Solar EVA Film

Solar EVA Film

Its a most common encapsulation is with cross linkable EVA with the help of lamination machine. The cells are laminated between the films of EVA in a vacuum which is under compression. With the EVA the solar cells are floating between the glass & back sheet helping to softens shock & vibration therefore, protecting the solar cell & circuits.
