Request for Information (RFI) Technology and Market Potential of Photovoltaic-Thermal (PVT) Systems in the United States

The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) has issued a Request for Information (RFI) seeking input on the potential of photovoltaic-thermal (PVT) systems in the U.S. market. PVT systems combine traditional photovoltaic panels with thermal systems to capture waste heat from the panels, providing both electricity and thermal energy for applications like domestic hot water and space conditioning. This RFI aims to gather insights from stakeholders, including industry, research institutions, and state/local governments, to better understand the current state of PVT technology and the challenges to its wider adoption in the U.S. The DOE is particularly interested in learning about the business landscape, technological advancements, regulatory challenges, and consumer perspectives related to PVT systems. While PVT systems have seen greater uptake internationally, with countries like Korea, China, and Germany leading in installations, the U.S. has lagged behind with only 2 MWth of installed capacity compared to Korea's 138 MWth. By collecting stakeholder feedback, SETO hopes to identify the barriers preventing broader adoption domestically and potential opportunities for growth. The RFI outlines several key categories of interest for responses, including business challenges (e.g., market penetration, cost comparison to standalone PV systems), technological improvements (e.g., system complexity reduction), regulatory issues (e.g., permitting requirements), and consumer interest in PVT systems. SETO is particularly focused on understanding the financial and practical aspects of PVT systems, such as the cost-effectiveness, energy efficiency, and consumer demand compared to other solar solutions like PV + battery storage or traditional solar thermal systems. While this RFI does not offer financial support or incentives, responses may help shape future program development or funding opportunities related to PVT technology. Respondents are encouraged to share detailed, fact-based input by December 31, 2024, to assist SETO in assessing the current and future landscape of PVT systems in the U.S. The responses will not be made public but will contribute to SETO's strategy for advancing clean energy solutions aligned with the Inflation Reduction Act’s goals of promoting energy efficiency and reducing greenhouse gas emissions. Interested parties are invited to submit their feedback electronically to PVT-RFI@ee.doe.gov following the provided guidelines, which include specific formatting and content requirements.
