Overview
Is Solar Worth It in New Hampshire?
New Hampshire has a unique advantage for solar: no state income tax. This means New Hampshire's lack of state income tax simplified the old federal ITC calculation -- though the federal 30% ITC expired Dec 31, 2025, the state's strong net metering and property tax exemption remain fully intact. Combined with high electricity rates (averaging $0.22+/kWh), strong net metering laws, and a property tax exemption, New Hampshire homeowners have solid financial reasons to go solar.
The Granite State may not be the sunniest, but its high electricity costs mean every kilowatt-hour your panels produce delivers real savings. New Hampshire's net metering policy is among the strongest in New England, and the state has been expanding its solar capacity rapidly.
