CharlestonSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Charleston homeowners installing in 2026 cannot claim the federal residential credit. What remains is Appalachian Power net metering. At 4 peak sun hours a day, a home with a $130/month bill (about 929 kWh) needs roughly a 9.7 kW system — 25 panels — and pays back in about 15.1 years.
Solar Incentives Available in Charleston
The federal residential credit does not apply to a Charleston system installed in 2026. West Virginia does not add a state income tax credit in this dataset. Appalachian Power sets the local rules for crediting the solar power you export.
Appalachian Power serves Charleston with net metering; on West Virginia's coal-heavy grid, rooftop solar is an increasingly competitive hedge.
