West Virginia's net metering rate now depends on your utility and when you signed up
A 2024 rate settlement changed net metering for two of the state's three utilities
Following a contentious rate case, Mon Power and Potomac Edison, both FirstEnergy companies, reached a settlement with the West Virginia Public Service Commission, solar advocacy groups, and Solar Holler, the state's largest solar installer, in February 2024. Under the settlement, customers who submitted their net metering application before January 1, 2025 are grandfathered at the full retail rate for 25 years. Customers applying on or after that date are instead credited 9.343 cents per kWh for excess generation at the end of their billing cycle, below the full retail rate those same customers pay for electricity they draw from the grid. This settlement resolved an earlier, more aggressive utility proposal that would have set the rate closer to 4.5 cents per kWh, so the final outcome represented a partial win for solar advocates rather than either side's original position. Appalachian Power customers have continued to receive the full retail rate as of this writing, and this rate has not been affected by the FirstEnergy settlement, though a separate, related case involving Appalachian Power's parent company has reportedly been under review by the commission, with some analysts watching it as a signal for how a similar case might play out. Confirm your specific utility's current terms before finalizing your project, since this is one of the more consequential numbers in your overall math.
West Virginia's sales tax treatment is genuinely disputed across sources
This is worth being direct about, since sources conflict without an obvious way to resolve the disagreement from available guides. Some sources describe a statewide sales tax exemption for solar equipment, citing savings in the range of $1,000 to $2,500 depending on system cost and local rate. Other sources state plainly that West Virginia does not provide a statewide solar sales tax exemption at all. Given this direct conflict, don't assume either way. Ask your installer for a written, itemized quote showing whether sales tax is charged on your specific invoice, and run the numbers both ways with the sales tax exemption savings calculator. Before you count on any incentive, check the DSIRE database of state incentives for your state's current programs.
The property tax exemption is broadly confirmed, though sources describe its duration differently
West Virginia exempts the added home value from a residential solar installation from property tax assessment, which most sources describe without specifying an end date, treating it as an ongoing protection for as long as the system remains in place. At least one detailed, recently verified source describes a specific 10-year term for this exemption instead. Given this discrepancy between an apparently open-ended benefit and a specifically time-limited one, confirm the actual duration with your county assessor's office rather than assuming either framing applies to your situation. Use the property tax exemption savings calculator to estimate the value under either scenario.
No statewide battery incentive exists yet, but a large federal grant could still matter
West Virginia does not currently offer a state-specific battery storage incentive, though batteries above 3 kWh remain eligible for whatever federal incentive still applies given your ownership structure. Separately, the EPA awarded West Virginia more than $106 million in April 2024 under a federal program aimed at boosting residential solar access statewide, with eligibility details and an application process expected to be announced. This funding has real potential to become a meaningful incentive once details are finalized, so it's worth checking current status with your installer or the state energy office rather than assuming it doesn't apply to you. Some utility-specific rebates in the $1,500 to $2,000 range have also been reported from Appalachian Power and FirstEnergy in certain service areas, worth asking about directly. Compare the overall picture against a neighboring state with the Kentucky incentive estimator or the Maryland incentive estimator.
