New Hampshire solar incentives in 2026
Last updated · every NH program below is verifiable against the sources at the foot of this page.
The most valuable solar incentive in New Hampshire right now is State residential rebate (limited funding cycles). Overall, the state's incentive stack rates as moderate compared with the rest of the country.
The federal credit is gone — start here
The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025. If you are buying a system in New Hampshire this year, there is no federal credit. That is a roughly $8,640 swing on an $28,800 system compared with 2025 pricing, and it is why state programs matter more now than they did a year ago.

New Hampshire solar tax credit
There is no New Hampshire solar tax credit in 2026, and no federal one either — Section 25D ended for systems installed after December 31, 2025. What New Hampshire does offer on the tax side is property tax exemption, covered below.
New Hampshire solar rebates and grants
Small residential system rebate; funding is limited and lapses. Rebate and grant programs are funding-limited and have opened and closed mid-year before, so confirm the current round is open before counting on it.
New Hampshire’s state rebate program for small residential systems has operated with limited funding cycles; check current availability.
Net metering and export rates in New Hampshire
New Hampshire uses a net billing tariff: exports are credited at the full energy and transmission portion of the rate but not all distribution charges — close to, but below, retail.
Compare this with net metering in every other state.
Export rules deserve to be read as an incentive. In a retail net metering state, every exported kilowatt-hour is worth the full retail rate; under net billing or avoided-cost compensation, the same kilowatt-hour can be worth a third of that. For a New Hampshire home at an assumed $0.28/kWh, that difference compounds across a 25-year system life.
What this means for your numbers
A typical 8 kW system in New Hampshire costs roughly $22,400–$28,800 installed before incentives, producing about 9,440 kWh a year and saving around $2,178 in year one — a simple payback near 10–13 years with no incentives applied. Anything in the table above shortens that.
Frequently asked questions
What are New Hampshire solar tax credits worth in 2026?
New Hampshire offers no residential solar income tax credit in 2026, and the 30% federal credit ended for systems installed after December 31, 2025. What remains on the tax side is property tax exemption, which lower cost indirectly rather than paying you back.
Does New Hampshire have solar rebates?
Yes. Small residential system rebate; funding is limited and lapses. Rebate programs in NH are funding-limited and have historically opened and closed mid-year, so confirm the current round is still accepting applications before you count the money.
Is there a New Hampshire solar property tax exemption?
Yes. New Hampshire excludes the value solar adds to a home from property tax assessment, so a system that raises your home's value does not raise your annual tax bill.
What solar incentives are available in New Hampshire in 2026?
New Hampshire’s state rebate program for small residential systems has operated with limited funding cycles; check current availability. Because the federal Section 25D credit ended for systems installed after December 31, 2025, these state, local and utility programs are now the entire incentive picture for a purchased system.
Is there still a 30% federal solar tax credit in New Hampshire?
No. The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Any quote or website still applying 30% to a 2026 purchased installation is out of date. Leased and PPA systems can still benefit indirectly, because the third party that owns the system may claim the commercial 48E credit through 2027 and pass some of the value through in pricing.
Does New Hampshire have net metering?
New Hampshire uses a net billing tariff: exports are credited at the full energy and transmission portion of the rate but not all distribution charges — close to, but below, retail. Export rules are effectively an incentive — often the largest one — because they set what every kilowatt-hour you do not use on site is worth.
How much do incentives change the cost of solar in New Hampshire?
Before incentives, a typical 8 kW system in New Hampshire runs roughly $22,400–$28,800. Small residential system rebate; funding is limited and lapses — the value depends on current funding. See our full New Hampshire cost breakdown for payback math.
