U.S. Solar Surged 17% in 2015 Led by Demand for Rooftop Power

  • Developers added 7.3 gigawatts, surpassing new natural gas
  • California, North Carolina continue to lead, trade group says

Solar power developers added a record 7.3 gigawatts of capacity in the U.S. last year, up 17 percent from 2014 and surpassing natural gas installations for the first time.

Residential installations climbed 66 percent, the fastest-growing segment, and accounted for 29 percent of all photovoltaic systems, according to a report Monday from GTM Research and the Washington-based Solar Energy Industries Association. California, North Carolina and Nevada were again the top three solar states. Utah jumped from 23rd to 7th, while New Jersey slipped to 10th from sixth.
