Residential Solar Photovoltaic (PV) System Potential

This dataset demonstrates an optimal size of PV system to be installed on a rooftop area. It is an analysis of residential rooftops (excluding apartment complexes) to estimate a potential capacity of a PV installation. The analysis uses LiDAR data taken in 2022 to estimate solar irradiance and roof shape to estimate the number of 1m x 2m solar panels. This data is then used with PVWatts API created by NREL to estimate the annual AC generated per panel. Each address has one or more entries each representing a continuous area where panels could be installed.
