Developers installed 85 percent more solar panels in the United States in the first quarter than a year earlier, led by strong growth in commercial projects and demand in New Jersey, according to the Solar Energy Industries Association. Total U.S. installations were 506 megawatts in the quarter and may reach 3,300 megawatts this year, about 11 percent of the 2012 global market, the Washington-based trade group said Wednesday.
