Vermont Solar Incentives 2026: GMP Net Metering, Tax Exemptions & Rebates

Vermont rounds out New England's solar incentive landscape with retail-rate net metering protected by state law, a property tax exemption under 32 V.S.A. § 3845, and Efficiency Vermont cash rebates for qualifying installations. High electricity rates — among the highest in the Northeast at $0.21–$0.25/kWh — mean Vermont homeowners often achieve 8–12 year payback periods despite the northern latitude. If you're evaluating solar in Vermont, this guide covers every incentive available in 2026 and how to stack them for maximum savings.

Vermont Solar Resource: Better Than You Think

Vermont sits between 42.7° and 45.0° north latitude, which leads many homeowners to underestimate solar potential. In reality, Vermont receives 4.2–4.9 peak sun hours per day on an annual average basis — comparable to Germany, which leads the world in solar adoption per capita.

The key dynamic in Vermont: high electricity rates offset lower sun hours. At $0.22/kWh average, every kWh your solar panels produce avoids a more expensive utility bill than the same kWh produced in Arizona ($0.13/kWh). A 10 kW system that produces 12,000 kWh/year saves $2,640/year in Vermont vs. $1,560/year in Phoenix — even though Phoenix has significantly more sun.

Vermont peak sun hours by region:

• Burlington / Chittenden County: 4.3–4.7 peak sun hours/day
• Barre / Central Vermont: 4.2–4.6 peak sun hours/day
• Montpelier metro: 4.2–4.5 peak sun hours/day
• Southern Vermont (Brattleboro, Bennington): 4.4–4.9 peak sun hours/day

South-facing roofs with 30–40° pitch perform best. Even modest shading from trees can reduce output significantly; Vermont's late-afternoon sun angles make west-facing roofs more viable than in sunnier states.

Federal Solar Tax Credit: 30% (Extended Through 2032)

Vermont homeowners qualify for the federal Investment Tax Credit (ITC) at 30% of gross system cost, with no dollar cap. The ITC is claimed on IRS Form 5695 when you file your federal taxes for the year the system is placed in service.

Vermont ITC examples (2026):

System Size	Installed Cost	30% ITC	Net After ITC
7 kW	$24,500	$7,350	$17,150
9 kW	$31,500	$9,450	$22,050
11 kW	$38,500	$11,550	$26,950
14 kW	$49,000	$14,700	$34,300

Critical ITC rules:

• You must own the system (not lease) to claim the credit
• The credit is non-refundable — it reduces your tax liability but won't generate a refund if the credit exceeds what you owe
• Unused credit carries forward to future tax years indefinitely
• Battery storage paired with solar qualifies for the same 30% ITC
• Standalone battery storage (not paired with solar) also qualifies for 30% ITC if charged at least 40% from renewables

If your Vermont tax bill is typically $3,000–$8,000/year, you may need to spread the ITC claim across multiple years. Consult a tax professional about your carry-forward strategy.

Vermont Net Metering: Retail Rate, Protected by Law

Vermont's net metering program is one of the most buyer-friendly in New England. Under Title 30 V.S.A. § 219a and the Vermont Public Utility Commission (PUC) rules, all Vermont electric utilities must offer net metering to residential customers with systems up to 150 kW AC (a very high cap that covers virtually any home installation).

Key Vermont net metering terms (2026):

• Compensation rate: Full retail rate — for Green Mountain Power (GMP) customers, that's $0.21–$0.25/kWh depending on rate class
• Billing period: Monthly netting — surplus production in any given month offsets consumption at retail rates
• Annual true-up: Surplus kWh credits roll forward month to month indefinitely. At the end of the April billing cycle (Vermont's official annual netting period), excess credits are typically cashed out at the utility's avoided-cost rate (~$0.05–$0.08/kWh). Design your system to produce roughly what you consume annually — don't oversize expecting to profit from the annual settlement.
• Interconnection: PUC net metering rules cover all utilities; GMP processes most residential applications within 30–60 days
• Metering: Standard bidirectional net meter is installed by the utility at no cost for most residential installations

Vermont utility coverage:

• Green Mountain Power (GMP): Serves approximately 75% of Vermont customers. Statewide reach including Burlington, Essex, South Burlington, Colchester, Williston, and most of Chittenden County. GMP is the most progressive Vermont utility on solar — it also runs battery storage and EV charging programs.
• Central Vermont Public Service (CVPS): Now merged into Green Mountain Power since 2012 — all GMP customers as of 2026
• Vermont Electric Cooperative (VEC): Serves about 32,000 customers in northeastern Vermont (Orleans, Essex, Caledonia counties, Northeast Kingdom). VEC is a rural cooperative that offers net metering per PUC rules, though interconnection timelines can be longer.
• Burlington Electric Department (BED): Municipal utility serving Burlington. Offers net metering under BED tariff, generally favorable. BED has its own rate schedule (rates typically $0.22–$0.28/kWh).
• Washington Electric Cooperative (WEC): Small cooperative in central Vermont; net metering available per PUC rules.

System sizing implication: Size your array to cover approximately 95–100% of your annual kWh consumption. Vermont's dark winter months mean annual production is skewed toward summer — you'll have a large summer surplus and a winter deficit. Monthly netting means summer credits offset winter bills at full retail rates — but only up to what you consume in those winter months. The April annual true-up settles any remaining surplus at avoided cost, which makes over-sizing economically inefficient.

Vermont Property Tax Exemption: 32 V.S.A. § 3845

Vermont law exempts residential solar installations from property tax assessment under 32 V.S.A. § 3845. This means the value your solar system adds to your home is not added to the taxable assessed value — you pay no additional property taxes as a result of going solar.

How much this saves: Vermont's effective property tax rate averages 1.82% statewide, though it varies significantly by town (Burlington is lower at ~1.3%; rural towns can be higher at 2.0–2.5%). Property values added by solar typically range from $15,000–$30,000 per Zillow research.

Property Tax Rate	Added Value	Annual Tax Avoided	20-Year Savings
1.3% (Burlington)	$20,000	$260/year	$5,200
1.8% (state avg)	$20,000	$360/year	$7,200
2.2% (rural town)	$20,000	$440/year	$8,800

How to qualify: The exemption is automatic under state law — no application is required. Your local assessor should not add the solar system value to your grand list assessment when your next revaluation occurs.

Caveat: Vermont's property tax system is complex (education tax is statewide, municipality rate varies). Some assessors in smaller towns may not be aware of the exemption. If you see your assessment increase after installing solar, contact your town assessor and cite 32 V.S.A. § 3845.

Vermont Sales Tax: No Exemption (Notable Gap)

Unlike New Hampshire, Rhode Island, Connecticut, Massachusetts, New York, and most other northeastern states, Vermont does not offer a sales tax exemption for residential solar installations. Vermont's statewide sales tax rate is 6%, which adds $1,500–$3,000 to the cost of a typical residential system.

This is the most significant incentive gap compared to Vermont's neighbors. When budgeting for your installation, include Vermont's 6% sales tax on solar equipment in your cost estimates. Some local meals and rooms taxes apply in certain municipalities, but these don't typically apply to solar equipment sales.

Efficiency Vermont Cash Rebates: Up to $1,000+

Efficiency Vermont (EVT) — the nation's first statewide energy efficiency utility — offers cash rebates for residential solar and solar-plus-storage installations. These rebates have varied over the years; as of 2026, check the current program at efficiencyvermont.com for the most current incentive tiers.

2026 Efficiency Vermont solar rebate structure:

• Standard solar PV: $400–$750 for systems 3–10 kW; paid upon installation completion and verification
• Solar + battery storage: Up to $1,000–$1,500 for paired solar and battery storage systems (incentive is higher because GMP and EVT actively want distributed battery storage for grid stability)
• Income-qualified enhanced rate: Low-to-moderate income (LMI) households may qualify for enhanced rebates of $1,500–$2,500 through EVT's income-qualified programs. Contact EVT directly for eligibility.

How to access: Your solar installer must be a registered EVT trade ally or submit the application on your behalf. Rebate funds are available on a first-come, first-served basis and programs occasionally pause when funding is exhausted mid-year. Apply early in the installation process to hold your place in queue.

GMP Battery Programs: Green Mountain Power offers Vermont's most innovative battery storage programs:

• Powerwall Lease Program: GMP leases Tesla Powerwall units to customers at $15/month; GMP retains the right to dispatch the battery during grid events in exchange for the reduced-cost lease. This is not ownership, but it dramatically lowers the entry cost for battery backup.
• GMP Connect: Virtual power plant enrollment where battery owners earn bill credits for grid support events

USDA REAP Grants: 25–50% for Farms and Rural Businesses

If you operate a farm or rural small business in Vermont, the USDA Rural Energy for America Program (REAP) offers grants covering 25–50% of eligible solar costs, with the 50% level reserved for smaller systems in underserved areas. Vermont has a strong agricultural economy and REAP is a major opportunity for dairy farms, maple operations, orchards, and rural commercial businesses.

REAP 2026 details:

• Eligible: Farms, agricultural producers, rural small businesses (in areas with <50,000 population)
• Grant amount: 25–50% of eligible project costs (IRS Inflation Reduction Act expanded funding significantly)
• Applies to: Solar PV, battery storage, wind, geothermal for production and commercial use
• Application: USDA Vermont State Office processes applications; multiple funding rounds per year
• Stacking: REAP grant + 30% federal ITC can cover 55–80% of total project costs for Vermont farms

A Vermont dairy farm installing a 50 kW solar system at $125,000 could receive:

• REAP grant (30%): $37,500
• Federal ITC (30% of remaining $87,500): $26,250
• Total incentives: $63,750 — net cost: $61,250 (51% of original cost)

Contact the USDA Vermont Service Center in Montpelier for REAP application timelines and current funding availability.

Vermont Renewable Energy Standard and SRECs

Vermont has a Renewable Energy Standard (RES) requiring utilities to source an increasing percentage of electricity from renewable sources. However, unlike New Jersey, Massachusetts, or Illinois, Vermont does not have an active residential Solar Renewable Energy Certificate (SREC) market that pays homeowners for their certificates.

Under Vermont's net metering structure, your utility effectively retires the renewable attributes of your production on your behalf in exchange for the retail-rate credit. Homeowners do not separately sell SRECs — the net metering compensation already incorporates this value.

This is structurally different from NJ, MA, or IL where homeowners separately earn SREC income on top of net metering. Vermont's retail net metering rate is generous enough that the absence of a separate SREC market isn't a significant disadvantage for most homeowners.

Low-Income Programs: Vermont Solar for All and EmPower Vermont

Vermont Solar for All: Vermont received IRA funding to expand solar access for low-income households. Green Mountain Power runs income-qualified solar programs, and Efficiency Vermont's income-qualified rebate (mentioned above) offers enhanced incentives for households earning up to 80% of area median income (AMI).

EmPower Vermont: Administered by Efficiency Vermont, this program provides home energy assessments and upgrades including weatherization, heat pumps, and — in some cases — solar readiness improvements for income-qualified households. Solar itself may not be directly funded under EmPower, but weatherization reduces the size (and cost) of the solar array needed to offset your remaining energy use.

Contact: Call 888-921-5990 (Efficiency Vermont) or visit efficiencyvermont.com/income to check income-qualified eligibility.

Vermont Stacking Example: Burlington 9 kW System

Let's calculate the full incentive stack for a Burlington, Vermont homeowner going solar in 2026:

System details:

• Location: Burlington, VT (4.5 peak sun hours/day)
• System size: 9 kW DC
• Estimated production: 10,800 kWh/year
• Household consumption: 11,500 kWh/year (typical Vermont home with electric heat supplement)
• GMP electricity rate: $0.22/kWh

Costs:

• Gross installed cost: $31,500 ($3.50/W — Vermont market rate)
• Vermont sales tax (6%): $1,890 (included in gross cost)

Incentives:

• Federal 30% ITC: −$9,450
• Efficiency Vermont rebate: −$700 (standard, system registered with EVT)
• Property tax exemption: −$260/year (1.3% Burlington rate × $20,000 added value = $4,680 over 18 years NPV)

Net cost: $21,350 ($22,700 after-sales-tax)

Annual savings:

• Solar offsets 10,800 kWh × $0.22/kWh = $2,376/year
• GMP net metering bill credit: ~$700/year (winter shortfall at $0.22/kWh)
• Net annual electricity bill with solar: ~$700 vs. $2,530 without solar = savings of $1,830/year

Simple payback: ~$21,350 ÷ $1,830/year = 11.7 years

25-year total savings (including property tax NPV): approximately $35,000–$42,000 depending on GMP rate increases (averaging 3–4%/year historically).

Vermont Stacking Example: Montpelier 7 kW System

For a smaller Montpelier home with lower consumption:

Component	Cost / Value
Gross installed cost	$24,500
Federal ITC (30%)	−$7,350
EVT rebate	−$600
Net cost	$16,550
Annual production	~8,400 kWh/year
Annual savings	~$1,430/year
Simple payback	~11.6 years

Vermont vs. New England Neighbors: Incentive Comparison

State	State Credit	Property Tax Exemption	Sales Tax Exemption	Best Program	Median Payback
Vermont	None	✅ Full (§ 3845)	❌ (6% applies)	EVT rebate, GMP battery	10–14 years
Massachusetts	None	✅ 20-year exemption	✅ Full 6.25%	SMART PBI ($0.15–$0.22/kWh)	4–8 years
Connecticut	None	✅ Full	✅ Full 6.35%	RSIP ($0.20–$0.26/kWh)	3–6 years
Rhode Island	None	✅ Full	✅ Full 7%	REF rebate ($0.20–$0.35/W)	5–9 years
New Hampshire	None	✅ (municipality opt-in)	✅ No sales tax	No sales tax (automatic)	7–11 years
New York	25% credit (max $5K)	✅ RPTL §487	✅ Full	NY-Sun + 25% state credit	4–9 years

Vermont's incentive stack is the thinnest in New England — no state income tax credit and no sales tax exemption are the two key gaps. However, high electricity rates ($0.21–$0.25/kWh) partially compensate. The GMP battery lease program is Vermont's most innovative feature and a meaningful option if you want backup power at low upfront cost.

Is Solar Worth It in Vermont? Decision Checklist

Vermont solar is worth strong consideration if you:

• Own your home with at least 10–15 years remaining before a potential sale
• Have an unshaded south-facing roof (or east/west with minimal shading)
• Pay GMP rates of $0.21+/kWh or Burlington Electric $0.22+/kWh
• Have federal tax liability of at least $7,000–$10,000 (to absorb the ITC over 1–3 years)
• Heat with electricity (heat pump) or plan to — makes the system payback faster
• Are considering an EV — solar + EV is particularly compelling in Vermont given high rates

Vermont solar is less compelling if:

• Your roof is significantly shaded by trees (Vermont's sun angles make shading more impactful than in southern states)
• You heat primarily with very low-cost fuel oil or propane (though oil price volatility makes the comparison less stable)
• You have minimal federal tax liability (ITC carry-forward can address this over several years)
• Your remaining time in the home is under 7–8 years

How to Go Solar in Vermont: Step-by-Step

1. Get 3 quotes from Vermont-licensed solar installers. NABCEP certification is the gold standard. Use the best solar companies guide to identify credentials to look for.
2. Size your system correctly — pull your GMP bill for the last 12 months and determine annual kWh consumption. Use the Solar System Designer for a preliminary sizing estimate.
3. Apply for EVT rebate — your installer should register the project with Efficiency Vermont before installation begins. Don't miss this step; it's easy for installers to forget.
4. Understand the net metering contract — GMP will send you a net metering agreement to sign before installation. Review it with your installer.
5. File for the federal ITC — use IRS Form 5695 when filing your taxes for the installation year. Your installer should provide documentation of the system cost.
6. Verify property tax assessment — after installation, confirm with your local assessor that the solar value is not being added to your taxable assessment.

Vermont Solar FAQs

Does Vermont have a state solar tax credit? No. Vermont does not offer a state income tax credit for residential solar. This is the most significant gap compared to most New England neighbors. The federal 30% ITC is the primary tax benefit for Vermont homeowners.

Can I sell excess solar power back to the grid in Vermont? Yes — Vermont net metering credits your excess production at the full retail rate each month. Annual surplus (any remaining credits at the April true-up) is settled at the utility's avoided-cost rate, typically $0.05–$0.08/kWh.

What happens to net metering credits if I sell my home? Net metering credits stay with the meter/account. If you sell your home, the buyer takes over the net metering agreement and inherits any banked credits. Solar adds resale value to Vermont homes — Zillow research suggests $4 per watt of capacity on average.

How long does solar permitting take in Vermont? Most Vermont towns process building permits in 4–8 weeks. Interconnection approval from GMP or VEC is typically 4–8 weeks afterward. Total time from contract to Permission to Operate (PTO) is typically 3–6 months. See the solar installation timeline guide for a full breakdown.

Is the Green Mountain Power Powerwall lease worth it? At $15/month ($180/year), the GMP Powerwall lease program is compelling if you primarily want backup power during outages rather than grid-independence or TOU optimization. You don't own the battery, so it doesn't add resale value, and GMP controls dispatch. If you want the 30% ITC on the battery, you must purchase (not lease) — owned batteries qualify for the ITC, leased ones do not.

Next Steps

Vermont solar requires more careful payback analysis than states with richer incentive stacks — but high electricity rates and protected retail-rate net metering make the investment viable for most homeowners with good roof exposure. Before signing with an installer, compare at least three proposals using the how to read a solar quote guide and model your numbers with the payback period calculator.

For neighboring state comparisons, see the New Hampshire solar guide, Massachusetts solar guide, Connecticut solar guide, and Rhode Island solar guide.
