Model Policy Library
This model policy gives states a template to encourage local governments to adopt automated rooftop solar permitting software. The software, SolarAPP+, helps lower the cost of rooftop solar permitting and inspection to governments, homeowners, and solar businesses by standardizing, streamlining and automating the permitting process.
