In other words, U.S. solar seems poised for not just a record year but perhaps a blowout year. Last year, in contrast, solar set a new record with 7.3 gigawatts of total new photovoltaic capacity across residential, commercial, and utility scale installations.
“If actual additions ultimately reflect these plans, 2016 will be the first year in which utility-scale solar additions exceed additions from any other single energy source,” says EIA.
Justin Baca, vice president for markets and research at the Solar Energy Industries Association, told the Post that he agrees with EIA’s figures — though the industry group expresses them in direct current (DC) versus alternating current (AC), and so projects a total of 11.8 gigawatts of utility-scale solar photovoltaic installations, a number Baca calls “completely consistent” with EIA’s. On top of that, meanwhile, SEIA expects to see an additional 4 gigawatts of residential and commercial solar additions, for over 15 gigawatts in total, Baca said.
“Solar’s going to be the decisive leader in terms of capacity additions, for 2016,” Baca said.
The reason this is occurring, however, is not a simple reflection of solar’s growing popularity, or its widely agreed upon role in helping to battle climate change. Rather, it involves that darling of the industry, the 30 percent solar investment tax credit, which was extended late last year for five years, with a gradual phaseout.
Before its recent extension, the credit was set to phase out at the end of 2016. Accordingly, to make sure they captured the credit, a large number of installations had been planned to close by the end of this year.
“For the past eight years, the expectation had been that you were going to get your system done this year, otherwise the cost of the system in 2017 was going to be much higher,” Baca said. Now that the credit will actually not phase out, many of those already planned installations are going ahead on time. “Had the tax credits been extended earlier, people might have relaxed their timelines,” he said.
This logic means that 2017 won’t see as many installations as 2016 — but Baca thinks the industry will keep growing and that by 2019, will climb back to 2016’s high.
However, given the extension of the credit, it could be that 2016 actually ends a little lower than it would have otherwise, according to Nathan Serota, a solar industry analyst with Bloomberg New Energy Finance. But he concurs that there should still be a record year. “It’s going to be big,” Serota said. “The floor on 2016 will be over 9 gigawatts” including all types of solar installations, he said.
Serota says the tax credit extension means there could actually be only a slight difference between 2016 and 2017, if enough projects get pushed off til next year. “2016 is going to be a huge year, and then we’re going to continue to see big years over the next 5,” he said. Granted, solar could still face some headwinds, particularly from the competition offered by extremely low natural gas prices.
In the grand scheme, the tax credits for solar, as well as an extension of the production tax credit for wind, could serve as a kind of “bridge” into an era in which the Obama administration’s Clean Power Plan is operating — or at least, so the current administration hopes. Granted, that depends on whether that plan survives its current legal challenges.
A recent report from the National Renewable Energy Laboratory found that due to the tax credit extensions, the U.S. will add 53 additional gigawatts of renewable energy capacity by the year 2020.
