Is solar worth it in New Mexico?
New Mexico combines a 10% state tax credit with some of the best sunshine in the nation for a strong Southwestern payback. At an average residential rate of about ~14¢/kWh, every kilowatt-hour your panels produce is a kilowatt-hour you don't buy from the utility — and that avoided cost is what drives your payback. Combined with excellent sunshine, a standard 7 kW system in New Mexico generally pays for itself in 8–11 years after the 30% federal credit, then delivers a decade or more of nearly free power.
To see your own number rather than this state average, plug your actual electric bill into the Solar Payback Calculator. If you're weighing how to pay, the Financing Calculator compares cash, loan and lease side by side.

Net metering in New Mexico
New Mexico uses Net metering (full retail). Net metering is the second-biggest factor in your solar economics after your electricity rate, because it determines how much credit you earn for the excess power your panels send back to the grid. Generous, full-retail net metering shortens payback; reduced export rates lengthen it and increase the value of pairing your system with a home battery.
