South Carolina enjoys nearly 5 peak sun hours daily and has emerged as one of the Southeast's strongest solar markets. The Palmetto State's combination of a generous state tax credit and mandatory net metering creates compelling economics for residential solar.

South Carolina offers a 25% state income tax credit up to $3,500 for residential solar systems, one of the better state credits in the Southeast. Duke Energy Carolinas and Dominion Energy South Carolina offer full retail net metering. The state also provides a sales tax exemption for solar energy equipment and has seen strong growth in community solar programs.

Charleston, Columbia, and Greenville are the leading residential solar markets. With the state and federal tax credits stacking together, solid sunshine, and full net metering, South Carolina homeowners typically achieve payback periods of 7-10 years.
