New MexicoSolar Incentives 2026: Tax Credits, Rebates & Net Metering

New Mexico offers a 10% state income tax credit on residential solar installations, capped at $6,000. The credit applies to panels, inverters, mounting hardware, and labor. It is non-refundable but can typically be carried forward to subsequent tax years if your liability in the install year is too low to absorb the full credit.

The New Mexico state credit does not stack with a federal residential credit on a 2026 install. That federal credit ended for expenditures made after Dec 31, 2025. On a typical $24,000 installation, the state credit alone is about $2,400.

New Mexico requires investor-owned utilities to offer net metering on residential solar systems. The credit rate is the full retail electricity rate.

In practice, this means a properly sized New Mexico system can drive net annual electricity costs to within tens of dollars of zero. Top utilities operating under NM net metering rules include PNM, El Paso Electric, Xcel NM.

New Mexico credits exported solar at roughly ~100% of retail of the retail rate. See full New Mexiconet metering rates & rollover rules →

No — there is no government program handing out free solar in New Mexico. “Free solar” and “no-cost solar program” ads are leases or power purchase agreements (PPAs): a company owns the panels and bills you for the power. There is no residential federal credit for a 2026 install for either you or the company to claim; a 10% state credit, if any, follows the system owner.

Buying your system — with the incentives in your name — almost always wins on lifetime savings. Read the full breakdown of “free solar” offers →

3 major utilities operate in New Mexico: PNM, El Paso Electric, Xcel NM. Specific rebate availability varies year to year and is typically distributed first-come, first-served until annual budget caps are reached.

Before scheduling any installation, verify current rebate status directly with your utility — programs open and close throughout the year. Most New Mexico installers will pull up-to-date rebate data during a site assessment.

New Mexico excludes the added value of a residential solar system from property tax assessments. A homeowner whose property gains $15,000 in assessed value from a solar install pays no additional property tax on that increase, saving roughly $250 to $400 annually depending on local mill rates.

New Mexico does not exempt solar equipment from sales tax, so installation invoices include standard sales tax on hardware components.
