A Decade of Solar

Raise a glass to a successful 2019 in solar, as the final Q3 of the calendar year has proven to be the most successful one of the decade. Heck, with a statement like that, it might be better to raise the entire bottle! 

But first, a quick overview of how the story played out.

After steady double-digit-percent increases in the early years of this past decade, U.S. residential solar experienced growing pains from 2016-17, as that nation’s presidential leaders changed from being more coal than solar-friendly, diverting subsidies towards fossil fuels over renewables. Tariffs on Photovoltaic hardware loomed ominously on the horizon and national installers pulled back in critical solar territories such as California and the Northeast. It seemed that the solar market was receding from its peak-installation crest, reaching its high-water-mark of annual installed capacity of 687 MWdc, set in Q1 2016. That all changed in Q3 2019, however, as the Federal Investment Tax Credit (ITC) ticked out its final remaining months of a 30 percent payback, before beginning to phase out according to the following schedule:

Enacted in 2006 the ITC offsets the cost of solar for residential consumers by 30 percent. Experts estimate the subsidy has helped the solar industry grow more than 10,000% creating hundreds-of-thousands of jobs and generating billions in revenue. Next year’s phase-out of the ITC has inspired many home-owners on the fence about installing solar to seize upon the financial opportunity. The result was that in Q3 2019 consumers installed 712 MWdc of solar.

Now, as the solar market readies to step into a new decade and matures out of its early product adopters in many North American states, a new report by Solar Energy Industries and WoodMackenzie Power and Renewables gives a glimpse into what the future of solar might look like. 

California Love

When it comes to being a national leader for residential solar installations, Tupac’s California Love lyrics are fitting:

“Now let me welcome everybody to the Wild Wild West

A state that’s untouchable like Eliot Ness…we in that Sunshine state….”

Well, you get the idea. 

The point is that California was and is projected to remain the state leading the residential solar market charge. In the big Q3 solar market performance of 2019, California accounted for approximately 41% of the nation’s installs which is roughly the equivalent of 300 MW.
