Is solar worth it in New Mexico?
Short answer for a typical New Mexico home: a strong payback — roughly 7.4 years to break even after the 30% credit. Run your own bill through the calculator below.
New Mexico gets excellent sunshine — about 6.5 peak sun hours a day — and residential electricity runs around $0.15/kWh. For a typical $150-a-month power bill, that points to roughly a 6.3-kW system costing about $13,277 after the 30% federal tax credit, paying for itself in about 7.4 years and netting on the order of $48,088 over 25 years. Your own numbers will differ — the calculator above uses your real bill.
New Mexico has superb sunshine and a state tax credit on top of the federal one, so systems produce heavily and net cost is low. Payback is generally quick despite moderate electricity rates.
What changes the math in New Mexico
- Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. New Mexico sits at about $0.15.
- Sun hours — more sun means a smaller, cheaper system covers the same usage. New Mexico averages ~6.5 hours.
- Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
- Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.
