With $0.22/kWh average rates (GMP), net metering with a positive adjustor, property and sales tax exemptions, and Efficiency VT rebates, solar still pencils out. An 8 kW system at $3.20/W costs $25,600 gross, saves ~$2,112/year, and pays back in ~12 years cash. 25-year savings: $35,000-$45,000. No federal ITC (25D expired Dec 31, 2025). No state solar rebate (Vermont never had one). The sales tax exemption (saves $1,536) expires June 30, 2026.

No fluff — just the numbers. Here is exactly what an 8 kW system costs and earns in Vermont in 2026.
Assumptions: 8 kW south-facing roof system, GMP service territory, 70% self-consumption at retail rate + 30% export at Cat I net metering rate (~$0.14/kWh), 2.5% annual rate escalation, 0.4%/yr panel degradation, cash purchase. Individual results vary by roof orientation, shading, and utility.
Despite losing the federal ITC and lacking a state rebate, these factors keep Vermont solar financially viable.
Cat I residential systems locked for 10 years
Vermont residential systems under 15 kW qualify for Category I net metering. You receive the blended retail rate ($0.1839/kWh) PLUS a positive adjustor of ~$0.04/kWh, giving an effective credit rate of ~$0.14/kWh for exports. This adjustor is locked for 10 years from your interconnection date — protecting you from the VT PUC annual rate cuts during that period.
32 V.S.A. §3802 — automatic, no application
Vermont law exempts solar systems under 50 kW from property tax assessment. Solar adds roughly $20,000 to your home's value — and that added value is NOT taxed. At Vermont's average property tax rate (~$2.00/$100 assessed), that saves approximately $400/year. Over 25 years, that's $10,000 in avoided property taxes.
6% state sales tax on all equipment, labor, and batteries
Vermont exempts solar equipment, installation labor, and battery storage from the 6% state sales tax. On an 8 kW system at $25,600, this saves $1,536. The exemption is currently scheduled to expire June 30, 2026. After that date, every installation gets a $1,500+ price increase automatically. This is a genuine deadline — not marketing urgency.
$475/head ductless, $2,200/ducted, income-eligible bonuses
While VT has no state solar rebate, Efficiency Vermont offers substantial rebates for heat pumps installed alongside solar. Ductless mini-splits: $475/head, up to $1,900. Ducted systems: $2,200. Income-eligible customers get additional bonuses. Solar + heat pump + battery creates an energy ecosystem that maximizes the value of your investment.
$55/mo Powerwall lease, or up to $10,500 BYOD incentive
Green Mountain Power offers a nationally unique battery program. Lease 2 Tesla Powerwalls (27 kWh) for $55/month with installation included — no upfront cost. Alternatively, their BYOD program pays $850-$950/kW for eligible batteries (max $10,500). Adding a battery to solar increases self-consumption from ~70% to ~90%, reducing dependence on declining net metering credits.
Only way to access any federal credit in 2026
Section 25D (homeowner ITC) is dead. But if a financing company owns the system on your roof via a PPA or lease, they can claim Section 48/48E at 30% for projects beginning construction before July 4, 2026. They pass some savings to you as a below-utility electricity rate. $0 down, immediate savings, 30% federal tax credit in the deal — but you don't own the system.
Honest about the headwinds. These are real challenges, not manufactured doubt.
Zero dollars in federal tax credit for homeowner cash or loan purchases. A 30% credit on $25,600 would have been $7,680 — now gone.
Vermont is unique among Northeast states in having never offered a direct state solar rebate. No SMART program, no REF rebate, no Energize program for solar.
Without state incentives or federal ITC, VT payback is 12-13 years — longer than MA (7-8 yrs), RI (8-9 yrs), NH (9.5 yrs), or CT (8-9 yrs).
GMP rates average $0.22/kWh — meaningful, but lower than MA ($0.28-0.32), CT ($0.27), or RI ($0.29). Lower rates mean slower payback.
VT PUC has reduced net metering rates seven years in a row. Every year you wait, you lock in a lower rate for 10 years. Virtual net metering is completely gone (H.289).
Vermont averages ~4.0 peak sun hours/day in PVWatts modeling — less than southern states, requiring slightly larger systems for the same production.
All solar installations in Vermont must obtain a Certificate of Public Good from the VT PUC. This adds 4-8 weeks to the permitting process and ~$200-500 in fees.
Your utility significantly changes the economics. Here is how solar pencils out across Vermont's three main utilities.
| Utility | Market Share | Rate | 8 kW Annual Savings | 8 kW Payback | Notes |
|---|---|---|---|---|---|
| Green Mountain Power (GMP) | ~75% | $0.2146/kWh | $2,060 | ~12.4 yrs | Battery program, TOU rate option |
| Vermont Electric Cooperative (VEC) | ~10% | $0.2348/kWh | $2,254 | ~11.4 yrs | Rural northern/eastern VT, 32K+ members |
| Burlington Electric (BED) | ~5% | $0.1837/kWh | $1,764 | ~14.5 yrs | 100% renewable since 2014. Lowest rate. |
Vermont's 6% sales tax exemption on solar equipment, labor, and batteries is scheduled to expire June 30, 2026. After that date, you'll owe an extra $1,536 on a typical 8 kW system at current prices. This is a real legislative deadline — not a promotional countdown. Systems need to be contracted and installed before June 30 to capture this savings.

Answers to the most common questions Vermont homeowners ask about going solar.
Yes, but with important caveats. Vermont has the longest solar payback in New England at 12-13 years due to no state incentives, no federal ITC, and lower-than-average electricity rates ($0.22/kWh GMP avg). The 25-year economics are still strongly positive — an 8 kW system yields $35,000-$45,000 in lifetime savings. You should consider solar if: you plan to stay in your home 15+ years, you have a south-facing roof, and you are a GMP or VEC customer. The sales tax exemption expires June 30, 2026, adding $1,536+ in cost after that date.
The payback period for Vermont solar in 2026 is approximately 12-13 years for a cash purchase. An 8 kW system costs roughly $25,600 (8,000 W × $3.20/W). Annual production is ~9,600 kWh (8 kW × 1,200 kWh/kW/yr). At GMP's $0.22/kWh average rate with ~70% self-consumption and 30% export at the net metering rate, annual savings total approximately $2,112. That gives a simple payback of $25,600 ÷ $2,112 ≈ 12.1 years. After payback, you have 12+ years of near-free electricity.
Vermont has three active incentives for solar in 2026: (1) Sales tax exemption — 6% off equipment, labor, and batteries, saving ~$1,536 on a typical 8 kW system. This expires June 30, 2026. (2) Property tax exemption — systems under 50 kW are exempt from property tax assessment, saving ~$400/year. (3) Category I net metering — a positive adjustor of ~$0.04/kWh above the blended rate, locked for 10 years. There is NO state solar rebate and NO federal residential ITC (Section 25D expired Dec 31, 2025). The only way to access federal incentives is via a PPA or lease (Section 48/48E at 30%, deadline July 4, 2026).
It depends on your time horizon and electricity usage. Without the 30% ITC, the payback stretches to 12-13 years. If you plan to stay 15+ years, the 25-year savings ($35K-$45K) far exceed the cost. The sales tax exemption (save $1,536 now, expires June 30), property tax exemption ($10,000 over 25 years), and net metering still make the math work — just more slowly than when the ITC was available.
Your utility significantly impacts solar payback. GMP customers ($0.2146/kWh, ~75% of VT) see ~12.4-year payback. VEC customers ($0.2348/kWh, northern/eastern VT) see a shorter ~11.4-year payback. BED customers in Burlington ($0.1837/kWh — lowest rate, 100% renewable already) see the longest payback at ~14.5 years. If you're a BED customer, solar economics are weakest in the state. Higher rate utilities (VEC) are where solar makes the most financial sense.
Vermont exempts solar equipment, installation labor, and battery storage from the state 6% sales tax. This saves approximately $1,536 on an 8 kW system ($25,600 gross × 6%). The exemption is currently scheduled to expire June 30, 2026. Systems installed after that date will owe the 6% sales tax, adding $1,500-$2,000+ to the system cost depending on size. This is a real deadline — not marketing hyperbole.
The GMP battery program (lease 2 Powerwalls for $55/month or BYOD incentive up to $10,500) is genuinely valuable for solar customers. Adding a battery increases self-consumption from ~70% to ~90%, reducing dependence on net metering credits. With VT's declining net metering rates, maximizing self-consumption becomes more important each year. The $55/month lease costs $6,600 over 10 years but includes installation, maintenance, and firmware updates — plus backup power during outages. The economics improve as net metering rates continue to decline.
No. Virtual net metering in Vermont was phased out by H.289, effective January 1, 2025. No new virtual net metering arrangements are permitted. Community solar is effectively dead for new projects as a result. If you want solar credits, you must have panels on your own property (rooftop or ground-mount with CPG approval).
