All data relevant to the reported results in this report can be found in the NREL Data Catalog. 2 Figure ES-1 (page vi) compares our Q1 2021 PV-only benchmarking results to the Q1 2020 National Renewable Energy Laboratory benchmarking analyses. 3. This report benchmarks installed costs for U. solar photovoltaic (PV) systems as of the first quarter of 2021 (Q1 2021). We use a bottom-up method, accounting for all system and project development costs incurred during installation to model the costs for residential, commercial, and. . Each year, the U. Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. These benchmarks help measure progress toward goals for reducing solar electricity costs. . DOE's Energy Storage Grand Challenge supports detailed cost and performance analysis for a variety of energy storage technologies to accelerate their development and deployment The U.
