Do I need a permit for solar panel installation in Charleston?
Yes. In South Carolina, solar panel installation generally requires a permit, and Charleston is no exception.
Utility interconnection and net metering approval is a separate process from the building permit and is handled by your electric provider. In coastal Charleston, roof-mounted arrays must account for wind uplift and roof structural capacity, so a structural review is common. Charleston processes solar panel permits through its Customer Self Service (CSS) portal, and because a solar install changes the electrical system and adds roof loading it requires a permit and inspections regardless of system size. On a property in the Old and Historic District, or where an array would be visible from the public right of way, the Board of Architectural Review may need to approve a Certificate of Appropriateness for panel placement before the building permit is issued. Coordinate the utility interconnection separately, and confirm roof framing and mounting details with the Permit Center before applying, since roof mounted arrays are reviewed for both electrical and structural compliance.
