Solar calculator for West Virginia
Panels, system size, cost and payback for West Virginia, from your own power bill.
The average West Virginia home uses 1,027 kWh a month and pays 15.1 cents per kWh, which puts West Virginia at mid-range electricity prices, so payback depends mostly on how much sun your roof gets. West Virginia has both a heating and a cooling season, so the bill swings both ways and a full year of bills gives a better answer than one month. A south-facing fixed array there makes about 1,219 kWh per installed kW a year, and the worst winter month still gets 2.6 peak sun hours a day. Drop in your own bill below and the numbers on this page are replaced by yours.
A worked example for West Virginia
Take the average home: 1,027 kWh a month, which is 12,324 kWh a year, at 15.1 cents per kWh (EIA, 2024 residential averages, as of 2026-11). Sized to cover all of that use, the tool returns 10.1 kWdc and 25 panels, needing about 525 square feet of roof. The installed estimate is $25,174 (national median, EnergySage H2 2025), yearly savings are about $1,861, and simple payback is 13.5 years, with no incentive applied.
Sun and yield in West Virginia
We use 1,219 kWh per installed kW per year for West Virginia, from NREL PVWatts v8 for the state's largest city at a 20 degree south-facing tilt (via TheGreenWatt, as of 2026-11). The darkest month averages 2.6 peak sun hours a day, which matters if you plan to go off-grid or size a battery. A different roof angle or heavy shade changes this, so treat it as a starting point.
Incentives
The 30% federal tax credit ended for homeowner purchases after December 31, 2025, so none is applied here. See the tax credit guide. Look up West Virginia and your own utility for net metering terms and any local programs before relying on a payback number.
