New Hampshire Solar Market Analysis
New Hampshire homeowners face electricity rates of $0.24/kWh, positioning solar as a practical investment despite the state's moderate 4.2 peak sun hours per day. At the current 2026 installed cost of $3.3/W, a typical residential system generates strong returns over its 25- to 30-year lifespan. After accounting for the 30% federal Investment Tax Credit, most New Hampshire installations achieve payback within 7 to 9 years, leaving two decades of energy production at minimal operating cost.
State-level incentives strengthen the financial case considerably. The Residential Renewable Electrical Generation Rebate provides a direct $1,500 incentive, while the Property Tax Exemption shields system value from local property assessments. Equally important, Eversource and Liberty Utilities honor net metering agreements, allowing homeowners to credit excess generation back to the grid at retail rates. These programs—combined with federal tax benefits—substantially reduce upfront costs and accelerate the path to positive cash flow.
