Solar Research and Development Funding Programs

The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) funds solar energy research and development projects through competitive solicitations known as funding opportunities, as well as solar energy prizes and challenges.

Funding opportunities encompass at least one of six solar energy research areas: photovoltaics (PV), concentrating solar-thermal power (CSP), systems integration (SI), soft costs (SC), manufacturing and competitiveness (M&C), and solar workforce development (WF).

All active and completed funding programs are in the tables below. This data is subject to change and is for informational purposes only. SETO does not guarantee that the data is complete or free of error. If you have a question about any of the information below, email solar@ee.doe.gov.
