Description

[0001] Solar panel mounting system

[0002] Field of technology

[0003] The invention relates to solar energy, in particular to the field of solar panel mountings.

[0004] State of the art

[0005] Numerous devices for mounting solar panels on pitched roofs are known. A device described at htp: / / www.chikosolar.com.cn.product-detail / 7-solar-rail-system.html, which uses a system of rails and anchors to secure the solar panel, can be considered as an analogue of the proposed invention. This analogue has a feature similar to the claimed invention—such a mounting system can be used on all types of pitched roofs, but it has the disadvantage of requiring holes in the roof. Another analogue can be considered: a device described at htps: / / www.sunballast.it / en, which uses weights to prevent the solar panels from shifting. This analogue has the same feature—no need to drill holes in the roof—as the claimed invention, but this analogue requires additional weighting of the structure.A prototype of the proposed invention is the device described on the website https: / / www.artsignenergy.com / best-non-penetrating-solar-panel-roof-mounting-systems_pl72.html, in which the solar panel is mounted on seams arranged longitudinally along the roof slope. This prototype shares the same feature—no need for holes in the roof—as the claimed invention. However, it has some drawbacks, as the entire load from the solar panel mounting system is supported solely by the seam, which has low load-bearing capacity and is only suitable for use on standing seam roofs.

[0006] Disclosure of invention

[0007] The objective of the present invention is to create a universal system for mounting solar panels on roofs with different types of coverings, which does not require the use of weights and does not require the production of holes in the roofs.

[0008] The technical result achieved through the implementation of this invention is the absence of the need to make holes in the roof when installing a solar panel mounting system on any type of roof, and there is no need to install any weights.

[0009] An additional objective of the claimed invention is to reduce the labor intensity of installing the SCSP on the roof using lifting mechanisms, with minimal use of manual labor.

[0010] An additional technical result is the possibility of creating a type of SCSP that allows for the entire internal installation of the SCSP to be carried out on the ground, in a factory setting, and for roof installation to be carried out in assembled form, using lifting mechanisms, with minimal use of manual labor.

[0011] An additional objective of the claimed invention is to create effective protection for solar panels from hail, snow, and ice, with the ability to clean both the solar panels and the protection itself from precipitation, dust, and dirt without the use of manual labor.

[0012] An additional technical result is the possibility of creating a protection system and cleaning systems, the installation of which, due to their complexity, is expediently carried out on the ground, in factory conditions.

[0013] Solar panel mounting systems on roofs, hereinafter also referred to as SCPS, typically consist of several main components:

[0014] - weights that bear the load from the solar panel mounting system and remain motionless due to their mass and the force of friction against the roof surface;

[0015] - an anchor attached to a weight or to the supporting elements of the roof through an opening in the roof material;

[0016] - a curved plate attached to this anchor;

[0017] - a support rail attached to a curved plate or to an anchor;

[0018] - brackets attached to these support rails;

[0019] - solar panels located on support rails or brackets.

[0020] The tasks solved by the SCSP installation boil down to power generation. To ensure uninterrupted power supply, attention must be paid to securely mounting the solar panels, preventing them from being torn off by wind and snow, and ensuring they can be maintained, protected from hail, removed from dirt, snow, ice, dust, and bird droppings, and repaired and replaced if damaged. The objective of this invention is to create a solar panel mounting system that accomplishes these tasks without drilling any holes in the roof.

[0021] This problem is solved by using a counterweight beam 6, located on the roof slope 1, and connected to a supporting beam 3, located on the other roof slope 1. If necessary, the supporting beam 3 and the counterweight beam 6 can be equipped with supports 2.

[0022] The feature of using a counterweight beam 6, located on the other slope of the roof 1, connected to the supporting beam 3 is a necessary element of the invention, since it is this new technical solution that allows for an inventive step - to compensate for the weight of the supporting beam 3 and all parts connected to it, thereby creating the necessary clamping force, previously obtained by using anchors mounted through openings in the roof.

[0023] This feature allows, firstly, to eliminate the need to make any openings in the roof, secondly, to use such a design on any type of roof with different coverings, thirdly, to reduce labor costs for installing solar panels 5, fourthly, to provide the possibility of placing protective segments such as blinds and mechanisms for their movement, fifthly, to place a mechanism for cleaning solar panels on the moving segments of the protection, for example, a brush with a cleaning solution, and sixthly, to place a scraper for cleaning the blind segments from snow and ice when these segments move.

[0024] The features specified in the independent claims characterize particular methods for implementing the proposed invention. The use of supports 2 allows for the load from the SC SP to be concentrated in the locations of the load-bearing roof elements (above the purlins and rafters). The use of an elastic material in the composition of support 2 or beams 3 and 6 allows for the load from the SC SP to be uniformly distributed onto the surface of roof 1. Fastening the counterweight beam 6 and / or the load-bearing beam 3 to the lower surface of roof overhang 1 using grips 12 allows for an increase in the force of their clamping to roof 1. The use of a hinged mount 7 allows for compensation for differences in angles between different slopes of roof 1. The installation of the claimed SCSP devices, pre-assembled on the ground, using lifting mechanisms allows for a reduction in labor costs for creating a solar power plant. The use of louver segments 8 allows for the protection of solar panels 5 from hail, snow, and pollution.The use of a cleaning mechanism in the form of a clip 10 allows for cleaning of solar panels 5. The use of a scraper 10 allows for cleaning of louver segments 8 and removal of ice and snow. The previously unused arrangement of louver segments 8 below and above solar panels 5 allows for a smaller overall footprint of the SCSP structure and the elimination of a separate louver drum 9 for storing louver segments 8 in the open position.

[0033] Bearing beam 3

[0034] Bracket 4

[0035] Solar panel 5

[0036] Counterweight beam 6

[0045] Implementation of the invention

[0046] The claimed system can be implemented in the form of at least one support beam 3, resting on at least one support 2, located on one of the roof slopes 1, having, if necessary, brackets 4, a solar panel 5, a counterweight beam 6, connected to another support 2, located on another roof slope 1, these beams 3 and 6 are connected to each other rigidly or by a hinged mount 7.

[0047] Since the counterweight beam 6 is located on the other slope of the roof 1, its weight, through a rigid or hinged mount 7, compensates for the weight of the supporting beam 3 with the supports 2, brackets 4, solar panels 5 attached to it, and therefore the claimed device does not require the use of openings in the roof.

[0048] Inside the supporting beam 3 or between two supporting beams 3, there are connected segments of blinds 8, which move under the action of blind shafts 9. The specific implementation of the connection and automatic movement of the segments of blinds 8, the use of an electric drive, automation and telemechanics for this purpose, as well as the design of the blind shafts 9 are known to a person skilled in the art and are not considered in this invention.

[0049] The solar panel mounting system operates as follows: The weight of the supporting beam 3, support 2, brackets 4, solar panels 5, when interacting with one roof slope 1 through a rigid connection or hinged connection 7, is transferred to the counterweight beam 6, which rests through the support 1 on the other roof slope 1, and thereby keeps the supporting beam 3 with all parts attached to it from sliding down the roof slope 1.

[0050] If necessary, the counterweight beam 6 and / or the supporting beam 3 can be attached with clamps 12 to the lower surface of the overhang of the roof slopes 1, which will create additional fastening of the beams 3 and 6 to the roof 1.

[0051] The possibility of using grips 12, attached to the lower roof overhang and / or to other supporting structures, including the ground using anchors, makes it possible to secure such a SKSP on flat roofs.

[0052] A mechanism for moving the blind segments 8, known from the prior art, can be attached to the supporting beam 3, in the form of one blind shaft 9 with a storage unit for the blind segments 8, or in the form of two blind shafts 9, moving the blind segments 8 from a closed position (above the solar panels 5) to an open position (below the solar panels 5).

[0053] A scraper 10 can be attached to one of the shafts of the blinds 9, which throws snow off the segments of the blinds 8 as they move.

[0054] In one embodiment of the claimed invention, solar panels and / or brackets and / or blind segments with a blind shaft and / or a scraper are also located on a counterweight beam, which is relevant when the roof ridge is located in a direction close to the North = South line.

[0055] In another embodiment of the claimed invention, the supporting beam 3, on which solar panels are located, and / or brackets, and / or blind segments with a blind shaft, and / or a scraper are placed on a pitched roof 1 and secured with clamps 12.

[0056] Between adjacent supporting beams 3 and / or counterweight beams 6, it is possible to attach steps 11, facilitating the maintenance of solar panels.

[0057] 5.

[0058] It is also possible to have a solar panel mounting system in which the position of the blind segments 8 can be controlled using an automatic device, taking into account information received from sensors and the Internet about weather conditions, time of year and time of day.

[0059] An important feature of the proposed solar panel mounting system is the ability to assemble the solar panel mounting system 5 in factory conditions, on the ground, and deliver it to the roof in assembled form using a lifting mechanism. The presence of a feature... a counterweight beam located on the other slope of the roof.

[0060] 6, connected to the supporting beam 3... is a necessary element of the invention, since this new technical solution allows for an inventive step - to accept the load from the solar panels located on the supporting beam and their fastening system onto the counterweight beam, creating the possibility of fastening the SCSP without fastening holes in the roof.

[0061] The feature... consisting of at least one supporting beam, on this supporting beam directly or through at least one bracket connected to the supporting beam at least one solar panel is located... makes it possible to technically implement the following feature of the invention:... the solar panel fastening system is assembled on the ground and is delivered to the roof in assembled form by a lifting mechanism....

[0062] The above combination of features comprises an inventive step and makes it possible to solve the stated technical problem: to assemble a solar roofing system (SRS) with solar panels 5, louver segments 8, louver shafts 9, automatic control devices, inverters, etc. entirely on the ground, under factory conditions, test its operability, and mount it on a roof 1 without making openings in the roof, using lifting mechanisms and with minimal use of manual labor when working at height. This problem is solved by using a counterweight beam 6 located on the slope of the roof 1 and connected to a supporting beam 3 located on the other slope of the roof 1. If necessary, supporting beam 3 and counterweight beam 6 can be equipped with supports 2.

[0063] The feature of using a counterweight beam 6, located on the other slope of the roof 1, connected to the supporting beam 3 is a necessary element of the invention, since it is this new technical solution that allows for an inventive step - to compensate for the weight of the supporting beam 3 and all parts connected to it, thereby creating the necessary clamping force, previously obtained by using anchors mounted through openings in the roof.

[0064] This feature allows, firstly, to eliminate the need to make any openings in the roof 1, secondly, to use such a design on any types of roofs 1 with different coverings, thirdly, to reduce labor costs for installing solar panels 5, fourthly, to provide the possibility of placing on a rigid supporting beam 3 and / or on a counterweight beam 6 protection of solar panels 5 of the type of blind segments 8, and mechanisms for their movement (blind drums 9), fifthly, to place on the movable segments of blinds 8 a mechanism for cleaning solar panels 11 known from the prior art, for example a brush with a detergent, and sixthly, to place in the lower part of the beams 6 and / or 3 a scraper 10 for cleaning the segments of blinds 8 from snow and ice during the movement of these segments of blinds 8.

[0065] The claimed features characterize particular methods for implementing the proposed invention. The use of supports 2 allows for the load from the SKSP to be concentrated in the locations of the roof's load-bearing elements (above the purlins and rafters). The use of an elastic material in support 2 or beams 3 and 6 allows for the load from the SKSP to be uniformly distributed across the roof surface 1. Fastening the counterweight beam 6 and / or the load-bearing beam 3 to the lower surface of the roof overhang 1 using grips 12 allows for an increase in the force of their clamping to the roof 1. The use of a hinged mount 7 allows for compensation for angle differences between different roof slopes 1. The installation of the claimed SKSP devices, pre-assembled on the ground, using lifting mechanisms allows for a reduction in labor costs for creating a solar power plant. The use of louver segments 8 allows for the protection of solar panels 5 from hail, snow, and dirt. The use of a cleaning mechanism in the form of a clip 10 allows for the cleaning of solar panels 5.The use of scraper 10 allows for cleaning of louver segments 8 and removal of ice and snow. The previously unused placement of louver segments 8 above and below solar panels 5 allows for a smaller footprint of the SC SP structure and eliminates the need for a separate louver drum 9 for storing louver segments 8 in the open position.
