DOE Solar Energy Technologies Office
The Solar Energy Technologies Office (SETO) is an office within the United States Department of Energy focused on accelerating development and deployment of solar energy technologies. SETO funds research, development, demonstration, and commercialization activities across photovoltaics, concentrating solar-thermal power, grid integration, and manufacturing. It engages with national laboratories, universities, industry consortia, state agencies, and non-profit organizations to advance cost reduction, performance improvements, and equitable access to solar energy.
SETO traces institutional lineage to early federal energy efforts such as the Federal Energy Administration, the Energy Research and Development Administration, and foundational programs of the United States Department of Energy established under President Jimmy Carter. Over decades, policy milestones including the Energy Policy Act of 1992, the Energy Independence and Security Act of 2007, and executive directives during administrations of George W. Bush, Barack Obama, Donald Trump, and Joe Biden shaped funding priorities and program structure. The office has coordinated with National Renewable Energy Laboratory, Sandia National Laboratories, Lawrence Berkeley National Laboratory, and academic programs at institutions like Massachusetts Institute of Technology, Stanford University, University of California, Berkeley, and Georgia Institute of Technology. SETO’s initiatives have responded to industry shifts driven by multinational corporations such as First Solar, SunPower Corporation, Enphase Energy, Tesla, Inc., and supply chain developments involving Longi Green Energy Technology Co., Ltd. and Trina Solar.
SETO’s mission aligns with directives from the United States Department of Energy leadership and federal statutes to reduce levelized cost of electricity, improve reliability, and broaden access to solar technologies. Core objectives include supporting photovoltaic efficiency gains through collaborations with IEEE-affiliated research groups, advancing concentrated solar power systems used in projects influenced by standards from American Society of Mechanical Engineers, and integrating solar into transmission planning guided by the Federal Energy Regulatory Commission. The office aims to accelerate commercialization pathways utilized by partners like National Science Foundation grantees, promote workforce development in programs linked to the Department of Labor, and enable state-level deployment in coordination with agencies such as the Environmental Protection Agency and Federal Highway Administration.
SETO administers competitive funding opportunities, prize competitions, technology incubators, and demonstration projects. Signature initiatives have included the Solar Energy Innovation Network, tech-to-market programs interfacing with Small Business Administration resources, and prize challenges similar to those run by the XPRIZE Foundation. Demonstration efforts have linked with large-scale utility projects led by entities like Pacific Gas and Electric Company, Southern Company, Duke Energy, and municipal utilities in cities such as Los Angeles and Austin, Texas. International collaborations have engaged multilateral organizations including the International Renewable Energy Agency and the World Bank while coordinating with foreign ministries such as China National Energy Administration counterparts and the European Commission energy directorates.
SETO allocates funds through competitive solicitations, cooperative agreements, and subawards to national laboratories, universities, small businesses via Small Business Innovation Research and Small Business Technology Transfer programs, and nonprofit partners such as Clean Energy States Alliance. Funding mechanisms interface with federal budget processes overseen by the United States Congress and appropriations committees, and are influenced by legislation like the Inflation Reduction Act of 2022. Grant recipients have included academic teams at University of Colorado Boulder, North Carolina State University, and University of Michigan as well as corporations ranging from startups incubated at Fraunhofer Center for Sustainable Energy partners to established manufacturers like First Solar.
R&D priorities cover photovoltaic materials and devices, solar manufacturing, system integration, energy storage coupling, and resilience. Materials research spans thin-film technologies studied at National Renewable Energy Laboratory and perovskite research pursued at Harvard University and California Institute of Technology. Device engineering engages semiconductor expertise shared with Intel Corporation-adjacent research and standards bodies such as SEMATECH. Grid integration work intersects with transmission research at Pacific Northwest National Laboratory and resilience planning linked to Department of Homeland Security efforts. Energy storage coupling is coordinated with battery research funded by Advanced Research Projects Agency-Energy and partnerships with companies like CATL and LG Chem.
SETO leverages partnerships across the innovation ecosystem: national laboratories (including Argonne National Laboratory), academia (e.g., University of California, San Diego), industry consortia (such as SEIA-aligned groups), state energy offices (for example California Energy Commission), workforce organizations like Solar Energy International, utilities including NextEra Energy and Iberdrola, and international research centers such as Fraunhofer ISE. Collaborations with standards organizations such as Underwriters Laboratories and International Electrotechnical Commission facilitate codes and standards development. The office engages venture capital networks, corporate R&D arms of firms like General Electric and Siemens, and non-governmental advocacy groups such as Natural Resources Defense Council.
SETO measures progress through metrics including cost reductions in levelized cost of energy, efficiency improvements in modules and systems, deployment volumes in megawatts and gigawatts, job creation statistics tracked with the Bureau of Labor Statistics, and emissions reductions calculated in coordination with Environmental Protection Agency inventories. Independent evaluations have drawn on data from Lawrence Berkeley National Laboratory studies, industry reporting by BloombergNEF, and modeling from the National Renewable Energy Laboratory to assess contributions to renewable portfolio standards in states like California and New York. Results inform congressional oversight hearings and executive reviews involving committees such as the House Committee on Energy and Commerce and the Senate Committee on Energy and Natural Resources.
