Installed Cost of Solar PV Continues Downward Trend
BERKELEY, Calif.— The installed cost of solar photovoltaic (PV) power systems in the United States fell 17% in 2010 and an additional 11% in the ﬁrst half of 2011, according to the annual PV cost tracking report released by the Department of Energy’s Lawrence Berkeley National Laboratory. These recent installed cost reductions are attributable, in part, to dramatic reductions in the price of PV modules that are making their way through to consumers, said Galen Barbose, a coauthor of the report. The report indicates that non-module costs—such as installation labor, marketing, overhead, inverters, and the balance of systems—also fell for residential and commercial PV systems by roughly 18% from 2009 to 2010. The “Tracking the Sun” series of studies has examined more than 115,000 residential, commercial and utility-sector PV systems installed between 1998 and 2010 across 42 states. This represents roughly 78% of all grid-connected PV capacity installed in the U.S. Some ﬁndings include: • Installed cost differs by region, ranging from $6.30/W to $8.40/W, depending on the state. Also, residential PV systems

installed on new homes had signiﬁcantly lower average installed costs than those installed on existing homes. • Among systems installed in 2010, those smaller than 2 kW averaged $9.80/W, while large commercial systems >1,000 kW averaged $5.20/W. Partial-year data for 2011 suggests that average costs declined even further in 2011. Large utility-sector systems installed in 2010 registered even lower costs, with a number of systems in the $3.00/W to $4.00/W range. • The average size of direct cash incentives provided through state and utility PV incentive programs has declined steadily since their peak in 2002.
