Software to speed up permitting proceedings for rooftop PV

The National Renewable Energy Laboratory and UL have joined forces to develop Solar Automated Permit Processing Plus software. NREL has committed to adding new features to SolarAPP+ until March 2023.

The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has signed a memorandum of understanding with Underwriters Laboratories, a U.S. nonprofit standards development organization, to develop and commercialize Solar Automated Permit Processing Plus (SolarAPP+) software. The software automates the permitting process for residential solar systems.
