The best NH solar company in 2026 holds a valid New Hampshire Master Electrician license, NABCEP certification, and has proven Net Metering 2.0 expertise for your utility (Eversource, Liberty, or Unitil). The federal 25D ITC is $0 as of 2026 and NH has no state income tax credit. Net metering credits, property tax exemption, NH Saves rebates, and zero sales tax are the primary financial drivers.
How to choose a NH solar company that holds the right licenses, understands Net Metering 2.0 for your utility, coordinates NH Saves rebates, and has real cold-climate installation experience.

Workmanship
New Hampshire's solar market is unique: no state income tax (so no state tax credit), three distinct utility territories with different net metering rules, and a climate that demands cold-weather expertise. The best NH solar companies navigate all of these factors and maximize your financial return through Net Metering 2.0, NH Saves coordination, and smart system design.
Issued by the NH Electricians' Board. Requires a Master Electrician license. Verify at the NH Office of Professional Licensure and Certification (OPLC) before signing anything.
NH's primary solar incentive. Credit structures differ by utility — Eversource, Liberty, and Unitil each handle credits differently. Your installer must design for your specific utility.
North American Board of Certified Energy Practitioners — the highest solar credential. In NH's smaller market, NABCEP certification is an even stronger signal of quality.
NH Saves offers insulation rebates, weatherization programs, and heat pump incentives. The best NH solar companies coordinate whole-home energy upgrades to maximize savings.
NH's snow loads, ice dams, and extreme cold require specialized design. Ask about snow load calculations, panel tilt angles for snow shedding, and seasonal production modeling.
Equipment warranties come from manufacturers. The workmanship warranty covers labor, wiring, and roof penetrations. 10 years minimum; 25 years is the gold standard.
Follow this 7-step process before signing any contract. Each step is designed around New Hampshire's specific legal requirements and incentive structure.
Verify the NH Electrical Contractor License
Every NH solar company must hold a valid New Hampshire Master Electrician license and Electrical Contractor registration. NH requires specific licensing through the NH Electricians' Board. Verify at the NH Office of Professional Licensure and Certification (OPLC) before signing any contract.
Confirm Net Metering 2.0 Expertise
New Hampshire's Net Metering 2.0 program allows residential systems up to 100 kW to receive credits for excess production. The credit rate and structure vary by utility (Eversource, Liberty, Unitil). Your installer must understand the specific net metering rules for your utility and design your system to maximize credits.
Check NABCEP Certification
Look for North American Board of Certified Energy Practitioners (NABCEP) credentials on the installation team, not just the company. Ask how many NABCEP-certified installers they have on staff and will work on your project.
Verify NH Saves Coordination Ability
NH Saves offers rebates for insulation, weatherization, and heat pump installations that stack with solar. The best NH solar companies coordinate with NH Saves for whole-home energy upgrades. Ask whether they handle NH Saves coordination or refer it out.
Review the Workmanship Warranty
Equipment warranties (panels 25 years, inverters 25 years) come from manufacturers. What matters is the installer's own workmanship warranty on labor, roof penetrations, and wiring. Minimum acceptable: 10 years. Gold standard: 25 years.
Compare Equipment Tiers & Financing Options
Understand what equipment tier is being proposed (budget, mid, or premium) and whether it matches your priorities. Get quotes for cash, solar loan, and lease/PPA side-by-side. The federal 25D ITC expired December 31, 2025 — NH has no state income tax, so there is no state solar tax credit either.
Check Cold-Climate and Regional Experience
New Hampshire's climate demands cold-weather expertise: snow load calculations, ice dam awareness, and system design for seasonal production variance. Ask about experience in your specific region — southern NH differs significantly from the Lakes Region or North Country.
Net Metering 2.0 credits, NH Saves rebates, cold-climate design — see exactly what you qualify for.
NH's incentive stack looks different from neighboring states. There is no state income tax credit and the federal ITC expired. But Net Metering 2.0, property tax exemption, zero sales tax, and NH Saves rebates still make solar financially compelling.
NH's Net Metering 2.0 allows residential systems up to 100 kW to receive credits for excess production. Eversource, Liberty, and Unitil each have different credit structures. Your installer must model your specific utility's rates to project accurate savings.
NH Saves is New Hampshire's statewide energy efficiency program, funded by all ratepayers. It offers rebates for insulation (75% off up to $4,000), heat pumps ($500-$1,500/unit), and home energy audits ($0 cost). Bundling with solar maximizes whole-home savings.
Under RSA 72:62, New Hampshire municipalities can vote to exempt solar energy systems from property taxation. Most NH towns have adopted this exemption. Your solar system adds home value without increasing property taxes.
New Hampshire has no sales tax period — which means no tax on solar equipment. This saves $1,200-$2,400 compared to neighboring states with 6-7% sales tax. It's an automatic advantage for NH homeowners.
Several NH municipalities have launched Community Power programs that aggregate buying power for lower electricity rates. In some Community Power towns, solar + net metering economics improve because the base rate structure changes. Ask your installer about Community Power in your town.
The best NH solar companies offer multiple equipment tiers and explain the trade-offs honestly. In NH, cold-climate performance ratings matter more than in warmer states.

NH's harsh winters make warranty coverage even more important. Ice dams, heavy snow loads, and freeze-thaw cycles test installations harder than milder climates.
Covers manufacturing defects. Comes from the panel manufacturer, not your installer. Verify the manufacturer has a US warranty service office — foreign-only companies are harder to claim against.
Guarantees minimum power output over time. In NH's climate, panels with better temperature coefficients (lower power loss in heat) and strong low-light performance matter more.
Microinverters (Enphase IQ8) and optimizers (SolarEdge) carry 25-year warranties. String inverters may only carry 10-12 years. Match inverter warranty to panel warranty.
Covers labor, wiring, roof penetrations, and installation quality. In NH, this warranty is critical — roof leaks from freeze-thaw cycles, snow load damage, and ice dam issues all fall under workmanship. Demand 25 years.
New Hampshire's Consumer Protection Bureau (RSA 358-A) handles solar contractor complaints. These are the most common warning signs to watch for.
Claims you still get the federal tax credit
Section 25D expired December 31, 2025. $0 for homeowners in 2026. NH also has no state income tax, so there is no state tax credit either. Any company claiming federal or state tax credits is misleading you.
No NH Master Electrician license or Electrical Contractor registration
These are legal requirements in New Hampshire. Working with an unlicensed contractor voids your consumer protections and may invalidate your homeowner's insurance for installation-related damage.
Cannot explain Net Metering 2.0 rules for your utility
Net metering is NH's primary solar incentive. Eversource, Liberty, and Unitil each have different credit structures. If your installer can't explain how your specific utility handles net metering credits, your system design may not be optimized.
Workmanship warranty under 10 years
Short warranties suggest the company doesn't expect to be around long enough to honor them. NH's Consumer Protection Bureau receives complaints about contractors that disappear after installation.
No cold-climate installation experience
NH sees significant snow loads, ice dams, and extreme cold. Installers without cold-climate experience may under-design structural supports, use inappropriate hardware, or fail to account for seasonal production variance.
Inflated production estimates
Verify production estimates against NREL PVWatts (free online tool). NH's northern latitude, snow cover, and tree shading make accurate modeling essential. Companies that inflate estimates will under-deliver.
Door-to-door high-pressure sales tactics
Legitimate NH solar companies don't need to pressure you into a same-day decision. NH consumer protection law (RSA 358-A) provides recourse, but avoiding predatory companies is always better.

NH Solar Without the ITC (2026)
Full financial analysis with NEM 2.0 and state incentives only
A legitimate NH solar company must hold: (1) a New Hampshire Master Electrician license, (2) Electrical Contractor registration through the NH Electricians' Board, (3) proper liability insurance and workers' compensation coverage, and (4) any municipality-specific permits or registrations. Verify license status at the NH Office of Professional Licensure and Certification (OPLC).
No. The Section 25D residential solar ITC expired December 31, 2025 and is $0 for homeowners in 2026. Additionally, New Hampshire has no state income tax, so there is no state-level solar tax credit either. However, companies offering lease or PPA financing may still pass through Section 48/48E commercial ITC savings. NH's Net Metering 2.0, property tax exemption, and NH Saves rebates are the primary remaining incentives.
Very important. Net Metering 2.0 is NH's primary solar incentive, allowing residential systems up to 100 kW to receive credits for excess production. Credit rates vary by utility — Eversource, Liberty, and Unitil each have different structures. A knowledgeable installer designs your system to maximize net metering income based on your specific utility's rate structure and your consumption patterns.
Key red flags: (1) Claiming you can still get the federal ITC — 25D expired December 31, 2025. (2) No NH Master Electrician license or Electrical Contractor registration. (3) Workmanship warranty less than 10 years. (4) No NABCEP-certified installers on staff. (5) Cannot explain Net Metering 2.0 rules for your utility. (6) Door-to-door sales pressure. (7) Inflated production estimates (verify with NREL PVWatts). (8) No cold-climate installation experience.
Yes. NuWatt Energy holds all required New Hampshire licenses including Master Electrician and Electrical Contractor registration. Our teams include NABCEP-certified installers with extensive cold-climate experience across Eversource, Liberty, and Unitil territories. We coordinate NH Saves rebates and offer cash, loan, and third-party financing options with 25-year workmanship warranties.
No. New Hampshire has no state income tax, which means there is no state-level solar tax credit. However, NH does exempt solar energy systems from property tax increases (RSA 72:62) and the state has no sales tax at all. Combined with Net Metering 2.0 credits and NH Saves rebates, solar is still financially compelling — but the math differs from neighboring states like Massachusetts.
Top NH solar companies should offer at minimum: mid-tier equipment (Silfab, Q.CELLS, or equivalent panels; Enphase IQ8 microinverters or equivalent); a premium tier option (REC, Maxeon, or equivalent); and battery options for backup power (Enphase IQ10C, Franklin, Tesla Powerwall). NH's winter storms and rural areas make battery backup particularly valuable. Cold-climate rated panels with strong snow load ratings are essential.
