The U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) has issued a request for information (RFI) to gather input on the possible areas of technical research that would enable improvements in utility-scale photovoltaic (PV) systems to support PV plant service life of 50 years.

Reaching SETO’s goal of a levelized cost of electricity (LCOE) of $0.02/kWh by 2030 will require improvements to balance of system hardware design, DC-side fault detection capabilities, and PV plant maintenance strategies. SETO is interested in learning more from operations and maintenance (O&M) service providers, the solar component manufacturing and engineering, procurement, and construction industries, PV system owners, academia, research laboratories, government agencies, and other stakeholders. Areas of interest include available data and experiences regarding O&M costs and energy loss due to balance of system component degradation, and areas of research needed for more efficient O&M and increases to energy production throughout a 50-year PV system service life.
