Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic cells, and particularly relates to a full-screen photovoltaic module. Background Art

[0002] At present, large-scale ground photovoltaic power stations generally have a large installed capacity, a large amount of installation work, and complex operation and maintenance. In contrast, distributed photovoltaic power stations are favored by household customers. However, distributed power stations have more stringent requirements for the appearance and electrical performance of photovoltaic modules than conventional modules.

[0003] Currently, the photovoltaic module selects a card slot with an inward opening at the upper end of the frame, and the edge of the laminate is inserted into the card slot. However, in the actual power station application, the disadvantages of this photovoltaic module frame are also obvious: that is, after the frame is installed, the top of the card slot of the frame exceeds the upper surface of the photovoltaic module by a certain height. Therefore, a closed enclosure is formed around the laminate. The dirt washed by rain on the upper surface of the laminate cannot flow away due to the blockage of the enclosure and accumulates in the enclosure at the top of the frame. If this continues for a long time, dirt and foreign matter will accumulate on the upper surface of the photovoltaic module, blocking the solar cells, affecting the power generation of the photovoltaic module, and easily generating hot spots on the module, threatening the safety of the module; in addition, the accumulation of dust at the edge of the frame enclosure also affects the aesthetics of the module. Summary of the Utility Model

[0004] An embodiment of the utility model provides a full-screen photovoltaic module, aiming to solve the problems that the power generation efficiency of the photovoltaic module is affected by the blockage of the frame and the accumulation of dirt and foreign matter on the upper surface, and the existing safety hazards.

[0005] To achieve the above object, the technical solution adopted by the utility model is: to provide a full-screen photovoltaic module, including:

[0006] A frame having a rectangular frame body, the top plate of the rectangular frame body extends outward from the frame to form an upper mounting plate; the bottom plate of the rectangular frame body extends inward from the frame to form a lower mounting plate; and

[0007] A photovoltaic laminate, along its periphery, a plurality of mounting holes are dispersedly arranged. The photovoltaic laminate is supported on the support plane formed by the top plate and the upper mounting plate, and is fastened to the upper mounting plate through bolts penetrating the mounting holes.

[0008] In an implementable manner, a counterbore is provided at the upper end of the mounting hole, so that the nut of the bolt is hidden in the counterbore.

[0009] In an implementable manner, a protective gasket sleeve is provided in the counterbore. The protective gasket sleeve has a protective sleeve attached to the side wall of the counterbore and a protective gasket attached to the step surface of the counterbore.

[0010] In an implementable manner, the thickness of the protective pad sleeve is 0.5 mm - 2 mm.

[0011] In an implementable manner, the protective pad sleeve is made of rubber or silica gel.

[0012] In an implementable manner, the depth of the counterbore is less than half of the thickness of the photovoltaic laminate.

[0013] In an implementable manner, an adhesive layer for bonding the photovoltaic laminate is laid on the support plane.

[0014] In an implementable manner, the adhesive layer is silica gel and / or double-sided tape.

[0015] In an implementable manner, the spacing between the mounting holes is 50 mm - 200 mm.

[0016] Compared with the prior art, the full-screen photovoltaic module provided by the present utility model has the beneficial effects that: the top plate of the frame extends outward to form an upper mounting plate for mounting the photovoltaic laminate, and at the same time, the upper mounting plate is flush with the top plate of the frame to form a support plane. The photovoltaic module is directly supported on the support plane and fastened to the upper mounting plate by bolts. There is no blocking enclosure around the upper surface of the photovoltaic laminate. The dirt washed by rain on the upper surface of the photovoltaic laminate will be washed away along with the rain and will not be blocked by the enclosure, and there will be no foreign matter accumulation on the upper surface of the photovoltaic laminate. This not only avoids the problem of dirt and foreign matter accumulation blocking the solar cells and affecting the power generation effect of the photovoltaic module, but also avoids the hidden danger that the accumulated foreign matter and dirt cause hot spots at this position of the photovoltaic module and threaten the safety of the module. Moreover, since the dust or debris on the photovoltaic module will be washed away by rain, it is equivalent to a natural cleaning of the upper surface of the photovoltaic module, which will not affect the appearance of the photovoltaic module and also improves the cleanliness of the photovoltaic module.

[0017] Therefore, due to the adoption of a frame with no upper surface obstruction, the upper surface of the photovoltaic laminate forms a full-screen light-receiving surface in the photovoltaic module provided in this application. There is no need to worry about the risk of the upper surface of the photovoltaic module being blocked by dirt and foreign matter, which greatly improves the power generation efficiency of the photovoltaic module. Also, due to the natural cleaning of rain, the power generation efficiency of the photovoltaic module is not affected, and the overall appearance is more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figures 1 to 8 together, and now the full-screen photovoltaic module provided by the present utility model will be described. The full-screen photovoltaic module includes: a frame 2 and a photovoltaic laminate 1. The frame 2 has a rectangular frame 22. The top plate of the rectangular frame 22 extends outward from the frame 2 to form an upper mounting plate 23; the bottom plate of the rectangular frame 22 extends inward from the frame 2 to form a lower mounting plate 21; the rectangular frame 22 has a strong supporting effect. The upper mounting plate 23 is used for the installation of the photovoltaic laminate 1 and the frame 2, and the lower mounting plate 21 is used to be fixed to the photovoltaic module bracket. An adjustment hole 26 is provided on the lower mounting plate 21.

[0030] A plurality of mounting holes 12 are dispersedly arranged around the photovoltaic laminate 1. The photovoltaic laminate 1 is supported on a support plane 24 formed by the top plate and the upper mounting plate 23, and is fastened to the upper mounting plate 23 by bolts 3 passing through the mounting holes 12.

[0031] Compared with the prior art, the full-screen photovoltaic module provided by the present utility model has the beneficial effects that: the top plate of the frame 2 extends outward to form an upper mounting plate 23 for mounting the photovoltaic laminate 1. At the same time, the upper mounting plate 23 is flush with the top plate of the frame 2 to form a support plane 24. The photovoltaic module is directly supported on the support plane 24 and is fastened to the upper mounting plate 23 by bolts 3. There is no blocking enclosure around the upper surface of the photovoltaic laminate 1. The dirt washed by rain on the upper surface of the photovoltaic laminate 1 will be washed away along with the rain and will not be blocked by the enclosure, and there will be no foreign matter accumulated on the upper surface of the photovoltaic laminate 1. This not only avoids the problem that dirt and foreign matter accumulation block the solar cells and affect the power generation effect of the photovoltaic module, but also avoids the hidden danger that the accumulated foreign matter and dirt cause hot spots at this position of the photovoltaic module and threaten the safety of the module. Moreover, since the dust or debris on the photovoltaic module will be washed away by rain, it is equivalent to a natural cleaning of the upper surface of the photovoltaic module, which will not affect the appearance of the photovoltaic module and also improves the cleanliness of the photovoltaic module.

[0032] Therefore, due to the adoption of the frame 2 with an unobstructed upper surface in the photovoltaic module of the present application, the upper surface of the photovoltaic laminate 1 forms a full-screen light-receiving surface, and there is no need to worry about the risk of the upper surface of the photovoltaic module being blocked by dirt and foreign matter. The dirt on the surface of the photovoltaic module can be smoothly separated from the photovoltaic module under the washing of rain, greatly improving the power generation efficiency of the photovoltaic module; also due to the natural cleaning of rain, it not only avoids the influence of the dust covering the upper surface of the photovoltaic module on the power generation efficiency of the photovoltaic module, but also ensures the beauty of the product and saves the labor cost for cleaning the upper surface of the photovoltaic module.

[0033] In some embodiments, as shown in Figure 2 shown, a counterbore 11 is provided at the upper end of the mounting hole 12 so that the nut of the bolt 3 is hidden in the counterbore 11. After the bolt 3 is installed, the nut of the bolt 3 is flush with the upper surface of the photovoltaic laminate 1, avoiding rainwater and dust from accumulating on the nut in the counterbore 11. Herein, the counterbore 11 is a part of the mounting hole 12. The counterbore 11 may also be called a counter-sunk groove or a stepped hole.

[0034] In some embodiments, as shown in Figure 1 and Figure 7As shown, a protective gasket sleeve 7 is provided in the counterbore 11. The protective gasket sleeve 7 has a protective sleeve that abuts against the side wall of the counterbore 11 and a protective gasket that abuts against the step surface of the counterbore 11. The provision of the protective gasket sleeve 7 in the counterbore 11 prevents rainwater and dust from entering the photovoltaic laminate 1. The inner diameter of the protective sleeve is the same as the outer diameter of the nut of the bolt 3, and the aperture of the protective gasket is the same as the diameter of the screw of the bolt 3; the outer diameter of the protective sleeve and the protective gasket has an interference fit with the inner diameter of the mounting hole 12 of the photovoltaic laminate 1 to ensure the reliability of the seal.

[0035] In some embodiments, referring to Figure 1 and Figure 7 as shown, the thickness of the protective gasket sleeve 7 is 0.5 mm - 2 mm.

[0036] In some embodiments, referring to Figure 1 and Figure 7 as shown, the protective gasket sleeve 7 is made of rubber or silica gel. Specifically, a double connection method of bolt 3 connection and silica gel / tape bonding is adopted to make the mechanical load performance of the photovoltaic module more excellent.

[0037] In some embodiments, referring to Figure 2 as shown, the depth of the counterbore 11 is less than half of the thickness of the photovoltaic laminate 1.

[0038] In some embodiments, an adhesive layer 6 for bonding the photovoltaic laminate 1 is laid on the support plane 24.

[0039] In some embodiments, referring to Figure 1 , Figure 5 , Figure 6 and Figure 7 as shown, the adhesive layer 6 is silica gel and / or double-sided tape. When double-sided tape and silica gel are used in combination as the adhesive layer 6, it can effectively prevent silica gel from overflowing.

[0040] In some embodiments, referring to Figure 8 as shown, the spacing of the mounting holes 12 is 50 mm - 200 mm.
