South Carolina Solar Market Analysis
South Carolina's solar economics are strengthened by moderate electricity costs of $0.14/kWh paired with an installed system cost of $2.65/W as of 2026. With average peak sun hours of 5.1 per day, residential systems generate consistent output across the state's climate. After accounting for the federal Investment Tax Credit, homeowners typically recover their solar investment within 8–10 years, with systems continuing to produce electricity for decades beyond payback.
State-level incentives further improve the financial picture. South Carolina's Energy Freedom Act guarantees net metering, allowing homeowners to bank excess solar generation and draw from it during low-production periods. Duke Energy Carolinas, the state's dominant utility provider, offers solar programs that complement residential installations. Additionally, the Residential Property Tax Exemption removes solar equipment from property tax assessments, preserving home equity gains from the system installation and reducing lifetime ownership costs.
