Data approachEIA rates · NREL sun hours · 2026 federal policy · methodology
Solar can still pay off in Vermont in 2026, but the math is slower than it was a year ago. The 30% federal homeowner tax credit ended on December 31, 2025, so a typical 8 kW system costs about $22,000 before state exemptions and pays for itself in roughly 12 to 14 years in our model. What keeps Vermont solar viable is electricity cost: the state’s average residential price has run well above the national average, so every kilowatt-hour your panels produce replaces expensive grid power.
This guide uses current figures from the Vermont Public Utility Commission, the U.S. Energy Information Administration (EIA), IRS-based federal guidance, and EnergySage pricing. Where we model savings, we state the assumptions so you can rerun the numbers with your own quote. The policy picture is also in motion, so we call out what could still change.
⚖️ Policy & Net Metering
How Vermont Net Metering Works in 2026 (and What Happened to Group Net Metering)
Net metering lets a solar owner send surplus power to the grid and receive bill credits. In Vermont, it is available for systems up to 500 kW under Public Utility Commission (PUC) Rule 5.100, and net-metered systems must go through the PUC’s approval process, either a registration or a Certificate of Public Good depending on size. Credits bank and can be applied to later bills for up to 12 months.
Compensation is not a flat retail credit. Per the PUC, credit value is built from the statewide blended residential rate, then raised or lowered by adjustors tied to system size, siting, and other factors. Before the 2026 update, the blended rate was 18.4 cents per kWh. The PUC’s 2026 biennial update order, issued May 29, 2026, rejected proposals to freeze the blended rate and cut compensation for existing systems, but it did reduce the siting adjustor by 1 cent per kWh for Category I and II systems. In its September 9, 2026 rulemaking order, the PUC said a residential-scale system applying in 2026 would be paid about $0.1571 per kWh for generation that exceeds monthly usage.
That September order also opened a new rulemaking (Case No. 26-1786-RULE) to redesign net-metering compensation. The PUC said any new framework should include a transition for existing systems, but the final design is not set. If you are buying a system, confirm current credit values with your utility and ask your installer what happens to your economics if compensation changes.
Group net metering is where the old version of this guide is now out of date. Act 179 of 2024 ended virtual group net metering for applications after December 31, 2024, with a limited exception for affordable housing developers, and the Department of Public Service has recommended a successor program that had not been created at the time of writing. If you rent, or your roof is shaded, there is currently no new community solar subscription to join in Vermont. Existing subscribers continue to receive credits.
💰 System Cost
Vermont Solar Costs and Payback Period Without the Federal Credit
EnergySage reported an average Vermont installed price of about $2.76 per watt in August 2026, with an average quoted system around 11 kW costing roughly $30,000 before incentives. At that price, an 8 kW system costs about $22,080. Vermont’s 6% sales tax exemption applies to qualifying systems, so you should not pay sales tax on top of the equipment price.
Here is the model behind our example. It assumes 1,100 kWh of production per kW per year (8,800 kWh for 8 kW), 0.5% annual panel degradation, flat electricity rates, and three credit values: 18.4 cents (the pre-update blended rate), 20 cents (a middle case), and 22 cents (roughly Green Mountain Power’s average residential price). Production varies by roof and shading, so check your address in PVWatts.
Data visualization
Cumulative net savings of an 8 kW Vermont system over 25 years. Breakeven falls between years 11.7 and 14.1 on a $22,080 install at $2.76/W (EnergySage, Aug 2026), 8,800 kWh/yr, 0.5%/yr degradation, flat rates, no federal credit. Illustrative model, not a quote.
Chart takeaway: In this model, the system breaks even in about 14.1 years at an 18.4-cent credit, 12.9 years at 20 cents, and 11.7 years at 22 cents. Over 25 years, net savings come to roughly $16,100, $19,400, and $23,500. Because the model holds rates flat, rising utility prices would improve these results and falling credit values would worsen them. To apply this credit correctly, start with a firm figure from our guide to How Much Do Solar Panels Cost in 2026?.
If you finance, interest adds to the timeline. For example, a $22,080 loan at an illustrative 7% APR over 12 years has a payment of about $227 per month, while average bill savings in this model are roughly $147 per month. That means cash flow can be negative for much of the loan term even though lifetime savings are positive. Compare cash price, loan APR, and any dealer fee before choosing.
Green Mountain Power Rates and What Your Panels Offset
Vermont electricity is expensive relative to most of the country. EIA data put the statewide average residential price above 22 cents per kWh in 2026, compared with a national average near 18 cents. Green Mountain Power (GMP), which serves the majority of Vermont households, averaged about 22 cents per kWh for residential customers in EIA’s 2024 utility data, while Burlington Electric averaged about 19 cents.
Your savings depend on what each solar kilowatt-hour actually offsets. Power you use in the same month displaces retail electricity, while excess generation is credited under the PUC’s blended-rate formula, which is lower. That is why system sizing matters. The average Vermont household uses roughly 480 to 530 kWh per month, or about 6,000 to 6,300 kWh per year, so an 8 kW system producing about 8,800 kWh makes sense mainly for homes with heat pumps, EV charging, or electric water heating. A smaller household may be better served by a 5 to 6 kW system.
GMP also offers home battery programs that can pay customers to share stored energy during grid peaks. Terms, caps, and eligibility change, so verify details with GMP before counting on any battery incentive in your numbers. Vermont’s Renewable Energy Standard, as amended by Act 179, requires utilities to reach 100% renewable supply by 2035, which supports demand for local solar, but it does not guarantee future net-metering credit values.
🏛️ Incentives
Federal and State Incentives for Vermont Solar in 2026
Federal: The 30% Residential Clean Energy Credit under Section 25D ended for property placed in service after December 31, 2025, with no phase-down. Homeowners who bought and finished a system in 2026 cannot claim it. Credit carried forward from a system completed in 2025 or earlier can still be used against future tax. Third-party-owned systems, meaning leases and power purchase agreements, can still benefit from the business credit under Section 48E if the project meets its timing rules (construction begun by July 4, 2026, or placed in service by December 31, 2027). Any savings are passed to you only through the contract terms, and you do not own the system, so read the escalator and buyout clauses carefully. Ask a tax professional about your situation.
Vermont sales tax: Solar systems up to 500 kW are exempt from the state’s 6% sales tax. On a $22,000 system, that is about $1,300 you do not pay.
Vermont property tax: Vermont exempts solar systems under 50 kW from the uniform capacity tax, and municipalities may offer a local property tax exemption for solar. Adoption varies by town, so ask your listers before assuming your added home value is exempt.
What Vermont does not offer: There is no state income tax credit for homeowner solar and no general state rebate. Separate federal and state programs for heat pumps and weatherization exist, but they do not reduce the cost of solar panels. Because incentives change quickly, check DSIRE and the Vermont Department of Public Service before signing.
✅ Worth It?
Is Solar Worth It in Vermont? Three Scenarios
All three scenarios use the same assumptions as above: $2.76 per watt, 1,100 kWh per kW, a 20-cent credit value, 0.5% annual degradation, and flat rates. They are illustrations, not quotes.
Data visualization
25-year net savings by Vermont scenario. The south-facing 10 kW case nets about $24,200 versus about $10,800 for a shaded 6 kW roof, at $2.76/W and a 20-cent credit value. Source: EnergySage pricing, our model.
Chart summary: Orientation and shading drive the gap. The south-facing systems break even in about 12.9 years, while the shaded east-west roof takes about 14.8 years and earns less than half as much over 25 years. All three assume flat rates and no federal credit, so higher future utility prices would raise every bar.
South-facing home with electric heating or an EV (10 kW). Cost is about $27,600, production about 11,000 kWh per year, and annual value about $2,200. Payback is roughly 12.9 years and 25-year net savings are about $24,200. This is the strongest case because most output is used on site.
Partly shaded east-west roof (6 kW). We assume production is 12% below the south-facing case. Cost is about $16,560, production about 5,800 kWh, and annual value about $1,160. Payback is about 14.8 years and 25-year net savings are about $10,800. It still works financially over a 25-year warranty window, but the margin is thinner and a bad quote could erase it.
Renter, condo owner, or unsuitable roof. New virtual community solar is not currently available in Vermont, so the best options today are to ask the property owner about on-site solar, keep an existing community solar subscription if you have one, or focus on efficiency and heat pumps. A successor program could change this, so watch the Department of Public Service.
Bottom line: solar in Vermont is now a long-horizon investment rather than a quick win. It is most compelling for owners with sunny roofs, high electricity use, and a plan to stay in the home for at least 15 years. Get at least three quotes, compare price per watt, and ask each installer how they model net-metering credits under the PUC’s 2026 rules.
Sources and Last Verified
Last reviewed October 5, 2026. Figures in this guide come from the following sources, and rates and rules may change.
No, not for homeowners who buy with cash or a loan. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act. Credits earned on systems finished by that date can still be carried forward. Leases and power purchase agreements may still pass through the business credit (Section 48E) if the project meets its timing rules, so ask any provider which credit applies and how it affects your price.
Vermont net metering is available for systems up to 500 kW and is administered under Public Utility Commission Rule 5.100. Your meter nets production against usage, and bill credits bank for later months. Credit value is based on the statewide blended residential rate, adjusted up or down by PUC adjustors for system size and siting. The PUC issued a biennial update on May 29, 2026 and opened a rulemaking on September 9, 2026 that could change compensation for future systems, so confirm current rates with your utility before signing.
EnergySage reported an average Vermont installed price of about $2.76 per watt in August 2026, which puts an 8 kW system near $22,000 before incentives. At a credit value of 18 to 22 cents per kWh, our model gives a payback of roughly 12 to 14 years for a south-facing system with no federal credit. Shading, roof angle, financing costs, and how much of your output is used in the same month will move that number.
Not for new projects right now. Act 179 of 2024 ended virtual group net metering for applications after December 31, 2024, with a limited exception for affordable housing developers. Existing community solar subscriptions continue, and group systems adjacent to the property can still qualify. The Department of Public Service has recommended a successor program, but none was in place at the time of writing. Renters can ask landlords about on-site solar or look at utility programs.
Vermont does not offer a state income tax credit or a general homeowner solar rebate. It does exempt solar systems up to 500 kW from the 6% sales tax, which saves about $1,300 on a $22,000 system. Systems under 50 kW are generally exempt from the state's uniform capacity tax, and municipalities may offer their own property tax exemption, so check with your town listers. Utility battery programs, such as Green Mountain Power's, change often, so verify terms directly.
