New Mexico solar cost & savings (typical 7 kW system)
| Metric | Estimate |
|---|---|
| Annual production | 11,900 kWh |
| Installed cost (before incentives) | $21,000 |
| Estimated annual savings | $1,369 |
| Payback period | 15.3 years |
| 25-year net savings | +$11,236 |
Figures use New Mexico 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 Mexico homeowners in 2026
The 30% federal residential solar tax credit (Section 25D) expired December 31, 2025, so a 2026 installation in New Mexico carries the full upfront cost unless a state or utility incentive applies. Because New Mexico electricity costs around 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.
