Installers, contractors and solar service companies whose service area covers New Hampshire.
New Hampshire solar is small, local, and almost entirely on rooftops: of the roughly 377 megawatts installed in the state, nearly all of it is small-scale — panels on homes, farms, schools, and businesses rather than distant solar farms. The state's first utility-owned solar farm, Unitil's 4.9-megawatt array in Kingston, only arrived in 2025, and towns across the state are now banding together through community power programs to buy solar at a larger scale.
What makes rooftop solar pencil out here is net metering. Every New Hampshire utility must offer it for systems up to a full megawatt, and for home-sized systems the power you export earns credits worth 100% of the energy and transmission charges plus 25% of the distribution charge. Unused kilowatt-hour credits roll forward indefinitely — July's surplus can still be offsetting your January heating-season bills — and you keep ownership of your system's renewable energy credits. With some of the highest electricity prices in the country, every kilowatt-hour you use yourself is worth a lot.
New Hampshire has no state income or sales tax, so the savings stack is simple: self-consumption, net metering credits, and a local property tax exemption many towns have adopted for the value solar adds to a home.
