About this technology
Overview
Glenn Research Center engineer Bernard Sater spent his spare time developing a solar concentrator that would use less silicon, making solar arrays cheaper. After retiring from NASA, Sater and his son formed Oberlin, Ohio-based GreenField Solar and, under a Space Act Agreement with Glenn, moved the technology toward commercialization. GreenField Solar now employs 30 people thanks to its NASA partnership.
