The United States installed more solar panels in 2012 than in any previous year, according to a new report, with residential use of solar power up 70 percent over 2011.
By the end of this year, homeowners, businesses and utility companies will have installed enough photovoltaic cells to produce 3.2 gigawatts (or GW) of electricity in the United States, up from 1.9 GW last year, according to the U.S. Solar Market Insight Report.
The report was produced by GTM Research Solar and a trade association, the Solar Energy Industries Association.
