7.3 Gigawatts of new U.S. solar in 2015

The U.S. solar industry installed 7,286 megawatts (MW) of solar photovoltaics (PV) in 2015, according to GTM Research and the Solar Energy Industries Association (SEIA). For the first time ever, solar beat out natural gas capacity additions, with solar supplying 30% of all new electric generating capacity in the U.S. in 2015. Led by California, North Carolina, Nevada, Massachusetts and New York, the U.S. solar market experienced a year-over-year growth rate of 17%. Geographically, the market continues to diversify with13 states installing more than 100 MW each in 2015. States that made major solar strides include Utah, which jumped in ranking from 23rd to 7th place, and Georgia which moved from 16th to 8th in the nation. The utility-scale sector, the mainstay of the U.S. solar market, grew 6% and represented more than half of all solar PV installed in 2015. Cumulative U.S. solar PV installations have now topped 25 GW, up from just 2 GW in 2010.
