[0028] Embodiment 1

[0029] Please refer to Figures 1 to 3, an embodiment of the present utility model discloses a solar photovoltaic module capable of resisting strong winds. The solar photovoltaic module of this solution includes a photovoltaic panel main body 1, and the photovoltaic panel main body 1 includes a lower bottom plate 11, battery cells 12, and an upper glass cover plate 13. The battery cells 12 are arranged on the lower bottom plate 11, and the upper glass cover plate 13 covers the battery cells 12. An air passing through hole 14 penetrating the upper glass cover plate 13, the battery cells 12, and the lower bottom plate 11 is provided on the photovoltaic panel main body 1. With such a design, the air passing through hole 14 provided in the solar photovoltaic module can reduce the wind pressure in the following aspects: a. Changing the flow path and speed of the wind, reducing the direct impact of the wind on the surface of the solar photovoltaic module, thereby reducing the pressure in the positive pressure area; b. The air passing through hole 14 allows the wind to pass through, reducing the overall wind resistance; c. The design of the air passing through hole 14 can accelerate the airflow on the leeward side of the solar photovoltaic module, thereby reducing the negative pressure on the leeward side and reducing the pressure difference on the surface of the entire solar photovoltaic module; d. After the wind impacts the solar photovoltaic module, it flows out through the air passing through hole 14, reducing the accumulation and impact of the wind, and thus reducing the wind pressure. In summary, by providing the air passing through hole 14, the wind resistance effect of the solar photovoltaic module can be effectively improved.

[0030] Furthermore, considering that it is difficult to process through holes in the battery cells 12, preferably, the battery cells 12 are multiple, and at least two adjacent battery cells 12 are spaced apart to form an avoidance space, and the air passing through hole 14 penetrates the avoidance space. It can be understood that in other embodiments, avoidance through holes can also be directly opened in the battery cells 12 according to actual needs, and no limitation is imposed here.

[0031] Preferably, there are multiple air passing through holes 14, and the multiple air passing through holes 14 are spaced apart on the photovoltaic panel main body 1, so that the solar photovoltaic panel module has a better wind resistance effect.

[0032] Among them, the air passing through hole 14 can be a square hole or a circular hole, and no limitation is imposed here. In this embodiment, the air passing through hole 14 is taken as an example of a square hole.

[0033] In some embodiments, in order to fix the lower bottom plate 11, the upper glass cover plate 13, and the battery cells 12, the battery cells 12 are bonded to the lower bottom plate 11 and the upper glass cover plate 13 on the battery cells 12 through EVA 15. Specifically, a sheet of EVA 15 is stacked between the battery cells 12 and the lower bottom plate 11 and between the battery cells 12 and the upper glass cover plate 13, and then the solar photovoltaic panel module is placed in a laminator, and through vacuum pumping and heating, the EVA 15 is melted and the various layers of materials are firmly bonded together.

[0034] In some embodiments, in order to increase the structural strength of the solar photovoltaic module, the solar photovoltaic module further includes an inner frame 2. The inner frame 2 is disposed around the inner wall surface of the air passing through hole 14. A first installation groove is provided on the outer periphery of the inner frame 2. The inner peripheral edge of the photovoltaic panel main body 1 that encloses to form the air passing through hole 14 is embedded in the first installation groove.

[0035] Furthermore, in order to facilitate the encapsulation of the photovoltaic panel main body 1 by the inner frame 2, the inner frame 2 includes a first installation plate 21 and a second installation plate 22. A part of the first installation plate 21 is located outside the air passing through hole 14 and another part passes through the air passing through hole 14. The second installation plate 22 is connected to the first installation plate 21. The first installation plate 21 and the second installation plate 22 jointly enclose to form the first installation groove. By adopting such a design method, the first installation plate 21 can be first passed through the air passing through hole 14, and then the second installation plate 22 and the first installation plate 21 can be fixed, so as to realize the installation and fixation of the inner frame 2 on the photovoltaic panel main body 1.

[0036] Even further, the first installation plate 21 includes a horizontal plate 211 and a vertical plate 212. One end of the vertical plate 212 is perpendicularly connected to the end of the horizontal plate 211, and the second installation plate 22 is perpendicularly connected to the other end of the vertical plate 212.

[0037] In some embodiments, in order to improve the sealing performance between the photovoltaic panel main body 1 and the inner frame 2, the solar photovoltaic module further includes an inner seal 3. The inner seal 3 is disposed between the inner frame 2 and the photovoltaic panel main body 1.

[0038] Furthermore, the inner seal 3 includes a sealant 31 located between the first installation plate 21 and the photovoltaic panel main body 1 and a sealing silica gel ring 32 located between the second installation plate 22 and the photovoltaic panel main body 1. By adopting such a design method, during installation, the sealing silica gel ring 32 is first installed between the second installation plate 22 and the photovoltaic panel main body 1, and then the gap between the first installation plate 21 and the photovoltaic panel main body 1 is filled with the sealant 31, which can improve the adaptability of the inner seal 3 in the gap between the photovoltaic panel main body 1 and the inner frame 2, thereby further improving the sealing performance between the photovoltaic panel main body 1 and the inner frame 2.

[0039] In some embodiments, in order to increase the structural strength of the solar photovoltaic module, the solar photovoltaic module further includes an outer frame 4. The outer frame 4 is disposed around the outer periphery of the photovoltaic panel main body 1. A second installation groove is provided on the inner periphery of the outer frame 4. The outer peripheral edge of the photovoltaic panel main body 1 is embedded in the second installation groove.

[0040] Furthermore, in order to improve the sealing performance between the photovoltaic panel main body 1 and the outer frame 4, the solar photovoltaic module further includes an outer sealing ring. The outer sealing ring is disposed between the outer frame 4 and the photovoltaic panel main body 1.

[0041] A solar photovoltaic module capable of resisting strong winds provided by the present utility model comprises a photovoltaic panel main body 1.

The battery cells 12 are arranged on the lower bottom plate 11, and the upper glass cover plate 13 covers the battery cells 12. An air passing through hole 14 penetrating through the upper glass cover plate 13, the battery cells 12 and the lower bottom plate 11 is provided on the photovoltaic panel main body 1. By adopting such a design method, the air passing through hole 14 of the solar photovoltaic module can reduce the wind pressure in the following aspects: a. changing the flow path and speed of the wind, reducing the direct impact of the wind on the surface of the solar photovoltaic module, thereby reducing the pressure in the positive pressure area; b. the air passing through hole 14 allows the wind to pass through, reducing the overall wind resistance; c. the design of the air passing through hole 14 can accelerate the air flow on the leeward side of the solar photovoltaic module, thereby reducing the negative pressure on the leeward side and reducing the pressure difference on the surface of the entire solar photovoltaic module; d. after the wind impacts the solar photovoltaic module, it flows out through the air passing through hole 14, reducing the accumulation and impact of the wind, and further reducing the wind pressure. In summary, by providing the air passing through hole 14, the wind resistance effect of the solar photovoltaic module can be effectively improved.
