Wood Mackenzie: U.S. will install 324GW of solar capacity in coming 10 years

March 16, 2021


Solar installations in the United States are expected to quadruple by 2030 thanks to the extension of a key industry subsidy late last year and booming demand for carbon-free power, an industry body said on Tuesday.

The sector will install 324 gigawatts (GW) of capacity over the next decade, more than three times the nearly 100 GW installed by 2020, the U.S. Solar Energy Industries Association (SEIA) said, citing a report issued jointly with Wood Mackenzie.

The outlook reflects both robust demand from utilities and corporations seeking to meet greenhouse gas reduction goals and declining costs for the technology that has buttressed the market for home solar installations.

Just 3% of U.S. electricity is generated from the sun, but SEIA hopes that will rise to 20% over the next decade.

Installations rose 43% last year to 19.2 GW, an annual record for the industry. Utility-scale projects, which account for most of the market, experienced only minor disruptions due to coronavirus pandemic-related shutdowns. Residential installations took a large hit in the second quarter due to the pandemic, but ended the year up 11% at a record 3.1 GW.

Late last year, Congress extended a 26% tax credit that helps reduce the cost of solar facilities as part of a package to provide coronavirus aid and fund the U.S. government. But SEIA said further tax incentives, the lifting of tariffs on overseas-made panels, and workforce training was necessary for the United States to cut enough greenhouse gas output to prevent the worst effects of climate change.
