South Carolina Solar Installation: Complete 2025 Guide

South Carolina homeowners are discovering excellent solar opportunities with 4.8-5.2 peak sun hours daily and average electricity rates of $0.12-$0.13 per kWh. Combined with federal incentives and state programs, South Carolina solar offers compelling economics and energy independence.

South Carolina Solar Incentives and Rebates

Federal Solar Tax Credit (30%)

⚠️ URGENT: The federal solar tax credit expires December 31, 2025. The One Big Beautiful Bill (OBBB) signed July 4, 2025 shortened this incentive by 9 years from its original December 31, 2025 expiration. Systems must be installed and operational by year-end to qualify.

South Carolina residents can claim the federal Investment Tax Credit (ITC), providing a 30% tax credit on total solar installation costs through December 31, 2025.

State and Local Incentives

South Carolina offers additional solar benefits including net metering, property tax exemptions, and utility-specific rebate programs. Check with your local utility for current offerings.
