Buying a Home With Solar Panels in New Hampshire (2026)

It depends on the town. Under RSA 72:62, each NH municipality can vote to adopt a local property tax exemption for solar energy systems. Approximately 66% of NH towns (about 200 of 300+ municipalities) have adopted this exemption. In those towns, the assessed value added by the solar system is fully exempt from property taxation. In the remaining 34% of towns, solar panels WILL increase your property tax assessment. Before buying a solar home, verify the exemption status with the town assessor — this is not automatic and must be applied for.

NEM 2.0 net metering in New Hampshire credits solar production at 100% of supply charges, 100% of transmission charges, and 25% of distribution charges. When you purchase a home with solar, the interconnection agreement transfers with the property address. You establish a new utility account and the NEM 2.0 credits begin accruing to your account. Any accumulated credits from the previous owner stay with their account — you start fresh. NEM 2.0 rates are locked through 2041 for existing systems, giving the new owner 15+ years of guaranteed credit rates.

The Community Power Coalition of NH (CPCNH) allows towns to aggregate electricity purchasing. If you buy a solar home in a CPCNH town, your net metering credits apply to the community power rate rather than the default Eversource, Liberty, or Unitil supply rate. CPCNH rates have historically been lower than utility default supply rates, which means your net metering credits may be calculated against a lower supply charge. However, the overall economics can still be favorable because CPCNH can offer stable rate structures. Verify whether the seller was on community power or default supply, as this affects the credit calculation.

Search the NH Secretary of State UCC filing database for any UCC-1 filings against the property address. A filing from a solar company (Sunrun, Vivint, Tesla, etc.) indicates a lease or PPA. Also request the original solar agreement from the seller and check the property deed for any solar-related encumbrances. Your title search during closing should flag solar liens. In NH, owned systems are more common than leased due to the state's lack of a solar lease marketplace — but always verify independently.

No, you do not need to re-apply for interconnection. The interconnection agreement is tied to the meter and property address, not the account holder. When you open a new utility account at the address, the existing interconnection carries over. However, you should contact your utility (Eversource, Liberty, or Unitil) to confirm the net metering arrangement is active on your new account. The system's production meter remains in place. This process typically takes 1-2 weeks after you establish service.

Battery storage adds significant value in rural NH where power outages are common, especially for homes on well water (no electricity = no water). Check the battery warranty (typically 10 years), current state of health (cycle count and capacity retention), and whether the battery is on a separate lease from the solar panels. Verify the battery is properly permitted and covered by the interconnection agreement. In NH, batteries that can island (disconnect from grid during outages) provide critical well pump backup — confirm the system is configured for this if the home has a well.

Yes, ground-mount systems are very common in rural NH where properties have ample acreage. Ground-mount systems are considered fixtures of the real property and transfer with the home sale just like roof-mounted panels. During due diligence, verify that the ground-mount has proper setback compliance with local zoning (typically 10-25 feet from property lines), that any underground conduit is mapped, and that the interconnection agreement covers the ground-mount configuration. Ground-mount systems are easier to inspect than roof-mount and typically have better airflow for cooling.

NHSaves is the statewide energy efficiency program funded by all NH ratepayers through their utility bills. As a new homeowner, you gain access to NHSaves programs including home energy audits ($100 copay for comprehensive assessment), insulation rebates (75% up to $8,000), and heat pump rebates. These programs complement your solar system — adding insulation reduces your total energy needs, which means your solar system covers a larger percentage of your bill. NHSaves programs are available regardless of whether the home already has solar.

Owned solar panels add approximately 4.1% to home value according to Zillow research. On New Hampshire's median home price of approximately $420,000, that translates to about $17,220 in added value. This premium is strongest in southern NH and the Seacoast where electricity rates are highest ($0.25-0.28/kWh). Leased solar panels add minimal value because the buyer inherits monthly payments rather than a free-and-clear asset. In some cases, leased panels can make a home harder to sell.

Key NH-specific red flags include: the town has NOT adopted RSA 72:62 (meaning solar increases your property tax), UCC filings indicating a lease when the seller claims the system is owned, a system installed by a company that no longer operates in NH (orphaned system with no local workmanship warranty), the home is in a CPCNH town but the seller has not disclosed community power implications, the roof needs replacement within 5-10 years (panel removal and reinstallation costs $3,000-5,000), no monitoring data available, and for rural properties — the battery system is not configured to back up the well pump during outages.
