[0031] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0032] Reference below Figure 1-Figure 8 A photovoltaic assembly 100 according to an embodiment of the present invention is described.

[0033] like Figure 1 and Figure 2As shown, the photovoltaic module 100 according to the embodiment of the utility model includes: a front glass 10, a back glass 20 and a protective device 30, the back glass 20 is located on the back of the front glass 10, the back glass 20 is provided with an opening 21, at least part of the protective device 30 is arranged above the front glass 10, and at least part of the protective device 30 is located directly above the opening 21.

[0034] Specifically, the front glass and back glass of traditional photovoltaic modules can withstand hail with a diameter of 40 mm. Since the back glass needs to be provided with openings for connection with the junction box, the provision of the openings reduces the strength of the back glass, resulting in a decrease in the ability of the photovoltaic module to withstand hail. For example, a photovoltaic module that can withstand hail with a diameter of 40 mm without openings can withstand hail with a diameter of 35 mm after the openings are provided. In order to improve the anti-hail ability of photovoltaic modules to withstand hail with a diameter of 50 mm, it is generally necessary to increase the thickness of the front glass and back glass, but there are problems of overweight and high cost.

[0035] Therefore, the photovoltaic module 100 is provided with a protective device 30, which is arranged above the front glass 10 to prevent hail from hitting the front glass 10 and protect the weaker part of the photovoltaic module at the opening 21. Specifically, the protective device 30 is arranged just above the opening 21, and the protective device 30 can cover the opening 21 at the position corresponding to the opening 21, so that the strength of the photovoltaic module at the opening 21 can be strengthened, thereby improving the anti-hail ability of the photovoltaic module 100, so that the ability of the photovoltaic module 100 to withstand hail with a diameter of 50 mm can be met. In addition, the protective device 30 is arranged in the white grapefruit area in the middle of the photovoltaic module 100, and the width of the protective device 30 is set to be smaller than the width of the white glaze area, which can prevent the shading of the battery cells in the photovoltaic module 100. For example, the width of the protective device 30 can be set to 15 mm, the thickness can be set to 5 mm, and the width of the white glaze area can be set to 16 mm. The width of the protective device 30 can be adjusted for different photovoltaic modules 100.

[0036] Therefore, the provision of the protective device 30 in the photovoltaic module 100 can prevent the front glass 10 from being hit, and can also strengthen the strength of the photovoltaic module 100 corresponding to the opening 21, thereby improving the anti-hail capability of the photovoltaic module 100.

[0037] According to some embodiments of the present invention, Figure 1 As shown, the photovoltaic assembly 100 further includes: a frame 40 , which is disposed at the edges of the front glass 10 and the back glass 20 , and the protective device 30 is connected to the frame 40 .

[0038] The edges of the front glass 10 and the back glass 20 are installed in the frame 40, and the protective device 30 is fixedly connected to the frame 40, so that the connection of the protective device 30 can be ensured to be more stable.

[0039] According to some embodiments of the utility model, the protective device 30 includes: a protective member 31 and a fixing member 32, the protective member 31 includes: a protective body 311 and a fixing portion 312, the fixing portion 312 is respectively connected to both ends of the protective body 311, the protective body 311 is arranged above the front glass 10, and the protective body 311 is located directly above the opening 21, the fixing portion 312 is arranged on the frame 40, and the fixing member 32 is respectively connected to the fixing portion 312 and the frame 40.

[0040] Among them, the protective device 30 is mainly composed of a protective part 31 and a fixing part 32. The protective body 311 in the protective part 31 can play a role in protecting the photovoltaic module 100. The protective body 311 is arranged above the front glass 10 and is also located directly above the opening 21. It can prevent the front glass 10 corresponding to the opening 21 from being hit by hail, and can also strengthen the local strength of the photovoltaic module 100 corresponding to the opening 21.

[0041] In addition, the two ends of the protective body 311 are connected with fixing parts 312, and the fixing parts 312 at both ends of the protective body 311 are symmetrically arranged. The fixing parts 312 are fixedly connected to the frame 40 through fixing members 32, so that the protective member 31 can be connected to the frame 40 more stably and firmly.

[0042] According to the specific embodiment of the utility model, Figure 5 As shown, the fixing portion 312 includes: a first fixing section 313 and a second fixing section 314, the first fixing section 313 is connected to the end of the protective body 311, the first fixing section 313 corresponds to the outer wall of the frame 40, the second fixing section 314 is connected to the first fixing section 313, the second fixing section 314 is bent relative to the first fixing section 313, the second fixing section 314 corresponds to the bottom wall of the frame 40, and the fixing member 32 is arranged on the second fixing section 314.

[0043] Specifically, the first fixing section 313 in the fixing portion 312 is arranged corresponding to the outer side wall of the frame 40, which can increase the local strength of the frame 40 and further increase the connection strength between the fixing portion 312 and the frame 40. The second fixing section 314 is bent relative to the first fixing section 313, which can facilitate the connection between the second fixing section 314 and the bottom wall of the frame 40. In addition, the fixing member 32 is arranged in the second fixing section 314, which can facilitate the fixing member 32 to be fixedly connected to the frame 40 through the second fixing section 314.

[0044] According to some embodiments of the present invention, Figure 3-Figure 5As shown, the fixing portion 312 is provided with a first mounting hole 36 , the frame 40 is provided with a second mounting hole, the second mounting hole is arranged opposite to the first mounting hole 36 , the fixing member 32 is a fastener, and the fastener passes through the first mounting hole 36 and the second mounting hole.

[0045] When the fastener is a screw, the screw can be inserted into the first mounting hole 36 and the second mounting hole in sequence, and the fixing portion 312 can be fixed to the frame 40 by the screw, so that the protective member 31 can be fixedly connected to the frame 40 more stably and firmly.

[0046] According to another embodiment of the present invention, Figure 6-Figure 8 As shown, the fixing member 32 is a buckling member, which is buckled with the frame 40.

[0047] Among them, when the fixing member 32 is set as a snap-fitting member, the snap-fitting member can be snapped onto the bottom wall of the frame 40. In this way, punch-free installation can be achieved, and the fixed connection between the protective member 31 and the frame 40 can be facilitated, thereby shortening the time for the fixed connection between the protective member 31 and the frame 40, and improving the efficiency of the fixed connection between the protective member 31 and the frame 40.

[0048] According to the specific embodiment of the utility model, Figure 7 As shown, the fastening member includes: a base body 33, a rotating arm 34 and a fastening arm 35, the base body 33 is arranged on the fixing member 32, the rotating arm 34 is rotatably arranged on the base body 33, one end of the fastening arm 35 is rotatably arranged on the rotating arm 34, and the other end of the fastening arm 35 is fastened with the frame 40.

[0049] Among them, the snap-fitting part is mainly composed of a base body 33, a rotating arm 34 and a snap-fitting arm 35. The base body 33 can provide an installation space for the setting of the rotating arm 34 and the snap-fitting arm 35. The rotating arm 34 can rotate. A spring is arranged at the rotating arm 34 to adjust the magnitude of the force. Since one end of the snap-fitting arm 35 is connected to the rotating arm 34, when the other end of the snap-fitting arm 35 rotates, the clamping force of the other end of the snap-fitting arm 35 on the frame 40 can be adjusted, so that the connection between the snap-fitting part and the frame 40 can be made more stable and firm.

[0050] According to some embodiments of the present invention, Figure 5 and Figure 8 As shown, the protection device 30 further includes an elastic pad 50 , which is disposed on the inner surface of the protection member 31 facing the front glass 10 and the frame 40 .

[0051] Among them, the elastic pad 50 is arranged between the protective member 31 and the front glass 10. The protective member 31 contacts and cooperates with the front glass 10 through the elastic pad 50. The elastic pad 50 can protect the front glass 10 and prevent the protective member 31 from causing the front glass 10 to be cracked during the locking process.

[0052] According to some embodiments of the present invention, the protective member 31 is an aluminum profile, and the elastic pad 50 is a rubber pad.

[0053] Among them, the protective member 31 is set to be an aluminum profile, which has high strength and corrosion resistance, and can provide impact resistance and pressure resistance. The aluminum profile is relatively light compared to other materials and can also achieve lightweight design.

[0055] Among them, three openings 21 can be set, and the three openings 21 are evenly spaced in the width direction of the back glass 20. Correspondingly, the protective body 311 extends in the spacing direction of the three openings 21, and the protective body 311 can cover the three openings 21. In this way, the strength of the part of the photovoltaic component 100 corresponding to the position of the opening 21 can be increased, thereby improving the anti-hail ability of the photovoltaic component 100.

[0056] In addition, through experiments, it is verified that the conventional front glass 10 with a thickness of 2 mm and the back glass 20 with a thickness of 2 mm can withstand hail with a diameter of 35 mm, and by adding the protective device 30, they can withstand hail with a diameter of 40 mm. The front glass 10 with a thickness of 2 mm and the back glass 20 with a thickness of 2.8 mm can withstand hail with a diameter of 45 mm, and by adding the protective device 30, they can withstand hail with a diameter of 55 mm.
