Searching for the New Hampshire solar rebate in 2026? Here’s the straight answer most websites won’t give you: the solar incentive landscape in New Hampshire changed dramatically at the end of 2025, and much of what you’ll read online is outdated. This guide covers exactly what ended, what’s still available, and how to make sure you capture every dollar you’re entitled to.
The Big Change: The Federal Solar Tax Credit Is Gone
For fifteen years, the 30% federal Residential Clean Energy Credit was the backbone of solar savings. Under the One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, that credit terminated for any expenditures made after December 31, 2025 — the IRS confirms no credit is available for property placed in service after that date.
If you installed solar before the deadline and haven’t filed yet, you can still claim it on your return. But for new installations in 2026, federal support is off the table — which makes
New Hampshire’s remaining state and local incentives, and the state’s punishing electricity rates, the whole financial case.
So Is There Still a New Hampshire Solar Rebate?
Here’s where honesty matters. New Hampshire’s Residential Small Renewable Generation Program — the one that paid $0.20 per watt, up to $1,000 — has had a rocky few years. Under Senate Bill 303 (2024), the statutory authority for the residential rebate was repealed, and per HB 2 (2025), all state rebate programs were closed to new projects until further notice, with the residential program described by the NH Department of Energy as permanently closed.
Some installer blogs still describe an active rebate with rolling applications and waitlists. The state’s own energy department says otherwise. The truth may be that new funding rounds get announced with little fanfare — which is exactly why your installer should be checking energy.nh.gov on your behalf before you sign anything, not quoting you a rebate that may not exist when your project completes.

What You Can Still Count On in New Hampshire (2026)
The rebate gets the headlines, but these four incentives quietly do most of the work:
- No state sales tax. New Hampshire charges zero sales tax on solar equipment — an immediate ~6–7% savings compared to neighboring Massachusetts, with no application required.
- Property tax exemption. RSA 72:62 lets towns exempt the value your solar system adds to your home. Many municipalities — including Londonderry — offer this exemption, but you typically must apply using Form PA-29; it is not automatic.
- Net metering. Your utility credits you for excess power your system sends to the grid, banking summer production against winter bills. New Hampshire utilities generally credit excess generation at a substantial portion of retail value.
- Battery incentives via ConnectedSolutions. If you add battery storage, Eversource’s ConnectedSolutions program has paid roughly $230 per kWh of storage — around $3,000 for a typical home battery — for allowing the utility to draw from your battery during peak demand. Funds are limited and administered first-come, first-served, so timing matters.
The Real 2026 Math for a New Hampshire Homeowner
Here’s the honest picture on a typical NH system: with all-in electricity rates around $0.29–$0.30 per kWh — roughly 48% above the national average — every kilowatt-hour your panels produce is worth nearly double what it would be in most of the country.
Eversource’s supply rate alone jumped to 14.009¢/kWh in August 2026, a 24% increase in a single adjustment.
Solar in 2026 isn’t about stacking tax credits anymore — it’s about locking in a fixed energy cost while utility rates keep climbing. Most NH homeowners still see payback in 8–12 years, followed by 15–20+ years of heavily reduced bills, with a 25-year manufacturer warranty on the equipment.
Frequently Asked Questions: NH Solar Incentives 2026
Is the New Hampshire solar rebate still available in 2026? The original Residential Small Renewable Generation Program was repealed and closed to new projects under SB 303 and HB 2 (2025), per the NH Department of Energy. Any successor program will be announced on energy.nh.gov — verify before counting on it.
Can I still get the 30% federal solar tax credit? No. The residential credit ended for expenditures after December 31, 2025, per the IRS. Only systems installed on or before that date (with unclaimed credits) still qualify.
Do solar panels increase my property taxes in NH? Not if your town participates. Londonderry and many other NH towns offer a property tax exemption for solar systems — but you usually must apply (Form PA-29).
Is there an incentive for solar batteries in New Hampshire? Yes — Eversource’s ConnectedSolutions program pays homeowners for grid-connected battery participation, historically around $230/kWh, subject to available funding.
What’s the single biggest reason to go solar in NH in 2026? Electricity rates. At ~$0.29–$0.30/kWh, New Hampshire’s power costs are among the highest in the country — and still rising.
Does Sunergy handle the paperwork? Yes — permits, interconnection, utility applications, and any active incentive filings are all part of your installation.
