Low cost module and mounting systems developed through Evergreen Solar´s PVMaT program

Under a PVMaT subcontract designed to lower photovoltaic module and systems costs, the authors have developed a novel backskin material to replace the more conventionally used Tedlar laminate. This backskin material allows for a frameless module construction and innovative mounting methods. This new backskin material shows an unusual capability to bond with metals, glass and other polymers. The material obviates the need for any other edge seal, and a completely formed module can be made directly in the laminator. A number of performance and reliability tests have been performed on modules made this way with very positive results. The new backskin, frameless module and innovative mounting method together result in estimated savings of $0.50/Watt
