General Motors Electric Vehicle Solar Charging Station

Ever seen a solar panel that followed the sun’s movement? Neither have we. But that’s not stopping General Motors from installing a Tracking Solar Tree — pretty much a giant solar panel on an axis — at its Milford Proving Grounds.

What makes the Tracking Solar Tree even more intriguing is the fact that it contains a SunCharge electric vehicle charging station at its trunk, permitting the entire structure to produce up to 30,000 kilowatt hours a year and provide enough solar energy to charge six electric vehicles per day.
