These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. Many facilities have recognized the advantages of on-site renewable energy. For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and create a significant difference between the unadjusted costs and the capacity-weighted average national costs, as observed from recent market experience. This paper looks at the buildings that report onsite generation of renewable energy, including their type, location, and ENERGY STAR scores—as well as how they have changed over the past decade.
