This bill prohibits federal agencies from using funds to procure solar panels manufactured or assembled by entities domiciled in or controlled by the People's Republic of China. The Office of Management and Budget, in consultation with the General Services Administration, must develop standards and guidelines for executive agencies to implement this ban across contracts, subcontracts, grants, and purchase card use. The Federal Acquisition Regulatory Council is also required to amend the Federal Acquisition Regulation to reflect this prohibition. An exemption waiver is available if an executive agency head certifies that a Chinese entity is the only viable source for the solar panels, provided the Secretaries of State and Homeland Security jointly approve the request. The Office of Management and Budget must then submit quarterly reports to appropriate congressional committees detailing these waiver requests and their outcomes. The legislation mandates a Comptroller General report on past federal procurement of solar panels from Chinese entities. Additionally, the Office of Management and Budget must contract for an independent study on the domestic solar panel market, its ability to keep pace with technological advancements, and the global supply chain and workforce involved in solar panel production, with findings to be submitted to Congress.
