The federal residential solar tax credit is gone. Vermont's excellent 1:1 net metering makes your installer choice more critical than ever. We compared pricing, local expertise, equipment quality, and warranty coverage from five companies actively installing across the Green Mountain State.
The best solar companies in Vermont in 2026 are NuWatt Energy (best overall value and customer service), SunCommon/iSun (best for community-focused solar), and ReVision Energy (best for premium installations and whole-home electrification). With the federal residential ITC expired, choosing an installer who understands Vermont's 1:1 net metering and can design your system to maximize month-to-month credits is critical for maximizing your savings.
We evaluated each installer on eight criteria that matter most for Vermont homeowners in the post-ITC landscape. Companies that understand VT-specific programs and net metering ranked higher because those factors now represent the largest financial advantages available.

Vermont Renewable Energy Standard
The solar landscape shifted dramatically when the One Big Beautiful Bill Act let the Section 25D residential tax credit expire on December 31, 2025. Here is what that means for Vermont homeowners.
The 30% federal tax credit for homeowner-owned solar (Section 25D) expired. There is no longer a $7,000–$10,000 credit to offset your upfront cost on cash or loan purchases. This makes every other savings lever — especially Vermont's net metering and tax exemptions — more important than ever.
Vermont's 1:1 net metering gives you full retail credit for every kWh your panels export. Credits roll month-to-month with no expiration, meaning summer overproduction directly offsets winter bills. An installer who properly sizes your system to maximize these credits can save you thousands over the life of your system.
Vermont's weather means power outages are a real concern. Green Mountain Power offers battery programs that reward homeowners for grid support. Pairing solar with battery storage provides both outage protection and additional financial benefits. Your installer should be able to design an integrated solar-plus-battery system.
With the homeowner ITC gone, lease and PPA programs have become more competitive. Under these arrangements, the third-party system owner claims the Section 48/48E commercial ITC and passes savings to you through lower monthly payments. For homeowners who cannot pay cash, this is now the primary way to access federal incentives.
Bottom Line
In 2025, you could choose almost any installer and still save money thanks to the 30% tax credit. In 2026, your installer's knowledge of Vermont's net metering program, tax exemptions, and ability to design a properly sized system directly determines whether you maximize your investment. In a small state like Vermont, local expertise is not optional — it is essential.
Vermont's limited installer market means every company has a distinct personality. Local expertise, winter service capability, and net metering knowledge separate the best from the rest.

Protect yourself from bad deals. If you encounter any of these warning signs during the sales process, proceed with caution.
Vermont's 1:1 net metering is the single largest financial benefit of going solar in the state. An installer who cannot explain how VT net metering credits work, how they roll month-to-month, or how to size your system to maximize credits lacks the local expertise you need.
Legitimate solar companies encourage you to compare. Vermont is a small market with strong local installers who compete on quality and transparency. Any company that pressures you to sign immediately — especially by claiming a "limited-time discount" — is using a high-pressure tactic. Vermont law allows cancellation of home improvement contracts.
Vermont's rural geography and harsh winters mean your installer needs local service capability. If a panel loosens under snow load or a microinverter fails in January, you need a company that can dispatch a crew quickly — not one that flies technicians in from out of state.
The Section 25D residential solar tax credit expired December 31, 2025. Any installer quoting a 30% homeowner tax credit in 2026 is either uninformed or dishonest. The only way to access the ITC now is through a lease/PPA where the third-party system owner claims Section 48/48E.
Vermont's weather means power outages are common, especially during ice storms and nor'easters. An installer who cannot offer or properly design a battery backup system is leaving you exposed. Ask about Enphase, Tesla Powerwall, or Franklin battery options and whether they have experience with Green Mountain Power's battery programs.
Accurate system design requires detailed roof analysis — orientation, pitch, shading from trees (heavy tree cover is common in Vermont), rafter spacing, snow load considerations, and electrical panel capacity. A quote based solely on your electric bill is likely inaccurate and could lead to costly change orders.
City-specific guides with local pricing, utility rates, and installer recommendations.
The average cost of solar panels in Vermont in 2026 ranges from $3.10 to $3.40 per watt, with an average around $3.25/W before incentives. For a typical 8 kW system, that translates to roughly $26,000. Vermont does not currently offer a state solar rebate, but property tax and sales tax exemptions help reduce the effective cost. Lease/PPA options through companies like Sunrun or NuWatt's Propel program let the third-party owner claim the Section 48/48E commercial ITC, passing savings to you through lower payments.
Yes, Vermont is a strong state for solar despite its northern latitude. Vermont's 1:1 net metering policy is among the best in the country — you receive full retail credit for every kWh your panels export, and credits roll month-to-month with no expiration. The state has an aggressive Renewable Energy Standard targeting 75% renewable energy by 2032. Green Mountain Power (serving ~80% of VT) is one of the most progressive utilities in the nation for solar integration. Combined with electricity rates around $0.22/kWh, solar payback periods typically fall in the 10–14 year range.
Yes, Vermont has one of the best net metering programs in the country. Solar homeowners receive 1:1 retail credit for exported electricity. Credits roll forward month-to-month with no expiration, meaning excess summer production offsets winter electricity costs. There is no cap on system size for residential net metering (up to 500 kW). Green Mountain Power, Vermont Electric Cooperative, and other VT utilities all participate. This generous program is a primary reason solar makes financial sense in Vermont.
Vermont does not currently offer a state-level solar rebate program. Efficiency Vermont focuses its rebates on heat pumps and weatherization rather than solar panels. However, Vermont provides meaningful tax benefits: solar equipment is exempt from the 6% state sales tax, and solar installations are exempt from property tax assessment (your property taxes will not increase despite the added home value). For $0-down options, lease/PPA programs allow the third-party system owner to claim the Section 48/48E commercial ITC, reducing your monthly payments.
Solar payback in Vermont typically ranges from 10 to 14 years depending on your system size, electricity usage, and financing method. Key factors include your utility rate (Green Mountain Power averages $0.22/kWh), system orientation and shading, and whether you finance with cash, loan, or lease. Vermont's excellent 1:1 net metering and tax exemptions improve the economics. After the payback period, you enjoy essentially free electricity for the remaining 15+ years of your system's life, making solar a strong long-term investment even without federal residential tax credits.
While technically possible, going fully off-grid in Vermont is not recommended for most homeowners. Vermont winters are long with shorter days and heavy snow cover, requiring a very large battery bank and oversized solar array to maintain power through December and January. A better approach is grid-tied solar with battery backup: you stay connected to Green Mountain Power for winter reliability while using battery storage for outage protection. GMP even offers programs for battery owners. The combination of 1:1 net metering and battery backup gives you most of the benefits of off-grid with far less risk and cost.
