Why this number

Solar panels in Vermont cost about $2.76 per watt — $22,080 for a typical 8 kW system — and pay back in roughly 15.4 years at the state’s 23.8¢/kWh average rate, with the 2026 federal credit at $0. Net billing pays exports below retail here.

Everything below uses Vermont’s real average residential electricity rate (23.8¢/kWh, EIA) and a production band of about 1,125 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.

Why Vermont’s payback lands where it does

Vermont’s average rate climbed about seven percent to 23.8 cents per kilowatt-hour this July from 22.14 cents a year earlier, the eleventh-highest rate nationally. That elevated rate is doing most of the work behind the state’s 15.4-year payback, since yield here is weak at just 1,125 kilowatt-hours per installed kilowatt — New England’s tree cover and northern latitude take a real toll. Green Mountain Power, the state’s largest utility with nearly 227,000 residential customers, prices below the statewide average at 22.1 cents, so its customers should expect a payback a bit longer than the 15.4-year state figure, while Vermont Electric Cooperative, at 23.3 cents, comes closer to it. Vermont compensates exports under net billing rather than full retail, so it’s mainly the high rate paid on self-consumed power, not the export credit, that lets a state with such a mediocre solar resource still manage a payback under sixteen years.

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

An 8 kW system in Vermont, priced out

The $2.76/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: $2.76/W is Vermont’s market average, and it is the input most likely to differ for you. A quote $0.50 per watt above or below the $2.76 used here moves the payback by roughly a year and a half in either direction.

How much sun Vermont actually gets

A kilowatt of panels in Vermont produces about 1,125 kWh a year on an unshaded, south-facing roof at a 20-degree pitch. Sites that swap Vermont’s 1,125 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 Vermont’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 1,125 kWh figure assumes an unobstructed south-facing array. A real Vermont 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 8,100 kWh/year above is already derated from 9,000. A genuinely unshaded south roof can adjust upward in the calculator.
• Year-to-year weather moves output by roughly ±5% either way. Snow is not modeled either, and costs a further 2-5% in a state like this one.

A solar resource this thin usually comes with a real winter, and in a state like Vermont the larger energy-bill lever is often heating rather than generation — see heat pump vs gas furnace running costs and our winter heating cost data before assuming panels are the first move. The heat pump vs. furnace cost calculator runs that comparison at Vermont’s own 23.8¢/kWh rate.

How Vermont compares with the other 49

Vermont ranks 11th of 50 on electricity price and 14th 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 Connecticut (24.2¢) just above and Michigan (23.1¢) just below.

Connecticut is Vermont’s closest comparable-rate analogue — 24.2¢/kWh, roughly 1,235 kWh per kW, and a payback about 2.2 years apart (17.6 vs 15.4 years). Use it as a directional marker rather than a proxy — the gap is real.

Net billing: the rule that decides solar in Vermont

Vermont does not credit exports at the retail rate — this is net billing , not net metering. The program is PUC Rule 5.100, in force since 2026-08-01, and it credits surplus power at a published rate of 14.40¢/kWh — against a retail rate of 23.8¢.

Blended 20.71c less a 5c siting adjuster.

Because a typical Vermont home uses only about 40% of its generation as it is produced, most of what the panels make is sold at 14.4¢. That is why the payback above is 15.4 years rather than the 11.1 years the same hardware would return under full-retail net metering. Raising self-consumption — a battery (worth its own arithmetic: is a home battery worth it? ), an EV charged in daylight, daytime occupancy — is the lever that closes the gap. Whether a Vermont buyer should own a battery or take a lease/TPO deal is priced in the battery buy vs. TPO calculator .

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

What is actually left in Vermont

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.

Vermont 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

Sales tax is exempt (6.0% state rate), which keeps roughly $1,325 off the upfront cost of the system modeled here.

Property tax is fully exempt on the added value, so the system does not raise your assessment. Roughly 1.56%/yr.

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

Is solar worth it in Vermont at 23.8¢/kWh?

Vermont is a marginal case dressed up by an above-average rate. Production near 1,125 kWh per kW is genuinely low, so a quote above $2.76 a watt can push this from reasonable to not worth doing.

At a horizon that long, owning the roof is not the only route to cheaper power. Community solar versus rooftop walks through the subscription alternative — no roof, no loan, and no 15.4-year wait — which is worth reading before committing capital in a market like Vermont’s.

Two numbers put that in context. At Vermont’s rate, the electricity an 8 kW system would produce is worth about $1,469 a year, so the system costs roughly 15.0 years of that output to buy outright — a simple division, before costs. The headline 15.4-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 $65,720.

For a 15-year payback in Vermont — given its sunshine rather than a national average — the electricity rate would need to be about 18.6¢/kWh. Vermont is at 23.8¢, which is comfortably above that line.

Frequently asked questions

How we calculated this

Worked for Vermont: 8 kW × 1,000 × $2.76/W = $22,080 gross (federal credit $0, so net before state incentives); 8,100 kWh a year × the blended kWh value at 23.8¢ retail and 14.4¢ export ≈ $1,469 year-1 saving; payback ≈ $22,080 ÷ $1,469 = 15.4 years with 2.5%/yr rate growth, 0.5%/yr degradation and one inverter replacement in the 25-year model.
