Today, many jurisdictions have the option of saving time with automated validation for solar PV systems. Automated permitting streamlines the permitting process and ensures consistency during the validation of solar PV system designs. In 2021, the National Renewable Energy Laboratory (NREL) worked with IREC and other partners to develop SolarAPP+, short for Solar Automated Permit Processing. This is an online automated design validation tool that can evaluate many new residential rooftop solar PV systems.
