Nashua, NH Solar Panels

Eversource New Hampshire residential customers may receive an upfront incentive of $230 per eligible kilowatt-hour of battery capacity, capped at $3,000. The battery must be on Eversource’s current approved-equipment list, purchased after October 1, 2022, installed, and have permission to operate. Funding is limited, and customers should confirm eligibility and reserve funding through Eversource before purchasing or proceeding.

In exchange, the customer enrolls the battery in demand response for three summer seasons. Events generally occur from June through September, between 3 p.m. and 8 p.m.; the program materials specify that the battery is not discharged below 20% capacity. The program page says there are no annual performance payments, so the principal incentive is the upfront payment.

New Hampshire’s net-energy-metering law allows eligible customer-generators to use their generation to reduce electricity bills and receive credits or compensation for surplus electricity. This is an ongoing bill-credit policy, not a fixed cash rebate, and customers should not assume exported electricity is always credited at the full retail rate. Applicable terms vary by system size, utility tariff, supplier, and interconnection requirements.

Group net metering can allocate credits among eligible customers in the same distribution-utility territory, subject to statutory and utility requirements. Qualifying low- and moderate-income community-solar groups may receive an additional 2.5 cents per eligible kWh of excess production under the applicable rules; this is a project/group tariff benefit, not an automatic additional payment to every participant.

Before sizing or financing a system, confirm the current tariff, export-credit calculation, utility capacity availability, interconnection process, and any supplier-specific conditions with the serving utility. The statute also provides for changes in treatment by system size and rules for carrying forward or paying out certain surplus credits.

New Hampshire allows cities and towns to adopt a local property-tax exemption for qualifying solar-energy systems; it is not automatic statewide. Where adopted, the exemption can remove up to 100% of the increase in assessed value attributable to the system, or use a locally adopted dollar amount. The potential savings depend on the municipality’s adopted policy and the property’s assessment and tax rate.

The system must meet the statutory requirements, including being functioning, and homeowners generally need to apply with the local assessing officials by April 15. For municipalities adopting or readopting the exemption on or after January 1, 2020, the statutory definition includes solar PV panels, inverters, and storage. Confirm the town’s adoption, covered equipment, amount, application form, and deadline with the local assessor.

New Hampshire law authorizes municipalities to exempt qualifying electric-storage equipment from property taxation, but a town or city must adopt the exemption and determines its local terms. Eligible equipment generally includes behind-the-meter storage used for purposes such as reducing peak loads or supporting renewable generation or grid services. Conventional electric-resistance or gas domestic water heaters are excluded from the statutory storage definition.

The financial benefit varies with the municipality’s adopted exemption and the value assigned to the qualifying equipment. Some solar-plus-storage systems may also fall within a locally adopted solar-system exemption, depending on the applicable statute and adoption date; exemptions should not be assumed to stack. Ask the local assessor which provision applies, what equipment is covered, and whether an application or annual filing is required.
