New Hampshire Solar Panel Installation Incentives & Rebates | 2025

For rural small businesses and agricultural properties, the REAP Grant could provide funding that covers between 80% and 100% of the necessary expenses for installing renewable energy systems. Think you might qualify? Use our REAP Grant eligibility tool to confirm your eligibility.

The federal government offers a 30% tax credit for residential solar systems, making solar attractive and practical for a variety of homeowners. Moreover, several state and local programs are in place to further encourage the adoption of solar energy.

In New Hampshire, 9 solar rebates and incentives are currently available from various utilities and government organizations.

Residential Small Renewable Energy Rebate Program

Value:Up to $1

The New Hampshire Public Utilities Commission manages a centralized incentive program for homeowners installing new renewable energy systems. Rebates are funded through penalty fees paid by utilities as part of the state's renewable portfolio standard law. Qualifying projects include solar PV and wind microturbines. Solar systems should be UL certified, while wind systems are subject to minimum speed, setback, and height requirements. The total rebate amount will vary depending on a system's capacity. Currently, the incentive rate is 20 cents per watt up to a maximum of $1,000 or 30% of the original purchase price. Additional information is available from the PUC website.

Commercial & Industrial Solar Rebate Program

Value:Up to $10,000

The New Hampshire Public Utilities Commission manages a centralized incentive program for homeowners installing new solar water heaters and HVAC systems. Rebates are funded through penalty fees paid by utilities as part of renewable portfolio standard laws. Qualifying projects should meet all applicable local, state, and federal standards, with the project owner requesting funding and obtaining an energy efficiency audit prior to installation. Homeowners served by a local public utility do not qualify as they are not subject to the renewable portfolio standard. Additional information is available through the PUC website.

Residential Solar Water Heating Rebates

Value:Up to $1,900

Any New Hampshire homeowner may qualify for a rebate on new solar water heaters regardless of which utility they use. Incentives are offered through the state Public Utilities Commission and are funded through penalty fees assessed to utilities as part of the state's renewable portfolio standard. Rebate amounts are fixed and depend on the BTU capacity of the heater, ranging from $1,500 to $1,900. Homeowners must apply and earn preapproval before purchasing and installing their system through a participating contractor. Additional information is available through the PUC website.

Residential Solar Water Heating Rebates

Value:Up to $1,500

Any New Hampshire homeowner may qualify for a rebate on new solar water heaters regardless of which utility they use. Incentives are offered through the state Public Utilities Commission and are funded through penalty fees assessed to utilities as part of the state's renewable portfolio standard. Rebate amounts are fixed and depend on the BTU capacity of the heater, ranging from $1,500 to $1,900. Homeowners must apply and earn preapproval before purchasing and installing their system through a participating contractor. Additional information is available through the PUC website.

Local Option - Energy Efficiency & Clean Energy Districts

Value:Varies

Local and county governments in New Hampshire may create property-assessed clean energy (PACE) financing programs to support property owners making renewable energy investments or energy efficiency improvements. Effectively, PACE funding comes from the government, with applications and screening handled through a private lender. Repayment will take the form of a property tax lien senior to mortgages. Should the owner sell or transfer their property, the new owner will be responsible for the loan. Any commercial, industrial, or large multi-family residential property may qualify for PACE loans. Single-family homes or multi-family properties below 5 units do not qualify due to regulatory concerns from the FHFA. Potential applicants should check with their local government to determine financing options and requirements for participation.

Renewable Portfolio Standard

Value:Varies

In New Hampshire, all private utilities and electrical cooperatives are required to comply with a renewable portfolio standard dictating the state's investment in clean energy. Current objectives require at least 25.2% of retail electricity in the state to be sourced renewably by 2025. Eligible technologies include solar, wind, biomass, hydroelectric, and some landfill gas systems. Compliance with the standard is measured using a Renewable Energy Credit (REC) system pegging a fixed amount of electricity to a variable dollar value. Each renewable energy device generates RECs, though utilities are expected to purchase much of their share of RECs from private customers. Should a utility fail to meet its quota of RECs, it will be assessed a penalty charge for each kilowatt it is deficient. Additional information is available from the New Hampshire Public Utilities Commission website.

Local Option - Property Tax Exemption for Renewable Energy and Electrical Energy Storage

Value:Varies

In New Hampshire, local governments may elect to create property tax exemptions on solar/wind energy systems, electrical storage devices, and wood-burning thermal systems (not fireplaces). Exemptions for each system should be enacted separately rather than all together. Currently, 135 localities have these exemptions within their tax codes. Interested property owners should consult with their local assessor for additional information on the specific statutes that may apply to them.

Enterprise Energy Fund Loans

Value:Varies

The Enterprise Energy Fund is a revolving loan program sponsored by the New Hampshire Community Development Finance Authority (CDFA) and Community Loan Fund (CLF). Commercial property owners can borrow EEF loans to make a variety of energy efficiency upgrades or install new renewable energy systems. Repaid funds immediately "revolve" to another borrower, allowing for perpetual state investment and continued support through interest. Loans from $50,000 to $500,000 may be repaid over 10 years, with variable interest depending on the length of the repayment period and the tax status of the borrower. Nonprofit agencies may receive lower interest rates and more tailored repayment plans. Additional information is available from the CDFA website.

Commercial & Industrial Renewable Energy Grants

Value:Varies

In New Hampshire, large commercial, industrial, nonprofit, or public-sector properties may be eligible for renewable energy grants through the state's Public Utilities Commission. Grants range from $150,000 to $1 million in size and can support new solar, wind, biomass, hydroelectric, or geothermal generation and thermal systems. Finished installations should be interconnected to the electrical grid under a net metering agreement. Additional information is available from the PUC website.

What impacts the cost of solar panels in New Hampshire?

Your Energy Needs -Even though larger solar panel systems are more expensive initially, the average price per watt lowers as the system size grows. For most consumers, installing a system that can generate enough power to reduce their entire electric bill is beneficial, providing significant savings.

Make & Model - There are a range of makes and models of solar panels. Picking an contractor with specific brand preferences means it's even more important important to go with a recommended company. The choice of high-quality models can substantially improve the long-term experience for buyers.

Solar Panel Type - Monocrystalline panels have earned their place as the industry standard, and for good reasons. Even with a higher cost, this technology produce more energy. The majority of installers choose panels constructed using this material.

Your Property - Each property and residence is unique. Issues like uneven land, trees, or other obstructions may add to the complexity of the installation. Currently, most solar installers can assess your home using satellite images and incorporate these elements for the initial cost estimate.

Labor Rates - Companies pay their employees in varying amounts, and these costs are passed down to consumers. It is typical for businesses that offer higher wages to garner better reviews for their services and customer service.

Permitting & Interconnection - Local permitting and utility level interconnection fees differ by area and will impact your final install price. Quality local installers will incorporate these figures into your first estimates to eliminate any surprises.
