The Lawrence Berkeley National Laboratory and the US Department of Energy stated the following in their Sep. 2014 report "Tracking the Sun VII," authored by Galen Barbose, Samantha Weaver, and Naïm Darghouth, available at emp.lbl.gov:

Given the relatively high historical cost of PV, a key goal of these policies has been to encourage cost reductions over time through increased deployment. Key research and development efforts to drive cost reductions have also been led by the U.S. DOE's SunShot Initiative, which aims to reduce the cost of PV-generated electricity by about 75% between 2010 and 2020.

Following a period of relatively steady and sizeable declines, installed price reductions began to stall around 2005, as the supply chain and delivery infrastructure struggled to keep pace with rapidly expanding global demand. Beginning in 2008, however, global module prices began a steep downward trajectory, which has been the driving force behind the roughly 50% reduction in the installed price of PV from 2008 through 2013."
