| Installed cost (before incentives) | $21,000 |
| Estimated annual savings | $1,444 |
| Payback period | 14.5 years |
| 25-year net savings | +$13,009 |
Figures use New Hampshire average prices, a 7 kW system at $3.00/watt, 50% self-consumption at retail plus a conservative 9¢/kWh net-metering credit, and ~0.5%/yr panel degradation. Sources: EIA electricity prices and NREL PVWatts production modeling.
What this means for New Hampshire homeowners in 2026
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in New Hampshire carries the full upfront cost unless a state or utility incentive applies. Because New Hampshire electricity costs well above the national average, the payback case is more marginal — strongest for high electricity users, south-facing roofs, and homeowners who plan to stay long term.
