Median installed price of solar in the United States fell by 5-12 percent in 2015

The median installed price of solar in the US fell by 5-12% in 2015, with residential systems declining 5% and utility-scale projects falling 12%, according to two new studies from Lawrence Berkeley National Laboratory. The report attributes recent system price declines to reductions in hardware costs and 'solar soft' costs.
