This FOA is being issued by the DOE’s Office of Energy Efficiency and Renewable Energy Solar Energy Technologies Office. SETO supports solar energy R&D in three technology areas—photovoltaics, concentrating solar-thermal power, and systems integration—with the goal of improving the affordability, reliability, and performance of solar technologies on the grid. The SETO 2020 funding program seeks to advance R&D of solar technologies that reduce the cost of solar, increase the competitiveness of American manufacturing and businesses, and improve the reliability of the grid. These projects will advance R&D in PV, CSP, and energy management technologies, while also working to improve cybersecurity, expand solar to new applications like agricultural solar, integrate solar and storage, and utilize artificial intelligence to address research challenges.
