[0038] In the prior art, in two adjacent photovoltaic modules 100, when the first frame 200 of the first photovoltaic module 110 and the second frame 400 of the second photovoltaic module 120 are connected to each other, the first frame 200 and the second frame 400 are likely to cover part of the upper surface of the laminate of the first photovoltaic module 110 and the second photovoltaic module 120, resulting in blocking of the light-receiving surface of the first photovoltaic module 110 and the second photovoltaic module 120, and the connecting piece between the first photovoltaic module 110 and the second photovoltaic module 120 is located in the middle instead of below the two, which further reduces the light-receiving surface per unit area of ​​the photovoltaic module connection system, resulting in a reduction in output power and affecting the power generation efficiency.

[0039] In order to solve the above problems, the present disclosure provides a photovoltaic assembly connection system.

[0040] like Figure 1 As shown in the figure, the photovoltaic module connection system mainly includes:

[0041] At least two photovoltaic modules 100, each photovoltaic module 100 includes a laminate, a first frame 200 assembled at a first edge of the laminate, and a second frame 400 assembled at a second edge of the laminate opposite to the first edge, the first frame 200 includes a first protective wall 201 and a first limiting portion 300 assembled at the first edge, the second frame 400 includes a second protective wall 401 and a second limiting portion 500 assembled at the second edge, and the first protective wall 201 and the second protective wall 401 are vertically arranged, and the first limiting portion 300 and the second limiting portion 500 are both located below the laminate;

[0042] The photovoltaic assembly 100 includes a first photovoltaic assembly 110 and a second photovoltaic assembly 120 . The first limiting portion 300 of the first photovoltaic assembly 110 and the second limiting portion 500 of the second photovoltaic assembly 120 are matched and connected in a limiting manner.

[0043] The first limiting portion 300 of the first frame 200 and the second limiting portion 500 of the second frame 400 for connecting the first photovoltaic component 110 and the second photovoltaic component 120 are hidden under the photovoltaic component 100 instead of between them, and will not block the light-receiving surface of the first photovoltaic component 110 and the second photovoltaic component 120. The first protective wall 201 of the first frame 200 and the second protective wall 401 of the second frame 400 are vertically arranged without occupying the larger space between the first photovoltaic component 110 and the second photovoltaic component 120, which can maximize the light-receiving surface, thereby improving the output power transmission and power generation efficiency of the photovoltaic component connection system.

[0044] In addition, the first limiting portion 300 of the first photovoltaic component 110 and the second limiting portion 500 of the second photovoltaic component 120 cooperate to limit the connection to form a lateral limit to prevent the photovoltaic component 100 from moving laterally and improve the stability of the photovoltaic component connection system.

[0045] In some embodiments, the first protective wall 201 of the first photovoltaic assembly 110 and the second protective wall 401 of the second photovoltaic assembly 120 abut against or form a gap. Figure 1 , Figure 4 , Figure 5 and Figure 6 The gap between the first protective wall 201 and the second protective wall 401 is small, and there is no other structure or component between the gaps. This design can increase the light receiving area per unit area of ​​the photovoltaic module connection system, which is conducive to installing more photovoltaic modules 100 and increasing the power generation. The first protective wall 201 and the second protective wall 401 can protect the side of the laminate, preventing the first photovoltaic module 110 and the second photovoltaic module 120 from bumping against the laminate during transportation and installation, causing damage to the laminate.

[0046] In the prior art, when adjacent photovoltaic modules are connected by frames and connectors, parts of the frames or connectors will inevitably cover the upper surface of the photovoltaic modules, blocking the light-receiving surface and affecting the appearance. However, the photovoltaic module connection system provided by the embodiment of the present disclosure has a first limit portion 300 and a second limit portion 500 of the frame hidden under the photovoltaic module laminate, and there is no frame blocking the laminate on the upper surface of the photovoltaic module 100. The laminates of multiple photovoltaic modules 100 are arranged in an arranged manner, so that the appearance of the photovoltaic module connection system is consistent and aesthetically pleasing.

[0047] Optionally, the first limiting portion 300 includes at least one water channel 301 with an opening facing upward, and the second limiting portion 500 includes at least one second limiting wall 501 extending downward, at least a portion of the second limiting wall 501 can extend into the water channel 301 and limit each other with the water channel 301, and the space formed between the water channel 301 and the second limiting wall 501 is connected to between the first protective wall 201 and the second protective wall 401. This design allows rainwater that penetrates from the gap between the first protective wall 201 and the second protective wall 401 to be discharged along the water channel 301 of the first limiting portion 300, and at least a portion of the second limiting wall 501 can extend into the water channel 301 and limit each other with the water channel 301, thereby preventing the first photovoltaic component 110 and the second photovoltaic component 120 from moving, and having strong stability. The water channel 301 can be set as one or more, such as Figure 4 , Figure 6 As shown, the number of water guide grooves 301 is 1. Figure 1 , Figure 5 As shown, the number of water guide grooves 301 is 2. When the water seepage is too large or the first water guide groove 310 is blocked, rainwater can flow into the second water guide groove 320 and be discharged smoothly. Such a design can ensure that the photovoltaic module connection system will not leak.

[0048] Optionally, the water guide groove 301 is formed by a water guide wall 3011, a bottom wall 3012 and a first limiting wall 3013, Figure 1 , Figure 4 , Figure 5 , Figure 6 The water guide wall 3011 is connected to the lower end of the first protective wall 201 and extends downward, the bottom wall 3012 is connected to the lower end of the water guide wall 3011 and extends below the second photovoltaic assembly 120, and the lower end of the first limiting wall 3013 is connected to the bottom wall 3012 and extends upward. The second limiting wall 501 can extend into the water guide groove 301 and limit each other with the first limiting wall 3013.

Without the first support arm 303, the second structural adhesive 620 is arranged on the top of the first corner key cavity 302, which can facilitate the stable connection between the laminate and the first frame 200 while saving materials.

[0053] Optionally, refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 The second limiting portion 500 also includes a supporting wall 502 for supporting the laminate, and is connected to the lower end of the second protective wall 401 , and the upper end of the second limiting wall 501 is connected to the supporting wall 502 .
