West Virginia solar calculator
Size a West Virginia home solar system from your electric bill — kW, panel count, roof area, true cost with no federal credit for 2026 installs, and payback.
Quick answer: At $0.158/kWh and 4.1 peak sun hours, a $200/month bill needs about 13.53 kW — 33 × 410 W panels covering ~66 m². Gross cost is ~$39,237 with no federal credit for systems installed after 2025, offsetting $2,400 a year for a ~16.3 year payback.
Your details
Ballpark, not gospel. Ballpark, not gospel. Sized at 78% real-world output with the West Virginia sun-hour average — confirm shading, roof angle and your utility's PSC-set export credit with a local installer before buying. 1:1 net metering is closed to new customers — exports earn a fixed 9.343¢/kWh (Mon Power/Potomac Edison) or 12.41¢/kWh (Appalachian Power/Wheeling Power). The calculator values all generation at your retail rate; exports earn far less, so real savings track self-consumption and batteries.
The 30% credit ended — what changed
The residential clean energy credit (26 U.S.C. § 25D) gave homeowners a 30% credit on solar installed from 2022 through 2025. The July 2025 tax law ended it: no credit is available for property placed in service after December 31, 2025. That is why every figure on this page is ~30% higher than pre-2026 guides show. If your system went live by the end of 2025, tick the box above to see the credit applied; leased systems may still benefit because the leasing company claims the commercial credit.

Solar in West Virginia: the details
Solar cost in West Virginia
Solar installation costs in West Virginia run mid-pack. The EnergySage marketplace averaged about $2.90 per watt installed in 2026, with market quotes typically landing $2.46–$3.33/W — inside the $2.50–$3.50/W national band. A typical ~13.5 kW West Virginia system grosses around $39,200 before any incentives, with no federal credit for 2026 homeowner installs.
What moves the number: roof complexity, panel tier, and installer competition. Get at least three quotes — spreads of $0.50/W between installers are common.
Export rules: getting paid for surplus power
West Virginia's 1:1 net metering is closed to new customers. New systems earn a fixed credit per exported kWh set by the Public Service Commission: 9.343¢/kWh at Mon Power/Potomac Edison and 12.41¢/kWh at Appalachian Power/Wheeling Power — against a ~15.8¢ retail rate — with credits rolling forward indefinitely (no annual true-up penalty).
Grandfathering cutoffs differ by utility: Mon Power's was December 31, 2024, Appalachian Power's March 1, 2026. One consumer-protection note: HOA bans on solar recorded after June 8, 2012 are unenforceable in West Virginia. Practical takeaway: exports earn roughly 60–80% of retail, so high self-consumption is what closes the payback gap.
West Virginia solar incentives
No major statewide solar incentive was found in 2026 sources. West Virginia offers no solar rebate, tax credit, or property tax exemption — and there is no sales tax break for solar equipment, so the 6% state sales tax applies: make sure your quotes include it.
With 1:1 net metering closed and no incentive stack, the economics rest entirely on self-consumption.
Is solar worth it in West Virginia?
Verdict: marginal. The calculator puts a $200/month bill at a ~16.3-year payback with no federal credit — and with exports earning a fixed 9.343¢/12.41¢ instead of the ~15.8¢ retail rate, self-consumption is what closes the gap. There's no incentive stack and the 6% sales tax applies, so this is a buy-only-if-you-use-it-during-the-day market. Size carefully.

Systems installed by the end of 2025 can still claim 30%, and leased systems may still benefit because the leasing company claims the commercial credit instead.
