Photovoltaic modules are the main power generation equipment in a solar power plant, and the amount of light received by photovoltaic modules is directly related to the power generation of the solar power plant.

[0003] Traditional photovoltaic modules have an A-side frame. After photovoltaic modules are operated outdoors, they accumulate a lot of dust. When it does not rain for a long time and is not cleaned, the dust accumulation will affect the power generation efficiency and may even lead to module failure. Utility Model Content

[0004] The purpose of this invention is to provide a distributed solar power station and photovoltaic modules to solve the problem that photovoltaic modules easily accumulate a lot of dust after being operated outdoors, which affects the power generation efficiency of the photovoltaic modules.

[0006] A color steel sheet roof, wherein the color steel sheet roof has multiple parallel and spaced-apart wave peaks;

[0007] A photovoltaic module is arranged at an angle relative to the horizontal plane on the color steel roof. The photovoltaic module includes a laminate and a frame surrounding the laminate. The frame includes a pair of long frames and a pair of short frames. The long frames include a first long frame and a second long frame opposite to each other. The first long frame and the second long frame are transverse to the crest. The first long frame is positioned at a lower position relative to the second long frame. The first long frame does not have a portion covering the front surface of the laminate.

[0008] And connecting components that connect the first long frame and the second long frame to the wave crest.

[0009] In some embodiments, the first long frame includes a frame body, the top of which has a support platform, and the support platform has a protective wall located on the outside of the laminate, the height of which does not exceed the front surface of the laminate.

[0010] In some embodiments, the upper surface of the support platform has a glue storage tank.

[0011] In some embodiments, the inner side of the protective wall is provided with an anti-overflow adhesive groove.

[0012] In some embodiments, the outer side of the long frame is provided with a mounting groove, the mounting groove has an open opening, and the lower edge of the opening has a limiting portion.

[0013] In some embodiments, one side of the connecting member extends into the mounting groove and engages with the limiting portion.

[0014] In some embodiments, the long frame includes a frame body, a base plate extending outward from the frame body, and a limiting portion disposed on the upper surface of the base plate, wherein the mounting groove is formed above the base plate.

[0015] In some embodiments, the connecting member includes a pressure block and a clamp, one side of the pressure block extending into the mounting groove, the pressure block being connected to the clamp, and the clamp holding the crest.

[0016] In some embodiments, the second long frame may or may not have a portion covering the front surface of the laminate, and / or the short frame may or may not have a portion covering the front surface of the laminate.

[0017] A photovoltaic module includes a laminate and a frame surrounding the laminate. The frame includes a pair of long frames and a pair of short frames. The long frames include a first long frame and a second long frame opposite to each other. The outer side of the long frame is provided with a mounting groove.

The support platform is provided with a protective wall located on the outer side of the laminate. The height of the protective wall does not exceed the front surface of the laminate.

[0018] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0019] In the distributed solar photovoltaic module of this invention, at least the first long frame located at the lower position does not have a portion covering the front surface of the laminate, i.e., it has no A-side. Rainwater will wash the dust on the surface of the photovoltaic module downwards.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2 This utility model provides a distributed solar power station, including a color steel roof 1, photovoltaic modules, and connecting members 4. The color steel roof 1 has multiple parallel and spaced-apart peaks 10. The photovoltaic modules are arranged at an angle relative to the horizontal plane on the color steel roof 1. The photovoltaic modules include a laminate 3 and a frame surrounding the laminate 3. The frame includes a pair of long frames 21 and a pair of short frames 22. The long frames 21 include a first long frame and a second long frame opposite to each other. The first long frame and the second long frame are transverse to the peaks 10. The first long frame is positioned lower than the second long frame. The first long frame does not have a portion covering the front surface of the laminate 3. The connecting members 4 connect the first long frame and the second long frame to the peaks 10.

[0033] The first long frame does not have a portion covering the front surface of the laminate 3, meaning the first long frame has no A-side. The long frame is transverse to the crest 10 of the corrugated steel roof 1, while the short frame runs vertically along the roof. More photovoltaic modules can be arranged vertically on the corrugated steel roof 1, increasing the installed capacity of photovoltaic modules. Since the long frame of the photovoltaic module is longer than the short frame, the horizontal mounting method exacerbates the dust accumulation phenomenon of traditional photovoltaic modules. However, in the distributed solar power station of this application, the first long frame, at least at the lower position, has no A-side. Rainwater will wash the dust on the surface of the photovoltaic module downwards. Since the first long frame has no A-side, the frame will not obstruct the downward flow of rainwater, reducing the accumulation of dust and rainwater at the lower front of the photovoltaic module, thereby reducing the shading of the photovoltaic module by dust. This approach leverages the advantages of horizontal mounting while solving the dust accumulation problem.

[0034] In some embodiments, the first long frame includes a frame body 210, with a support platform 211 at its top. A laminate 3 is placed on the support platform 211, and the frame body 210 can support the photovoltaic module. A protective wall 213 is provided on the support platform 211, located outside the laminate 3. The protective wall 213 protects the sides of the laminate 3 and limits its position. The height of the protective wall 213 does not exceed the front surface of the laminate 3, thus preventing the frame from obstructing the downward flow of rainwater.

[0035] In some embodiments, the upper surface of the support platform 211 has a glue storage tank 212. During the photovoltaic module encapsulation process, the glue stored in the glue storage tank 212 can ensure sufficient adhesion between the frame and the laminate 3.

[0036] In some embodiments, the inner side of the protective wall 213 is provided with an anti-overflow adhesive groove 214, which can store adhesive and reduce the risk of adhesive overflowing onto the front surface of the laminate 3 during the encapsulation of the photovoltaic module.

[0037] In some embodiments, the outer side of the long frame 21 is provided with a mounting groove 216, the mounting groove 216 has an open slot, the lower edge of the slot has a limiting part 218, and one side of the connecting member 4 extends into the mounting groove 216 and engages with the limiting part 218.

[0038] The photovoltaic module disclosed herein directly connects the long frame 21 to the corrugated steel roof crest 10 via connecting member 4, saving guide rails and reducing power plant investment costs. In traditional photovoltaic module installation structures, the pressure block directly presses onto the A-side of the photovoltaic module frame. However, since the first long frame of this disclosure lacks an A-side, directly pressing the pressure block onto the front surface of the photovoltaic module could easily cause the glass of the laminate 3 to shatter. This disclosure solves the installation problem of photovoltaic modules without an A-side by providing an installation groove 216 on the outer side of the long frame 21 and utilizing the limiting relationship between the pressure block and the installation groove 216 to achieve the installation of the photovoltaic module.

[0039] Specifically, such as Figure 2 As shown, the long frame 21 includes a frame body 210, a base plate 217 extending outward from the frame body 210, and a limiting part 218 provided on the upper surface of the base plate 217, with a mounting groove 216 formed above the base plate.

[0040] In some embodiments, the connecting member 4 includes a pressure block 40 and a clamp 41. One side of the pressure block 40 extends into the mounting groove 216, and the pressure block 40 is connected to the clamp 41, which clamps the wave crest 10. The pressure block 40 applies downward pressure to the long frame 21 and forms a hook-lock structure with the limiting portion 218.

[0041] In some embodiments, the clamp 41 includes a first connecting block 41 and a second connecting block 42, wherein the first connecting block 41 and the second connecting block 42 cooperate to clamp the wave crest 10.

[0042] In a preferred embodiment, the first connecting block 41 includes a first connecting horizontal plate 4112 detachably connected to the pressure block 40 and a first clamping plate 4111 connected below the first connecting horizontal plate 4112. The second connecting block 42 includes a second clamping plate 4121. The inner surfaces of the first clamping plate 4111 and / or the second clamping plate 4121 are provided with clamping grooves. The clamping grooves and another clamping plate or another clamping groove form a clamping space with a clamping crest 10. The first clamping plate 4111 and the second clamping plate 4121 are connected together by bolts. Figure 3 As shown.

[0043] In another preferred embodiment, the first connecting block 41 includes a first connecting horizontal plate 4112 and a first clamping plate 4111 connected below the first connecting horizontal plate 4112. The second connecting block 42 includes a second connecting horizontal plate 4122 and a second clamping plate 4121 connected below the second connecting horizontal plate 4122. The pressure block 40, the first connecting horizontal plate 4112, and the second connecting horizontal plate 4122 are stacked sequentially and fixed together with bolts. The inner surface of the first clamping plate 4111 and / or the second clamping plate 4121 is provided with a clamping groove, and the clamping groove and another clamping plate or another clamping groove form a clamping space with a clamping crest 10, such as... Figure 4 As shown.

[0044] In some embodiments, the second long border may or may not have a portion covering the front surface of the laminate 3, and / or the short border 22 may or may not have a portion covering the front surface of the laminate 3. Specifically, the second long border may have an A-side border or may not have an A-side border. The short border 22 may have an A-side border or may not have an A-side border.

[0045] Example 2

[0046] Reference Figure 1 and Figure 2 This utility model provides a photovoltaic module, including a laminate 3 and a frame surrounding the laminate 3. The frame includes a pair of long frames 21 and a pair of short frames 22. The long frames 21 include a first long frame and a second long frame opposite to each other. The outer side of the long frames 21 is provided with a mounting groove 216. The mounting groove 216 has an outward-facing opening. The lower edge of the opening has a limiting part 218. The first long frame includes a frame body 210. The top of the frame body 210 has a support platform 211. The support platform 211 is provided with a protective wall 213 located on the outer side of the laminate 3. The height of the protective wall 213 does not exceed the front surface of the laminate 3.

[0047] This utility model's photovoltaic module has no A-side on its first long frame. When the photovoltaic module is installed at an angle and the first long frame is set at a low position, rainwater will wash the dust on the surface of the photovoltaic module downwards. Since the first long frame has no A-side, the frame will not obstruct the downward flow of rainwater, reducing the accumulation of dust and rainwater at the lower front of the photovoltaic module. This reduces the shading of the photovoltaic module by dust, increases the power generation of the photovoltaic module, and reduces the cleaning cost of the photovoltaic module.

[0048] In some embodiments, the upper surface of the support platform 211 has an adhesive reservoir 212, which stores adhesive to ensure sufficient adhesion between the frame and the laminate 3.

[0049] In some embodiments, the inner side of the protective wall 213 is provided with an anti-overflow adhesive groove 214, which can further prevent the adhesive from overflowing onto the front surface of the laminate 3 during the encapsulation of the photovoltaic module.

[0050] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
