Are solar panels worth it in New Hampshire? The honest 2026 answer
For most NH homeowners who own their home: yes — but the payback is longer than southern states and there is no state income credit. Here is the complete, honest picture so you can decide for yourself.
New Hampshire is a legitimate solar market with a clean, functional incentive structure — but it requires realistic expectations. There is no state income tax credit. The federal credit expired at the end of 2025. What NH has: Eversource New Hampshire full retail-rate net metering, no general sales tax on anything (including solar equipment), and a property tax exemption on solar-added home value. For homeowners with a well-oriented roof and a long-term horizon, the math works.
The core case for NH solar
Eversource NH charges approximately $0.22 to $0.26/kWh, which is competitive with the New England average. An 8 kW system in New Hampshire producing 11,000 kWh/year offsets approximately $2,640/year in electricity costs. At a net system cost of $24,000 (no sales tax means no exemption needed, just the base price), payback falls around 9 years. Over 25 years, net savings approach $42,000 at today's rates. NH electricity rates have risen historically, adding to the long-term value of a fixed-cost solar investment.
New Hampshire also has no general sales tax. This saves the 6.25% that Massachusetts homeowners celebrate as a solar exemption — in NH it is simply the baseline. On a $24,000 system, that is roughly $1,500 more in your pocket than a MA buyer in a non-exempt state. It is a quiet but real advantage.
Resilience: NH winter storms
New Hampshire's nor'easters and ice storms produce real multi-day grid outages, particularly in rural communities. Battery storage adds resilience value for NH homeowners similar to Vermont. The federal standalone battery storage tax credit (30% under the IRA) may apply to 2026 battery installations; verify current IRS guidance. For rural NH homeowners who experience regular winter outages, the combination of solar plus battery provides both financial return and practical storm resilience.
When NH solar does NOT make sense
Solar is likely not right for your NH home if you rent, plan to sell within 4 to 5 years (payback is 7 to 11 years, so you would not recoup the investment), have a roof heavily shaded by trees or neighboring structures, have a roof near end of life (replace first), or have very low electricity usage where savings would be minimal. We will give you an honest answer for your specific situation rather than pushing you forward if these apply.
