The federal residential solar tax credit is gone. The state rebate was repealed. The installer you choose in 2026 matters more than ever. We compared pricing, NEM 2.0 expertise, property tax guidance, and warranty coverage from five companies actively installing in New Hampshire.
The best solar companies in New Hampshire in 2026 are NuWatt Energy (best local installer), Sunrun (best for lease/PPA), and ReVision Energy (best B Corp option). With the federal residential ITC expired and the NH state rebate repealed (SB 303), choosing an installer who understands NEM 2.0 credit optimization (~85% of retail) and RSA 72:62 property tax exemptions is critical for maximizing your savings.
We evaluated each installer on eight criteria that matter most for New Hampshire homeowners in the post-ITC landscape. Companies that understand NH-specific programs and credit structures ranked higher because those factors now drive the bulk of your financial return.

The solar landscape in New Hampshire shifted dramatically when the One Big Beautiful Bill Act let the Section 25D residential tax credit expire on December 31, 2025. Combined with the state rebate repeal, here is what that means for your installer decision.
The 30% federal tax credit for homeowner-owned solar (Section 25D) expired. There is no longer a $7,000–$10,000 credit to offset your upfront cost on cash or loan purchases. This makes every other savings lever — NEM 2.0 credits, property tax exemption, utility rate arbitrage — more important than ever.
NH net metering credits are worth ~85% of retail (not 1:1). On a $0.27/kWh average rate, that is approximately $0.23/kWh in credit value. An installer who models 1:1 credits will overestimate your savings by 15%, leading to disappointment. NEM 2.0 terms are locked through 2041, giving accurate projections long-term certainty.
SB 303 (2024) repealed the NH state solar rebate. There is no state-level financial incentive for residential solar. Your savings now depend entirely on NEM 2.0 credits, the RSA 72:62 property tax exemption (available in ~66% of towns, saving ~$584/yr), and high electricity rates. Any installer referencing a state rebate is outdated.
Under a lease or PPA, the third-party system owner (not the homeowner, not the installer) claims the Section 48/48E commercial ITC. This means $0-down options like NuWatt's Propel program now offer some of the best economics for homeowners who cannot claim the credit themselves.
Bottom Line
In 2025, you could choose almost any installer and still save money thanks to the 30% tax credit. In 2026, with no federal ITC and no state rebate, your installer's knowledge of NEM 2.0 credit structure and RSA 72:62 property tax exemptions directly determines whether your system pays for itself in 9 years or 14.
Protect yourself from bad deals. If you encounter any of these warning signs during the sales process, proceed with caution.
The residential solar tax credit (Section 25D) expired on December 31, 2025. Any installer still quoting 30% off is either uninformed or dishonest. The only way to access the ITC now is through a lease/PPA where the third-party owner claims Section 48/48E.
Dealer fees (also called origination fees) of 15–30% are baked into many solar loans. If an installer won't break out the dealer fee separately, you cannot accurately compare their loan price to a cash price or another company’s quote.
NH net metering provides credits worth approximately 85% of retail (100% supply + 100% transmission + 25% distribution). An installer who claims full 1:1 retail credits is either misinformed or overstating your savings projections. Accurate NEM modeling is essential for realistic payback estimates.
The New Hampshire state solar rebate was repealed by SB 303 in 2024. Any installer referencing a current state rebate is working with outdated information. Your savings come from NEM 2.0 credits, property tax exemption, and high electricity rates — not a state rebate.
Legitimate solar companies encourage you to get multiple quotes. A company that pressures you to sign immediately — especially by claiming a "limited-time discount" — is using a high-pressure sales tactic. New Hampshire law gives you 3 business days to cancel most home improvement contracts.
Accurate system design requires detailed roof analysis — orientation, pitch, shading, rafter spacing, and electrical panel capacity. A quote based solely on your electric bill is likely inaccurate and could lead to costly change orders.
City-specific guides with local pricing, utility rates, and installer recommendations.
NuWatt Energy ranks as the best solar company in New Hampshire for 2026 based on local crew quality, NEM 2.0 optimization expertise, RSA 72:62 property tax guidance, and competitive pricing ($3.10–$3.30/W). ReVision Energy is a strong runner-up for homeowners who prioritize a B Corp installer with deep New England roots. Sunrun is the best option for homeowners who want a $0-down lease or PPA backed by a national brand.
Yes, solar can still be a sound investment in NH despite the Section 25D residential tax credit expiring on December 31, 2025. With average electricity rates at $0.27/kWh and rising, NEM 2.0 credits worth ~85% of retail locked through 2041, and RSA 72:62 property tax exemptions in ~66% of towns, typical payback is 9–12 years for cash purchases. Lease/PPA options let the third-party owner claim the Section 48/48E commercial ITC, passing savings to you through lower monthly payments.
NH uses NEM 2.0, which provides credits worth 100% of supply charges + 100% of transmission charges + 25% of distribution charges. This totals approximately 85% of your full retail rate. Credits are applied monthly with annual true-up. NEM 2.0 terms are locked through 2041, giving solar owners long-term rate certainty. This is NOT full 1:1 retail net metering — any installer who claims otherwise is misinformed.
No. The NH state solar rebate was repealed by SB 303 in 2024. There is no state-level financial incentive for residential solar in New Hampshire. Your primary savings come from NEM 2.0 credits (~85% retail), the RSA 72:62 property tax exemption (available in ~66% of towns, saving ~$584/year), and high electricity rates ($0.27/kWh average). Any installer claiming a NH state rebate is either outdated or dishonest.
The average cost of solar panels in New Hampshire is $3.03/W before any incentives. For a typical 8 kW system, that is approximately $24,240. With no federal residential tax credit (Section 25D expired) and no state rebate (SB 303 repealed), your upfront cost equals the full system price for cash purchases. Lease/PPA options through programs like NuWatt’s Propel can reduce or eliminate upfront costs, with the third-party owner claiming the Section 48/48E commercial ITC.
Unitil ($0.26/kWh) offers the highest rate, meaning the greatest NEM 2.0 credit value per kWh exported. Eversource ($0.32/kWh, ~71% of NH customers) is the most common and provides solid credit values. Liberty ($0.24/kWh) and NH Electric Cooperative ($0.22/kWh) have lower rates and longer payback periods. Over 40% of NH customers are on Community Power (CPCNH) aggregation, which can offer competitive supply rates — your installer should help you compare.
Key questions for NH solar installers: (1) Do you understand NEM 2.0 is ~85% retail, not 1:1? (2) Will you help me verify RSA 72:62 property tax exemption in my town? (3) Do you use your own crews or subcontractors? (4) What is the dealer fee on this loan? (5) How do you handle Community Power (CPCNH) customers? (6) What panel and inverter brands do you offer? (7) What is your workmanship warranty? (8) How long from contract to permission to operate? (9) Can I see local references in my area?
With the residential tax credit expired, leasing and PPAs have become more competitive in NH. Under a lease/PPA, the third-party system owner claims the Section 48/48E commercial ITC and passes savings to you through lower payments. Cash purchases still offer the highest total savings over 25 years but require $20,000–$28,000 upfront with no tax credit offset. Loans remain an option but watch for dealer fees of 15–30%. The best choice depends on your budget, how long you plan to stay in your home, and your risk tolerance.
