New MexicoSolar Incentives 2026: Tax Credits, Rebates & Net Metering
New Mexico homeowners can reduce solar installation costs by up to 40% through state and federal incentives. With average monthly bills of $115 and 6.2 peak sun hours per day, the average NM homeowner saves $36,800 over 25 years.
State Solar Tax Credit
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 stacks with the federal 30% Residential Clean Energy Credit. On a typical $24,000 installation, that combination returns roughly $9,600 in combined credits.
Net Metering in New Mexico
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.
Utility Rebate Programs
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.
Property & Sales Tax Exemptions
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.
