Do I need a permit for solar panel installation in Mount Pleasant?
Yes. In South Carolina, solar panel installation generally requires a permit, and Mount Pleasant 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. A solar install changes the electrical system and adds roof loading, so Mount Pleasant requires a permit and inspections through the Online Permitting Portal (OPAL) regardless of system size, under the adopted 2021 South Carolina codes. Because Mount Pleasant is a coastal town, a roof mounted array is reviewed for structural attachment against high-wind uplift, so mounting and framing details are checked before the permit is issued. On a home in the Old Village Historic District, panel placement that is visible can require a Certificate of Appropriateness from the Historic District Preservation Commission, and the utility interconnection is coordinated separately.
