New Hampshire Solar Incentives, Rebates and Grants (2026)

Federal Tax Credit Update

The 30% federal residential clean energy credit (Section 25D) ended for systems placed in service after December 31, 2025. Homeowners who buy solar in 2026 can no longer claim it on their own taxes. Some third-party ownership programs (like a Propel lease) can still use commercial credits and pass part of that value to you as a discount.

State Programs

  • State residential solar rebate: closed. New Hampshire permanently ended its residential solar rebate (SB 303, 2024), and all state renewable rebate programs are closed to new projects under HB 2 (2025). https://www.energy.nh.gov/renewable-energy/renewable-energy-rebates
  • Net metering: your utility credits extra power your system sends to the grid. https://www.puc.nh.gov
  • Local property tax exemption: towns may choose to adopt a solar exemption (RSA 72:62); many have, often for 100% of the equipment value. It is not automatic, so check with your town assessor (applications are usually due April 15). https://gc.nh.gov/rsa/html/v/72/72-62.htm
  • No state sales tax: New Hampshire has no general sales tax, so you pay none on solar equipment.

Utility Programs

  • Battery programs: some utilities (such as Eversource and Liberty) offer payments or programs for home batteries. Check with your utility.
  • NHSaves: home energy assessments and efficiency rebates. https://www.nhsaves.com
