CharlestonSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Charleston homeowners stack the 30% federal tax credit and 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 11.1 years.
Solar Incentives Available in Charleston
Solar incentives in Charleston come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. West Virginia does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, 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.
