Photo voltaic (PV) systems in the US are getting to be better value, according to the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).
The average cost fell by more than 30 percent from 1998 to 2008, dropping four percent between 2007 and 2008.
"A goal of government incentive programs is to help drive the cost of PV systems lower. One purpose of this study is to provide reliable information about the costs of installed systems over time," says report co-author Ryan Wiser.
