Do I need a permit for solar panel installation in Westerville?
Yes. In Ohio, solar panel installation generally requires a permit, and Westerville is no exception.
A rooftop or ground-mounted PV system involves both structural and electrical work, so under the Residential Code of Ohio it requires a permit and is not covered by any minor-repair exemption. Utility interconnection is a separate approval from your building or electrical permit; both must be complete before the system is energized. A residential solar installation in Westerville needs both a residential building permit and an electrical permit, and the city notes a separate Interconnection Agreement Fee that is collected by the Westerville Electric Division, apart from the building and electrical permits. Because Westerville owns and operates its own municipal electric utility, coordinate the interconnection and any meter or service work with the Westerville Electric Division as part of your solar project. Homes in the Uptown historic district can require a Certificate of Appropriateness from the Uptown Review Board, and those applications are only heard at monthly meetings.
