US solar installations dipped 15% in the third quarter 2018 compared to the same period the year before, according to a report that Wood Mackenzie and the Solar Energy Industries Association released in mid-December.

However, a “strong project pipeline lies ahead,” the report said.

The report said the dip to 1,500 megawatts of solar capacity additions in Q3 2018 was fallout from the uncertainty that solar developers faced during most of 2017 while the US talked about rewriting its income tax laws and considered imposing tariffs on imported solar panels.

The third quarter was the third consecutive quarter in which new solar capacity additions were flat or marginally up.

Wood Mackenzie is projecting 11,100 megawatts of solar capacity additions in 2018, up from 10,600 megawatts in 2017. There were 14,626 megawatts of new solar installations in 2016. A strong rebound is expected in the fourth quarter 2018 when Wood Mackenzie expects 3,500 megawatts of new solar additions.
