September Solar Energy Generation by State Report

California once again takes first place among states generating electricity from solar power this month. The Golden State produced more than 30% of the U.S. total of 21,989 thousand megawatt-hours, according to ChooseEnergy.com®’s September Solar Report. The report is an analysis of 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) from the EIA’s most recent data from June 2022:

Top 10 states generating electricity from solar
