EVA Film for solar cell solar module solar panel encapsulation

Solar EVA sheets play an important part in enhancing the durability and performance of solar panels. They enable the solar cells to ‘float’ between the glass and the backsheet, helping to soften shocks and vibrations and protecting the cells and their circuits.

The high-performance EVA sheets we supply are subject to rigorous quality testing and verification. Featuring products in a wide range of sizes and types, our portfolio of EVA films is a trusted source for many of the world’s largest photovoltaic module manufacturers.
