Because solar permitting is handled by the local municipality, the permitting process will vary based on where you live. Most localities require installers to file for a solar permit, the stipulations of which differ by jurisdiction. Solar permits are in place to ensure that your system is installed safely and follows local code. From a customer perspective, you should not have to file any of the local permits yourself. Your installer should handle all permitting aspects themselves, including submitting the permit application and getting the solar system inspected.
