The federal residential tax credit is dead in 2026. State incentive programs — from NJ SuSI ($90/MWh for 15 years) to MA SMART (monthly bill credits) — are now the main way to reduce your solar cost.
New Hampshire Solar Incentives Overview
New Hampshire has no state solar rebate (repealed by SB 303 in 2024) and no residential ITC (expired 2025). However, NEM 2.0 provides ~85% of retail rate credits locked through 2041, ~66% of towns offer property tax exemptions under RSA 72:62, and NH has no sales tax. With $0.27/kWh rates, payback is ~9.5 years.
