Residential Solar Water Heating Rebates

February 22, 2023


New Hampshire offers rebates for residential solar water-heating systems. The rebate is equal to $1,500 for systems with an annual estimated output of 5.5 MMBTU to 19.9 MMBTU; $1,700 for systems with an annual estimated output of 20 MMBTU to 29.9 MMBTU; and $1,900 for systems with an annual estimated output of 30 MMBTU or more. Rebates will be awarded for eligible projects as long as program funding is available.

The application process consists of two steps. The first step is required for pre-approval and to reserve a rebate, and the second step is the final application for the rebate payment. Systems must be installed by a qualified installer authorized to do business in New Hampshire. Self-installations are allowed, but such installers are encouraged to work with the Plymouth Area Renewable Energy Initiative. See the program website for more information.

This program is funded by alternative compliance payments from New Hampshire's renewable portfolio standard (RPS), which are directed into the state's renewable energy fund.
