U.S. Solar Market Insight

Share

Updated December 14, 2021 

The U.S. installed 5.4 gigawatts (GWdc) of solar PV capacity in Q3 2021 to reach 113.5 GWdc of total installed capacity, enough to power 21.8 million American homes. Residential solar installations exceeded 1 GWdc and more than 130,000 systems in a single quarter for the first time in the industry's history, while utility-scale solar installations set another third quarter record at 3.8 GWdc. Due to supply chain constraints and other factors, costs have continued to rise across all market segments, placing strain on near-term deployment. However, forecasts remain strong, including the potential impacts of the Build Back Better Act, which would increase solar deployment projections by 31% over the next five years.

Press Release

WASHINGTON, D.C. and HOUSTON, TX – For the second quarter in a row, trade policy uncertainty and supply chain constraints are driving solar price increases across all market segments, according to the US Solar Market Insight report released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, a Verisk business. The recently dismissed petitions for anti-dumping and countervailing duties on solar cells from Malaysia, Thailand, and Vietnam caused significant shipping disruptions for importers, which further exacerbated supply chain constraints. Logistical challenges and price increases in the solar supply chain will depress deployment over the next year, resulting in a 7.4 GW (25%) decrease in the forecast for 2022 compared to previous forecasts. (Keep reading)
