NREL is a national laboratory of the U.S. Department of Energy
1. The national benchmark applies an average weighted by 2016 installed capacities.
2. Non-union labor is used.
3. Economies of scale—driven by BOS, labor, related markups, and development cost—are
demonstrated.

As demonstrated in Figure 29, from 2010 to 2017 there was a 77% reduction in the utility-scale
(fixed-tilt) PV system cost benchmark, and an 80% reduction in the utility-scale (one-axis) PV
system cost benchmark. Approximately 71% and 64% of that reduction can be attributed to total
hardware costs (for fixed-tilt and one-axis systems respectively), as module prices dropped 86%
over that time period. An additional 10% / 11% can be attributed to labor, which dropped 74% /
78% over that time period, with the final 19% / 25% attribitubal to other soft costs, including PII,
sales tax, overhead, and net profit (for fixed-tilt and one-axis systems respectively).
Looking at this past year, from 2016 to 2017 there was a 29% reduction in the utility-scale
(fixed-tilt) PV system cost benchmark, and an 28% reduction in the utility-scale (one-axis) PV
system cost benchmark. The majority of that reduction can be attributed to the 46% reduction in
module factory gate price, and a 45% / 41% reduction in inverter factory gate price.
