Residential Solar Peaks in Q3 of 2019

The U.S. residential solar power industry pulled off an all-time record for solar panel installations in the third quarter, according to new research from Wood Mackenzie and the Solar Energy Industries Association. And it happened with Northeast states — traditionally powerhouses in the sector — completely absent from a ranking of the top five state markets.

Solar in California still accounted for about 40 percent of all solar panel installations in Q3. But the Northeast's grip on residential solar panels loosened, with other regions rising. 

Record quarters in 15 states proved to be enough to break another record at the national level, with the U.S. adding 712 megawatts of new residential solar-powered systems, an increase of 8 percent from the same period last year.

Substantial growth occurred in mainstays like solar in California as well as in budding state markets such as Wyoming and Iowa.

While solar success spread throughout the U.S., though, the Northeast faced headwinds. Several states kept solar panel installation volumes steady, whereas in the past they'd shown growth. 

“Higher levels of saturation and the resulting steep customer-acquisition costs have slowed installation volumes since peak installation years, as the market grows past early-adopter consumers,” write WoodMac analysts of the region.

But cost of solar considerations may soon wane in importance as customers ponder going solar. Resiliency is driving significant demand in markets like California, where utility power shutoffs left millions without power for certain periods in 2019. 

The shutoffs, led most notoriously by Pacific Gas & Electric — the now-bankrupt utility criticized for poorly maintained equipment — spurred significant demand for solar panels as well as storage. Solar installers reported demand increases of three- to fivefold in the second half of this year, according to analysts, with storage attach rates jumping to new highs.

High-profile coverage of the California shutoffs and intensifying wildfires have meant an increase in solar-powered systems demand as far away as Texas. While analysts say it’s unclear if that bump will last, climate change — which has intensified wildfires in California and storms across the world — will continue to make resilience concerns top-of-mind for many consumers. 

"This is not going to go away," Sunnova CEO John Berger told GTM this fall. "It's not a one-time event, or two times. It’s not just the wildfires; it’s the hurricanes as well."

In California, demand related to power shutoffs coincides with a step-down in the federal Investment Tax Credit and the lead-in to implementation of updated building codes that will require rooftop solar panels on most new-build residential buildings. Taken together, those factors equate to a revitalization of the state's market, which is consistently the country's largest for residential solar panel installations.

More broadly, analysts forecast 8 to 18 percent growth in the nationwide residential market in the years through 2021, before the sector takes a dip and rebalances as the ITC dissolves in 2022 for customer-owned solar-powered systems; loans for solar are now the dominant form of financing for residential solar power customers.   

Beyond the residential solar energy market, the utility sector remains healthy, with a pipeline over 45 gigawatts, its largest ever. The non-residential market — encompassing community and distributed commercial solar panel installations — continues to struggle along, hindered by unfavorable policy changes in key state markets such as solar in California, Massachusetts and Minnesota.

Those problems are perhaps most acute in Massachusetts, where a cluster study encompassing 1 gigawatt of projects caused the state to bottom out with its lowest quarter of non-residential solar panel installations since 2011. While utility National Grid has already approved the resumption of more than 300 megawatts' worth of delayed projects, uncertainty prevails for the remainder of the solar power projects under review. But other Northeastern states will pick up the slack through 2022 as more favorable policies go into effect.
