The federal 25D tax credit is gone. The NH state rebate was repealed by SB 303. Most installers haven't updated their quotes. NuWatt gives you real 2026 numbers — no phantom incentives, no bait-and-switch.
New Hampshire homeowners face a double hit in 2026: the federal residential ITC expired and the state solar rebate was repealed. The installer you choose determines whether you overpay or find the last remaining path to federal savings.
Section 25D — the 30% residential solar tax credit — expired December 31, 2025. If you buy a system with cash or a loan in 2026, your federal credit is $0.
New Hampshire's state solar rebate was also repealed by SB 303 in 2024. There is no state rebate to offset costs.
Any installer quoting you a 30% federal credit or a state rebate for a purchased system is using outdated numbers.
Section 48/48E — the commercial ITC — is still active for projects beginning construction before July 4, 2026. A third-party system owner (not you) claims the credit.
Through a solar lease or PPA, the financing company claims the 30% ITC and passes the savings to you as a lower monthly payment. This is the only federal incentive path left for NH homeowners.
We offer both paths: honest cash/loan pricing at $0 federal credit and $0 state rebate, and our Propel lease program that accesses Section 48 savings on your behalf.
You choose. We don't pressure. Every quote reflects real 2026 numbers — no phantom incentives, no surprises at signing.
In 2024, New Hampshire passed SB 303, which repealed the state's solar rebate program. Before this, homeowners could receive a rebate of up to $1,000 from the PUC. That incentive no longer exists.
Some installers and online estimate tools have not updated their calculations. If a quote shows a "NH state rebate" or "PUC incentive," that number is wrong. NuWatt builds every NH quote on reality: $0 state rebate and $0 federal residential ITC.
Despite these losses, solar still makes financial sense in New Hampshire because of high electricity rates ($0.27/kWh average), strong NEM 2.0 net metering locked through 2041, property tax exemptions in most towns, and zero state sales tax. The payback period has increased to approximately 9.5 years, but the 25-year savings remain substantial.
We're not a marketplace. We're not a national chain with subcontracted crews. We're a New England solar company that has been serving the region since 2008 — and we know New Hampshire inside and out.
Founded in 2008. We survived the financial crisis, panel shortages, policy changes, and the ITC expiration. We'll be here for your warranty.
The gold standard in solar certification. Only ~10% of solar installers in the US hold this credential.
One of the few NH-area installers certified to install Tesla Powerwall 3. We also install Enphase IQ and Franklin aPower batteries.
We handle net metering enrollment, interconnection applications, and RSA 72:62 property tax exemption guidance — all included in our service.
Our installation teams are NuWatt employees, not day-labor subcontractors. Same quality, accountability, and safety standards on every job.
Published $/W rates. We never pad quotes with expired incentives. What we quote is what you pay — $0 federal ITC, $0 state rebate, honest numbers.
Many installers and online calculators assume 1:1 net metering in New Hampshire. That is wrong. Understanding the real credit structure is essential for accurate payback calculations.
Full credit for energy supply
Full credit for transmission
Only 25% credit for distribution
At NH's $0.27/kWh average rate, exported solar earns approximately $0.23/kWh in NEM 2.0 credits.
An installer using 1:1 net metering in their model will overestimate your savings by approximately 15% and understate your payback period by 1-2 years. NuWatt uses the actual NEM 2.0 credit structure in every proposal.
The good news: NEM 2.0 rates are locked through 2041 under current law. Your savings are predictable for at least the next 15 years — longer than most system payback periods.
NuWatt also analyzes whether Community Power Coalition of NH (CPCNH) rates in your town may further affect your solar economics, since 40%+ of NH customers now participate in competitive supply programs.

Three ways to go solar in New Hampshire. Here's how they compare on the factors that matter most in 2026.
| Factor | NuWatt (Direct) | Marketplace (e.g. EnergySage) | National Chain (e.g. Sunrun) |
|---|---|---|---|
| Post-ITC Honesty | Transparent: $0 federal credit for cash/loan purchases in 2026 | Many listings still show outdated 30% ITC in estimates | Sales reps may reference expired credits to close deals |
| Section 48 Lease/PPA | Propel lease passes Section 48 savings to homeowner | Varies by installer — no guarantee of 48 access | PPAs available but lock-in terms may be unfavorable |
| NH Program Expertise | NEM 2.0 enrollment, RSA 72:62 guidance, CPCNH rate analysis | Installer may or may not understand NH net metering rules | Often skip NH-specific program enrollment |
| SB 303 Awareness | Honest: state rebate repealed in 2024 — no fake incentive padding | Some listings may still reference the repealed $1K rebate | National reps rarely track state-level policy changes |
| Equipment Quality | Hyundai/Silfab/REC panels, Enphase microinverters | Equipment varies widely by installer | Proprietary or limited equipment choices |
| Pricing Transparency | Published $/W pricing, no hidden fees | Must request quotes from 3-5 installers to compare | Opaque pricing, high-pressure sales tactics |
| Local Presence | New England-based team, responsive local service | Connects to local installers (quality varies) | Subcontracted crews, limited local accountability |
| Warranty Support | 25-year panel + 25-year Enphase + 10-year workmanship | Depends on the installer you choose | Good panel warranty, but service via call centers |
The federal credit and state rebate are both gone. But New Hampshire still has meaningful incentives that make solar work financially. NuWatt enrolls you in every program you qualify for.
Export excess solar and earn credits for supply, transmission, and 25% of distribution charges. Locked through 2041. At $0.27/kWh average, that's ~$0.23/kWh in credits.

Yes. NuWatt Energy is fully licensed, bonded, and insured to perform solar installations in New Hampshire. We are NABCEP-certified, Tesla Powerwall Certified, A+ BBB rated, and have completed over 350 residential and commercial solar installations across the state.
No. The Section 25D residential solar tax credit expired on December 31, 2025. Cash and loan purchases receive $0 in federal credits. The only way to access federal incentives in 2026 is through a Section 48 lease or PPA, where a third-party system owner claims the commercial ITC and passes savings to you as a lower monthly payment. NuWatt offers this through our Propel lease program.
No. New Hampshire's state solar rebate was repealed by SB 303 in 2024. There is no state rebate for residential solar. Any installer still referencing a state rebate in their quotes is using outdated information. NuWatt provides honest 2026 pricing without inflating estimates with incentives that no longer exist.
New Hampshire still offers NEM 2.0 net metering (credits at approximately 85% of retail rate, locked through 2041), a local-option property tax exemption under RSA 72:62 (available in about 66% of NH towns, saving roughly $584/year), and no state sales tax on anything including solar equipment. The Propel lease also lets you access Section 48 commercial ITC savings through a third-party system owner.
Without the federal ITC or state rebate, New Hampshire solar costs approximately $3.03 per watt installed in 2026. A typical 8 kW system costs around $24,240 before any remaining incentives. With NEM 2.0 credits and property tax savings, payback is approximately 9.5 years. With a Section 48 Propel lease, monthly payments start lower than your current electric bill.
NH uses NEM 2.0, which is NOT 1:1. You receive credits for 100% of supply charges plus 100% of transmission charges, but only 25% of distribution charges — working out to approximately 85% of the full retail rate. These rates are locked through 2041 under current law. NuWatt handles all interconnection and net metering enrollment paperwork.
NuWatt serves all of New Hampshire including Southern NH (Nashua, Salem, Derry), the Seacoast (Portsmouth, Dover, Exeter), Manchester Metro, Concord and the Lakes Region, and the Upper Valley (Lebanon, Hanover). We install in Eversource, Liberty, Unitil, and NHEC territories.
From signed contract to power-on, most residential installations take 8-12 weeks. This includes engineering (1-2 weeks), permitting (2-4 weeks), installation (1-2 days), electrical inspection, and utility interconnection (2-4 weeks). NuWatt handles all permitting and utility paperwork.
Yes. We are Tesla Powerwall Certified Installers and also install Enphase IQ batteries and Franklin aPower systems. While NH does not currently have a ConnectedSolutions-style battery incentive program like Massachusetts, batteries provide backup power during outages and help you store excess solar for evening use, maximizing your self-consumption and NEM 2.0 value.
Both NuWatt and ReVision Energy are established New England solar installers. NuWatt differentiates with transparent published $/W pricing, honest post-ITC quotes that reflect 2026 reality (no expired 25D credit in estimates), Propel lease access for Section 48 savings, and three panel tier options. We encourage you to get quotes from both — just make sure any quote you compare uses $0 for the federal residential ITC.
Get an honest 2026 quote from a local installer — no expired tax credits, no repealed rebates, no high-pressure sales. Just real numbers and the best path for your home.
