US Solar Installs Fall to Their Lowest Level Since 2015, as Uncertainty Swirls and Prices Rise

A peek at third-quarter numbers in the latest U.S. Solar Market Insight report from GTM Research and SEIA.

America's solar industry had its toughest quarter in two years. 

Faced with political uncertainty, rising equipment prices, a slowdown in maturing markets, and a churn within residential installer rankings, deployments in the third quarter of the year are down on both a quarterly and annual basis. 

According to GTM Research and the Solar Energy Industries Association’s latest U.S. Solar Market Insight report, 2,031 megawatts of PV were installed in the U.S. in the third quarter of the year, resulting in the market’s smallest quarter in two years. (For historical context -- Q3 deployments were still 100 megawatts more than the entire year of installations in 2011.)

And even with the slowdown, solar PV added 25 percent of new capacity additions to America's grid in the first three quarters of the year -- coming in second to natural gas.

Two of the three market segments tracked by GTM Research and SEIA were down on the quarter and on the year; however, the non-residential segment was the lone standout.

The U.S. installed 481 megawatts of non-residential PV in the third quarter, representing growth of 22 percent year-over-year.

According to GTM Research solar analyst Austin Perea: “Regulatory demand pull-in was the primary market mover in Q3, as developers in California, Massachusetts and New York rushed to install projects to qualify for more favorable time-of-use periods, expiring incentive programs and grandfathering provisions. Meanwhile, non-residential solar in Minnesota experienced its largest quarter ever as the build-out of Xcel Energy’s robust community solar pipeline comes on-line.” 

With an unpredictable administration, a sweeping tax bill, and the threat of tariffs, it's been one of the busiest years in recent memory. These factors are all swirling around the industry, causing some doubts about the future.
