New Hampshire solar incentives, honestly explained (2026)

New Hampshire’s solar pitch is refreshingly blunt: the Granite State offers no income-tax credit (there is no income tax), no production payments, and a modest rebate — and solar still works here for one overpowering reason: electricity in New Hampshire is among the most expensive in America. Every kilowatt-hour your roof produces replaces power costing roughly 22 cents and climbing. This guide gives Granite Staters the honest version: real costs, how the statewide net metering rules actually credit you, the rebate and the town-by-town tax exemption, and when solar genuinely makes sense here.

What solar costs in New Hampshire in 2026

New Hampshire pricing runs about $3.05 per watt as of mid-2026 — a typical 8.8 kW system lands around $26,800 before incentives, with real quotes from roughly $23,000 to $31,000. Two structural advantages: New Hampshire charges no sales tax, so your quote is your quote; and installation competition across the southern tier keeps pricing honest. The recurring 2026 warning applies here with full force: the federal solar tax credit expired at the end of 2025 — any New Hampshire quote still showing a 30% federal line is fiction worth thousands.

How New Hampshire net metering actually works

New Hampshire requires its regulated utilities — Eversource, Unitil and Liberty Utilities — to net metered solar for systems up to 100 kW. In practice: production offsets your own usage at full retail value month by month, and monthly surplus carries forward as a credit near the utility’s default energy-service rate — most of retail, but not all of it. The honest design consequence: systems sized to your real annual usage beat oversized exporters in New Hampshire. The New Hampshire Electric Co-op sets its own member policies, so co-op households should confirm current terms directly.

The rebate and the tax exemptions, honestly

The state’s residential renewable rebate pays $200 per kilowatt up to $1,000 — real money, with an honest caveat: the program runs on funding cycles and frequently carries a waitlist, so treat it as a bonus, not a plan, and let your installer manage the application. On property taxes, New Hampshire runs a local-option exemption: each town chooses whether solar’s added value is exempt from local property taxation, and many — including Concord, Exeter and Dover among others — have adopted it. In one of America’s heaviest property-tax states, one call to your assessor’s office settles a twenty-year question.

Is solar worth it in New Hampshire?

Honestly: usually yes, on rate strength alone. With retail power around 22¢/kWh and a history of sharp winter-peak pricing, a well-oriented New Hampshire roof pays back in roughly 9–12 years and then produces decades of protected power — typically $60,000–$85,000 of 25-year savings. The honest caveats: heavy shade from New Hampshire’s forests, aging roofs that should be replaced first, seasonal properties that need honest sizing, and towns without the tax exemption where the assessor question deserves asking before signing. For everyone else, waiting mostly means donating more winters to the utility.

Next steps for Granite State homeowners

The honest path is the same one we recommend everywhere: understand your real numbers before anyone quotes you, then get a quote when you actually want one. For New Hampshire that means confirming three things upfront — your utility (Eversource, Unitil, Liberty or the co-op), your town’s property-tax exemption status, and the current rebate funding cycle — because those three details move your math more than any brochure. We will give you a free, no-pressure estimate for your New Hampshire home with all of it built in, reviewed by a real person, with no call-center follow-up and no handing your number to seven installers. And if solar does not fit your home, we will say exactly that.
