Before solar road panels are installed on major highways, they need a significantly smaller road test to prove the concept.

Earlier this year, the Department of Energy awarded Solar Roadways a $750,000 grant, as reported by TreeHugger. That gives the company the funding to build a prototype about the size of a parking lot, which will provide researchers with a constant stream of data to understand how well the idea works in the field.
