What solar incentives are available in New Hampshire?
New Hampshire solar incentives vary by utility and program year — your installer should walk you through every rebate, tax credit, and net-metering option that applies to your address. The federal residential 25D credit expired December 31, 2025.
How do I verify a solar contractor's license in New Hampshire?
Every state maintains a contractor licensing database — typically operated by the state's Department of Consumer Affairs, Contractors State License Board, or Board of Electrical Contractors. Ask the contractor for their license number and verify it directly. Top Solar Services confirms license status before issuing the Verified or Premier Verified badge.
Is solar worth it in New Hampshire without the federal tax credit?
For many New Hampshire homeowners, yes — particularly where retail electricity rates are high, net metering exists at retail or near-retail rates, and state rebate or SREC programs apply. The federal residential 25D credit expired December 31, 2025, which has stretched typical payback periods, but lifetime savings on a 25-year system remain positive in most cases. Solar leases and PPAs (third-party owned systems) may still capture the commercial 48E credit indirectly through pricing.
