Incentives by town · South Carolina
Solar incentives across South Carolina
South Carolina's three headline incentives are identical everywhere: a 25% state income tax credit on Form TC-38 capped at $3,500 a year, property-tax exemption on qualifying systems of 20 kW or less, and sales-tax exemption on equipment.
What is not identical is your utility. Santee Cooper runs a genuine rebate but is waitlisted. Duke ran PowerPair, which closed in Progress territory and has been at or near capacity in Carolinas. Dominion offers no upfront rebate at all. Cooperatives set their own terms entirely.
So each page below leads with your utility rather than the state credit, because that is the part that actually differs and the part that decides whether a system is worth installing.
By utility
Grouped by who bills you
Your utility decides more about a solar system than any equipment choice, so these are grouped that way rather than alphabetically. Territory can vary by address, which we confirm at the assessment.
