Quick Answer: Solar Permits & Incentives in South Carolina
Permitting solar energy systems in South Carolina involves two parallel processes. First, obtain a local building permit from the Authority Having Jurisdiction (AHJ), which is your city or county building department. Second, apply for utility interconnection, governed by South Carolina Public Service Commission (PSC) guidelines adopted in December 2006.
South Carolina homeowners benefit from a robust incentive structure. The state offers a 25% personal income tax credit for purchasing and installing qualifying solar systems (S.B. 1141 of 2009, administered by the South Carolina Department of Revenue). This credit stacks with the 30% federal Residential Clean Energy Credit under IRS §25D. Santee Cooper customers have additional options: a rooftop solar rebate program and low-interest renewable energy resource loans. The South Carolina Energy Office administers the ConserFund Loan Program for public entities and non-profits.
Local permit requirements vary. Greenville, Columbia, and Charleston each have their own fee schedules, submittal checklists, and inspection sequences. Confirm specifics with each city or county building department before finalizing a contract.
