This week, a company called SoloPower unveiled a new line of flexible solar panels for commercial rooftops. SoloPower makes thin-film cells from a combination of copper, indium, gallium, and selenium which is then placed on a flexible foil.

The panels are lighter than glass-encased solar panels and can be installed much faster than other types of solar systems, SoloPower CEO Tim Harris said in a statement. The solar panels can be laminated onto rooftops and mounted on racks to tilt the panels. SoloPower is currently applying for a Department of Energy loan to increase its production abilities at their San Jose factory.
