The Solar Energy Industries Association (SEIA) released the 2009 U.S. Solar Industry Year in Review, finding 2009 to be another year of strong growth despite the economic recession. Overall U.S. solar electric capacity, including both photovoltaic and concentrating solar power installations, increased by 37 percent. This was driven primarily by strong demand in the residential and utility-scale markets, state and federal policy advances and declining technology prices. As a result, total solar industry revenue reached $4 billion, a 36 percent increase over 2008.  The solar industry contributed to the overall economy by adding 17,000 new jobs from coast to coast. The solar industry today employs 46,000 U.S. workers and supports an additional 33,000 jobs in other sectors.
