Frequently asked questions
What is the largest solar plant in the United States?
Gemini Solar in Clark NV is the largest operating PV plant in the census at 690.0 MW AC nameplate, ahead of Danish Fields Solar, LLC (600.0 MW AC). Capacities are AC nameplate as reported to EIA; DC array size is shown where the source reports it.
How many utility-scale solar plants does PanelCensus track?
11,654 operating utility-scale PV sites totalling 152.8 GW of AC nameplate capacity (sites that report an AC figure), alongside 4,649,353 distributed (rooftop and commercial) installations. A further 335 plants (27.3 GW AC) are under construction and are not counted as operating. Compiled from USGS USPVDB and EIA-860/860M public records (cross-source deduplicated).
What counts as utility-scale?
Sites classified as utility-scale in the underlying sources — ground-mount plants selling power to the grid rather than offsetting on-site load, typically 1 MW and (usually far) above. Distributed rooftop and commercial systems are covered separately across the census.
Why isn't Ivanpah on the list?
This ranking covers photovoltaic (PV) plants. Ivanpah, Solana, Mojave Solar, Genesis and Crescent Dunes are concentrating solar-thermal plants — mirrors heating a fluid to drive a steam turbine — which EIA classifies as a separate technology, so they are excluded from PV rankings and totals.
