Quick Answer
Vermont solar incentives in 2026 include full retail net metering for systems up to 500 kW, a 6% sales tax exemption, a property tax exemption for systems under 50 kW, a Clean Energy Development Fund rebate of $0.10/W capped at $3,500, and Green Mountain Power battery rebates up to $10,500. The federal residential ITC expired after 2025.
Vermont homeowners paid an average residential electricity rate of 22.14 cents per kWh in 2024, roughly 34% above the national average of 16.5 cents, according to the U.S. Energy Information Administration (2025). That gap matters. Every kilowatt-hour a rooftop system produces avoids one of the highest retail rates in the country.
The federal incentive picture changed in 2026. The 30% Residential Clean Energy Credit under Internal Revenue Code Section 25D expired for homeowner-owned systems placed in service after December 31, 2025. The math now depends almost entirely on state and utility programs.
Vermont still offers one of the stronger small-state incentive stacks in the country: full retail net metering, a sales tax exemption, a property tax exemption, a state rebate program, and one of the most aggressive utility battery incentives in the U.S. through Green Mountain Power. This guide explains each program, how they stack, and what the numbers look like for homeowners and installers in 2026.

Vermont Solar Incentives 2026 at a Glance
Vermont’s incentive stack is unusual for a state of its size. The table below lists the programs active in 2026 and their typical values.
| Incentive | Type | 2026 Status | Typical Value / Notes |
|---|---|---|---|
| Federal residential ITC (Section 25D) | Tax credit | Expired | $0 for cash or loan residential purchases placed in service after 2025 |
| Federal Section 48E ITC | Commercial tax credit | Active, deadlines apply | 30% for eligible commercial, lease, or PPA systems |
| Vermont net metering | Utility bill credit | Active | ~$0.1839/kWh blended rate; Category I systems 15 kW or less get a $0.01/kWh adder |
| Vermont sales tax exemption | Tax exemption | Active | 6% exemption on solar equipment for systems up to 500 kW |
| Vermont property tax exemption | Tax exemption | Active | Full exemption for systems under 50 kW under 32 V.S.A. § 3802 |
| CEDF residential solar rebate | Rebate | Verify current funding | Reported at $0.10/W, capped at $3,500 per project |
| Vermont state business ITC | Tax credit | Active | 24% of federal commercial ITC claimed, effectively ~7.2% of system cost |
| GMP BYOD battery rebate | Utility rebate | Active | $850–$950/kW, up to $10,500 per system |
| GMP ESS battery lease | Utility lease | Active | $55/month or $5,500 upfront for a 10-year lease |
| GMP ConnectedSolutions | Demand response | Active | ~$850/year for enrolled battery owners |
| ACRE community solar | Bill credit | Active, enrollment window | $29.55/month guaranteed credit for income-qualified households |
The main story is that Vermont solar economics are still driven by high retail rates and strong net metering. The federal credit loss hurts, but it does not erase the business case. The installers who win in Vermont are the ones who size systems tightly to usage, model net metering correctly, and know when a battery makes sense.
Key Takeaway
Vermont solar works in 2026 because of above-average electricity rates and full retail net metering, not because of a large federal tax credit. The state exemptions, CEDF rebate, and GMP battery programs fill part of the gap left by the expired Section 25D credit.
Vermont Net Metering: How Credits Work in 2026
Vermont’s net metering program is governed by the Vermont Public Utility Commission’s Rule 5.100 (2024). The program requires all Vermont electric utilities to offer net metering to customers who install eligible renewable energy systems up to 500 kW in capacity.
When a solar system produces more electricity than the home uses, the surplus flows to the grid. The utility credits the customer at the applicable blended residential rate. When the home uses more than the system produces, the customer draws power from the grid and the stored credits reduce the bill.
The base blended residential rate used for credit calculations is approximately $0.1839/kWh, according to EnergySage (2026). This is close to the retail rate, which is why Vermont is considered a strong net metering state.
Category I Residential Adder
Vermont assigns net-metered systems to categories based on size and site. Category I covers systems of 15 kW or less. These systems receive a $0.01/kWh credit adjuster on top of the blended rate for the first 10 years after interconnection. The adjuster is locked in at the time of interconnection.
Green Mountain Power customers who transfer their Renewable Energy Certificates (RECs) to GMP can receive an additional $0.03/kWh credit, bringing the total adder to $0.04/kWh for Category I systems. RECs represent the environmental attributes of the clean energy produced. Transferring them to the utility means the homeowner no longer owns those environmental claims, but the extra credit improves project economics.
Credit Rollover and Annual Settlement
Net metering credits roll forward month to month. Credits earned in high-production months, typically May through September, offset lower-production months in winter. Any unused credits expire after 12 months. The utility keeps the expired credits without payment.
This 12-month rollover is generous, but it still rewards right-sizing. A system that produces far more than the household consumes will eventually forfeit credits. The best designs in Vermont match annual solar production to annual usage rather than maximizing system size.
Group Net Metering Changes Under Act 179
Vermont historically allowed group or virtual net metering, where multiple customers shared the output of a single solar array located off-site. Act 179, enacted in 2024, changed the rules. For applications filed on or after January 1, 2025, group net metering is limited to systems on the same parcel or an adjacent parcel. The exception is affordable housing projects that filed before December 31, 2025.
This means community solar for renters and households without good roofs now flows mainly through dedicated programs like ACRE, not through traditional group net metering. For installers, the change removes one financing structure and makes on-site or adjacent-parcel design more important.
Vermont Solar Tax Exemptions
Vermont offers two straightforward tax benefits that reduce both upfront cost and long-term ownership expense.
Sales Tax Exemption
Vermont exempts solar photovoltaic equipment from the state’s 6% sales and use tax for systems up to 500 kW in capacity. The exemption covers panels, inverters, batteries, mounting hardware, wiring, and associated components. According to DSIRE (2026), the exemption applies to systems that generate electricity using eligible renewable energy resources.
For a typical 10 kW residential system costing around $27,500, the 6% sales tax exemption saves roughly $1,650. The exemption usually applies automatically at the point of sale, but homeowners should confirm that the installer has structured the invoice correctly.
Property Tax Exemption
Under 32 V.S.A. § 3802 (2025), solar energy systems under 50 kW are exempt from Vermont property tax assessment. This means the added market value from solar panels does not increase the property tax bill.
The exemption applies to systems that are net-metered or off-grid and serve only the property on which they are located. For systems of 50 kW or larger, the Uniform Capacity Tax applies instead. These larger systems pay $4 per kW of nameplate capacity annually rather than standard property tax on the equipment.
CEDF Rebate and Vermont Business Solar Tax Credit
Clean Energy Development Fund Residential Rebate
The Vermont Clean Energy Development Fund (CEDF) is administered through the Renewable Energy Resource Center (RERC). Several installer and marketplace sources report a residential solar rebate of $0.10 per watt, capped at $3,500 per project. On a 10 kW system, that equals a $1,000 upfront rebate.
Because CEDF funding cycles change and the RERC currently emphasizes wood heating and solar water heating incentives, homeowners should verify rebate availability with RERC or their installer before relying on it in a proposal. If the rebate is open, it is typically claimed after installation with supporting documentation.
Vermont State Investment Tax Credit for Businesses
Vermont businesses, including farms and commercial property owners, can claim a state income tax credit equal to 24% of the federal commercial ITC claimed under Section 48/48E. With the federal commercial ITC at 30%, the effective Vermont credit is approximately 7.2% of total system cost.
For example, a $100,000 commercial solar installation that qualifies for the 30% federal credit would also generate a roughly $7,200 Vermont state credit. This credit is for business taxpayers, not residential homeowners. Any business considering it should work with a tax professional to confirm eligibility and documentation.
Green Mountain Power Battery Programs
Green Mountain Power serves roughly 75% of Vermont’s residential electric customers. The utility has made battery storage a central part of its grid strategy and offers three main programs in 2026.
BYOD Battery Rebate
The Bring Your Own Device program gives GMP customers an upfront rebate for installing a qualifying battery and enrolling in the utility’s virtual power plant. The rebate is $850 per kW of enrolled capacity for batteries that discharge over three hours, or $950 per kW for four-hour batteries. The maximum rebate is $10,500 per system, and the minimum battery size is 5 kW.
An additional $100/kW bonus is available for customers who add a battery to an existing solar system in grid areas where storage provides the most value. The program requires a 10-year participation commitment. Program details and current terms are available on Green Mountain Power’s BYOD page.
Energy Storage Solutions Lease
GMP also offers a lease program for customers who want backup power without a large upfront purchase. Customers can lease two Tesla Powerwall or Enphase batteries for $55 per month or a one-time $5,500 payment over a 10-year term. GMP installs and maintains the system and retains the right to dispatch it during peak events.
ConnectedSolutions Demand Response
Battery owners enrolled in ConnectedSolutions can earn roughly $850 per year in exchange for allowing GMP to discharge stored energy during summer peak events. The events are short and do not typically leave the home without backup power.
For GMP customers, a battery can make strong sense in 2026. The BYOD rebate alone often covers a large share of the battery cost, and backup power is valuable during Vermont’s increasingly severe winter storms.
Low-Income and Community Solar Access
Not every Vermont household owns a roof that works for solar. The Affordable Community Renewable Energy (ACRE) program is designed for income-qualified households, including renters. Participants receive a guaranteed $29.55 monthly bill credit, roughly $355 per year, for subscribing to a community solar project. There is no enrollment fee and no equipment to install.
The 2026 enrollment window opened April 7, 2026, and closes August 31, 2026, according to Palmetto (2026). Eligibility is based on income guidelines set by the Vermont Public Service Department. Households that qualify should enroll during the open window, because the program does not accept applications year-round.
For commercial and low-income project developers, the loss of the federal Solar for All grant in 2025 changed project finance. Vermont’s Public Service Department and Attorney General’s Office were evaluating options to restore the funding as of mid-2025, reported by Environmental Health News (2025). Developers should treat low-income project finance as uncertain until a replacement funding source is confirmed.
Vermont Solar Cost, ROI, and Payback in 2026
Without the federal residential tax credit, the installed cost is the starting point. National residential solar pricing in 2026 averages around $2.75 per watt, with a typical range of $2.50 to $3.30 per watt, according to EnergySage and NREL data cited by Sunhub (2026).
A 10 kW system in Vermont therefore costs roughly $27,500 before incentives. After the 6% sales tax exemption and a $1,000 CEDF rebate, the effective out-of-pocket cost drops to about $24,850. The property tax exemption adds long-term value but does not reduce upfront cost.
Vermont’s average residential electricity rate is roughly $0.22/kWh. A 10 kW system in Vermont produces about 12,000 to 13,000 kWh per year, depending on shading, roof orientation, and snow cover. If the system offsets 11,000 kWh of grid purchases, the annual savings are roughly $2,420. That produces a simple payback of about 10.3 years and net savings of roughly $35,000 to $40,000 over a 25-year system life.
Adding a battery changes the math. A 10 kW battery might cost $10,000 to $14,000 before the GMP BYOD rebate. A $9,500 rebate on a qualifying battery reduces the net battery cost to $500 to $4,500. Even at the high end, backup power and increased self-consumption can justify the cost for GMP customers.
| System configuration | Estimated upfront cost | Net cost after Vermont incentives | Simple payback | 25-year net savings |
|---|---|---|---|---|
| 10 kW solar only | $27,500 | ~$24,850 | ~10 years | ~$35,000–$40,000 |
| 10 kW solar + 10 kW battery | $40,000 | ~$30,000–$34,000 | ~12–14 years | ~$40,000–$50,000 |
| 10 kW solar + battery with max BYOD rebate | $40,000 | ~$29,500 | ~11–13 years | ~$42,000–$52,000 |
These are estimates. Actual payback depends on roof conditions, utility rate trajectory, self-consumption rate, and whether the homeowner transfers RECs to GMP. Installers should model each project with site-specific production and usage data. Our best solar design software US guide compares the tools that make this workflow repeatable.
Common Mistakes and Financing Options
The most common mistake Vermont homeowners make in 2026 is assuming the federal tax credit still applies. Any installer promising a 30% federal credit on a cash purchase in 2026 is either misinformed or misleading. The credit is gone for homeowner-owned systems. Only third-party ownership structures, such as leases or power purchase agreements, can still capture Section 48E through a commercial owner.
The second mistake is oversizing. Because unused net metering credits expire after 12 months, a system that produces far more than the home consumes gives away value. Right-sizing to annual usage maximizes the value of every kilowatt-hour.
The third mistake is ignoring utility territory. GMP customers have access to battery rebates and demand response programs that Vermont Electric Cooperative or municipal utility customers may not. VEC customers should also note the 4 cent/kWh siting charge that applies to systems of 150 kW or smaller for applications dated August 1, 2024, or later.
Financing options for residential solar buyers in 2026 include cash purchase, solar loan, lease, and PPA. Cash and loans rely on bill savings and state incentives for payback. Leases and PPAs can pass through the commercial federal tax credit as a lower monthly payment, but the homeowner does not own the system or the RECs. Commercial solar and agricultural projects can also explore USDA REAP grants and the Vermont Economic Development Authority’s Commercial Energy Loan Program.

Commercial, lease, and PPA systems may still qualify under Section 48E, generally with construction beginning by July 4, 2026, or placed in service by December 31, 2027.
What is the Vermont property tax exemption for solar?
Under 32 V.S.A. § 3802, solar energy systems under 50 kW are exempt from Vermont property tax assessment. The added value from the system does not increase the homeowner’s property tax bill. Systems over 50 kW pay a Uniform Capacity Tax of $4/kW per year instead.
Does Vermont have a sales tax exemption for solar?
Yes. Vermont exempts solar photovoltaic equipment from the 6% state sales tax for systems up to 500 kW. The exemption typically applies automatically at the point of sale and covers panels, inverters, batteries, and associated components.
What is the GMP BYOD battery rebate?
Green Mountain Power’s Bring Your Own Device program pays GMP customers an upfront rebate of $850/kW for a 3-hour discharge battery or $950/kW for a 4-hour discharge battery, up to $10,500 per system. A $100/kW bonus is available for retrofitting existing solar in targeted grid areas.
What is the Vermont Clean Energy Development Fund solar rebate?
Market sources report a CEDF residential solar rebate of $0.10 per watt, capped at $3,500 per project and administered through the Renewable Energy Resource Center. Because CEDF funding cycles change, homeowners should confirm current availability with RERC or their installer before signing a contract.
What is the ACRE program in Vermont?
The Affordable Community Renewable Energy program gives income-qualified Vermont households a guaranteed $29.55 monthly bill credit, roughly $355 per year, for participating in community solar at no cost. The 2026 enrollment window runs from April 7 through August 31, 2026.
What is the typical solar payback period in Vermont in 2026?
A well-sited residential solar system in Vermont typically pays back in 9 to 13 years in 2026, assuming an installed cost near $2.75/W, a 10 kW system size, and an electricity rate of roughly $0.22/kWh. Adding a battery extends payback unless the GMP BYOD rebate covers most of the battery cost.
Do I need a battery with solar in Vermont?
A battery is not required for solar savings, but it helps during Vermont’s winter storms and ice-related outages. Green Mountain Power offers strong battery incentives that can make storage economical for GMP customers. For backup-only goals, a battery is usually worth it; for pure bill savings, the math depends on the rebate and self-consumption rate.
