[0046] Furthermore, the limiting components are mutually cooperating pin holes 205 and limiting pins 400. Both the split box and the photovoltaic wing panel 100 have corresponding pin holes 205. In both the unfolded and retracted states, the limiting pins and pin holes cooperate to achieve limiting and fixation. Specifically, in the retracted state, the photovoltaic wing panels 100 are inserted into their slots, and the pin holes 205 around the photovoltaic wing panels 100 and the split box 200 are aligned before the limiting pins 400 are inserted, achieving limiting in the retracted state.

[0049] In this embodiment, the light-receiving plate has a variety of material options to meet different performance and weight requirements. For traditional single-glass modules, 3.2mm thick glass is selected to provide structural stability and protection; while double-glass modules use two layers of 2.0mm thick glass to enhance durability while maintaining light transmittance. In addition, thin glass with a thickness of only 0.8 to 1.0mm can be selected for lightweight photovoltaic modules to significantly reduce weight. Further, to pursue a more lightweight solution, the light-receiving plate is made of non-glass materials such as transparent PET (polyethylene terephthalate), transparent ABS (acrylonitrile-butadiene-styrene copolymer), or transparent PC (polycarbonate) film plate. These materials not only have excellent optical transparency, but also significantly reduce the self-weight of the module, making it easier to install and transport.

The weight of each split box 200 is controlled at about 2kg.

[0052] When folding is needed, the photovoltaic wing plate 100 is fixed upward into the sink 201, and is slid into the front and rear slots 202 and left and right slots 203, and one split box can carry 5 photovoltaic wing plates. A pin hole 109 is formed around the photovoltaic wing plate 100, and a corresponding pin hole 205 is formed around the split box. After sliding insertion, a limiting pin 400 is inserted to achieve fixation during folding.

[0053] When unfolding is needed, the photovoltaic wing plate 100 is slid to unfold in the front and rear slots 202 and left and right slots 203, and the pin hole 109 of the photovoltaic wing plate 100 is aligned with the pin hole 205 adjacent to the slot. After inserting the limiting pin 400, the fixation during unfolding is achieved.
