Need to know
- We rated 8 New Hampshire solar companies on licensing, warranties, local presence, track record and options. The top three: Granite State Solar (4, Very good), ReVision Energy (3.5, Good) and Venture Home (3, Average).
- Eversource, Liberty and Unitil credit extra solar power at the supply and transmission rates plus 25% of distribution, under rules that run to December 31, 2040. If community power or another supplier sells your power, the credit drops, so check the supply line on your bill.
- New Hampshire has no home improvement or solar contractor license. A licensed electrician must make the electrical installation, and a company can hold an electrical license only with a licensed master electrician in charge. Check both on the OPLC lookup before you sign.
What solar costs in New Hampshire
No federal credit for systems you own, no state rebate and no state income tax to hang a credit on: the gross price is the net price. Batteries and roof work cost extra. Compare each quote’s price per watt with these numbers.

Solar incentives, tax breaks and rebates in New Hampshire
- Net metering
- Eversource, Liberty and Unitil credit extra solar power at the supply and transmission rates plus 25% of distribution, about 23.04 cents per kWh at Liberty's rates, under rules that run to December 31, 2040.
- Your power supplier
- If a community power program or another supplier sells your power, the utility credit falls to about 7.2 cents per kWh at Liberty's rates.
- Electric co-op
- New Hampshire Electric Cooperative credits 14.662 cents per kWh for every kWh you send out (rates since August 1, 2026).
- Cash for credits
- Credits roll forward each month; you can ask for a payment when the balance is above $100 at the end of March.
- Property tax
- Towns that adopted RSA 72:62 exempt some or all of the system's value; apply to your assessor on Form PA-29 by April 15.
- Battery incentive
- Eversource pays $230 per kWh of battery capacity, up to $3,000, for an approved Enphase or FranklinWH battery enrolled in demand response for three years.
- Sales tax
- New Hampshire has no general sales tax, so solar equipment carries none.

- Federal credit
- The federal tax credit ended for systems finished after December 31, 2025.

What to check with your utility
Eversource
- Extra power earns the supply and transmission rates plus 25% of distribution, under rules that run to December 31, 2040.
- Eversource pays $230 per kWh of battery capacity, up to $3,000, if you enroll an approved Enphase or FranklinWH battery for three years.
- Eversource customers can borrow $1,000 to $10,000 at 0.00% APR for an approved battery while loan money lasts.
Liberty Utilities
- At Liberty's rates, extra power earns about 23.04 cents per kWh, against 28.74 cents you pay per kWh.
- On community power or another supplier, the credit falls to about 7.2 cents per kWh.
- Liberty charges $200 to connect a system up to 25 kW, and its own battery program is closed to new applicants.
Unitil
- Unitil uses the same credit formula as Eversource and Liberty; ask your installer to show the three rates from your own bill.
- The Eversource battery incentive does not apply to Unitil customers.
New Hampshire Electric Co-op net metering
- NHEC credits 14.662 cents per kWh for every kWh you send out and does not net your use over the month.
- The $29.00 monthly member charge stays, and rates change several times a year.
- NHEC wants its application filed before any equipment is bought.
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 New Hampshire electrical licenses from the Electricians' Board (Office of Professional Licensure and Certification, OPLC). Companies hold an Electrical Corporation license (numbers end in C) with a licensed master electrician in charge. New Hampshire has no statewide home improvement or solar contractor license.. The name must match your contract.
- Electrical connection: New Hampshire law says no electrical installation may be made for pay unless by an electrician or other person licensed by the OPLC, and a company may be licensed only if an officer or employee in charge is a licensed master electrician (RSA 319-C:1 and 319-C:10: https://gc.nh.gov/rsa/html/XXX/319-C/319-C-1.htm, https://gc.nh.gov/rsa/html/XXX/319-C/319-C-10.htm). 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 New Hampshire 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 New Hampshire solar companies
Each company gets up to 100 points from facts anyone can check: its own website and New Hampshire’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 New Hampshire and New Hampshire 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.
New Hampshire solar company FAQs
How do I check a New Hampshire solar installer?
New Hampshire has no home improvement or solar contractor license. Search the company on the OPLC license lookup for an active Electrical Corporation license, whose numbers end in C, and ask which master electrician pulls the permit. The name on the license should match the company on your contract.
Does New Hampshire have net metering?
Yes. Eversource, Liberty and Unitil credit extra solar power each month at the supply and transmission rates plus 25% of distribution, about 23.04 cents per kWh at Liberty’s rates. The rules run to December 31, 2040. New Hampshire Electric Cooperative credits 14.662 cents for every kWh you send out.
Is there a New Hampshire solar rebate or tax credit?
No. Senate Bill 303 of 2024 repealed the state rebate for home solar, and New Hampshire has no income tax for a credit to reduce. The federal credit ended for owned systems finished after December 31, 2025. Some towns exempt solar from property tax if you apply by April 15.
Does community power change my solar credit?
Yes. If a community power program or another supplier sells your power, your utility credits only transmission and 25% of distribution, about 7.2 cents per kWh at Liberty’s rates instead of about 23.04 cents. The Community Power Coalition recommends that net metered homes stay on the utility’s default supply.
