While most states spent 2026 cutting what they pay for rooftop solar, Vermont went the other way. On May 29, 2026 the Public Utility Commission issued its order in the biennial update, case 26-0291-INV, and net-metering compensation went up rather than down. Combine that with the most expensive electricity in this group at 23.52¢ per kilowatt-hour and the smallest systems, and Vermont produces among the shortest paybacks in the country: under ten years.
The Rate Went Up, Which Almost Nowhere Else Did
Vermont does not use one-to-one net metering. Under statewide Commission Rule 5.100 your generation is credited at a blended residential rate, adjusted up or down by two modifiers: a renewable energy certificate adjustor and a siting adjustor that rewards putting panels somewhere uncontroversial. A rooftop array up to 15 kW is Category I, which carries the most favorable siting treatment available.
Under the previous NM 2.6 terms the statewide blended rate was 18.3¢ with a 4¢ Category I adjustor, which put Green Mountain Power customers at roughly 15.0¢ for self-consumed power and 14.3¢ for excess. The May 2026 order raised compensation from there. Reported figures put the new statewide blended rate near 20.7¢ with new systems gaining about 1.3¢, but the Commission’s own rate filings do not present a single consolidated figure in one place, so confirm your exact Category I figure with your utility before you model anything. What is verified is the direction and the date: compensation rose, on May 29, 2026, under Rule 5.128.
That order followed roughly 900 public comments, nearly all of them opposing the Department of Public Service’s push to restrain the program. It is a useful signal about where Vermont’s politics sit on this, though it is not a guarantee about the next biennial update.

Small Roofs, Expensive Power, Short Payback
Vermont households use less electricity than anywhere else in this group, 574 kWh a month, but pay the most for it. That combination is unusually good for solar: you need very little hardware to make a real dent in an expensive bill. At $2.89 per watt (as of March 1, 2026) the typical system is just 5.43 kW at about $15,687 gross, among the smallest and cheapest anywhere.
Small-roof sizes at the benchmark, gross before incentives:
| System size | Gross at Vermont’s $2.89/W benchmark |
|---|---|
| 4 kW | $11,560 |
| 5 kW | $14,450 |
| 5.43 kW, the typical Vermont system | $15,687 |
| 8 kW | $23,120 |
| 10 kW | $28,900 |
| What works against you | What works for you |
|---|---|
| Weakest sunlight in this group, 1,269 kWh per kW a year | Most expensive power in this group, 23.52¢/kWh |
| Compensation is a blended rate, not full retail | Fastest rate escalation in this group, 4.34% a year |
| Off-site group net metering closed to new projects on December 31, 2025 | Smallest system needed, so the lowest gross cost to recover |
Net it out and a system producing roughly 6,891 kWh a year displaces about $1,621 of electricity, a 9.7-year payback, modeled at the 23.52¢ statewide average. That is among the shortest modeled paybacks in the country, and it is driven by the price of power rather than by the amount of sun. The federal residential credit is $0 for owner-purchased systems whose installation is completed after December 31, 2025 under Public Law 119-21, and Vermont still clears ten years without it.
Treat that figure as a ceiling rather than a promise: it values every unit at the statewide average, while Vermont actually compensates net-metered output at a blended rate with adjustors, which this page describes below. A quote that conflates the two overstates your return, so ask your utility for your exact Category I compensation before relying on any payback number, including this one.
Locked at Enrollment, Which Cuts Both Ways
Vermont’s adjustors are fixed at enrollment, so the terms you sign up under travel with your system rather than floating. If you enroll while compensation is high, you keep that. If you enroll just before an increase, you keep the lower figure. Since the biennial update runs on a two-year cycle and the most recent one moved upward, the timing question here is genuinely live rather than rhetorical, and it is worth asking your installer which rate your application will land under.
Who Should Still Hesitate in Vermont
- Anyone told they will receive full retail credit. Vermont credits a blended rate with adjustors, not the 23.52¢ you pay. A quote that conflates the two overstates your return substantially.
- Anyone planning an off-site or group project. Off-site group net metering closed to new projects on December 31, 2025.
- Heavily shaded or north-facing roofs. With the weakest sunlight in this group, Vermont has the least margin for a compromised array.
- Vermont Electric Cooperative and Burlington Electric customers modeling on Green Mountain Power figures. Rates differ by utility, and Burlington’s are materially lower.
Vermont Solar Cost FAQs
About $2.89 per watt installed, 26th cheapest in the country as of March 1, 2026. Vermont households use less power than any other state in this group at 574 kWh a month, so the typical system is small at 5.43 kW, roughly $15,687 before incentives.
Yes, and upward. The Public Utility Commission issued its biennial update order in case 26-0291-INV on May 29, 2026, adjusting compensation under Rule 5.128, and net-metering compensation increased rather than decreased. Confirm your exact Category I figure with your utility, because rates differ between Green Mountain Power, Vermont Electric Cooperative and Burlington Electric.
Through a blended residential rate adjusted by a renewable energy certificate adjustor and a siting adjustor, under statewide Commission Rule 5.100, rather than at full retail. A rooftop system up to 15 kW is Category I and receives the most favorable siting treatment. Adjustors are locked at enrollment, so your terms travel with the system.
About 9.7 years, modeled at the statewide average and among the shortest in the country. That is driven by the price of power rather than the amount of sun: Vermont has the weakest sunlight in the group at 1,269 kWh per kW but the most expensive electricity at 23.52¢, and rates are rising 4.34% a year.
Not a new off-site group net metering project. That route closed to new projects on December 31, 2025. Existing arrangements continue, and rooftop Category I systems remain the standard path for a household that wants its own generation.
Expensive power and a small roof make this one work. Enter your ZIP code and we will confirm your rate and your numbers.

Methodology: cost figures use the EcoGen Solar Cost Index for Vermont, $2.89 per watt as of March 1, 2026, with payback modeled with no federal residential credit for owner-purchased systems, the year-one value modeled at the statewide average retail price as a ceiling, with actual compensation set by the blended rate and Category I adjustor described above, rate escalation at the state 5-year average of 4.34%, 0.5% annual panel degradation, and a 25-year horizon. The May 29, 2026 order date and the direction of the change are verified from the Commission’s own notice; the specific post-order cents-per-kWh figures circulating publicly could not be read from the Commission’s rate documents and are therefore described rather than quoted as settled.
