The U.S. market for solar panels is likely to double in 2012, thanks to government policies and falling prices, although new tariffs on panels imported from China could contribute to slower growth in 2013, according to a new study.
U.S. developers are likely to install about 3,300 megawatts of solar panels this year, nearly double the amount installed in 2011, according to the study released Wednesday by the Solar Energy Industries Association and GTM Research. ...
Government subsidies, such as a federal tax credit equal to 30% of the cost of each system, and state and local incentives have been driving growing demand for solar. Better prices also have played a role.
