solar panel part 772 can be described as a union of two circles with different radii that are connected by tangent lines on opposite sides of a central line through the centers of the two circles. The central line can be vertical.

[0853] For example, referring to Figure 38, d2 can be 30% to 90% of dl.

[0854] With the exemplifying cross-section shown in Figures 38 and 39, the shape implies that the shaft 790 can find the lowest position in the holding element 780 (e.g. even when a symmetric central line of the cross-section of the holding element is tilted, e.g. up to 30°), such that resistance (e.g. in terms of torque) gradually decreases toward the start and end of the bias interval.

[0855] In another example, shown in Figure 40, the shape can be formed similarly to that in Figures 31 to 37, wherein the transition from the primary part 788 to the secondary part 789 is smooth and / or the transition from the primary portion 795 to the secondary projection 796 is smooth.

[0856] Figure 42 and Figure 43 illustrate that any one of the examples herein can include an additional secondary part 789b and / or an additional secondary projection 796b.

[0857] Figure 44 shows another example of the biasing structure (in terms of the cross-sectional shapes of the suspension part 771 and the solar panel part 772). In some examples, either the suspension part 771 or the solar panel part 772 can enclose the other (as seen in the cross-section in the yz-plane). In Figure 44, solar panels 400 are provided at the outer solar panel part 772. In this context, it is noted that with the examples of the biasing structure 800, the shape can be inverted (i.e. turned upside down) if desired, for example, to view an embodiment with the solar panel part 772 as the inner part or as the outer part (cf. Figures 31 and 37).

[0858] According to Figure 44, the suspension part 771 can have a circular cross-section as the primary part 788 with an indentation as the secondary part 789. The indentation is configured to extend from the circle forming the primary part toward the center of the circle. The solar panel part 772 can have a circular cross-section as the primary portion 795 and a secondary projection 796 formed between two depressions 796d. The two depressions extend outside the circle forming the primary portion, whereby the secondary projection 796 is formed between them. The secondary projection 796 extends to the circle forming the primary portion 795 (e.g. from outside the circle). The indentation can be configured to receive the secondary projection 796. The circular part of the primary portion 795 can have a diameter that corresponds to (e.g. is equal to, possibly with some margin) the diameter of the circular part of the primary part 788. Figure 44 illustrates an example of the inverted embodiments. Based on Figure 44, a corresponding non-inverted embodiment can be realized when the solar panels are attached to the shaft and the cross-sections are turned upside down relative to the illustration in Figure 44.

[0859] Figure 45 to Figure 47 illustrate an example in which the biasing structure 800 is implemented by a shaft 790 and a holding element 770. The cross-section of the shaft 790 can be similar or the same as that described in Figures 38 and 39. In addition, at least a portion 775 of the inner surface 787 is elastically flexible. This portion can be made of a flexible material. These examples can also be implemented as inverted embodiments by viewing the Figures upside down and considering the shaft 790 as an example of the suspension part 771 and the holding element as an example of the solar panel part 772.

[0860] Figure 45 illustrates that at least a portion 775 of the surface can be made flexible by providing the surface with two spring blades (or the like).

[0861] Figure 46 illustrates that at least a portion of the surface can be elastically and flexibly pushed away to allow the shaft 790 to rotate.

[0862] Figure 47 illustrates that the shaft 790 is located at the predefined rotation angle and is optionally forced to that position by the two spring blades (or the flexible material of the surface). As seen in Figure 47, at least a portion of the inner surface 787 can be biased toward a shape that further reduces (compared to, e.g., Figure 39) and creates a tapered section of the cross-section. In Figure 46, it is shown that the shaft 790 is about to leave the tapered section and rotate freely (e.g. at least with respect to the elastically flexible inner surface 787 that is biased toward a tapered shape). When the shaft 790 rotates freely, the solar panel part 772 is outside the bias interval.

[0863] In another example, shown in Figure 48, the biasing structure 800 is realized by a magnet 801 and a magnetic material 802. The magnet 801 can be provided at or in the suspension part 771 and the magnetic material 802 can be provided at or in the solar panel part 772. Alternatively, the magnetic material 802 can be provided at or in the suspension part 771 and the magnet 801 at or in the solar panel part 772. In this example, the suspension part 771 (e.g. the plate 770) is configured to receive the shaft 790. However, in other examples (similarly to Figure 37), the solar panel part 772 can be configured to receive the suspension part 771.

[0864] When the suspension part 771 is realized by the plate 770 of the elongated arrangement 600, the plate 770 can be arranged for suspension of the elongated arrangement 600 at one of the two suspension points 110. Further, the plate 770 can include (or be provided with) the magnet 801 or the magnetic material 802. An end of the elongated arrangement 600 (e.g. a bar end) can be configured to be receivable by the plate 770. Then, the bar end can include (or be provided with) the magnet 801 or the magnetic material 802.

[0865] In the example of Figure 48, the magnet 801 and / or the magnetic material 802 can be located at a lower part of the suspension and / or solar panel part 771, 772 (e.g. as seen with respect to the inner and / or outer cross-sections). In this manner, the biasing provided by the magnet 801 and the magnetic material 802 is achieved. In some examples, the magnet 801 and / or the magnetic material 802 can be located at an upper part of the suspension and / or solar panel part 771, 772 (e.g. as seen with respect to the inner and / or outer cross-sections).

[0866] It may be preferred that the magnet 801 and the magnetic material 802 are located centrally (e.g. along a vertical center line of the cross-sections of the suspension and / or solar panel part 771, 772) so that any weight of the magnet or magnetic material contributes symmetrically toward or against the biasing provided by the magnetic attraction between them.

[0867] In some examples, the magnetic material 802 can be a further magnet. Then, the magnet 801 can be a first magnet and the further magnet a second magnet, where the first and second magnets are separate. The first and second magnets are thus not the same and can be configured to attract each other (e.g. by arranging opposing poles to bring the solar panels toward the predefined rotation angle).

[0868] Figure 49 to Figure 52 show examples in which the biasing structure 800 is realized by a flexible blade 804 arranged to hold the elongated arrangement 600 at the predefined angle by abutting a surface 803 in a cut-out in a bar end of the elongated arrangement 600. The bar end can refer to any of the terminal ends of the elongated arrangement 600 (e.g. either terminal end of the shaft). The flexible blade 804 can be made of any flexible material (such as metal, plastic, fiberglass, or the like) and can take the form of a leaf spring, a flexible elongated quadrangular sheet, a single- or multilayered leaf spring, a blade spring, or the like.

[0869] Figure 50 shows (by a dashed line) that a part of the aperture can be larger to accommodate the flexible blade 804.

[0870] A cross-section of the bar end (e.g. in the yz-plane) can have the shape of a circular segment, wherein a chord of the circular segment runs in the surface 803.

[0871] The circular segment can have a central angle of 180° or more. The circular shape of the segment abuts the flexible blade 804 when the solar panels are rotated to positions outside the bias interval. In some examples, the cut-out can have a cross-sectional chord that is formed as an arc instead of a line. The arc can then have a radius that is greater than (e.g. 5, 10, or 20 times greater than) the radius of the circle depicting the cross-section of the bar end.

[0872] Figure 53 to Figure 56 show further examples of how to implement the biasing structure 800 by configuring the cross-sections of the suspension part 771 and the solar panel part 772. According to Figure 53, the inner surface 789 of the suspension part 771 is configured to receive the solar panel part 772 and allow it to rotate within the inner surface 789 (e.g. limiting movement along the z-axis but allowing some movement along the y-axis so that the solar panel part 772 can leave the bias interval and / or the predefined rotation angle).

[0873] As shown in Figure 53, the suspension part 771 can include a tap 820 (e.g. a projection or protruding element) that is received into a hole 821 (e.g. a groove or cavity) in the solar panel part 772. The hole 821 can emerge at the curved surface of the solar panel part 772, which can have a circular crosssection (e.g. in the yz-plane). The tap 820 can be made of a flexible or form-stable material (e.g. plastic, composite, metal, rubber, or the like) and is an example of the elongated element 805.

[0874] Figure 54 illustrates that the tap 820 can abut and slide along the outer perimeter of the solar panel part 772 when the solar panel has left the predefined angle and bias interval.

[0875] Figure 55 illustrates that it may be beneficial to mount the tap 820 at a position translated along the x- axis and spaced away from a portion of the suspension part 771 that prevents movement of the solar panel part 772 along the z-axis. In this manner, the tap 820 can be easily accessed and replaced when worn. When the tap 820 is worn, it may result in a reduced wind force required for the solar panel to leave the predefined rotation angle and / or the bias interval compared to when the tap 820 is new. This can be beneficial if the tap 820 is made of a softer material that is more likely to wear than the material of the solar panel part 772. The tap 820 can be attached with no more than two screws for fast and simple replacement. Additionally, the tap 820 material can be softer than the material of the solar panel part 772, thereby causing less wear on the solar panel part 772. Figure 56 (A through H) shows a few examples of the cross-section of the tap 820 and the solar panel part 772. The solar panel part 772 can have a hole that forms a wedge (A, B), a rectangle (C), a rectangle with beveled walls (D), etc., in its cross-section (e.g. of the shaft or the like). In example D, a larger torque is initially required to counteract gravity, then less torque is needed when the part of the wall with a lesser angle is reached, and finally - as with all examples in Figure 56 - no biasing is provided when the circular part of the cross-section abuts the tap 820.

[0876] The tap 820 of the suspension part 771 can thus have a cross-sectional shape in the form of a wedge (E, F), a rectangle with a concave circular roof (G), a rectangle (H), or the like.

[0877] In a further example, as shown in Figures 57 to 62, the biasing structure 800 is implemented by having the suspension part 771 comprise an elongated element 805 realized as a spring plunger 806. The spring plunger 806 is arranged to hold the elongated arrangement 600 at the predefined angle by being received into an excavation 807 in a bar end of the elongated arrangement 600 (e.g. the shaft 790). The spring plunger 806 can be biased by a spring 808.

[0878] The excavation 807 can be a cylindrical hole. It is preferred that the spring plunger 806 does not extend too far into the solar panel part 772. In some examples, if the spring plunger 806 is provided with a ball (not shown) at the end extending into the hole, the depth of the cylindrical hole can be less than half the diameter of the ball. However, the spring plunger 806 can also be positioned (e.g. vertically) to ensure that the solar panel part 772 can disengage from the spring plunger 806 when the solar panel is subjected to sufficiently strong wind (e.g. above a threshold). In this manner, the spring plunger 806 forces the solar panel back to the predefined rotation angle within the bias interval.

[0879] Figures 61 and 62 illustrate that the excavation 807 can have a conical shape (e.g. with the base of the conical shape emerging at the outer surface of the solar panel part 772). In this manner, the elongated element 805 can be realized as a plunger that is only biased toward the solar panel part 772 by gravity. Thanks to an opening at the base of the conical shape, the plunger can align with the tip of the conical shape. The excavation 807 can have any other suitable tapered shape to assist the elongated element 805 in returning the solar panel to the predefined rotation angle. The elongated element 805 is not shown in Figures 61 and 62 for simplicity.

[0880] Figures 63 to 65 illustrate that the elongated element 805 can be implemented as a blade 809. In other examples, the elongated element 805 can be implemented as a rod, sheet, pin, plug, or the like. As in the examples above, the blade 809 can be biased (e.g. mechanically, magnetically, or by gravity) toward the solar panel part 772.

[0881] Figure 64 illustrates that a wedge shape is formed in the solar panel part 772. This means that at least a portion of the cross-section (e.g. in the yz-plane) of the solar panel part 772 (such as the bar end) can have the shape of a circular sector (e.g. with a central angle a of 200°, 250°, 300°, or another suitable angle). However, in some examples, the cross-section of the solar panel part 772 can have the shape of a circle with a cut-out wedge, where the tip of the wedge does not necessarily coincide with the center of the circle as is the case when the cross-section resembles a circular sector.

[0882] Figure 65 is provided to illustrate that a coordinate system aligned with the system 100 (the elongated arrangement 600, etc.) can be rotated, tilted, and / or translated with respect to a global coordinate system (not shown) having a horizontal xz-plane, a vertical yz-plane, and a vertical yx-plane (with the vertical yz-plane and the vertical yx-plane being orthogonal).

[0883] In the examples of Figures 49 to 65, the suspension part 771 of the elongated arrangement 600 can be implemented as an integral part of the beam 105, if desired.

[0888] - Example of Figure 17A combined with the example of Figure 13 A,

[0889] - and more.

[0890] Even though embodiments of the various aspects are described in the present disclosure, many different alterations, modifications, and the like will become apparent to those skilled in the art. The described embodiments are therefore not intended to limit the scope of the present disclosure.

[0891] Certain embodiments of the present invention will now be described with reference to Figures 66 to 76.

[0892] Figure 66 shows a perspective overview of the solar panel system 100 with its various components. The solar panel system 100 includes a solar panel 20, a motor 40 with a coupler 45, a biasing structure 30, and a mounting frame 10. The solar panel 20 is designed to capture solar energy and convert it into electricity. The motor 40 drives the biasing structure 30 using the coupler 45 to alter the orientation of the solar panel 20. The mounting frame 10 supports the solar panel 20, motor 40, and biasing structure 30.

[0893] Figure 67 shows a detailed view of the solar panel 20 and its axis of rotation. The solar panel 20 is rotatable by a rotation member 75, which allows the solar panel 20 to rotate a full 360 degrees around the rotation member 75.

[0894] Figure 68 shows a perspective overview where the biasing structure 30 is built into the motor 40. This integration allows for direct force transmission to the solar panel 20 and simplifies the overall system. Figure 69 shows a perspective overview where a part of the biasing structure 30 is built into the rotation member 75. This configuration allows the biasing structure 30 to directly interact with the rotation member 75 and influence the rotation of the solar panel 20.

[0895] Figure 70 shows a view of the motor 40 and coupler 45, where part of the coupler 45 is a cable system connected to several biasing structure 30. This configuration allows a single motor 40 to drive multiple solar panels 20 via the biasing structure 30 using row rotation member 175.

[0896] Figure 71 shows a view of the motor 40 and coupler 45, where part of the coupler 45 is a coupling rod connected to several rotation members 75 with built-in biasing structure 30. This configuration also allows a single motor 40 to drive multiple solar panels 20.

[0897] Figure 72 shows a view of the motor 40 and coupler 45, where part of the coupler 45 is a loop of cables connected to row rotation member 175, which are in turn connected to biasing structure 30 via additional cable loops. This configuration allows for flexible and unrestricted movement of the solar panels 20.

[0898] Figure 73 shows a detailed view of the rotation member 75, where part of the rotation member 75 is placed under each panel that is to be rotated. This configuration provides support and stability to the solar panels 20 during rotation.

[0899] Figure 74 shows a detailed view of the rotation member 75, where part of the rotation member 75 is clamped around each side of each panel that is to be rotated. This configuration ensures a secure connection between the solar panels 20 and the rotation member 75.

[0900] Figure 75 shows a close-up view of the biasing structure 30. The biasing structure 30 mechanically influences the rotation of the solar panel 20 and is configured to mechanically disengage the solar panel 20 from the coupler 45 when external force upon the solar panel 20 exceeds an external force threshold.

[0901] Figure 76 shows a perspective view of the solar panel array 2000, displaying the arrangement of multiple solar panels 20. The solar panel array 2000 comprises between four and a hundred solar panels 20, arranged in two or more rows and columns. A single motor 40 is used to rotate all the solar panels 20 in the solar panel array 2000, reducing overall system cost and complexity.

[0902] The solar panel system 100 is designed to optimize the capture of solar energy by adjusting the orientation of the solar panels 20 in response to varying environmental conditions. The system 100 includes several components that work together to achieve this goal, including the solar panels 20 themselves, a motor 40, a biasing structure 30, and a control unit 50. The system 100 is designed to withstand a range of weather conditions, from calm sunny days to high wind and heavy snow conditions. The system 100 is also designed to be scalable, allowing for the addition of more solar panels 20 to increase the overall power generation capacity of the system 100. In some examples, the solar panel 20 is a component of the solar panel system 100. The solar panel 20 is designed to capture solar energy and convert it into electricity. The size of the solar panel 20 can vary, but in some implementations, it may range from 1.6m x 0.9m to 2.5m x 1.4m. The weight of the solar panel 20 can also vary, but in some examples, it may be between 10-40 kg. Lighter panels, weighing between 2kg - 10kg, may also be used in some configurations, however the present invention will function adequately with panels of any size The use of lighter panels can reduce the torque related to gravity, allowing for the use of smaller motors 40. The solar panel 20 is subject to external forces from weather conditions, such as the force of wind, the weight of snow or ice, the force of rain and hail, the force of gravity, and the force of seismic activity.

[0903] In some implementations, the solar panel 20 is rotated by a rotation member 75. The rotation member 75 allows the solar panel 20 to rotate around a rotation member 75, which is connected to the mounting frame 10. The rotation member 75 enables the solar panel 20 to rotate a full 360 degrees, allowing it to capture solar energy from any direction. The rotation member 75 is also designed to work in conjunction with the biasing structure 30 and the motor 40 to control the rotation of the solar panel 20. The rotation member 75 can be made from a variety of materials, but in some examples, it may be made from a durable and weather-resistant material such as stainless steel or a high-strength plastic.

[0904] The motor 40 is responsible for driving the biasing structure 30, which in turn influences the rotation of the solar panel 20. In some examples, the motor 40 may have a torque of less than 200 Nm per solar panel 20 driven by the motor 40. This is possible due to the reduced torque requirements resulting from the use of the biasing structure 30, which allows the motor 40 to control the angle of the solar panel 20 even during high winds. The motor 40 may have a power output of between 100-200 watts and operate at a voltage of between 12-48 volts. The size of the motor 40 can vary, but in some examples, it may be between 100-300 mm in length, 50-150 mm in width, and 50-150 mm in height. The weight of the motor 40 can also vary, but in some examples, it may be between 1-5 kg.

[0905] In some configurations, the motor 40 is connected to at least one coupler 45. The coupler 45 is a component that connects the motor 40 to the biasing structure 30 of each solar panel 20 via connection to a row rotation member 175. The row rotation member 175 may cause a row of inter-connected solar panels 20 to rotate, as shown in Figures 70 and 71. The coupler 45 is designed to transmit the rotational force generated by the motor 40 to the row rotation member 175, which in turn influences the rotation of the solar panel 20. The coupler 45 can take various forms, including a coupling rod, a gear coupling, or a cable system. In some examples, a cable system can connect a single motor 40 to the biasing structure 30 of multiple solar panels 20. The cable system is designed to spin without being 'twirled', and in some examples, it may have a diameter of 1-5 mm and a length of 2-8 meters between each coupler 45 in an array of solar panels 20. The use of a cable system with thin wires (i.e. 5mm or less) can reduce the risk of shading on the solar panel 20, which can otherwise lead to a significant reduction in solar energy production.

[0906] In some examples, the motor 40 is equipped with a gearbox. The gearbox is a mechanical device that provides the necessary speed reduction to increase the torque output of the motor 40. The gearbox is integrated into the motor 40 and works in conjunction with the coupler 45 and the biasing structure 30 to control the rotation of the solar panel 20.

[0907] In some configurations, the motor 40 is housed within a motor housing 48. The motor housing 48 is designed to protect the motor 40 from the environment, including weather conditions such as rain, snow, and high winds, as well as dust and debris. The motor housing 48 can be made from a variety of materials, but in some examples, it may be made from a durable and weather-resistant material such as stainless steel or a high-strength plastic. The motor housing 48 is designed to withstand the external forces that the solar panel 20 is subject to, such as wind and snow loads. The motor housing 48 may also include features to facilitate the maintenance and repair of the motor 40, such as access panels or removable sections.

[0908] The biasing structure 30 influences the rotation of the solar panel 20. It functions by exerting a controlled force upon the solar panel 20 via the rotation member 75, both to initiate and maintain its rotation. This allows the solar panel 20’s orientation to be controlled within a specified angular range, ensuring optimal exposure to sunlight. More than one solar panel 20 can be connected to a single biasing structure 30. The force applied by the biasing structure 30 can also counter external forces such as wind, maintaining the stability of the solar panel 20 at a predefined angle, effectively resisting motion beyond this set parameter.

[0909] The biasing structure 30 has a special function when faced with exceptionally high external forces: it is capable of mechanically disengaging the solar panel 20 from the motor 40. This disengagement functionality permits the solar panel 20 to freely rotate, independent of the motor's influence, a crucial feature during extreme weather events. This disengagement is triggered when forces acting on the solar panel 20 surpass the specified external force threshold, which is reliant on various factors including the present angle of the solar panel 20. Once the external force diminishes, falling below the threshold, the biasing structure 30 is designed to automatically re-engage, reasserting control over the solar panel 20’s rotation.

[0910] The external force threshold is a crucial specification of the biasing structure 30, calibrated based on real-time conditions. For instance, the threshold could correspond to an external force resulting from a snow load in excess of 10 cm or wind speeds greater than 10 meters per second, or a combination of more than one force where the individual force from each source is lower than if that force was present on its own. This dynamic threshold caters to minimizing the complexity and financial outlay of the solar panel system 100 by negating the necessity for a robust motor 40 capable of enduring high wind forces.

[0911] By automatically disengaging and re-engaging based on weather conditions, it ensures uninterrupted operation and longevity of the system. It allows for cost-effectiveness by enabling the use of a single high-torque motor 40 to control the rotation of several solar panels 20, hence diminishing the overall expense incurred by the system. Additionally, it mitigates the risk of damage during high wind events by facilitating an independent rotation of solar panels, thereby minimizing the strain on both the panels and the motor 40.

[0912] The biasing of the solar panels 20 via a biasing structure 30 can be achieved by mechanical bias, e.g. using springs, or the like. The biasing can, also or alternatively, be achieved by one or more magnetic fields, generated by a magnet, such a permanent magnet, an electromagnet, or the like. Still further, the biasing can, also or alternatively, be achieved by that the solar panels are subjected to gravity, e.g. as a dominating biasing factor.

[0913] Figure 75 demonstrates one example of a biasing structure 30 comprising a shaft 790. Here the solar panel 20 is illustrated by numeral 772 and comprises an aperture 780, having a cross section designed to accommodate a member 771 of similar cross section. The diameter of the member 771 is less than the diameter of the aperture 780, allowing the member 771 to be inserted in the aperture and rotate relative thereto. When fully engaged in the aperture 780, the member 771 and solar panel 20 will rotate together. As indicated by the dashed line in Figure 38, the solar panel 20 part 772 can have an opening. In this manner, reducing the amount of material required and / or providing access, e.g. for maintenance purposes, to the interior of the solar panel 20 part 772.

[0914] In some configurations, the biasing structure 30 is designed to mechanically disengage the solar panel 20 from the motor 40 when an external force upon the solar panel 20 exceeds an external force threshold. This mechanical disengagement is achieved via the biasing structure 30 and is achieved without electricity, as the biasing structure 30 as previously described operates via mechanical bias, magnetic means, or gravity. The external force threshold is a predetermined value that represents the maximum force that the biasing structure 30 can withstand before it disengages from the motor 40. The external force threshold can depend on various factors, including the current angle of the solar panel 20, the wind speed, and the wind direction. In some examples, the external force threshold may correspond to forces resulting from a snow load of above 10 cm or a wind speed above 10 meters per second. The external force threshold may also in part be reached due to gravity, the effects of which may vary based on the present angle of the solar panel 20. The external force threshold is designed to protect the solar panel 20 and the motor 40 from damage due to excessive forces, such as those caused by high winds or heavy snow loads. When the external force upon the solar panel 20 exceeds the external force threshold, the biasing structure 30 disengages, allowing the solar panel 20 to rotate freely and reduce the risk of damage. Once the external force subsides, the biasing structure 30 may re-engage to control the rotation of the solar panel 20. This re-engagement may depend on various factors such as the preferred angle of the solar panel 20.

[0915] Further details of the control unit 50 will now be provided.

[0916] The control unit 50 may be responsible for controlling the motor 40 to rotate the solar panel 20 to a desired rotation angle. The control unit 50 may calculate the desired rotation angle based on various input data, including the position of the sun, the wind speed, the wind direction, and the external force threshold of the biasing structure 30. The control unit 50 is designed to optimize the power generation of the solar panel 20 by adjusting its orientation to capture the maximum amount of solar energy, while also ensuring that the external force threshold is not exceeded under high wind conditions. The control unit 50 can be programmed with an algorithm that takes into account these various factors to calculate the desired rotation angle. In some examples, the control unit 50 may also incorporate weather forecast data to predict potential adverse conditions and preemptively adjust the rotation angle of the solar panels 20.

[0917] In some configurations, the control unit 50 receives input data that is used to calculate the desired rotation angle of the solar panel 20. The input data may include information about the wind speed, the wind direction, the rotation of the solar panel 20, the position of the sun and the current date and time. The input data may be provided by various sources, such as sensors installed on the solar panel system 100, or from an external source, such as a remote server. The control unit 50 uses this input data to calculate the desired rotation angle that will optimize the power generation of the solar panel 20, while also ensuring that the external force threshold of the biasing structure 30 is not exceeded under high wind conditions.

[0918] In some implementations, the wind speed is a piece of input data that the control unit 50 uses to calculate the desired rotation angle of the solar panel 20. The wind speed can significantly affect the orientation of the solar panel 20, as high wind speeds can exert a large force on the solar panel 20 and potentially cause it to rotate beyond the desired angle. The wind speed can be measured by an anemometer, or similar device capable of measuring wind speed installed on the solar panel system 100, or it can be provided by an external source, such as a weather station or a remote server. The control unit 50 uses the wind speed data to adjust the desired rotation angle of the solar panel 20 to ensure that the external force threshold of the biasing structure 30 is not exceeded under high wind conditions.

[0919] In some examples, the wind direction is another piece of input data that the control unit 50 uses to calculate the desired rotation angle of the solar panel 20. The wind direction can affect the orientation of the solar panel 20, as winds coming from different directions can exert different forces on the solar panel 20. The wind direction can be measured by a wind vane, or similar device capable of measuring wind direction installed on the solar panel system 100, or it can be provided by an external source, such as a weather station or a remote server. The control unit 50 uses the wind direction data to adjust the desired rotation angle of the solar panel 20 to ensure that the external force threshold of the biasing structure 30 is not exceeded under high wind conditions.

[0920] In some configurations, the current rotation of the solar panel 20 is a piece of input data that the control unit 50 uses to calculate the desired rotation angle of the solar panel 20. The current rotation of the solar panel 20 can be measured by a rotation sensor installed on the solar panel 20 or the rotation member 75 or installed in some other location close enough to the solar panels to be able to monitor them. The rotation sensor can provide real-time data on the current rotation of the solar panel 20, which the control unit 50 can use to calculate the desired rotation angle. The control unit 50 uses the current rotation data to adjust the desired rotation angle of the solar panel 20 to ensure that the external force threshold of the biasing structure 30 is not exceeded under high wind conditions.

[0921] In some implementations, the position of the sun is a piece of input data that the control unit 50 uses to calculate the desired rotation angle of the solar panel 20. The position of the sun can significantly affect the amount of solar energy that the solar panel 20 can capture. The sun position can be determined by a sun tracker installed on the solar panel system 100, or it can be provided by an external source, such as a remote server. The control unit 50 uses the sun position data to adjust the desired rotation angle of the solar panel 20 to optimize the capture of solar energy, while also ensuring that the external force threshold of the biasing structure 30 is not exceeded under high wind conditions. The sun position may be derived from the current date and time given the geographic location of the solar panel system 100..

[0922] In some examples, the solar panel system 100 includes an anemometer for measuring the wind speed on the solar panel 20. The anemometer provides real-time data on the wind speed, which the control unit 50 uses to calculate the desired rotation angle of the solar panel 20.

[0923] In some configurations, the solar panel system 100 includes a receiver for receiving input data from an external source. The receiver can receive data on various factors, such as the wind speed, the wind direction, the rotation of the solar panel 20, and the position of the sun. The receiver is designed to communicate with the external source, such as a remote server, to receive the input data.

[0924] In some configurations, the solar panel system 100 includes a determining unit 60 for identifying if one or more solar panels 20 are out of synch with the other panels in the solar panel system 100. In some implementations, the determining unit 60 can identify if one or more solar panels 20 are not at the desired rotation angle by comparing the actual energy generated by a row of solar panels 20 to the energy generated by another row of solar panels in the solar panel system 100 or to an expected energy generation amount. In some implementations, the determining unit 60 includes a sensor for providing information to the determining unit 60. The sensor can be a camera, an angular embedder, or a counter. The camera can capture images of the solar panel array 2000 and use image recognition software to identify if one or more solar panels 20 are not aligned with the others. The angular embedder can measure the angle of rotation of each solar panel 20 and provide this information to the determining unit 60. The counter can count the number of rotations of each solar panel 20 and provide this information to the determining unit 60.

[0925] In some examples, the solar panel system 100 includes a mounting frame 10. The mounting frame 10 supports the solar panel 20, the motor 40, and the biasing structure 30. The mounting frame 10 is designed to withstand a range of weather conditions, from calm sunny days to high wind and heavy snow conditions. The mounting frame 10 can be made from a variety of materials, but in some examples, it may be made from a durable and weather-resistant material such as stainless steel or a high-strength plastic.

[0926] In some configurations, the solar panel 20 is connected to the mounting frame 10 via a rotation member 75. The rotation member 75 allows the solar panel 20 to rotate relative to the mounting frame 10. The rotation member 75 can take various forms, including a rotatable rod, a rotating bearing, rotatable solar panel clamps, a swivel mount, a ball joint, a pivot arm, a rotating shaft, and an articulated linkage. The rotation member 75 is designed to withstand the external forces that the solar panel 20 is subject to, such as wind and snow loads. The rotation member 75 can be made from a variety of materials, but in some examples, it may be made from a durable and weather-resistant material such as stainless steel or a high-strength plastic.

[0927] In some implementations, the mounting frame 10 includes a ground securing mechanism 12. The ground securing mechanism 12 secures the mounting frame 10 to the ground to provide stability and support for the solar panel system 100. The ground securing mechanism 12 can take various forms, including a concrete base with anchor bolts, ground screws, concrete ballasts, ground anchors, a pier foundation, a pile foundation, and a tilt-up concrete footing. The ground securing mechanism 12 is designed to withstand a range of weather conditions, from calm sunny days to high wind and heavy snow conditions. The ground securing mechanism 12 can be made from a variety of materials, but in some examples, it may be made from a durable and weather-resistant material such as stainless steel or a high-strength plastic.

[0928] In some examples, the solar panel system 100 includes a solar panel array 2000. The solar panel array 2000 comprises multiple solar panels 20 arranged in rows and / or columns. The number of solar panels 20 in the array can vary, but in some implementations, it may range from 40 to 200. The solar panel array 2000 is designed to maximize the capture of solar energy by providing a large surface area for sunlight exposure. The solar panel array 2000 is also designed to be scalable, allowing for the addition of more solar panels 20 to increase the overall power generation capacity of the system 100. In some configurations, a single motor 40 is used to rotate all the solar panels 20 in the solar panel array 2000. This is achieved by connecting the motor 40 to the biasing structure 30 of a row of solar panels 20 via a coupler 45. This design reduces the overall cost and complexity of the solar panel system 100 by requiring only a single motor 40 to control the rotation of multiple solar panels 20.

[0929] The operation of the solar panel system 100 will now be described. The operation of the solar panel system 100 involves several steps that are designed to optimize the capture of solar energy while also ensuring the stability and durability of the system 100 under a range of weather conditions. The following operation provides an example implementation.

[0930] The control unit 50 calculates the desired rotation angle of the solar panel 20 based on various input data, including the position of the sun, the wind speed, the wind direction, and the external force threshold of the biasing structure 30. The desired rotation angle is influenced by several factors. The position of the sun is a factor, as the solar panel 20 should be oriented towards the sun to maximize the capture of solar energy. The wind speed and wind direction are also factors, as high wind speeds can exert a large force on the solar panel 20 and potentially cause it to rotate beyond the desired angle. The external force threshold of the biasing structure 30 is another factor considered in the calculation of the desired rotation angle. Under low wind conditions, for example 0-5 m / s, the external force threshold should not be considered, however under intermediate conditions, for example 5-15 m / s then the solar panel 20 should not be rotated to an angle which would cause disengagement of the biasing structure 30. Depending on factors such as wind direction, the angle at which this disengagement may occur will vary.

[0931] The control unit 50 controls the motor 40 to rotate the solar panel 20 to the desired rotation angle. The control unit 50 sends a control signal to the motor 40, which in some instances drives the biasing structure 30 to rotate the solar panel 20.

[0932] The biasing structure 30 plays a role in controlling the orientation of the solar panel 20. The biasing structure 30 mechanically influences the rotation of the solar panel 20 by applying a force that initiates and maintains the rotation of the solar panel 20. The biasing structure 30 w...
