In the past three years, the South Atlantic region of the United States installed more new utility-scale solar photovoltaic (PV) capacity than any other region of the country. States in the South Atlantic region installed 2.2 gigawatts (GW) of new solar capacity in 2019, more than double the 1.0 GW installed in California, which had the second-highest new solar capacity additions. Despite being home to the strong sun states of Arizona, New Mexico, and Nevada, at 0.9 GW, less solar capacity was installed in the rest of the West region in 2019 than in either the South Atlantic or in California.
