Foldable solar panel

Abstract

The adhesive film layer prevents the flexibility of the connecting conductor from being reduced after hardening, making the connecting conductor less likely to break in the bending section and improving durability. In addition, the isolation layer protects the connecting conductor, thereby reducing the safety risk of the conductor being exposed due to the outer sealing structure of the connecting conductor being broken through. [Solution] The foldable solar panel comprises a power generation layer (100) and two adhesive film layers (200) stacked on opposite sides of the power generation layer (100), the power generation layer (100) having at least two subordinate power generation panels (110) and connecting wires (120), the gap between two adjacent subordinate power generation panels (110) forms a bent section (2000), the two adjacent subordinate power generation panels (110) are electrically connected to each other via the connecting wires (120) passing through the bent section (2000), and an isolation layer (300) is provided between the connecting wires (120) and the adhesive film layer (200).
