The amount of new solar energy capacity in the U.S. doubled last year and may double again in 2011 because of government incentives, stronger demand and falling prices, a trade group said.
The total capacity of photovoltaic and solar thermal power systems that were installed last year reached 956 megawatts, compared with 441 megawatts added in 2009, according to a report released today by the Solar Energy Industries Association.
