A glass mechanism is arranged at the upper end of the upper EVA film 2. The glass mechanism is arranged inside the sealing sleeve 6. The glass mechanism includes a glass panel 4. The two sides of one end of the glass panel 4 close to the EVA film 2 protrude, and the middle of the glass panel 4 is spaced from the end face of the EVA film 2. A glass column 5 is fixedly connected to the lower end of the glass panel 4. The lower end of the glass column 5 abuts against the end face of the EVA film 2. A through hole 17 is opened at the upper end of the aluminum alloy frame 7, and a through hole 15 is opened at the lower end of the aluminum alloy frame 7. The through hole 17 and the through hole 15 are in communication. A filtering mechanism is arranged at the inclined upper end of the aluminum alloy frame 7; the storage box 18 performs photoelectric conversion through the photovoltaic panel, and the electric energy is stored in the storage box 18. The photovoltaic panel is made by stacking the battery cells 1, the EVA films 2 and the TPT backplane 3 up and down to form the core part. The sealing sleeve 6 and the aluminum alloy frame 7 are sleeved on the periphery. The internal core part is wrapped and sealed by the sealing sleeve 6, and the aluminum alloy frame 7 on the outside provides a supporting and protecting function. Specifically, a glass panel 4 is arranged outside the upper EVA film 2. The glass panel 4 is low-iron and high-transmittance, suede tempered glass. The two sides of the lower end of the glass panel 4 protrude and are erected on the upper end face of the EVA film 2, so that a space is formed inside the glass panel 4, and a gap is formed between the lower end face inside the glass panel 4 and the upper end face of the EVA film 2. A through hole 17 is opened at the upper end of the aluminum alloy frame 7, and a through hole 15 is opened at the lower end of the aluminum alloy frame 7. When used outdoors, air circulation is achieved between the through hole 17 and the through hole 15 at the upper and lower ends, reducing the heat on the surfaces of the EVA film 2 and the battery cells 1 and improving the overall use efficiency.
