According to an article written by Chris Mooney, published in The Washington Post, the U.S. solar industry is on course for a new growth record in 2015, according to a new report that finds that solar photovoltaic installations now exceed 20 gigawatts in capacity and could surpass an unprecedented 7 gigawatts this year alone across all segments. A gigawatt is equivalent to 1 billion watts and can power some 164,000 homes
, according to the Solar Energy Industries Association (SEIA).
The new report, from GTM Research and SEIA, covers the second quarter of 2015, which set a new record for residential rooftop solar installations in particular, a category that saw 70 percent year-over-year growth. 473 megawatts of residential solar capacity were installed, or nearly half a gigawatt.
