Historically, installed PV prices have declined an average of 5-7% per year from nearly $12/W in 1998, with particularly sharp reductions occurring since 2009. The recent price decline is, in large part, attributable to falling module prices, which fell by $2.1/W from 2008 through 2011, and have fallen further still in 2012. Non-module costs, such as installation labor, marketing, overhead, inverters, and the balance of systems for residential and commercial systems declined by roughly 30% from 1998 to 2011, but have not declined as rapidly as module prices in recent years.
