Descriptions of 20 Watts ETFE Solar Panel, PCB PV Module

Coulee ETFE solar panels combine high-quality ETFE, UV-resistant EVA, and efficient solar cells. ETFE (Ethylene Tetrafluoroethylene) is highly durable and resistant to environmental elements making it far superior to PET or laminate solar panel construction. Our team manages the manufacturing and laminating process parameters to ensure each solar panel will perform in challenging outdoor environments.
