Frequently asked questions
What is the largest solar plant in the United States?
Edwards Airforce Base in Kern CA is the largest in the census at 1.3 GW nameplate, ahead of Double Back Diamond (788.2 MW).
How many utility-scale solar plants does PanelCensus track?
12,862 utility-scale sites totalling 245.8 GW of nameplate capacity, alongside 3,928,469 distributed (rooftop and commercial) installations. Compiled from USGS USPVDB, EIA-860/860M and BLM 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.
