These incentives change frequently, so research current programs thoroughly and consider acting promptly to maximize your solar investment benefits.

Incentive Type Description Source
Residential Clean Energy Credit Federal tax credit A federal tax credit worth 30% the cost of a solar panel system in the year it’s installed Learn More
Property Tax Exemption State tax exemption New Hampshire’s General Court has given authority to each city and town to exempt solar’s incremental value from property taxes Learn More

The Residential Clean Energy Credit lets people claim a tax credit worth 30% the cost of a solar panel system in the year it’s installed. The credit can only be used against taxes you owe or have already paid that year, but any excess credit can be rolled over to future years.

The credit is broadly available, though there are a few restrictions — you must own the panels and they must be on a house you live in — so be sure to consult a tax professional about your situation.

New Hampshire’s Property Tax Exemption for Solar Energy Systems allows cities and towns to exempt the added value of solar installations from property tax assessments. This means that while your solar system may increase your home’s overall value, you won’t pay additional property taxes on that increased value. The exemption applies to the assessed value of the solar energy system itself, not your entire property.

The financial benefit varies by location since each city and town must individually choose to adopt this exemption under state law. If your municipality has adopted the exemption, you could save hundreds of dollars annually in property taxes depending on your system’s value and local tax rates. To be eligible, you must own real property equipped with a solar energy system as defined by New Hampshire law. There are no specific deadlines mentioned in the statute, but you should check with your local tax assessor about application procedures and timing requirements, as these may vary by municipality.

Net metering in New Hampshire allows solar homeowners to receive credit for excess electricity their solar panels send back to the grid. When your solar system produces more power than your home uses, that extra electricity flows to the grid and reduces your electric bill. The specific benefits depend on which utility company serves your area, with rates and terms varying between Eversource Energy, Unitil Energy Services, Liberty Utilities, and NH Electric Cooperative.

For most NH utilities (Eversource, Unitil, and Liberty), you receive nearly full retail credit for excess solar production, with only small non-bypassable charges of 0.5 to 2 cents per kWh deducted. When you produce more than you use in a month, you earn bill credits ranging from about 13 to 21 cents per kWh depending on your utility. NH Electric Cooperative operates differently, offering export credits at about 25% of the retail rate (around 14.76 cents per kWh in 2023). All utilities allow credits to roll over year to year, and you can request payment for accumulated credits over $100 after your March billing cycle. Keep in mind that customers who choose competitive retail energy suppliers may not be eligible for the full credit amount, as they won’t receive the Default Energy Service portion of the credit.

Leasing Solar Panels
