California once again takes first place among states generating electricity from solar power this month. The Golden State produced almost 29% of the U.S. total of 25,240 thousand megawatt-hours, according to ChooseEnergy.com®’s September Solar Generation Report. The report analyzes the most recent data from the U.S. Energy Information Administration (EIA).

Following is a breakdown of the rest of the states (all shown in thousand megawatt-hours) using the EIA’s most recent data from June 2023:

U.S. solar generation of electricity experienced a small increase from May to June, rising only 2.1% nationwide. 17 states generated  less solar electricity in June than they did in May.

The following table shows solar generation by state for May and June, and the percentage change from month to month. States are listed in order of the amount of solar power they produced (including thermal), shown in thousand megawatt-hours. Alabama, Alaska, New Hampshire, South Dakota, and North Dakota are excluded from the table because they did not generate solar energy in May.
