Granite State Solar, ReVision Energy and Venture Home are the three installers in our vetted New Hampshire network for 2026. In a three-company market you cannot average out a weak proposal against six others, so each one has to be interrogated on business structure, not just price.
New Hampshire installer coverage, state electrical licensing, and federal credit status reviewed August 2026.
In a state with three serious residential installers, the usual advice to “get five quotes and let competition sort it out” does not work. New Hampshire’s bench is short, drive times are long, and in parts of the state you will reach two companies, not five. That changes the job: you cannot average out a weak proposal against six others, so each one has to be interrogated rather than compared.
What separates companies here is not price per watt. It is whether the company will still be answering the phone in year twelve, and whether the crew serving your address is based in New Hampshire or three hours away in another state.
The Granite State Bench Check
The three companies below are structurally different businesses, and the structure is the thing to evaluate. Each trades something away.
Company | Business structure | What that buys you | What it costs you |
|---|---|---|---|
Granite State Solar | New Hampshire only | Knows your town’s inspector and your utility’s interconnection habits as routine work | A small company can be stretched thin in a busy season, and the warranty is only as durable as the business |
ReVision Energy | Employee-owned, three-state regional | Enough scale to carry a service department a decade out, and salespeople who are not on a pure commission pipeline | Your project competes for crew time with projects in Maine and Massachusetts |
Venture Home | Multi-state Northeast | More financing structures and a larger support organization behind the warranty | The person selling may not be the person installing, and service can route through a call center |
There is no right answer in that table. There is only the answer that matches how long you intend to own the house and how much you value a local crew over a financing menu.
Who Actually Covers New Hampshire, Ranked
Ordered by depth of New Hampshire-specific operating experience, which is the criterion this page argues matters most in a thin market. Ranking is not influenced by any commercial relationship, and no company pays for placement or position.
Granite State Solar
The entire business is this state. In a market where local permitting knowledge and interconnection familiarity are the scarce resources, that focus is the differentiator.
ReVision Energy
An employee-owned certified B Corporation working Maine, New Hampshire and Massachusetts, with the longest regional track record of the three. Employee ownership changes the incentive behind a sales conversation.
Venture Home
Northeast coverage with a whole-home approach pairing solar and storage. Formerly Venture Solar, so its record appears under both names. Ask where the nearest service crew to your address is based.
Placement is not a recommendation to sign. It means the company is a genuine residential installer whose New Hampshire presence we verified on its own website.
The Two-Quote Problem
In most states, a bad proposal is exposed by the three sitting next to it. In parts of New Hampshire there is no third proposal, and that is the specific risk here.
With only two quotes, the anchor becomes whichever number arrived first, and a homeowner has no way to tell whether both are high. The defense is not to wait for a bidder who may not exist in your county. It is to make each proposal defend itself in writing:
- The cash price beside the financed price for the identical system. A dealer fee inside a low advertised rate is the most common way a New Hampshire quote quietly gets more expensive.
- What the model assumes about excess generation. New Hampshire does not credit every exported kilowatt-hour at full retail, so a savings model that values all production identically overstates the result. The program terms are in our guide to New Hampshire solar incentives.
- Snow load and roof condition findings, written down. A roof with under ten years of life should be replaced first; removing and resetting an array later is a four-figure cost no proposal carries.
- Who honors the workmanship warranty in year twelve, and what happens to that obligation if the company is sold.
If a company will not put those in writing before the contract, the shortage of alternatives is not a reason to accept it.
Verifying a New Hampshire Installer
New Hampshire does not issue a solar-specific contractor license. The electrical work on a photovoltaic system must be performed under a New Hampshire electrical license, so ask which licensed electrician is attached to your job and confirm the license is active before paying a deposit.
Then ask whether the crews are employed or subcontracted, and where they are based. For an out-of-state company, the distance between your roof and the nearest service crew is the number that matters in year eight, not the number on the proposal.
Benchmark the price against what solar costs in New Hampshire, and settle the underlying question with whether solar is worth it in New Hampshire.

How We Rank Solar Companies
Rankings are built from what we can verify, never from who pays us. Five weighted factors:
Frequently Asked Questions
Fewer than in neighboring Massachusetts. Our network lists three with a verified New Hampshire presence: Granite State Solar, ReVision Energy and Venture Home. Other installers work here, including crews based in Maine and Massachusetts, so ask any out-of-state company where its nearest service crew sits.
There is no single best. The three in our network are Granite State Solar, ReVision Energy and Venture Home, ordered by depth of New Hampshire-specific operating experience. Homeowners comparing solar installers in NH should weigh business structure as heavily as price, because in a thin market the durability of the warranty matters more than a small difference per watt.
New Hampshire does not issue a solar-specific contractor license. Electrical work on a photovoltaic system must be performed under a New Hampshire electrical license. Ask which licensed electrician is attached to the job and confirm the license is active.
Both can do good work. A state-focused company usually knows local permitting and utility habits best; a regional company usually has more service capacity a decade out. Decide based on how long you intend to own the home and whether you value a local crew over a wider financing menu.
Not for a system you buy. The federal residential credit ended for installations completed after December 31, 2025. Any 2026 quote for a purchased system that subtracts 30% is using an expired rule and overstates the payback.
Common in parts of the state. Compensate by making each proposal defend itself in writing: cash price beside financed price, the assumed value of exported production, snow-load and roof findings, and who honors the workmanship warranty in year twelve.
