How this incentive fits New Hampshire's solar picture

The NH RGGI Solar Incentive pays out as a direct rebate rather than a tax credit, one of New Hampshire's solar incentive programs tracked in DSIRE. Eligibility is scoped to residential customers, with a stated benefit of Up to $0.15/W. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That's the backdrop this incentive works against. New Hampshire averages 4.2 kWh/m²/day of usable sunlight and residential rates of 25.5¢/kWh, producing an estimated 7,358 kWh/year and $1,876 of annual utility offset on a typical 6 kW system costing $18,300. That baseline already implies a 9.8-year simple payback and a 25-year modeled net of roughly $28,600 before this incentive - every dollar this rebate delivers compresses that payback further.

A handful of other levers are worth checking alongside this one. New Hampshire has 3 solar incentive programs indexed in DSIRE, including adjacent options like NH Net Metering. The state's net-metering policy is classified as full, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
