Quick Answer: Solar Permits & Incentives in New Hampshire
New Hampshire requires a local municipal building permit for solar installations. There is no statewide solar permit, so requirements differ by town. The NH Department of Energy manages several grant and rebate programs funded by the state's Renewable Portfolio Standard (RPS). Additionally, the NH Community Development Finance Authority (CDFA) offers a revolving loan fund for businesses and nonprofits.
The RPS (NH RSA 362-F) is the main policy behind these initiatives. It mandates that electricity providers source 25.2% of their retail electricity from renewables by 2025. Utility compliance payments for RPS shortfalls fund the Renewable Energy Fund, which supports most state solar incentive programs.
Key programs include:
| Program | Who It Serves | Type |
|---|---|---|
| C&I Solar Rebate Program | Businesses, nonprofits, municipalities | Rebate |
| C&I Renewable Energy Grants | Commercial, industrial, public, multifamily | Grant |
| Low-Moderate Income Solar Grant | LMI community solar, manufactured housing | Grant |
| Clean Energy Fund | Businesses, nonprofits, municipalities | Loan |
