Description

[0001] The invention relates to a solar module holder, a solar power plant and a method for adjusting a position of a solar module arranged in a solar power plant.

[0002] Solar systems, also known as solar power plants or solar energy power plants, are generally designed to generate electrical energy from solar energy (photovoltaic systems) or thermal energy from solar energy, particularly hot water (solar thermal energy). Photovoltaic systems will be discussed in particular below.

[0003] Solar systems typically include at least a mounting frame, one or more solar modules, an inverter, cables, and / or an electricity meter. The mounting frame serves to securely install the solar modules at a location and ideally ensures good ventilation for the solar module(s).

[0004] Known solar modules essentially consist of at least one solar cell, in particular a plurality of solar cells, which can be designed, for example, as monocrystalline solar cells, polycrystalline solar cells, thin-film cells or organic solar cells.

[0005] The electrical energy generated by the at least one solar cell is transported via electrical cables to an inverter, which converts the generated direct current into alternating current. Finally, the generated electricity can be used on-site and / or fed into a power grid.

[0006] In recent years, photovoltaic systems have increasingly been used in the private sector and the electrical energy generated is used in particular to operate electrical appliances in the respective private household.

[0007] The output of a solar power plant, also known as the energy yield, depends primarily on the type of solar cell and the number of solar cells and solar modules, as well as the solar energy applied to the solar module(s). In addition to the intensity and duration of solar radiation, the applied solar energy depends particularly on the horizontal and vertical angle of incidence of the sun's rays.

[0008] For maximum energy generation, it is well known among experts that the horizontal component of the angle between the sun's rays hitting the solar panel and the solar module should ideally be between 5° and 60°, particularly between 15° and 45°, and the vertical component between -80° and +80°. The angle of solar radiation varies, particularly depending on the season and time of day.

[0009] Tracking systems are known for adjusting the optimal orientation of a solar module in relation to the sun.

[0010] Known tracking systems usually have a base, also called a central axis or mast, on which the solar module is mounted in a rotatable manner. Tracking systems are also known that feature a solar module guided on a rail system.

[0011] Known tracking systems usually feature motors, which are used to drive actuators to move the solar module's position along the three translational and rotational spatial axes. This movement is often implemented using a control unit.

[0012] A distinction is made between astronomical and sensor-based tracking. With astronomical tracking, the tracking is primarily based on the fixed star, the sun. With sensor-based tracking, a sensor is installed on the tracking system or connected to it via IT. This sensor detects the brightest point of light in the sky and transmits it as a signal to the control device, which is configured to guide the solar module based on the detected brightest point of light.

[0013] In addition, solar power plants are known that incorporate additional sensors, particularly anemometers. Taking into account the current wind speed, the control system can be further configured to move the solar module to an optimal position so that it is protected during high wind speeds.

[0014] The known state of the art has the disadvantage that the solar modules are exposed to wind load even in an optimized positioning at high wind speeds because they are arranged on the masts or rail systems.

[0015] The object of the invention is to improve the state of the art.

[0016] The object is achieved by a solar module holder, comprising a first frame element and a second frame element arranged on the first frame element by means of an adjustable connecting element, wherein the first frame element is designed to receive a solar module and an angle between the first frame element and the second frame element can be automatically adjusted by means of the adjustable connecting means, wherein the first frame element rests on the second frame element oriented substantially parallel to the second frame element at a first set angle and the first frame element is at least partially lifted off from the second frame element at a second set angle.

[0017] Advantageously, the solar module holder according to the invention allows for an optimal angle of the solar module held by the first frame element relative to the sun. Furthermore, the solar module, which is held in particular by the first frame element, can be moved into an optimal and secure position in strong winds using the solar module holder according to the invention. The first frame element rests in particular on the second frame element, so that the smallest possible surface area exposed to wind is created, and the solar module is thus essentially protected by the solar module holder.

[0018] An essential idea of ​​the invention is based in particular on providing a holder for a solar module which realizes an optimal angle of solar radiation onto the solar module and transfers the solar module into a safe position in the event of high wind loads.

[0019] The following terminology is explained:

[0020] A "solar module mount" is understood, in particular, to be a frame designed for arranging a solar module at an installation location. The installation location can be essentially horizontal, vertical, and / or at an angle. To arrange the solar module mount at an installation location, the solar module mount can be equipped with weighting elements. Additionally or alternatively, the solar module mount can accommodate threaded rods and / or have screw connections for arrangement at a particularly vertical installation location.

[0021] A longitudinal extension of the solar module mount advantageously corresponds to a longitudinal extension of the solar module, and a transverse extension of the solar module mount corresponds to a transverse extension of the solar module. The longitudinal extension of the solar module mount is in particular 80 cm to 180 cm, and the transverse extension is 25 cm to 120 cm.

[0022] The solar module holder comprises in particular a “first frame element” and a “second frame element”.

[0023] The first frame element can have at least four outer frame profiles that essentially span a rectangle with a predefined longitudinal and transverse extension. The lateral frame profiles of the first frame element, which extend in the transverse extension of the solar module holder, can in particular be designed higher than the front and rear frame profiles, which extend in the longitudinal extension of the solar module holder.

[0024] The frame profiles can be made of plastic and / or metal, whereby the first frame element has an advantageously low weight.

[0025] Advantageously, the frame profiles are standardized extruded profiles, which enables easy production at essentially low production costs.

[0026] In particular, recesses into which a solar module can be inserted can be arranged on the first frame element. Additionally or alternatively, the first frame element can have holes, in particular threaded holes, by means of which a solar module arranged on the first frame element can be locked.

[0027] Additional or supplementary equipment of a solar power plant, such as cables, inverters or the like, can be arranged within the frame profiles of the first frame element.

[0028] The structure of the second frame element can essentially correspond to the structure of the first frame element. In particular, a longitudinal extension and / or a transverse extension of the second frame element advantageously corresponds to a longitudinal extension and / or transverse extension of the second frame element.

[0029] For stabilization purposes, struts can be arranged between the respective front and rear frame profiles on both the first frame element and the second frame element.

[0030] At least one adjustable connecting element is arranged between the first frame element and the second frame element. An “adjustable connecting element” is understood in particular to mean an automatically adjustable connecting element. The connecting element is connected on one side to the first frame element, directly and / or indirectly, permanently and / or temporarily, and on the other side to the second frame element, directly and / or indirectly, permanently and / or temporarily, permanently. By means of the adjustment, a length of the connecting element is adjusted, in particular. The connecting element can be designed as a single component or as a plurality of components. It is also possible to design it as two identical components.

[0031] The connecting element has in particular an actuator and / or a control device, which advantageously realize a change in length and / or a length adjustment.

[0032] The adjustable connecting element is arranged, in particular, directly and / or indirectly on the second frame element in spatial proximity to a central axis of the second frame element, and directly and / or indirectly on the first frame element at at least one first connection point in spatial proximity to the rear frame profile of the first frame element. Advantageously, the arrangement of the adjustable connecting element on the first frame element and the second frame element enables easy opening and closing of the solar module holder between a closed position and a maximum opening angle.

[0033] Additionally or supplementarily, the first frame element and the second frame element are rotatably connected to one another at a second connection point in spatial proximity to a respective front frame profile of the second frame element and the first frame element. In other words, the second connection point is substantially opposite the first connection point on the first frame element. Advantageously, an angle between the first frame element and the second frame element can be adjusted by means of the adjustable connecting element by rotating the first frame element about the second connection point. The adjustable angle can be between 5° and 60°, in particular between 15° and 45°.

[0034] A "first set angle" is understood to mean, in particular, the smallest possible angle between the first frame element and the second frame element. At the first set angle, the first frame element rests, in particular, completely on the second frame element. If a frame profile differs in height from at least one other frame profile, the first frame element rests on the second frame element, in particular with a frame profile that also has the greatest height.

[0035] At a first set angle between the first frame element and the second frame element, the solar module mount has a substantially flat cuboid shape. This advantageously provides the smallest possible surface area for the impact of wind force.

[0036] Further advantageously, at a first set angle between the first frame element and the second frame element, technical elements present in a cavity spanned by the two frame elements are protected from environmental influences by means of the solar module and the frame profiles of the first frame element and the second frame element.

[0037] In a further position of the first frame element relative to the second frame element, which corresponds to a "second set angle," the first frame element lifts at least partially from the second frame element. The spacing along the transverse extent is smaller in spatial proximity to the front frame profiles than in spatial proximity to the rear frame profiles. The lifting is advantageously achieved in particular by changing the length of the adjustable adjustment means and by the resulting rotation of the first frame element relative to the second frame element about the second connection point.

[0038] The second set angle can be 1° to 90°, in particular 1° to 75°. To achieve optimal positioning of the solar module relative to the sun, the second set angle can advantageously correspond to a current angle of incidence of the sun.

[0039] In one embodiment, the adjustable connecting element is continuously adjustable. In other words, the second set angle can be adjusted, in particular, within a predefined range. This advantageously allows for precise guidance of the solar module, taking into account the current solar radiation angle.

[0040] The adjustable connecting element can be designed as a hydraulic cylinder. Advantageously, a hydraulic cylinder can realize continuous adjustability of the first connecting element and is generally low-maintenance. Alternatively, the adjustable connecting element can be a pneumatic cylinder. This also advantageously realizes continuous adjustability of a second angle and a favorable operating medium. Finally, the adjustable connecting element can be a threaded rod with a spindle motor, which advantageously realizes continuous adjustability of the second angle and ensures extremely fine adjustment of the second angle as well as good locking capability.

[0041] In a further embodiment, the second frame element additionally has an adjustment means. The adjustment means is designed in particular for adjusting a rotation angle of the second frame element relative to an orientation of the first frame element. The adjustment means can be designed in two parts, with at least one part being a race. A race is understood in particular to be an annular first element which is contact-connected to a second annular element and / or a second connecting element. Additionally or additionally, the adjustment means can have a control unit which is designed to establish and lock a position of the adjustment means. Due to its shape, a race advantageously realizes a rotation of 360°.

[0042] The adjustment means can be connected to a control unit. The control unit can be configured to control both the adjustment means and the adjustable connecting element.

[0043] The adjustment means can be arranged spatially between the second frame element and the first frame element, wherein the adjustment means can be immersed in at least one of the frame elements at a first adjustable angle. Advantageously, the adjustment means supports the first frame element and the components temporarily and / or permanently arranged on the first frame element. The second connection point can be arranged, in particular, indirectly on the second frame element by being arranged on the adjustment means.

[0044] Additionally or alternatively, the adjustment means can be arranged below the second frame element, in other words, between the second frame element and a support surface. In the latter case, the adjustment means realizes a rotation of the second frame element and the first frame element relative to their surroundings.

[0045] In such an embodiment, the adjustment means is arranged, in particular, between a support surface of the first frame element and the second frame element. The adjustment means can be fixedly arranged on the support surface. The fixed arrangement can be realized, in particular, using a heavy material, such as concrete, and / or using a fastening means, such as a screw connection.

[0046] Alternatively, the second frame element can be designed in two parts as an upper second frame element and a lower second frame element and the adjusting means can be arranged in particular between the upper second frame element and the lower second frame element. In such a design, a position of the lower second frame element relative to the installation surface is in particular fixed and a rotation of the upper second frame element, on which the first frame element is arranged directly and / or indirectly, relative to the lower second frame element can be changed by means of the adjusting means. In this case, the rotatable connecting means between the first frame element and the second frame element is arranged in particular on the upper second frame element and likewise the adjustable connecting means between the first frame element and the second frame element.

[0047] In a further aspect, the object is achieved by a solar power plant comprising a solar module holder according to the invention and a sensor, wherein the solar power plant is configured to adjust a rotation angle of a second frame element with respect to an orientation of a first frame element of the solar module holder and / or an angle between the first frame element and the second frame element based on a sensor value of the sensor and using an adjusting means adjusting the rotation angle and / or an adjustable connecting means adjusting the angle.

[0048] Additionally or additionally, the solar power plant can have an evaluation unit, which is particularly programmed to determine a rotation angle and / or an angle between the first frame element and the second frame element based on the sensor value. This advantageously enables the determination of an optimal position of the solar module, which achieves an optimal angle of solar radiation onto the solar module.

[0049] In a further embodiment, the solar power plant additionally comprises an energy storage device. The energy storage device can comprise an accumulator and / or a battery. The energy stored in the energy storage device is used, in particular, to supply the adjustment means and / or the adjustable connecting means with electrical energy. Additionally or alternatively, the stored energy can be used to supply an evaluation unit and / or an adjustment means with electrical energy.

[0050] Advantageously, a solar power plant equipped with an energy storage device for adjusting the angle of rotation and / or the angle is self-sufficient from an external energy supply and can thus realize an adjustment of an angle and / or a rotation angle even if an external energy supply is not available.

[0051] The energy storage device can be designed to be charged with electrical energy generated by the solar power plant. Additionally or alternatively, the energy storage device can be charged using externally supplied electrical energy.

[0052] In a further embodiment, the solar power plant can additionally comprise a control unit. The control unit has, in particular, a data input, an evaluation unit, and a data output. The control unit is connected to the sensor via the data input, in particular for exchanging sensor data. Additionally or alternatively, the control unit is connected to the adjustment means via the data output, in particular for exchanging sensor data. Additionally or alternatively, the control unit is connected to the adjustable connecting means via the data output, in particular for exchanging sensor data.

[0053] The control unit is particularly configured to receive sensor data from the sensor, to determine, by means of the evaluation unit, a first position of the adjustment means and / or a second position of the adjustable connecting means corresponding to the sensor data, and to output a signal representing the first position to the adjustment means and / or a signal representing the second position to the adjustable connecting means. Thus, the solar power plant with the control unit is advantageously configured to determine an optimal position of the solar module based on a sensor value from the sensor and to output a signal to the adjustable connecting means and / or the adjustment means, so that the latter realizes or realizes the determined optimal position of the solar module in response to receiving the signal.

[0054] The connection between the data input and the sensor, the data output and the adjustment means, and / or the data output and the adjustable connecting means can be implemented via a wired connection. Additionally or alternatively, the connection between the data input and the sensor, the data output and the adjustment means, and / or the data output and the adjustable connecting means can be implemented wirelessly. A wired connection advantageously provides secure communication between the data input and the sensor, the data output and the adjustment means, and / or the data output and the adjustable connecting means, whereas a wireless connection advantageously requires fewer materials.

[0055] In one embodiment, the sensor is a wind sensor. A wind sensor is configured, in particular, to measure a wind speed and / or a wind direction. Advantageously, the solar power plant is configured, by means of a wind sensor, to determine a current wind force and / or, taking into account the current wind load, to determine an optimal positioning of the solar module and to output a signal to the adjustable connecting means and / or the adjusting means, which subsequently implement the optimal positioning of the solar module. In other words, a threshold value can be defined which represents an excessive wind load on the solar module, and a position of the solar module holder holding the solar module can be predefined, which is implemented as soon as the threshold value is reached and / or exceeded. The aforementioned position corresponds, in particular, to the first set angle.

[0056] Additionally or alternatively, the sensor can be a brightness sensor. A brightness sensor is particularly configured to detect brightness. Using a brightness sensor in a solar power plant, the position of the sun relative to the solar module can advantageously be determined. Further advantageously, based on the determined brightness value, an optimal position of the solar module held by the solar module holder can be determined to achieve the greatest possible energy generation.

[0057] Finally, the sensor can be a temperature sensor. Additionally or alternatively, the solar module can be guided based on a determined position of the sun and / or a determined wind load.

[0058] In addition to or as an alternative to guiding based on brightness and / or wind load, the solar module mount can be guided based on a predefined guide curve. The predefined guide curve includes, in particular, information on the seasonal and / or time-of-day dependent position of the sun in the sky. This advantageously allows for guiding the solar module without the need for a sensor.

[0059] The further features of the aspect, combinations of features and the advantages resulting from them correspond to those mentioned in connection with the first-mentioned aspect of the invention.

[0060] In a further aspect, the object is achieved by a method for adjusting a position of a solar power plant according to the invention, in particular of a solar module arranged in a solar power plant according to the invention. The method comprises receiving a first sensor value from a sensor by means of a control unit in a first step, wherein the sensor value represents an angle of solar radiation at a first point in time. The method also comprises the step of determining, by means of the control unit, an angle corresponding to the angle of solar radiation between a first frame element of the solar module holder of the solar power plant, which first frame element has the solar module, and a second frame element connected to the first frame element by means of an adjustable connecting means.In a further step, a signal is output by the control unit to an adjustment device of the adjustable connecting means, the signal representing the determined angle. In response, the first frame element is positioned in a further step by means of the adjustment device, taking the determined angle into account.

[0061] In this way, the method advantageously realizes an optimized positioning of the solar module corresponding to the angle of solar radiation.

[0062] In one embodiment of the method, this additionally comprises the step of determining a rotation angle of the second frame element corresponding to the solar radiation angle relative to an orientation of the first frame element, and outputting a second signal to an adjustment means configured to set a predefined rotation angle, wherein the second signal represents the determined rotation angle. In response to this, in a further step, the second frame element is positioned using the adjustment means and taking the determined rotation angle into account.

[0063] In this way, in addition to the optimized vertical adjustment of the solar module, a horizontal positioning of the solar module is advantageously realized, which corresponds to the angle of solar radiation.

[0064] The features, combinations of features and the resulting advantages of the first-mentioned aspect of the invention also apply to the latter aspect.

A solar module 109 is arranged on the first frame element 103 and is firmly connected to the first frame element 103. The mount 101 with the solar module 109 is positioned on a substantially horizontal support surface 129.
