Glass-free, frameless solar modules

Giga Solar high-efficiency crystalline-silicon, lightweight photovoltaic (PV) modules have successfully completed a series of environmental and mechanical stress tests at the CFV Solar Test Laboratory in Albuquerque, New Mexico. This work was part of the Boston-based Fraunhofer Center for Sustainable Energy Systems’ Plug-and-Play PV Project, funded by the Department of Energy’s SunShot Initiative. Giga Solar’s high-efficiency, crystalline-silicon, lightweight modules enable innovative, low-cost rooftop mounting methods. Because Giga Solar’s modules are glass-free and frameless, they can be flush-mounted directly onto the roof, avoiding the need for racking hardware, eliminating roof penetrations, and shortening the installation time. These benefits all contribute to lowering the cost of solar electricity. Testing was performed in two categories - environmental and mechanical. The environmental tests were a modified subset of the IEC-61215 protocol, a PV module performance standard used by the solar industry worldwide. Environmental testing included hail impact + 50 thermal cycles, 1000 hours of damp heat exposure and 500 thermal cycles. The mechanical tests, including various bending and localized pressure tests, were custom designed by Fraunhofer CSE to simulate the forces a lightweight module would encounter during transportation and installation.
