Do I need a permit for solar panel installation in Cary?
Yes. In North Carolina, solar panel installation generally requires a permit, and Cary is no exception.
A rooftop or ground-mounted PV system involves both structural and electrical work, so it is never covered by the NCGS 160D-1110 minor-work exemption and requires a permit. Interconnection with the utility is a separate approval from your building permit; both must be completed before the system is energized. A residential solar photovoltaic system requires a permit from the Town of Cary, and the Town notes that reinstalling equipment when a roof is replaced also needs a permit, so plan for permitting even on a reroof of an existing solar home. Cary determines the required inspections (electrical, building, and sometimes plumbing or mechanical) at plan review and lists them on the permit, so review the Town's Electric Solar (PV) Photovoltaic Guide before applying. All electrical equipment must be listed and labeled by an approved testing agency, and the installation is inspected to the applicable North Carolina codes and the manufacturer's instructions. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. Solar involves electrical work and roof loading, so permits are required regardless of cost.
