Need to know
- We rated 5 Vermont solar companies on licensing, warranties, local presence, track record and options. The top three: Catamount Solar (4, Very good), Green Mountain Solar (3.5, Good) and SunCommon (3.5, Good).
- Vermont credits extra solar power at your utility’s rate or 20.71 cents per kWh, whichever is lower, minus a 5-cent siting charge on every kWh a new system makes. The charge is fixed by the date your complete application is filed, so ask when your installer will file.
- A company that signs a home solar contract of $10,000 or more must hold an OPR residential contractor registration. Vermont does not license electrical companies, and state law needs no electrician’s license in a one- or two-family home, so ask who wires your system.
What solar costs in Vermont
Gross price before incentives. There is no federal credit for owner-purchased systems completed after December 31, 2025, and Vermont has no state solar tax credit. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.

Solar incentives, tax breaks and rebates in Vermont
- Net metering
- Extra power earns your utility's residential rate or 20.71 cents per kWh, whichever is lower. A new system of 15 kW or less pays a 5-cent siting charge, which leaves about 15.71 cents.

- Complete applications filed on or after August 1, 2026 carry the 5-cent siting charge for the life of the system; those filed August 1, 2024 to July 31, 2026 carry 4 cents.
- RECs
- If you keep your renewable energy credits, you pay 4 cents per kWh more on all the power you make, about $276 a year for a typical system.
- Sales tax
- No 6% Vermont sales tax on net-metered solar equipment if you give the seller Form S-3E at or before the sale (32 V.S.A. § 9741(46)). It has no end date.

- A net-metered home system under 50 kW, and a home battery under 600 kWh, is exempt from education and municipal property tax. There is nothing to file.

Who qualifies, deadlines and sources: Vermont solar incentives.
What to check with your utility
Green Mountain Power
- Extra power earns 20.71 cents per kWh before the 5-cent siting charge, about 15.71 cents for a new system.
- Bring Your Own Device pays up to $10,500 upfront for an owned battery on GMP's list, used at peak times for 10 years, with a $3.97 monthly software fee.
- GMP also leases two Tesla batteries for $55 a month for 10 years, or $5,500 paid once.
Vermont Electric Co-op
- Same 20.71-cent base credit, about 15.71 cents per kWh after the siting charge.
- Its battery program pays a monthly bill credit, or an upfront payment plus a smaller credit, for a battery of at least 10 kWh.
- Credits cannot pay the customer charge or the energy efficiency charge.
Burlington Electric
- The base credit is about 16.59 cents per kWh, about 11.59 cents after the siting charge.
- Ask for a quote built on Burlington Electric rates, not Green Mountain Power figures.
Washington Electric Co-op and other utilities
- Washington Electric uses the 20.71-cent base credit, about 15.71 cents after the siting charge.
- Members at or below 185% of the federal poverty level may get a $45 monthly bill credit for five years while spots last.
- Unused credits at every Vermont utility expire after 12 months.
Check the company and its warranty
Three names can appear in one solar deal: the company that sells, the company that signs the contract and the licensed people who do the work. Check that they fit together.
- Contract company: look up its license on the Vermont Office of Professional Regulation (OPR) residential contractor registration, required since April 1, 2023 for home jobs of $10,000 or more, including solar. The Division of Fire Safety licenses electricians as individuals; there is no company electrical license.. The name must match your contract.
- Electrical connection: Vermont licenses master and journeyman electricians, but 26 V.S.A. § 910(6) says no license is required for electrical work in a building with no more than two dwelling units (https://legislature.vermont.gov/statutes/fullchapter/26/015); OPR lists solar installation as residential contracting that needs registration for jobs of $10,000 or more (https://sos.vermont.gov/residential-contractors/residential-contractor-faqs/). Ask who does it.
- Warranty documents: ask for the workmanship warranty, the roof coverage terms and each equipment warranty before you sign.
Before your first sales call, read questions to ask your solar installer and how to read a solar quote.
Compare your Vermont quotes
Ask every company to quote the same basics. Then the differences you see are real.
From quote to permission to operate
Some steps overlap, and timing depends on your town, your utility and equipment supply. Ask each installer for a written schedule for your project.
Proposal and site check
The installer looks at your roof, shading and electrical panel and gives you a written proposal.
You and the installerDesign and applications
After you sign, the installer finishes the design and applies to your utility for the connection.
Installer; you sign the formsPermits and utility review
Your town or county reviews the building and electrical permits. The utility reviews the connection.
Permit office and utilityInstallation and inspection
The crew installs the system. A licensed electrician connects it, and the inspector checks the work.
Installer crew, electrician and inspectorPermission to operate
The utility approves the system and updates your meter if needed. Turn the system on only after this step.

How we rate Vermont solar companies
Each company gets up to 100 points from facts anyone can check: its own website and Vermont’s public license records, read October 14, 2026. Facts a company does not publish earn no points. No company pays for its rating, and we do not use customer star reviews.
- Licensing (30 points): an active state license, a licensed electrician and license numbers printed on its website.
- Warranty protection (35 points): workmanship warranty length, roof-penetration coverage in writing and any production guarantee.
- Local presence (15 points): an office in Vermont and Vermont named as a service area.
- Track record (10 points): years installing solar.
- Options (10 points): batteries and the number of ways to pay.
Stars: 85 points or more is 5 (Top-rated), 72 is 4.5 (Excellent), 60 is 4 (Very good), 45 is 3.5 (Good), below 45 is 3 (Average). We did not inspect installations, collect customer quotes or test customer service.
Vermont solar company FAQs
How do I check a Vermont solar installer?
Search the company on the Office of Professional Regulation’s Find a Professional lookup. A company that signs home contracts of $10,000 or more must hold an active residential contractor registration, unless licensed tradespeople do the work. Ask which licensed electrician will wire your system, and read the written workmanship warranty before you sign.
Does Vermont have net metering?
Yes. Every Vermont utility credits extra solar power at its residential rate or 20.71 cents per kWh, whichever is lower. A new system of 15 kW or less pays a 5-cent siting charge on every kWh it makes, which leaves about 15.71 cents. Burlington Electric credits about 16.59 cents before the charge. Unused credits expire after 12 months.
Is there a Vermont solar tax credit?
No. Vermont has no state credit for installing home solar, and the federal credit ended for owner-purchased systems completed after December 31, 2025. Vermont’s help comes as bill credits, no sales tax on solar equipment when you give the seller Form S-3E, and no property tax on a net-metered home system under 50 kW.
Can I get paid for a home battery in Vermont?
Green Mountain Power pays $850 to $950 per kW of battery power, up to $10,500 upfront, if you let it use a battery you own at peak times for 10 years. The program runs until September 30, 2028. Vermont Electric Co-op pays a monthly credit, or a smaller upfront payment, for batteries of at least 10 kWh.
