What New Hampshire pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is New Hampshire's current rule in plain words, with the official source.
Under New Hampshire's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Rochester homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Rochester, New Hampshire has about 33,598 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
Whether solar still pays in New Hampshire after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.
The honest 2026 answer for Rochester: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is New Hampshire's export compensation, covered in the net metering section.

New Hampshire rules that decide your payback
| Rule | New Hampshire status |
|---|---|
| Export compensation (net metering) | Residential systems of 100 kW or less net meter under the 'alternative' NEM 2.0 tariff in effect since September 1, 2017, which credits exported generation at the full default-service (energy) rate and the full transmission rate but only 25% of the distribution rate, gives no credit at all for system benefits, stranded cost or storm recovery charges, and converts leftover net kWh into a monetary bill credit carried forward. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Exempt |
| Property tax on added home value | No exclusion on record |
New Hampshire's Residential Renewable Electrical Generation Rebate Program is permanently closed - RSA 362-F:10 V-VII and IX were repealed by SB 303 (2024), and HB 2 (2025) closed all remaining Renewable Energy Fund rebate programs to new projects - so there is no state cash incentive for a 2026 homeowner install, and net metering is additionally rationed by a 100 MW statewide capacity cap allocated among utility territories.

Common questions
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
