For a typical 10.49 kW system in New Hampshire
Multi-plane roofs, steep pitches, tile or slate surfaces, and older roofs needing reinforcement all increase labor and mounting costs.
Larger systems have a lower per-watt cost thanks to volume discounts. A 12 kW system typically costs less per watt than a 5 kW system.
Premium panels (REC, Maxeon) and microinverters (Enphase) cost more upfront but deliver better long-term performance and warranties.
Permit fees, inspection requirements, and interconnection timelines vary by municipality in New Hampshire and can affect total project cost.
The Section 25D Residential Clean Energy Credit expired December 31, 2025. Homeowner cash or loan purchases receive $0 federal tax credit in 2026. Third-party owned systems (solar lease or PPA) still qualify for the 30% ITC under Section 48/48E.
New Hampshire does not currently offer a state-level solar incentive or tax credit. However, a solar lease or PPA lets you go solar with $0 down while the system owner claims the 30% commercial ITC under Section 48/48E — savings that get passed to you through lower rates. This is often the best path for New Hampshire homeowners in 2026.
