What solar panel installation costs in Charleston
Construction pricing in South Carolina runs 10% below the national average, so solar panel installation here typically lands between $15,070 and $18,346 for a typical 7 kW system. At South Carolina's 14.3¢/kWh electricity rate, a system that size offsets a meaningful share of a typical bill. Note: the 30% federal solar tax credit expired December 31, 2025, so these are gross prices — any quote still showing a federal credit is out of date.
Figures are modeled from 2026 national baselines adjusted by a South Carolina cost factor of 0.90. They are estimates for comparison, not quotes — your property, access and material choices move the real number.
