SEIA Sees Solar Industry Surging 43%
March 16, 2021
U.S. solar industry grew 43% and installed a record 19.2 gigawatts (GWdc)
of capacity in 2020, according to the U.S. Solar Market Insight 2020
Year-in-Review report, released by the Solar Energy Industries
Association (SEIA) and Wood Mackenzie.
The 8 GWdc of new installations in Q4 2020 marks the largest quarter in
U.S. solar history. For perspective, the U.S. solar market added 7.5
GWdc of new capacity in all of 2015. New capacity additions in 2020
represent a 43% increase from 2019 and breaks the U.S. solar market’s
previous record of 15.1 GWdc set in 2016.
California, Texas and Florida are the top three states for annual solar
capacity additions for the second straight year, and Virginia joins them
as a fourth state installing over 1 GWdc of solar PV. In 2020, 27 states
installed over 100 MWdc of new solar capacity, a new record.
Non-residential installations declined 4% from 2019, with 2 GW installed. The pandemic impacted this segment through delayed project interconnections and prolonged development timelines.
There was a historic 6.3 GWdc of utility-scale projects installed in Q4 2020, bringing the annual total just shy of 14 GWdc.
A total of 5 GWdc of new utility solar power purchase agreements were announced in Q4 2020, bringing the volume of project announcements in 2020 to 30.6 GWdc and the full utility-scale contracted pipeline to 69 GWdc.
The 2-year extension of the ITC in the final days of 2020 has led to a 17% increase in deployment in our 2021 – 2025 forecast.
