Scenario: a 2,000 sq ft home. Assumes 3%/yr rate increases, 0.5%/yr panel degradation and no federal tax credit (the 30% §25D credit ended for systems installed after Dec 31, 2025). How we calculate
Data approachEIA rates · NREL sun hours · 2026 federal policy · methodology
Using floor area as a rough proxy (about 0.45 kWh per sq ft per month), a 2,000 square foot home in West Virginia would use about 899 kWh per month — about $139/month at West Virginia’s average residential rate of 15.47¢/kWh (EIA, Jan–Jul 2026 year-to-date). Real usage varies widely with climate, heating fuel and household size, so size your system from your actual kWh on your utility bills. With 4.2 peak sun hours per day, offsetting that usage takes about a 8.6 kW solar system — roughly 22 panels at 400W — costing about $25,700 installed. With no federal tax credit for 2026 installs and West Virginia’s full retail net metering, simple payback is about 17.7 years, with an estimated $23,800 net over 25 years.
How Many Solar Panels for a 2,000 sq ft House in West Virginia?
West Virginia electricity rates and sun hours change panel count versus the US average:
System size (kW) = Annual kWh ÷ (Peak sun hours × 365 × 0.82)
For 2,000 sq ft in West Virginia:
Estimated monthly usage: ~899 kWh
Peak sun hours: 4.2 h/day
System size:8.6 kW (~22 × 400W panels)

💰 System Cost
What Does Solar Cost for a 2,000 sq ft Home in West Virginia in 2026?
At about $3.00/W installed (a blended 2026 US price; marketplace quotes often run lower), a 8.6 kW system in West Virginia costs about $25,700.
The 30% federal Residential Clean Energy Credit (IRC §25D) ended for systems installed after December 31, 2025, so a solar system you buy and install in 2026 gets no federal tax credit. Leases and PPAs are different: the installer that owns the system can still claim the commercial §48E credit for systems placed in service by the end of 2027 and may pass part of that value on through a lower monthly price.
📈 Payback Period
How Long Is Solar Payback on a 2,000 sq ft Home in West Virginia?
West Virginia requires net metering for residential systems up to 25 kW; recent rate cases have modified export credits for some utilities. We assume solar offsets about 87% of this home’s ~$139/month bill — roughly $1,452/year — for a simple payback of about 17.7 years.
Over 25 years, with 3% annual rate increases and 0.5%/year panel degradation, cumulative savings minus the installed cost come to about $23,800. Full retail net metering means each kWh you produce is worth close to your retail rate.

Net metering
Full retail net metering — solar assumed to offset 87% of the bill. West Virginia requires net metering for residential systems up to 25 kW; recent rate cases have modified export credits for some utilities.
Square footage
Used only as a rough usage proxy: 2,000 sq ft × 0.4495 kWh/sq ft/month. EIA: average US residential customer used about 899 kWh/month (2022). Site assumption: that usage corresponds to a ~2,000 sq ft home (0.45 kWh per sq ft per month). Square footage is only a rough proxy — size from your actual kWh.
