New Mexico Solar Overview
New Mexico is among the top solar states in the country, and in 2026, it remains one of the few states with an active, meaningful state-level tax credit. The New Solar Market Development Tax Credit provides 10% of installed costs back to the homeowner as a refundable state income tax credit, up to $6,000 per year. That's real money in your pocket, even if you owe little or no state income tax.
Add to that a gross receipts tax exemption on equipment and installation labor (New Mexico's version of a sales tax), a 100% property tax exemption, and full retail net metering credits that roll over month-to-month with no expiration, New Mexico offers a complete stack of state-level incentives that remains largely intact even after the federal ITC expired December 31, 2025.
With over 300 sunny days per year and 6.5+ peak sun hours in much of the state, New Mexico systems generate more energy per panel than most of the country. The combination of high production and a strong incentive stack makes New Mexico one of the most financially compelling solar markets remaining after the federal ITC sunset.
New Solar Market Development Tax Credit
This is the headline incentive for New Mexico solar in 2026. The credit is administered by the New Mexico Energy, Minerals and Natural Resources Department (EMNRD) and the New Mexico Taxation and Revenue Department.
| Credit Feature | Detail |
|---|---|
| Credit percentage | 10% of purchase and installation costs |
| Maximum credit | $6,000 per taxpayer per tax year |
| Refundable? | Yes, fully refundable for tax years 2022 and later |
| Annual state pool | $30 million, awarded first-come first-served |
| Eligible systems | Solar PV and solar thermal; batteries may qualify when paired |
| Apply by | December 31 of the year following installation |
| Eligible property | Residential, commercial, agricultural; tribal lands and leaseholds |
| Program runs through | Installations through December 31, 2031 |
| Admin agency | clean.energy.nm.gov, EMNRD (Tier 1) |
Because the credit is refundable, you don't need to owe $6,000 in state taxes to capture its full value. If your state tax liability is $1,500 and you earn a $6,000 credit, the state sends you a $4,500 refund check. This makes the credit accessible to retirees, low-income homeowners, and anyone with modest state tax liability.
The $30 million annual pool can be fully subscribed in busy years. Apply as early in the year as possible after installation, the certificate of eligibility must be obtained before claiming the credit on your state tax return. Visit clean.energy.nm.gov to apply.
Note: A 2026 Senate bill (SB 55) proposed increasing the credit to 30% with a $15,000 cap. It passed the Senate 26-10 but stalled in the House (action postponed indefinitely, February 2026). The current 10% / $6,000 structure remains in effect.
Gross Receipts Tax Exemption
New Mexico uses a gross receipts tax (GRT) in place of a traditional sales tax. Solar equipment and installation labor are exempt from GRT, meaning the exemption applies to the entire job, materials, panels, inverters, racking, wiring, and labor. Battery storage may qualify only if included in the solar energy system as defined in statute; confirm GRT treatment with your installer.
This exemption is applied automatically at point of sale by licensed solar contractors. Unlike some states where homeowners must file paperwork, no separate exemption form is required from you, your installer should apply it when pricing the job. Confirm that your contractor's quote reflects the GRT exemption.
Net Metering in New Mexico
Under PRC rule 17.9.570 NMAC, New Mexico utilities credit excess generation from systems of 10 kW or less either as kWh carried forward month to month or at the utility's avoided cost rate; check your utility's election. Credits roll over month to month with no expiration, an important benefit in a high-solar state where production often exceeds consumption in spring and fall months.
| Utility | Service Territory | NEM Cap | Credit Rate |
|---|---|---|---|
| Public Service Company of NM (PNM) | Albuquerque, Santa Fe, Rio Rancho | 10 kW (retail); larger at avoided cost | Full retail (≤10 kW) |
| El Paso Electric (EPE) | Las Cruces, El Paso area | 120% of annual consumption | Full retail rate |
| Xcel Energy (SPS) | Eastern New Mexico, Roswell area | 10 kW (retail); larger at avoided cost | Full retail (≤10 kW) |
| Rural Electric Cooperatives | Various rural areas | Varies by co-op | Confirm with your co-op |
For systems larger than 10 kW with PNM or Xcel, excess generation beyond the system cap is credited at the avoided cost rate rather than full retail. System sizing to match your consumption is advisable for customers in those territories to maximize the value of full retail credits.
PNM Solar Renewable Energy Credits (SRECs)
PNM's REC incentive program was discontinued by the PRC on December 31, 2022; only existing agreements continue to their end dates. PNM pays $0.0025 per kWh (one-quarter cent) for solar renewable energy credits over an 8-year contract term. Payments are issued once accumulated credits exceed $20. While modest, this is an additional revenue stream on top of net metering credits. Contact PNM directly to confirm current SREC program availability and rates.
Property Tax Exemption
New Mexico provides a 100% property tax exemption for solar energy systems. The value added to your home by the solar installation is entirely excluded from your property's assessed value under state statute. This exemption is permanent, automatic, and requires no application from the homeowner.
The practical effect: a solar system that adds $20,000 to your home's market value generates zero increase in your annual property tax bill. Over a 25-year system lifetime, this can represent several thousand dollars in avoided property taxes depending on your local mill levy.
New Mexico offers tax benefits at every stage: no gross receipts tax when you buy the system, a refundable state income tax credit when you file taxes, and no property tax increase for the lifetime of the installation. This is one of the most comprehensive state-level tax exemption stacks in the nation.
Payback Analysis (2026)
New Mexico's combination of exceptional solar resources, the 10% state credit, GRT exemption, and retail net metering produces some of the best payback periods in the country post-ITC. A well-sized system in Albuquerque or Santa Fe can achieve sub-10-year payback even without the federal credit.
With a system sized to maximize self-consumption (common in Albuquerque where summer AC loads are high), the effective savings rate can be even better. Adding battery storage improves evening self-consumption, though NM currently has no specific residential battery incentive.
Right-sizing note: for PNM customers with systems over 10 kW, excess exports above the cap earn avoided-cost rates rather than retail. An 8 kW system sized to roughly match a 700 to 800 kWh/month household captures the maximum retail NEM credit efficiently.
