New Hampshire Public Utilities Commission Renewable Energy Fund offers $0.20/W residential solar rebate, capped at $1,000 per system. Funded by the state Renewable Portfolio Standard alternative compliance payments.
New Hampshire Public Utilities Commission (NH PUC) administers the Residential Renewable Electrical Generation Rebate, funded by the Renewable Energy Fund (REF) which collects RPS alternative compliance payments from electricity suppliers. The rebate is structured as $0.20 per installed watt for residential solar PV (or other approved renewable technologies), capped at $1,000 per residential customer. Applications are filed online through the NH PUC sustainable energy portal post-installation; documentation includes proof of system commissioning, equipment specifications, and installer credentials. Programme funding renews annually based on REF collections; confirm current availability before assuming the full $1,000.
Eversource, Liberty, Unitil and NH Electric Cooperative offer net metering for residential systems up to 100 kW under PUC Order 26,029 with retail-rate energy crediting and time-varying rate experiments in some territories.
New Hampshire's net metering rules (currently under PUC Order 26,029 and successor orders) provide retail-rate compensation for residential exports up to 100 kW system capacity. The state's electricity rates are among the highest in the continental US (~$0.20-$0.23/kWh residential), making net metering economically attractive. Excess generation rolls forward as kWh credit; New Hampshire Electric Co-op operates a separate (typically less generous) programme. The PUC has periodically revisited net metering compensation; the framework remains intact through 2026 but utility-led reform efforts continue. Confirm current tariff with the relevant utility before contracting.
New Hampshire RSA 72:61-72 enables (but does not mandate) municipalities to exempt residential solar energy systems from local property tax. Approximately 80 of 234 NH municipalities have adopted the local-option exemption.
New Hampshire Revised Statutes Annotated (RSA) 72:61-72 enables municipalities to exempt residential renewable energy systems from local property tax assessment, but adoption is by individual municipality vote. Approximately 80 of 234 NH cities and towns have adopted the local-option exemption as of 2026 — including most major cities (Manchester, Nashua, Concord, Portsmouth) and many suburban towns. Homeowners must file Form A-9 with the local municipal assessor to claim the exemption where adopted. Confirm with your municipality before installation; the exemption can save $200-$500/year on a typical residential PV install over the system's life.
