Solar panel cost across South Carolina

South Carolina solar runs around $2.59 per watt installed before incentives as of July 2026, but a single state average hides the thing that decides your payback: what your utility credits you for exported power.

Myrtle Beach has the lowest retail rate we work with at about 11.4¢ per kWh, which lengthens payback, and the only real upfront rebate, which shortens it. Dominion territory sits near 14.4¢ with no rebate. Duke credits exports at only a few cents. Those are not small differences over 25 years.

Each page below applies the local benchmark, works the 25% state credit through its $3,500 annual cap, and shows payback as a range against self-consumption rather than one flattering number.

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.
