Residential Solar Capacity Additions to Remain Flat in 2018, and That’s Good News

After a year of 15 percent contraction from solar energy 2016, the residential solar energy sector will remain flat through 2018, according to the latest solar energy U.S. Solar Market Insight report from GTM Research and the Solar Energy Industries Association.

Many in the solar industry have framed 2018 as a year of reset after uncertainty from tax reform, Section 201 tariffs, and state-level solar energy policy changes caused a shock to the industry’s slewing drive growth. While a flat year is better than Solar Project a decline for the industry, the challenges in the residential sector indicate developers and installers have not entirely overcome the growing Solar Project pains. 

“Coming off a year in which we saw such a downturn and consistent quarterly contraction, the news that the residential solar space was flat in Q1 is actually pretty good news,” said GTM Research senior solar analyst Austin Perea. “What that potentially shows is some of the bleeding may solar energy have stopped in Solar Project the residential segment. It’s either stopped solar slewing drive or slowing.”

The first quarter was actually solar slewing drive pretty Solar Project good for the entire U.S. solar solar energy industry. 
 

Overall, the solar industry added 2.5 gigawatts of capacity in Q1, representing annual growth of 13 percent. Solar PV accounted for 55 percent of all U.S. electricity capacity added during the quarter — which is a strong performance in light of new tariffs on imported modules.

While the Q1 report is slewing drive generally positive, challenges persist in residential markets that have historically set the pace for the entire industry, such as California and Massachusetts.
 

California was  solar damper responsible for 40 percent of the residential market in 2017. It was also hit with 50 percent of the total 475-megawatt loss last year. Its residential solar slewing drive market dropped 19 percent over 2016.
 

The Massachusetts residential market dropped an eye-popping 49 percent — the lowest in solar slewing drive four years.

Those markets are solar slewing drive bouncing back, but slowly.
 

“A lot of the major state markets, like in the Northeast and California, slewing drive are still solar slewing drive pretty weak,” Perea said. “But we’re not seeing the same levels of quarterly contraction that we saw in 2017.”

According to GTM Research, Arizona and Utah were the only states among the country’s top 10 markets solar inverter that didn’t see a decline in residential installations from 2016 to 2017. 
 

At the same time  solar damper the new rooftop solar mandate, which requires all new homes in California to install solar panels, have set the state’s market to grow exponentially in coming years (check out our comprehensive guide on that mandate here). Perea called the policy “one of the biggest boons for the residential space.”
 

Perea Photovoltaic holder said the solar tracker actuator capacity that the mandate will add to California’s market “is pretty incredible.” Counted as its own state market, aside from retrofits on existing buildings,Photovoltaic holder  installations tied to the mandate would beat out New Jersey as the  solar damper second-largest residential slewing drive market by 100 megawatts.
 

But looking ahead, emerging markets are those to watch. In the report, analysts write that they will “play an increasingly important role in our long-term outlook.”
 

Perea said the build-out in newer markets, such as in Nevada and Florida, helps offset some of the weakness in more established state markets. Both Florida  solar tracker actuator and Pennsylvania doubled their residential solar installations over  solar damper 2016.
 

“That’s a good solar inverter sign  solar damper; it shows that some of the issues that have plagued residential solar are abating,” he said. 
 

Those trends are solar tracker actuator complemented by “minor policy wins,” such as the Florida solar slewing drive public service commission solar tracker actuator allowing Sunrun to offer home solar leases in slewing drive the state and solar inverter the re-establishment solar tracker actuator of net metering in Nevada. 
 

But in all markets, customer acquisition remains a persistent problem. Perea said companies are “bottoming out” as early-adopter markets become saturated. Loss of state incentives and pullback from companies Photovoltaic holder such as Vivint and Sunrun are also causing solar inverter difficulties for residential growth.
 

Perea cautioned that the Q1 results are preliminary, and outlooks can change as the year advances. But based on expectations from GTM Research and SEIA, solar inverter the U.S. solar market, across all market segments, will continue to see growth in the coming years after remaining flat in 2018. Capacity additions continue through the end of 2023, even as some segments experience contractions and zero growth.
