Find out how much you can save based on your location and current energy usage.
New Hampshire residential electricity costs roughly 23.5–27¢/kWh — around 20–25% above the national average. Every kilowatt-hour your panels produce offsets expensive utility power, shortening payback periods compared to low-rate states even with modest sun exposure.
New Hampshire has no state sales tax at all. Solar panels, inverters, racking, and installation labor are inherently untaxed at the state level — not because of a targeted solar exemption, but because the tax simply doesn't exist here.
New Hampshire has no tax on wages, salaries, or (since January 1, 2025, when the Interest & Dividends tax was fully repealed) on any investment income either. This is a structural feature of the state — not a temporary solar credit — meaning any cash savings from your solar system stay entirely yours at the state level.
