The U.S. installed 10.6 gigawatts (GW) of solar photovoltaic capacity in 2018, according to a new report from Wood Mackenzie Power & Renewables and the Solar Energy Industries Association (SEIA).
The SEIA's president and CEO, Abigail Ross Hopper, said the solar industry experienced "growing pains in 2018" that were caused, in large part, by the imposition of tariffs on solar cells and modules.
The SEIA said that, for the U.S., total installed photovoltaic capacity was expected to increase by 14 percent this year, with yearly installations hitting 15.8 GW in 2021.
The U.S. is now home to over 64 GW of installed capacity, which is enough to power more than 12 million homes.
