Solar technologies use the sun's energy to provide electricity, heat, light, hot water, and even cooling for homes, businesses, and industry. Learn more about solar energy technologies such as photovoltaic (solar electric) systems, concentrating solar power systems, passive solar heating and daylighting, solar hot water, and solar process heat and space cooling.
Solar energy research at NREL includes photovoltaics, solar radiation, solar systems integration, and solar thermal.
NREL's capabilities in photovoltaics (PV) range across fundamental and applied research and development, including theory and modeling, materials design and deposition, measurements and characterization, and reliability testing and engineering.
Optimal siting of solar energy systems requires knowledge of the solar resource characteristics at any given location. NREL's solar radiation research and data collection are performed at the Solar Radiation Research Laboratory. This unique research facility measures solar radiation and other meteorological data continuously and shares the information with government agencies, industry, academia, and international laboratories and agencies. These data are used for climate change studies, atmospheric research, renewable energy conversion system testing, and more.
NREL works with the solar industry to lower the cost of solar water heating systems. Laboratory researchers assist with prototype development of new polymer (plastic) systems through modeling and optimization, characterization of system performance, and accelerated testing of materials durability.
