Roof + Solar Companies in Vermont:
GMP Battery Programs & Savings (2026)
Vermont is one of America's most progressive energy states — targeting 100% renewable electricity by 2030 and backed by Green Mountain Power's industry-leading battery storage programs. GMP's BYOD battery rebate (up to $10,500) and $55/month Powerwall lease are among the best in New England. With solid net metering, a 100% property tax exemption, and 6% sales tax exemption on solar equipment, Vermont homeowners have a meaningful incentive stack even after the federal ITC expired. This guide covers the top-rated companies, how every Vermont incentive works, utility-by-utility details, and realistic savings estimates for 2026.
Vermont's Progressive Energy Landscape and Solar Opportunity
Vermont punches well above its weight in renewable energy. The Green Mountain State is committed to 100% renewable electricity by 2030 (H.289/RES), and Green Mountain Power — which serves 77% of Vermont customers — has become nationally recognized for its innovative battery storage programs. GMP's BYOD battery rebate (up to $10,500) and $55/month Powerwall lease program are among the most aggressive utility battery incentives in the country, reflecting Vermont's strategy of building a distributed, resilient grid.
Vermont homeowners pay above-average electricity rates — approximately $0.22–$0.23/kWh through Green Mountain Power, placing Vermont rates 40–43% above the national average. These elevated rates drive the solar value proposition: every kilowatt-hour your system produces displaces expensive grid electricity. Vermont's farmhouses, colonial-era homes, and mid-century construction are well-suited for roof + solar bundles, and the state's strong net metering program ensures excess production generates meaningful bill credits.
Vermont's solar policy environment is thoughtfully designed. Net metering credits at approximately $0.14/kWh for new GMP customers (the “avoided cost” rate) are lower than full retail-rate crediting, but Vermont compensates with the 100% property tax exemption (25-year duration for systems under 50 kW), 6% sales tax exemption on solar equipment, and the nation's best utility battery programs through GMP. The CPG permitting process streamlines approvals for residential systems under 15 kW.

Vermont Solar Incentives (2026)
Vermont's solar incentives center on net metering, property and sales tax exemptions, and GMP's exceptional battery storage programs. Here's the complete picture for 2026.
Net Metering
~$0.14/kWh (GMP)Up to 500 kWCredits at avoided-cost rate for GMP customers; higher rate for VEC customers
Vermont's net metering program provides credits for excess solar electricity exported to the grid. For new GMP customers, the credit rate is approximately $0.14/kWh (the “avoided cost” or “all-in” rate) — lower than Maine's or New Hampshire's full retail-rate crediting, but still meaningful ongoing value. Vermont Electric Cooperative customers receive a higher rate of 18.116 cents/kWh. Burlington Electric Department customers receive BED-specific rates.
The 500 kW system size limit is extremely generous for residential use — typical home systems are 7–15 kW. Credits roll over month to month, allowing summer overproduction to offset winter bills. Vermont's long summer days mean meaningful summer surpluses for properly-sized systems.

100% Property Tax Exemption
Systems <50 kW25-Year DurationFull exemption on solar-added home value for residential systems — 25 years
Vermont provides a 100% property tax exemption on the value added to your home by solar energy systems up to 50 kW. This exemption lasts 25 years — longer than most other New England states provide. For virtually all residential solar installations (typically 7–15 kW), the full exemption applies. A typical Vermont solar installation adds $15,000–$25,000 to home value; without this exemption, that increase would generate meaningful additional annual property tax cost given Vermont's above-average property tax rates.

6% Sales Tax Exemption
Systems Up to 500 kWVermont's 6% sales tax waived on solar energy systems for residential use
Vermont exempts solar energy systems up to 500 kW from the state's 6% sales tax. This covers panels, inverters, mounting hardware, and associated equipment for virtually all residential installations. On a typical Vermont solar installation with equipment value of $15,000–$20,000, this exemption saves $900–$1,200. The generous 500 kW cap ensures all residential and most commercial systems qualify.

GMP BYOD Battery Rebate
Up to $10,500GMP Customers Only$850–$950 per kW of battery capacity — one of the best battery rebates in New England
Green Mountain Power's Bring-Your-Own-Device (BYOD) program offers GMP customers a rebate of $850–$950 per kilowatt of battery capacity, up to a maximum of $10,500 per household. A typical whole-home battery system (10–13 kWh) would qualify for roughly $8,500–$10,500 in rebates. In exchange, GMP can remotely dispatch your battery during peak grid demand events — a small concession for a substantial rebate. You retain full backup power capability.
Note: This program is subject to enrollment caps and can develop waitlists during high-demand periods. Check GMP's website for current availability and waitlist status before planning your installation around this rebate.

GMP Powerwall Lease
$55/Month2 Tesla PowerwallsGMP Customers OnlyTwo Tesla Powerwalls for $55/month — GMP owns & maintains; you get backup power
GMP's Powerwall lease program provides two Tesla Powerwalls (retail value: $30,000+) for just $55 per month. GMP owns, installs, and maintains the units. You benefit from whole-home backup power during outages and daily battery management. GMP uses the batteries to provide grid services. This extraordinarily low monthly cost makes battery backup accessible to Vermont homeowners who might not otherwise afford a Powerwall purchase.
This program has experienced waitlists due to high demand. Confirm availability and expected installation timeline directly with GMP before planning your project around this program.

Federal ITC Update: Important Change for 2026
The homeowner-claimed federal solar Investment Tax Credit (ITC) expired December 31, 2025. As of 2026, Vermont homeowners who purchase a solar system outright cannot claim the federal 30% ITC on their personal tax return. Solar leases and PPAs continue to benefit from a 30% ITC through Third-Party Ownership rules through 2027 — meaning lease/PPA monthly payments partially reflect this credit. Vermont's full state incentive stack (property tax exemption, sales tax exemption, GMP battery programs) remains fully available in 2026.
Vermont's 100% Renewable Target by 2030
Vermont law (H.289, the Renewable Energy Standard) requires the state to achieve 100% renewable electricity by 2030. This legislative mandate ensures continued strong policy support for residential solar through the end of the decade. Vermont homeowners installing solar today are contributing to — and benefiting from — the state's most ambitious clean energy target in New England.
Vermont Electric Utilities
Vermont has three primary electric utilities, each with distinct service territories, rates, and solar programs. Knowing your utility is essential for understanding your net metering rate and available battery programs.
Green Mountain Power (GMP)
Serves 77% of Vermont: Montpelier, Rutland, St. Johnsbury, Burlington suburbs, and most of central and southern Vermont
Vermont Electric Cooperative (VEC)
Serves the rural Northeast Kingdom: Newport, Derby, Barton, Hardwick, and surrounding northeastern Vermont communities
Burlington Electric Department (BED)
Serves Burlington city only — the largest Vermont city not served by GMP. BED achieved 100% renewable electricity in 2014.
Not sure which utility serves your home? Check your current electric bill. GMP serves most of Vermont. Burlington city residents are served by Burlington Electric Department. Residents of the Northeast Kingdom (Newport, Derby, Barton, Hardwick area) are served by Vermont Electric Cooperative. The GMP BYOD and Powerwall programs are only available to GMP customers — this is an important consideration if you're comparing locations in Vermont.
Vermont Solar Permitting: CPG Process
Vermont uses a unique state-level permitting system through the Public Utility Commission. For most residential systems, this is a simple registration process — not a full review.
Certificate of Public Good (CPG)
Vermont's state permitting framework. Residential rooftop systems under 15 kW use an expedited registration with the Vermont Public Utility Commission — not a full review. Ground-mounted systems under 25 kW also qualify for expedited processing. Your installer files the registration. Most expedited registrations are approved within 2–4 weeks.
Local Building Permit
Vermont municipalities still require local building and electrical permits for solar installations. Turnaround varies by town — typically 2–4 weeks in most Vermont communities. Important: Vermont law (Act 174/Act 38) prohibits local zoning from unreasonably restricting solar installations, so municipalities cannot block compliant rooftop systems.
Utility Interconnection
Your installer files an interconnection application with GMP, VEC, or BED depending on your service territory. GMP and BED typically take 4–8 weeks; VEC may take 6–10 weeks. Your system cannot operate until interconnection approval is complete and a bi-directional net meter is installed.
System Inspection
After installation, your local building inspector and utility conduct final inspections. Most Vermont inspections are completed within 1–2 weeks of installation. Final utility approval triggers net meter installation and you can begin generating NEB credits.
Vermont Solar Zoning Protections
Vermont law (Act 174/Act 38) explicitly prohibits local zoning and land use regulations from unreasonably restricting solar energy systems. Municipal zoning cannot block compliant residential rooftop solar in Vermont. Vermont also has solar access easement provisions allowing homeowners to protect their solar access from future shading by neighboring structures. Historic district design review in Burlington and Montpelier may still apply to exterior modifications in designated areas.
Vermont Solar Costs & Savings (2026)
What does a roof + solar bundle actually cost in Vermont — and what are the realistic savings? Here's what our research shows for Vermont homeowners in 2026.
Battery Storage Changes the Vermont Economics
Vermont's lower electricity rates ($0.22–$0.23/kWh) compared to southern New England mean solar alone has a slightly longer payback period than in Massachusetts or Rhode Island. However, GMP's BYOD battery rebate and Powerwall lease program change the equation significantly. Pairing solar with battery storage — and qualifying for the BYOD rebate — can accelerate the financial case meaningfully by adding a second revenue stream (battery demand response payments) alongside solar bill savings.
Vermont's net metering credit rate of approximately $0.14/kWh for GMP customers means the value of excess production is lower than Maine's 1:1 NEB credits. This makes accurate system sizing more important in Vermont: right-sizing your solar system to minimize excess production (which earns less) while maximizing self-consumption (which displaces $0.22/kWh grid electricity) improves overall economics.
Understanding $0 Down Financing in Vermont
The most common approach for Vermont roof + solar bundles is lease or PPA financing with $0 upfront. You pay monthly for solar production — typically 25–40% below your current GMP, VEC, or BED bill. The roof replacement is bundled into the project. See our guide on how “free roof” financing actually works for a detailed breakdown of these structures.

Vermont Solar FAQ
How does net metering work in Vermont?
Vermont's net metering program credits residential solar customers for excess electricity exported to the grid at the utility's "avoided cost" rate — approximately $0.14/kWh for new systems added by Green Mountain Power customers. This is lower than a full retail-rate credit but still provides meaningful ongoing value. Credits roll over month to month. The program applies to systems up to 500 kW, so virtually all residential systems qualify. Vermont Electric Cooperative customers in the Northeast Kingdom receive a somewhat higher net metering rate of 18.116 cents/kWh. Burlington Electric Department (BED) has its own net metering terms for Burlington city homeowners.
What is Green Mountain Power's BYOD battery rebate?
Green Mountain Power's Bring-Your-Own-Device (BYOD) program offers Vermont homeowners a rebate of $850–$950 per kilowatt of battery capacity, up to a maximum of $10,500 per household. In exchange, GMP can remotely dispatch your battery during peak grid demand events to help balance the grid. You retain full use of your battery for backup power and daily energy management. This is one of the most generous battery storage incentive programs in New England. Note that enrollment is subject to program capacity and can develop waitlists — check GMP's website for current availability.
What is GMP's Powerwall lease program?
Green Mountain Power offers a lease program for two Tesla Powerwalls at $55 per month. GMP owns and maintains the Powerwalls and installs them at your home. You get the benefit of backup power and battery storage without the upfront cost. GMP uses the batteries to provide grid services during peak demand. This program is popular and has experienced waitlists in recent years — interest is high due to the very low monthly cost relative to the retail price of two Powerwalls ($30,000+). Confirm current availability and waitlist status directly with GMP.
Does Vermont have a property tax exemption for solar?
Yes. Vermont provides a 100% property tax exemption on the value added to your home by solar energy systems up to 50 kW in capacity. The exemption lasts for 25 years. For virtually all residential installations (typical residential systems are 7–15 kW), the full exemption applies. A typical Vermont solar installation adds $15,000–$25,000 to assessed home value; without this exemption, that increase would generate hundreds of dollars per year in additional property taxes.
What is Vermont's sales tax exemption for solar?
Vermont exempts solar energy systems from the state's 6% sales tax for systems up to 500 kW. This applies to solar panels, inverters, mounting hardware, and associated equipment. On a typical Vermont solar installation (equipment portion approximately $15,000–$20,000), this saves $900–$1,200. The exemption covers the full residential system, making virtually all home solar installations tax-exempt.
What is Vermont's Certificate of Public Good (CPG) process?
Vermont uses a unique state-level permitting system through the Public Utility Commission (PUC) called the Certificate of Public Good (CPG). For residential rooftop solar systems under 15 kW, the CPG process is a simple expedited registration — not a full review. Your installer files the registration and the system can proceed. Ground-mounted systems under 25 kW also qualify for expedited processing. Larger systems require more formal review. Importantly, Vermont law (Act 174/Act 38) prohibits local zoning from unreasonably restricting solar energy, so municipal zoning cannot block compliant rooftop solar installations.
Is there a federal tax credit for solar in Vermont in 2026?
The homeowner-claimed federal 30% Investment Tax Credit (ITC) expired December 31, 2025. As of 2026, Vermont homeowners who purchase a solar system outright cannot claim the federal ITC on their personal tax return. Solar leases and PPAs continue to benefit from a 30% ITC through Third-Party Ownership rules through 2027, meaning lease/PPA monthly payments partially reflect this credit. Vermont's state incentives (property tax exemption, sales tax exemption, GMP battery programs) remain fully available regardless of federal ITC status.
Which utility serves most of Vermont?
Green Mountain Power (GMP) is Vermont's dominant electric utility, serving approximately 77% of the state's customers. GMP serves most population centers including Montpelier, Rutland, St. Johnsbury, Burlington suburbs, and much of central and southern Vermont. Burlington city is served by Burlington Electric Department (BED), a municipal utility. Vermont Electric Cooperative (VEC) serves the rural Northeast Kingdom region in northeastern Vermont. Your utility determines your net metering rate and available programs — GMP customers have access to the innovative BYOD and Powerwall programs.
How much does a roof + solar bundle cost in Vermont?
A combined roof replacement and solar installation in Vermont typically ranges from $20,000–$40,000 depending on roof size, shingle selection, and desired solar output. Vermont's electricity rates ($0.22–$0.23/kWh through GMP) are lower than Maine's Versant Power or southern New England rates, resulting in slightly longer payback periods (typically 10–14 years for purchased systems). With $0 down lease or PPA financing, most Vermont homeowners see immediate bill reductions of 25–40%. GMP's battery programs can meaningfully improve the financial case.
How do I choose the best solar + roof company in Vermont?
Look for companies with Vermont contractor licensing, solar-specific certifications (NABCEP), experience with GMP, BED, or VEC interconnection depending on your area, strong warranty terms on both roofing and solar, and transparent financing options. Our Vermont best companies comparison ranks the top installers across all these criteria.
