What New Hampshire still offers after the federal credit ended
Every incentive on this page is verified against New Hampshire government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Franklin systems completed in 2026 get $0 from it.
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 Franklin homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Franklin tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: New Hampshire's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
The 2026 numbers

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Residential Renewable Electrical Generation Rebate Program is permanently closed - RSA 362-F:10 V-VII and IX were repealed by SB 303 (2024), and HB 2 (2025) closed all remaining Renewable Energy Fund rebate programs to new projects - so there is no state cash incentive for a 2026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.

What this means for Franklin roofs
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Getting Franklin quotes
Same-day contracts are a red flag in this industry. Legitimate NH installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
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.
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 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 is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
