The U.S. Solar Photovoltaic Manufacturing Map shows only active manufacturing sites that contribute to the solar photovoltaic supply chain. It details their nameplate capacities, or the full amount of potential output at an existing facility, where known. This does not imply that these facilities produced the amount listed. The data for this map is gathered from public sources and through direct communication with producers. This data is subject to change and is for general informational purposes only. The Solar Energy Technologies Office (SETO) does not guarantee that the data is complete or free of error. If you would like to submit a comment, correction, or provide the information for a facility to be included on the map, contact us.

Key: ac = alternating current, CdTe = cadmium telluride, c-Si = crystalline silicon, dc = direct current, E-BOS = electrical balance-of-system, GW = gigawatt , HQ = headquarters, kt = kilotonne, MW = megawatt, S-BOS = structural balance-of-system, W = watt, and yr = year.
