405w 410w solar module backplane

Function, sealing, insulation, waterproof (usually TPT, TPE and other materials must be resistant to aging, most component manufacturers have a warranty of 25 years, tempered glass, aluminum alloy are generally no problem, the key is whether the backplane and silica gel can achieve Require.)

405w 410w solar module aluminum alloy

Protect the laminate, play a certain role in sealing and supporting

405w 410w solar module junction box

Protect the entire power generation system and play the role of a current transfer station. If the components are short-circuited, the junction box will automatically disconnect the short-circuited battery string to prevent the entire system from burning out. The most critical thing in the junction box is the selection of diodes. According to the different types of cells in the module, the corresponding diodes are also different.

405w 410w solar module silicone

The sealing function is used to seal the junction between the component and the aluminum alloy frame, and the component and the junction box. Some companies use double-sided adhesive strips and foam to replace silica gel. Silica gel is widely used in China. The process is simple, convenient, easy to operate, and the cost is very low.
