In development since 2009, SolarWindow is an energy-generating liquid veneer intended for new or retrofit architectural glass and flexible plastic surfaces. The patent-pending technology—an alternative to rooftop solar panels—utilizes windows as vertical power generators. SolarWindow modules are coated with tiny solar cells that form a network of arrays made of polymers, which include hydrogen and carbon elements. The energy produced by SolarWindow, intended for application on every window of a building, is unaffected by the angle of the sun. According to SolarWindow Technologies, installing these integrated windows could reduce a building’s total electricity bill by 30- to 50 percent. Currently, the Maryland-based company is looking for tall towers and skyscrapers for test applications.
