Solar power capacity additions in the second quarter of 2021 dipped compared to the year-ago period as developers encountered supply-side headwinds. However, demand remained strong, with a robust pipeline of projects totaling 17,428 MW under construction.
Developers put into service 1,968 MW of utility-scale solar power capacity from April to June, according to newly compiled S&P Global Market Intelligence data. That is 31% less than the amount installed in the first quarter, when 2,836 MW went into service. In the first half of 2021, 4,804 MW of solar power went online, a 15.1% increase from the year-ago period and nearly halfway to the 10-GW total from all of 2020.
The U.S. now has 53,792 MW of total solar power capacity, a figure that excludes distributed generation.
Typically the second and third quarters are the slowest for solar power capacity additions. But the second quarter of 2021 saw fewer capacity additions than the year-ago period, when 2,104 MW was connected to U.S. power grids. Developersin 2021 have been hit with supply chain constraints and rising prices.
