The U.S. is poised to experience its first annual decline in solar-panel installations, as a drop in rooftop demand slows growth in the world’s second-biggest market.
Developers added a total of almost 2.4 gigawatts in the second quarter, putting the industry on pace to reach 12.4 gigawatts this year, according to a report Monday from GTM Research and the Solar Energy Industries Association. That’s down about 17 percent from a record 2016, and the research company expects another decline in 2018.
