Digitized geospatial dataset of ground-mounted solar energy panel-rows in the United States

Overview This project provides manually digitized solar panel-rows to fill gaps in and enhance coverage of solar array sub-array design metadata in the US. In doing so, this dataset supports the existing project, The Ground-Mounted Solar Energy in the United States (GM-SEUS) dataset, recently published in Scientific Data. GM-SEUS is a harmonized, open access, and regularly updated geospatial and temporal repository of solar energy arrays and panel-rows). GM-SEUS contains spatiotemporal information and value-added attributes for commercial- (<1 MWDC) and utility-scale (≥1 MWDC) solar photovoltaic (PV) and concentrating solar power (CSP) installations in the United States (US). This data will be included in the GM-SEUS version update (version 1.1). NOTE: We initially planned to contribute this dataset of manually annotated panel-row geometries to OpenStreetMap (OSM), a critical resource supporting GM-SEUS. Feedback from the OSM community surfaced two conflicts with conventional OSM approaches that we are not planning to resolve within this dataset, as it already meets our research needs. Accordingly, we are not proceeding with the import. We continue to rely on OSM as a critical resource for GM-SEUS and support future, standards-aligned contributions. See our GM-SEUS Solar Panel-Rows OSM Wiki page and the Community Forum Post for more information. The entire hand delineated dataset contains 24,182 hand-delineated solar panel-rows (5.29 km²) composing 1,485 arrays previously without panel-row data, spanning the Contiguous United States (CONUS) and digitized by Charlie Bonten. Of these, 23,870 panel-rows did not conflate with existing OpenStreetMap contributions, and composed 1,450 arrays. As of August 29th, 2025, this upload represents a 2.1% increase in panel-row count and a 23.1% increase in the number of arrays with panel-row data in OpenStreetMap. These panel-rows are the intended contribution to OpenStreetMap. We omit the solar farm/array boundaries, since these were generated by an automated process.
