Solar Panels in New Mexico: Cost, Payback & ROI (2026)
Is solar still worth it in New Mexico after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 13.8¢/kWh New Mexico electricity rates for a typical home using 900 kWh/month.
Section 25D (30% federal solar tax credit) expired December 31, 2025
All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in New Mexico in 2026?
New Mexico has one of the best solar resources in the country at 1,900 kWh/kW/year — tied with Arizona and Nevada — and the state's electricity rates of 13.8¢/kWh are moderate. The combination of strong sun and New Mexico's aggressive renewable energy mandates makes solar increasingly attractive. PNM and El Paso Electric have different net metering structures; confirm retail-rate credits with your specific utility.
For a typical New Mexico home consuming 900 kWh per month, our calculation shows a 5.7 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $16,768 gross before any state rebates. Year-one savings of $1,490 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).
The 10.3 years payback period is moderate — within the national average range of 8–12 years. Over 25 years — the standard warranty period for most premium panels — a New Mexico homeowner following this profile would save an estimated $47,662 total, for a net benefit of $30,893 after recovering the system cost.
