The federal homeowner tax credit is dead. But a third-party financing company can still capture the 30% ITC under Section 48/48E and pass those savings to you through lower lease or PPA payments — with $0 down.
Deadline: Projects must begin construction before July 4, 2026
Vermont's average electric rate of $0.22/kWh is lower than Massachusetts ($0.33) and Connecticut ($0.30), which means the savings margin on a solar lease or PPA is narrower. A PPA at $0.10-$0.16/kWh still saves $0.06-$0.12 per kWh from day one, but the payback is longer than in high-rate states.
However, three factors make TPO solar compelling in Vermont right now:
$0.22/kWh

$0.10-0.16

ITC Deadline
The federal residential solar tax credit (Section 25D) expired on December 31, 2025. If you buy solar with cash or a loan in 2026, you get $0 back from the IRS. But Section 48/48E provides a 30% credit to the entity that owns the solar system. A financing company owns the panels on your roof, claims the credit, and passes savings to you through lower payments.
A financing company (the "third-party owner") purchases and installs solar panels on your roof. You don't buy the system — you agree to either lease it (fixed monthly payment) or buy the power it produces (PPA, per-kWh rate).
Because the financing company legally owns the system, it files IRS Form 3468 and claims the 30% Investment Tax Credit under Section 48/48E. On a $30,000 system, that's $9,000 back from the IRS. The company also claims MACRS depreciation (5-year accelerated schedule + 20% bonus in 2026).
The financing company doesn't pocket the ITC — it uses the $9,000+ in tax benefits to reduce your monthly payment. This is why lease/PPA payments are typically 20–40% lower than what you'd pay on a standard solar loan without the ITC.
Your lease/PPA payment is locked in below your current electric bill rate. You save money starting month one. The system owner handles all maintenance, monitoring, and warranty claims.
With NuWatt's Propel program, the third-party owner transfers full ownership to you at year 5 — after the ITC recapture period expires. You get the best of both worlds: ITC savings upfront, full ownership long-term.
Important Distinction
The financing company claims the ITC — not the installer, not the homeowner. The installer is a contractor. The financing company is the legal owner of the system and the entity that files IRS Form 3468. This is the intended design of the tax code, not a loophole.
Here is exactly what the financing company captures on a Vermont solar system and how the deadline works.

Longest payback in New England due to lower VT rates and $0 ITC.
Monthly payment may exceed utility savings in early years at VT rates.
Fixed monthly payment. ITC savings baked into lower rate.
Pay per kWh produced. At $0.10-$0.16, you save $0.06-$0.12/kWh vs. GMP.
Propel Is Not Available in Vermont
NuWatt's Propel program (TPO for years 1-5, ownership transfer at year 5) is currently available in Maine and Texas only. Vermont's CPG requirements and regulatory environment may affect the Propel expansion timeline. Standard leases and PPAs remain the best $0-down options in VT today.
Add-On: GMP Battery Lease ($55/mo)
Stack a GMP Powerwall lease alongside your solar lease or PPA. These are separate agreements that complement each other: the solar handles electricity generation while the battery handles peak-demand events, backup power, and TOU arbitrage. BYOD option available at $850-$950/kW for customers who already own a battery.
The Vermont Public Utility Commission has reduced net metering compensation rates for 7 consecutive years. Every year you delay going solar, the economics worsen. Locking in a TPO rate now is the best hedge against continued NM degradation.
Vermont uses a Category I-IV net metering system. Residential rooftop systems fall under Category I (up to 15 kW). Each category has a blended rate plus or minus an “adjustor” set by the VT PUC.
Category I (Residential)
Up to 15 kW. Still has a positive adjustor, meaning exported solar earns slightly above the blended rate. But this adjustor has been cut every year and is shrinking toward zero.
7 Consecutive Cuts
The VT PUC has reduced the NM adjustor every year for 7 straight years. The trend is clear: exported solar is worth less each year. Signing a TPO agreement now locks in today's rates for the contract term.
Community Solar Is Dead in Vermont
H.289 killed virtual net metering for new community solar projects. Rooftop solar (Categories I-II) remains viable, making individual TPO agreements even more important for homeowners who want solar with $0 down.
Lock Your Rate
A 25-year PPA at $0.10-$0.16/kWh protects you from both utility rate increases AND declining net metering value.
Shrinking Window
Section 48/48E expires July 4, 2026. Combined with declining NM rates, 2026 offers the last strong TPO economics in Vermont.
Hedge Your Risk
Even if NM adjustors hit zero, your PPA/lease payment stays the same. The TPO company absorbs the regulatory risk, not you.
Green Mountain Power offers the most aggressive residential battery program in New England. Stacking a GMP battery with your solar lease or PPA unlocks demand-response income and TOU arbitrage that no other state can match.
$55/month
$850-$950/kW incentive
GMP's Time-of-Use (TOU) rates create a significant spread between peak and off-peak pricing. With a battery, you charge during off-peak hours and discharge during peak hours, capturing the difference.
Peak Rate
$0.3407
per kWh
Off-Peak Rate
$0.1452
per kWh
TOU Spread
$0.1955
per kWh arbitrage
A 13.5 kWh Powerwall cycling 80% daily captures roughly $2-$3 per day in TOU arbitrage during peak months. Combined with demand-response event payments, this adds $500-$800 per year in value on top of your solar lease savings.
We believe in honest solar advice. Vermont has real advantages for TPO solar, but there are challenges specific to this state that you should understand before signing.
$0 down — no upfront cost in a state with high install costs ($3.05/W)
30% ITC captured by financing company under Section 48/48E, lowering your payment
All maintenance, monitoring, and warranty handled by system owner
GMP battery program stacks with solar lease for additional demand-response income
No property tax increase for systems under 50 kW
Sales tax exemption (6%) reduces total system cost for TPO provider
Lower electric rates ($0.22/kWh) mean narrower savings margin vs. high-rate states
Net metering adjustor has been cut 7 consecutive years — declining export value
CPG requirement adds 2–4 weeks to project timeline
VT PUC regulatory environment creates uncertainty for long-term NM value
Fewer national TPO providers operate in VT — more limited lease/PPA options
Typical 2–3% annual escalator may outpace VT's historically moderate rate increases
Every solar installation in Vermont requires a Certificate of Public Good (CPG) from the VT Public Utility Commission. This adds 2-4 weeks to the project timeline. Your TPO provider handles the CPG application, but factor this into the July 4, 2026 deadline.
H.289 killed virtual net metering for new community solar projects in Vermont. If your roof is not suitable for solar, your options are limited. For homes with good roof exposure, individual rooftop TPO remains the primary $0-down pathway.
At $0.22/kWh and $0 federal ITC, cash-purchase payback in Vermont is approximately 13 years — the longest in New England. This actually strengthens the case for TPO: why tie up $30,500 for 13 years when a lease gives you day-one savings with $0 down?
Vermont offers a 6% sales tax exemption on solar equipment and a 100% property tax exemption for systems under 50 kW (32 V.S.A. §3802). Both exemptions benefit TPO arrangements because they reduce the system owner's total cost, which flows to you as lower payments.
Critical Deadline
The One Big Beautiful Bill Act (OBBBA) requires projects to begin construction before July 4, 2026 for the third-party owner to claim the 30% ITC. After this date, the credit may be eliminated or significantly reduced. Factor in Vermont's CPG requirement (2-4 weeks) plus standard permitting (4-6 weeks) and start the process by early spring 2026 at the latest.
Battery Deadline
If you plan to pair your solar lease with GMP's Bring Your Own Device battery program, the current enrollment window closes September 30, 2026. The $850-$950/kW incentive rate may change after this date.
Not as a homeowner. The federal residential credit (Section 25D) expired December 31, 2025. But if a third-party financing company owns the system on your roof via a lease or PPA, that company claims the 30% ITC under Section 48/48E. The savings are passed to you through lower monthly payments.
Vermont's $0.22/kWh rate is lower than neighboring states, which narrows the savings gap. A PPA at $0.10–0.16/kWh still saves $0.06–0.12 per kWh from day one. Over 25 years, that adds up to $15,000–$22,500. The key advantage: you get solar with $0 down and the TPO company captures the 30% ITC that you'd otherwise lose entirely.
Vermont uses a Category I–IV net metering system with a blended rate plus or minus an adjustor. For residential systems (Category I, ≤15 kW), the adjustor is still positive but has been cut by the VT PUC for 7 consecutive years. This means exported solar power earns slightly above retail today, but the value is declining. Ask your TPO provider how declining NM rates factor into the 25-year savings projection.
A Certificate of Public Good (CPG) is required for all net-metered solar systems in Vermont. It's issued by the VT Public Utility Commission and typically adds 2–4 weeks to the installation timeline. Your TPO provider handles the CPG application as part of the installation process — no action needed from you.
Yes. Green Mountain Power's battery program (Bring Your Own Device or leased Powerwall) is compatible with solar leases and PPAs. The battery provides demand-response income and backup power. The solar lease handles your electricity generation while the GMP battery handles peak-demand events. These are separate agreements that complement each other.
Not yet. NuWatt's Propel program is currently available in Maine and Texas. Standard solar leases and PPAs are available in Vermont today. Vermont's CPG and regulatory environment may affect the timeline for Propel expansion to VT.
Vermont's average cost of $3.05/W is higher than the national average due to smaller installer market, rural terrain, shorter construction season, and CPG permitting requirements. This actually makes TPO more attractive — you avoid the high upfront cost entirely and the financing company absorbs the per-watt premium.
The critical deadline is July 4, 2026. The third-party system owner must begin construction before this date to claim the Section 48/48E 30% ITC. Factor in Vermont's CPG requirement (2–4 weeks) plus standard permitting (4–6 weeks) and start the process by early spring 2026 at the latest.
