The Solar Energy Technologies program focuses on developing cost-effective solar-energy technologies that have the greatest potential to benefit our nation and the world. Solar technologies diversify our energy supply, reduce our dependence on imported fuels, improve air quality, and offset greenhouse gas emissions. A growing solar industry also stimulates our economy by creating jobs in solar manufacturing and installation.
CSP systems use reflective materials that concentrate the sun's heat energy to drive a generator that produces electricity.
PV systems use semiconductor materials that convert sunlight directly to electricity.
Solar collectors absorb the sun's energy to provide low-temperature heat used directly for hot water or space heating for residential or commercial buildings.
