# Solar electricity generation

Net electricity generated from solar energy in the year, in terawatt hours: utility-scale photovoltaic and solar thermal plants of 1 megawatt or more, plus the U.S. Energy Information Administration's estimate of small-scale photovoltaic systems such as rooftop panels.

## Key facts

- Solar electricity generation in the United States was 388.82 TWh in 2025, according to the U.S. Energy Information Administration.
- California had the highest solar electricity generation of 51 states in 2025, at 90.1 TWh, and North Dakota the lowest, at 0 TWh. Source: the U.S. Energy Information Administration.
- Published for 52 places, with figures from 2014 to 2025.
- Figures last updated on 2026-10-11.

- Indicator id: `electricity_generation_solar`
- Unit: TWh
- Note: United States and its states only, from 2014, the first year of EIA's small-scale estimates. The state total in electricity generation leaves small-scale solar out, so solar divided by that total overstates its share.
