Solar Installation Grows As Cost Drops

摘要

The installed cost of solar PV power systems fell nearly 17% in 2010 from the year before and dropped an additional 11% in the first half of 2011, according to an annual report by the DOE's Lawrence Berkeley National Laboratory. The cost reductions are partially due to a continuing reduction in the price of PV modules, as well as an 18% drop in the cost of installation, marketing, overhead, and other non-module expenses between 2009 and 2010. The falling prices contributed to a rise in both nonresidential and utility-scale solar installations despite the economic climate, according to a recent report by the Solar Energy Industries Association trade group and GTM Research.
