The installed price of solar photovoltaic power systems in the U.S. fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The median installed price of residential and commercial PV systems completed in 2011 fell by roughly 11% to 14% from the year before, depending on system size. In California, prices fell by an additional 3% to 7% within the first six months of 2012.
These recent installed price reductions are attributable, in large part, to dramatic reductions in PV module prices, which have been falling precipitously since 2008, according to Berkeley Lab.
The report indicates that non-module costs – such as installation labor, marketing, overhead, inverters and the balance of system – have also fallen significantly over time.
