Analysts from the U.S. Geological Survey and Lawrence Berkeley National Laboratory collaborated to develop and release the United States Large Scale Solar Photovoltaic Database (USPVDB). This effort built from the expertise gained while developing the regularly updated United States Wind Turbine Database (USWTDB). Starting from Energy Information Administration (EIA) data, locations of large-scale solar photovoltaic (LSPV) facilities were visually verified using high-resolution aerial imagery; a polygon was drawn around the extent of facility panel arrays, and facility attributes were appended. Quality assurance and control were achieved via team peer review and comparing the USPVDB to other datasets of U.S. solar photovoltaic. Some facility information did not exist within our source data or not yet built, not built at all, or located elsewhere. Thus, uncertainty may exist for certain facilities and are rated in a confidence level. None of the data are field verified.
