Frequently Asked Questions

Which states concentrate U.S. solar generation? ▼
The three largest solar producers account for 47% of reported U.S. solar generation in 2025 (California, Texas, and Florida). Variable resources cluster where resource and interconnection allow.
Which state generates the most solar energy? ▼
California leads with 90.1M MWh (2025), 38.0% of that state's own electricity mix.
What does solar operating capacity mean here? ▼
The 2026-05 EIA inventory reports 161.9K MW of net summer capacity across 7,404 plants in the categories used on this page. Capacity is not converted into generation on this page.
Where does RateWatt's solar data come from? ▼
Generation comes from EIA State Electricity Profiles (2025). Operating-plant capacity comes from the separate EIA operating-generator inventory (May 2026). Neither series is a retail-rate or customer-delivery measure.

Reading the solar numbers

Variable solar output clusters in a few high-resource states; own-mix share shows how much a state's grid leans on it when the resource is available.

  • California reports solar at 38.0% of its own mix; the top three states are 47% of the U.S. solar total. California profile
  • Compare solar capacity inventory against annual generation, rated MW is not MWh delivered. Operating fleet
  • LCOE assumptions and cited technology comparisons Read the guide

Generation mix is not the same as the electricity a state consumes; surplus is traded across the grid. See our methodology.

Where these figures come from

Generation and capacity are separate EIA series with separate vintages; neither is a retail-rate or customer-delivery measure.

Generation: U.S. Energy Information Administration (2025) · operating capacity inventory: 2026-05.
All federal data sources used on this page

Generation totals on this page come from EIA State Electricity Profiles for 2025; operating-plant capacity comes from the separate EIA operating-generator inventory (May 2026). No figure is typed in by an editor. State shares are generation_mwh for this source ÷ state total generation in the same profile year. Plant rows sum only units whose EIA energy-source/technology labels match this profile's allowlist.
