Many municipalities and other authorities having jurisdiction (AHJs) are facing dramatic increases in rooftop solar permit applications. With this trend expected to continue and spread, streamlining building and electrical permitting processes will become increasingly important to more AHJs. To facilitate such streamlining, IREC and Vote Solar have identified nine Best Practices in Residential Solar Permitting, which should result in benefits to both AHJs and solar installers. Underlying these best practices is the goal of increased consistency of solar permitting processes across jurisdictions. When technical and procedural requirements are relatively consistent—regionally, statewide, or even nationally—it can offer significant efficiency benefits for both AHJs and the solar industry.
