South Carolina Solar Panel Permits and Installation Rules

Solar PV installations require permits under SC Code 6-9-50 (state building code adoption) and follow the National Electrical Code Article 690 as adopted statewide. Local building departments issue permits, but cannot impose interconnection rules conflicting with the SC Energy Freedom Act of 2019 (SC Code 58-40 and 58-41). The Public Service Commission regulates utility net metering tariffs uniformly. Installations on residential rooftops generally require structural review, electrical permit, and inspection. Licensed contractors performing solar work must hold appropriate SC contractor licenses through the Department of Labor, Licensing and Regulation. Roof-mounted residential systems under 20 kW typically follow streamlined permit processes. The Energy Freedom Act preempts local moratoria on solar by establishing statewide interconnection standards.

Unpermitted installations can trigger stop-work orders, mandatory inspections of concealed work, removal orders, denial of utility interconnection, and fines varying by local jurisdiction.
