Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic technology, and in particular to a solar photovoltaic module with enhanced light uniformity. Background Technology
[0002] A photovoltaic (PV) module is a small, indivisible assembly of solar cells that is encapsulated and internally connected, capable of providing direct current (DC) electricity independently. It utilizes the photovoltaic effect to directly convert light energy into electrical energy. With the development and application of PV technology, PV modules are increasingly used in agriculture. Among these, agricultural-photovoltaic complementary PV modules utilize PV panels to provide shade for farmland, improving the farmland environment, while crops can be grown beneath the panels, creating a complementary relationship and thus increasing land utilization.
[0003] The main components of a photovoltaic module include solar cells, EVA film, tempered glass, backsheet, and frame. Because the backsheet of a photovoltaic module is opaque, all sunlight is concentrated on the front of the module for absorption and conversion. This results in a significant reduction in the amount of light received by the area below the photovoltaic module, especially in areas directly shaded by the module, which will form shadow areas. Uneven light distribution and large variations in intensity will limit the amount of light received by crop leaves and affect crop growth. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that existing photovoltaic modules, due to the opaque backlight of the photovoltaic module, will form shadow areas in the areas directly blocked by the photovoltaic module, resulting in uneven light distribution and large intensity variations that will affect crop growth. Therefore, this utility model proposes a solar photovoltaic module with enhanced light uniformity.
[0005] To achieve the above objectives, the present invention employs the following technology: a solar photovoltaic module with enhanced light uniformity function, comprising a panel assembly, the panel assembly comprising an outer frame, on which parallel glass plates and light uniform plates are disposed, and a battery cell is disposed on the outer frame between the glass plates and the light uniform plates via an EVA film, and an adjustment mechanism for adjusting the amount and distribution of light is disposed at the bottom of the outer frame.
[0006] As a further description of the above technical solution: the adjustment mechanism includes a fixed frame connected to the outer frame, a first perforated plate is provided on the fixed frame, and a second perforated plate is slidable in a direction parallel to the first perforated plate. One end of the fixed frame is provided with a positioning component for positioning and fixing the second perforated plate.
[0007] As a further description of the above technical solution: a slide rail is provided on the second perforated plate, and a handle is provided on one end of the second perforated plate extending out of the fixing frame. The fixing frame is provided with a slide groove that cooperates with the slide rail.
[0008] As a further description of the above technical solution: a cleaning component is provided on the second perforated plate via a slot;
[0009] The cleaning component includes a positioning plate that mates with a slot, and a cleaning cotton that contacts the light-diffusing plate is provided on the positioning plate.
[0010] As a further description of the above technical solution: the two ends of the positioning plate are provided with limit blocks through the mounting groove, and a spring is provided between the limit block and the inner wall of the mounting groove;
[0011] The inner wall of the slot is provided with a limiting hole that cooperates with the limiting block.
[0012] As a further description of the above technical solution: the limiting block is provided with a pull plate with a through slot.
[0013] As a further description of the above technical solution: the positioning component includes a positioning frame fixed on a fixed frame, and a gasket is provided on the positioning frame by means of a screw.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] By replacing the backlight panel on a traditional photovoltaic module with a light-diffusing panel, the light-diffusing panel has a higher light transmittance, allowing more light to penetrate the backlight panel and illuminate the object or ground below the photovoltaic module. It can evenly disperse the light, reduce the generation of light spots and shadows, and thus improve the uniformity of illumination.
[0016] The back of the photovoltaic module is equipped with an adjustable aperture plate, which can further enhance the light uniformity effect. By adjusting the size of the aperture on the aperture plate, the amount of light entering the photovoltaic module and the distribution of light can be controlled. When it is necessary to increase the amount of light, the size of the aperture can be increased. When it is necessary to reduce the amount of light or optimize the light distribution, the size of the aperture can be decreased or the position of the aperture can be changed. This flexibility allows the photovoltaic module to adapt to different lighting conditions and environmental requirements to achieve the best power generation effect. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figures 1-7 This embodiment provides a solar photovoltaic module with enhanced light uniformity, including a panel assembly 10. The panel assembly 10 includes an outer frame 11, on which a glass plate 12 and a light uniform plate 13 are arranged in parallel. A battery cell 15 is disposed on the outer frame 11 between the glass plate 12 and the light uniform plate 13 through an EVA film 14. An adjustment mechanism 20 for adjusting the amount and distribution of light is provided at the bottom of the outer frame 11.
[0029] In this invention, a glass plate 12, a light-diffusing plate 13, an EVA film 14, and a solar cell 15 are arranged inside an outer frame 11 to form a photovoltaic system panel assembly 10. The light-diffusing plate 13 is a glass light-diffusing plate. By replacing the backlight on a traditional photovoltaic module with the light-diffusing plate 13, more light can be allowed to penetrate the backlight and illuminate the object or ground below the photovoltaic module. This can evenly disperse the light, reduce the generation of light spots and shadows, and thus improve the uniformity of illumination.
[0030] Specifically, such as Figures 1-3 As shown, the adjustment mechanism 20 includes a fixed frame 21 connected to the outer frame 11. The fixed frame 21 is provided with a first perforated plate 22 and a second perforated plate 23 that can slide in a direction parallel to the first perforated plate 22. One end of the fixed frame 21 is provided with a positioning component 24 for positioning and fixing the second perforated plate 23. The second perforated plate 23 is provided with a slide rail 231, and one end of the second perforated plate 23 extending out of the fixed frame 21 is provided with a handle 232. The fixed frame 21 is provided with a slide groove that cooperates with the slide rail 231.
[0031] The holes of the first perforated plate 22 and the second perforated plate 23 on the fixing frame 21 of the adjustment mechanism 20 are the same in size and arrangement. When it is necessary to increase the amount of light, the holes of the first perforated plate 22 and the second perforated plate 23 are aligned to achieve the maximum hole size. When it is necessary to reduce the amount of light or optimize the light distribution, the positioning component 24 is opened, and then the second perforated plate 23 is pulled by the handle 232. The second perforated plate 23 slides under the cooperation of the slide rail 231 and the slide groove. At this time, the holes of the second perforated plate 23 are misaligned with the holes of the first perforated plate 22, which can reduce the size of the holes or change the position of the holes, so that the photovoltaic module can adapt to different light conditions and environmental requirements and achieve the best power generation effect.
[0032] It should be noted that, as Figure 1 and Figure 6 As shown, the positioning assembly 24 includes a positioning frame 241 fixed on the fixing frame 21. A washer 243 is provided on the positioning frame 241 via a screw 242. When the second perforated plate 23 needs to be moved, the screw 242 on the positioning frame 241 is turned, causing the screw 242 to move the washer 243 downward. The pressure of the washer 243 and the positioning frame 241 on the second perforated plate 23 decreases, and the second perforated plate 23 can be moved at this time. After the second perforated plate 23 is moved, the screw 242 is tightened again, and the second perforated plate 23 is fixed by the clamping force of the washer 243 and the positioning frame 241. The washer 243 is made of rubber, which can increase the friction to ensure the stability of the position of the second perforated plate 23 while avoiding the formation of indentations on the second perforated plate 23, thus improving safety.
[0033] Specifically, such as Figures 2-4As shown, a cleaning component 234 is provided on the second perforated plate 23 via a slot 233. The cleaning component 234 includes a positioning plate 2341 that cooperates with the slot 233. A cleaning cotton 2342 that contacts the light-diffusing plate 13 is provided on the positioning plate 2341.
[0034] The second perforated plate 23 can be pulled and moved to adjust the size of the holes on the first perforated plate 22 and the second perforated plate 23. When the second perforated plate 23 moves, the cleaning component 234 moves with the second perforated plate 23, and then the cleaning cotton 2342 on the positioning plate 2341 cleans the light uniform plate 13 to ensure that dust and other impurities do not adhere to the surface of the light uniform plate 13 during use, thereby further improving the light uniformity of the photovoltaic system.
[0035] Specifically, such as Figures 3-5 As shown, the two ends of the positioning plate 2341 are provided with limit blocks 2344 through the mounting groove 2343. A spring 2345 is provided between the limit block 2344 and the inner wall of the mounting groove 2343. A limit hole that cooperates with the limit block 2344 is provided on the inner wall of the slot 233. A pull plate 2347 that passes through the slot 2346 is provided on the limit block 2344.
[0036] When the cleaning component 234 needs to be disassembled to clean the cleaning cotton 2342, the limiting block 2344 is pulled by the pull plate 2347, causing the limiting block 2344 to compress the spring 2345 and retract into the mounting groove 2343. This allows the limiting block 2344 to disengage from the limiting hole in the slot 233. Then, the positioning plate 2341 can be pulled out to disassemble the cleaning component 234. During installation, the limiting block 2344 is retracted first. After the positioning plate 2341 is inserted into the slot 233, the pull plate 2347 is released. Then, the limiting block 2344 pops out under the action of the spring 2345 and is locked in the limiting hole of the slot 233. This facilitates the installation and disassembly of the cleaning component 234, making it easier to clean and replace it.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
