Over its life the system generates power at 5.0¢ per kilowatt hour against the 14.12¢ New Mexico utilities charge. That comparison, rather than the sunshine, is what decides it.

The panels are identical in both columns. The only difference is what the utility pays for power you export rather than use, and states have been cutting that. Check what New Mexico requires of your utility before treating the left-hand figure as yours.
The numbers behind it
A 6 kW array at a representative point in New Mexico produces about 10,745 kilowatt hours a year — 1,791 per kilowatt installed. At $3.00 a watt that is $18,000 before the 30% federal credit and $12,600 after it, saving about $1,517 in the first year.
Common questions
Is solar worth it in New Mexico?
A 6 kW system pays for itself in about 7.9 years with full net metering, and around 11.8 years where exports are credited below retail. It generates power at 5.0¢ per kilowatt hour against the 14.12¢ the utility charges.
How much do solar panels produce in New Mexico?
About 1,791 kilowatt hours per kilowatt of panels a year, so a 6 kW system produces roughly 10,745 kWh. Modelled by NREL's PVWatts for a south-facing roof at a representative point in the state.
What does a solar system cost in New Mexico?
About $18,000 before incentives for 6 kW at $3.00 a watt, or $12,600 after the 30% federal tax credit. That credit reduces tax owed rather than the price paid.
Your roof, not the state
The calculator models your own ZIP code rather than a point in the middle of the state, and lets you set the system size, the installed price and the export credit.
Solar payback calculatorProduction modelled by NREL PVWatts for the centroid of New Mexico's ZIP codes, south-facing at 20°. A state is not a point — a centroid can sit in the sunnier half, as it does in states split by mountains, so treat this as the state's middle rather than your address.
