Abstract: A reflector is configured to reflect sunlight onto the double-sided power generation cell and mainly includes the reflector. The reflector is provided with a plurality of reflection regions. Each of the plurality of reflection regions is provided with a reflection protrusion having a different inclination angle. The double-sided power generation cell is obliquely disposed between two adjacent ones of the plurality of reflection regions. The reflection regions are capable of reflecting the sunlight onto a light-receiving side and a rear side of the double-sided power generation cell.

Abstract: A lock assembly includes a driving member, a locking member, and a latch. The driving member includes a connection end, and a driving end movable with respect to the connection end. The connection end is arranged on a fastener. The locking member is rotatably arranged on a carrier through a first rotation shaft. The driving end is rotatably connected to the locking member through a second rotation shaft. The locking member includes a hook. The latch is arranged on the fastener. The hook is capable of hooking the latch. The driving end is configured to capable of driving the hook to disengage from the latch, and driving the carrier to rotate with respect to the fastener, or the driving end is configured to drive the hook to hook the latch so that the carrier is secured to the fastener.

Abstract: Provided are a lightweight solar power generation panel and a method of preparing the same. The lightweight solar power generation panel comprises a substrate, an insulating layer, a cell layer and a support layer which are stacked in sequence; a material of the substrate comprises any one or a combination of at least two of polypropylene, polyvinyl chloride, polyethylene, polymethyl methacrylate, polycarbonate, polystyrene or an acrylonitrile-butadiene-styrene copolymer. The low-density substrate material is used in the lightweight solar power generation panel provided by the present disclosure so that the entire solar power generation panel is lighter and portable.
