Why this number

Solar panels in Virginia cost about $2.52 per watt — $20,160 for a typical 8 kW system — and pay back in roughly 11.7 years at the state’s 17.6¢/kWh average rate, with the 2026 federal credit at $0. Full-retail net metering is assumed; confirm with your utility.

Everything below uses Virginia’s real average residential electricity rate (17.6¢/kWh, EIA) and a production band of about 1,330 kWh per kW per year. Both are stated openly because they are the two inputs that decide the answer. These are estimates for sanity-checking a quote, not a quote.

Run it with your own numbers

Why Virginia’s payback lands where it does

Virginia’s rate jumped about eleven percent this year, from 15.78 cents per kilowatt-hour in July 2025 to 17.6 cents this July, one of the sharper increases in the model and enough to push the state to rank 19. Decent yield of 1,330 kilowatt-hours per installed kilowatt combines with that fast-rising rate to bring the payback down to about 11.7 years. Virginia Electric & Power, the Dominion Energy utility and by far the largest with over 2.38 million residential customers, actually bills well below the state average at 14.1 cents, meaning most Virginia solar owners, concentrated in Dominion’s territory, face a payback longer than the 11.7-year statewide figure suggests, while Appalachian Power customers, at 17.0 cents, sit much closer to it. Full retail net metering credits exports at whichever rate applies, so the gap between Dominion’s price and the state average is the single most important number here.

The state average hides real spreads between utilities. The largest residential utilities EIA-861 lists for Virginia, with each one’s own average bundled residential price (2024 — revenue ÷ sales, the audited annual figure, not this month’s tariff):

Your utility decides Virginia’s real number — the ZIP lookup finds it in three clicks; the 2024 annual utility averages above sit apart from the June-2026 monthly 17.6¢ state figure.

An 8 kW system in Virginia, priced out

The $2.52/W used above comes from EnergySage marketplace quotes (August 2026). Those are quotes in a competitive online market, not signed contract prices.

Read that table with one caveat: $2.52/W is Virginia’s market average, and it is the input most likely to differ for you. A quote $0.50 per watt above or below the $2.52 used here moves the payback by roughly a year and a half in either direction.

How much sun Virginia actually gets

A kilowatt of panels in Virginia produces about 1,330 kWh a year on an unshaded, south-facing roof at a 20-degree pitch. Sites that swap Virginia’s 1,330 kWh for a single national average are how Arizona and Washington end up with identical paybacks despite a 1.6x real difference in output.

That figure is a five-point cluster around Virginia’s largest metro area, which keeps it representative of where most people actually live rather than of the state’s best site.

Two adjustments matter before you apply this to your own roof:

• Shading and orientation. The 1,330 kWh figure assumes an unobstructed south-facing array. A real Virginia roof — its own azimuth and pitch, a tree or a chimney — typically produces 10-25% less; this page models 90% of the ideal, so the 9,576 kWh/year above is already derated from 10,640. A genuinely unshaded south roof can adjust upward in the calculator.
• Year-to-year weather moves output by roughly ±5% either way.

How Virginia compares with the other 49

Virginia ranks 19th of 50 on electricity price and 22nd on annual output value per kW installed — close enough that its rate is a fair proxy for its solar case, which is not true everywhere. Its immediate neighbors on price are Delaware (18.5¢) just above and Minnesota (17.4¢) just below.

Delaware is Virginia’s closest comparable-rate analogue — 18.5¢/kWh, roughly 1,270 kWh per kW, and a payback within about a year of this one (11.7 vs 11.7 years). If you find Virginia quotes hard to sanity-check, Delaware numbers are broadly transferable.

The export question worth asking your Virginia utility

Virginia credits exported power at the retail rate — full net metering — under Dominion Net Metering 2.0, in force since 2026-04-30, so a kilowatt-hour you send to the grid is worth the same as one you buy. That is the best case for solar economics, and it is why the payback above is what it is.

It is also the assumption most likely to change. Twenty-two states have already moved to net billing. If Virginia did the same on typical terms, this system would take about 18.0 years to pay back instead of 11.7 — 6.3 years’ difference from a policy change, with no change to the hardware. The households best placed for that day are the ones already storing their surplus, which is why what a home battery actually costs is worth knowing even while full retail holds.

12-month netting retained, but annual excess is now settled at avoided cost plus roughly 1c rather than at retail.

One limit worth knowing: this reflects investor-owned, state-regulated utilities; Virginia’s municipal utilities and co-ops are exempt in most cases and set their own terms.

What is actually left in Virginia

The 30% federal credit ended for systems completed after December 31, 2025, so it is $0 here as everywhere. What remains is state, utility and local — and it varies far more than the federal rule ever did.

Virginia offers no state-level solar tax credit or rebate. Utility-level rebates, and the tax exemptions below, are where any remaining help comes from — those are set locally, so DSIRE and your own utility are the places to look.

Tax exemptions

Property-tax treatment is a local decision — full or partial, decided locally. Ask your assessor before assuming either way.

If that list looks thin, it is — the solar incentives hub shows which states still put real money on the table, and where Virginia sits among them.

Is solar worth it in Virginia at 17.6¢/kWh?

Virginia is close to the national middle on both inputs, which makes it the state where the quote matters most. At 17.6¢ and 1,330 kWh per kW there is no margin from geography to absorb an expensive installer.

If you want a fast gut check before running the numbers above, the should-I-go-solar screener asks the four questions that matter most in a mid-rate state like Virginia.

Two numbers put that in context. At Virginia’s rate, the electricity an 8 kW system would produce is worth about $1,681 a year, so the system costs roughly 12.0 years of that output to buy outright — a simple division, before costs. The headline 11.7-year figure above is the full model: it additionally counts 2.5%/yr rate inflation, $150/yr of running costs and one inverter replacement, which is why the two differ slightly. And doing nothing is not free: 25 years of that same electricity, with rates rising at 2.5% a year, comes to about $57,419.

For a 15-year payback in Virginia — given its sunshine rather than a national average — the electricity rate would need to be about 14.5¢/kWh. Virginia is at 17.6¢, which is comfortably above that line.

Frequently asked questions

How we calculated this

Worked for Virginia: 8 kW × 1,000 × $2.52/W = $20,160 gross (federal credit $0, so net before state incentives); 9,576 kWh a year × the blended kWh value at 17.6¢ retail ≈ $1,681 year-1 saving; payback ≈ $20,160 ÷ $1,681 = 11.7 years with 2.5%/yr rate growth, 0.5%/yr degradation and one inverter replacement in the 25-year model.
