Untapped Solar Potential

This feature layer contains both the solar potential aggregated to tract-level, and the percent of households in that tract using solar. This information allows us to identify tracts that have untapped solar potential. Original data for solar potential came from Global Solar Atlas, accessed via ArcGIS Living Atlas' PV Electricity Output and Horizontal and Tilted Irradiations layers. Original data for household solar usage came from Census' American Community Survey, accessed via ArcGIS Living Atlas' Housing Tenure by Heating Fuel layer. Using these inputs, we ran Zonal Statistics as a Table in ArcGIS Pro to aggregate the solar potential to each census tract.
