Introduction
The solar incentive landscape changed significantly at the end of 2025. The federal residential solar tax credit — which had given homeowners a 30% deduction on installation costs for years — expired on December 31, 2025, eliminated by the One Big Beautiful Bill Act signed in July 2025.
For New Mexico homeowners considering solar in 2026, this raises an obvious question: does going solar still make financial sense?
The short answer is yes — and here’s why.
New Mexico still has meaningful incentives in place, one of the sunniest climates in the country, and rising utility rates that make the long-term math of solar ownership as compelling as ever. This guide breaks down exactly what’s available right now and what it means for your decision.
What Changed: The Federal Tax Credit Is Gone for Homeowners
The federal Residential Clean Energy Credit (Section 25D) provided homeowners with a 30% tax credit on solar installation costs from 2022 through 2025. On a $25,000 system, that was $7,500 back in your pocket.
That credit no longer exists for residential customers purchasing systems in 2026 and beyond.
Important note for business owners: The federal commercial solar Investment Tax Credit (Section 48E) is still in effect at 30% through 2027. If you’re considering solar for your business, farm, or commercial property, the federal credit still applies — and now is an especially strong time to move.
What’s Still Available: New Mexico Solar Incentives in 2026
1. New Mexico Solar Market Development Tax Credit (SMDTC)
This is the most significant financial incentive still available to New Mexico homeowners in 2026.
What it is: A state tax credit equal to 10% of the cost to purchase and install a solar system, up to a maximum of $6,000 per taxpayer per year. Critically, this credit is refundable — meaning if the credit exceeds what you owe in state taxes, the New Mexico Taxation and Revenue Department will send you the difference as a refund.
Who qualifies: New Mexico residents who purchase and install a solar thermal or photovoltaic system. The credit is available for systems installed through December 31, 2031.
How to claim it: After your system is installed, you must apply to the New Mexico Energy, Minerals and Natural Resources Department (EMNRD) for a certificate of eligibility. Once issued, you claim the credit when filing your New Mexico state taxes.
One important caveat: The SMDTC has an annual allocation cap of $30 million. Applications are processed on a first-come, first-served basis, and credits can be waitlisted if the cap is reached for the year. Apply promptly after installation to secure your position.
For a typical $25,000 system, the New Mexico state credit returns up to $2,500 (10% of $25,000, well under the $6,000 cap).
2. Net Metering Through PNM and Other NM Utilities
Net metering is not a tax credit, but it’s one of the most valuable ongoing financial benefits of going solar in New Mexico.
Under net metering, any electricity your solar system produces but doesn’t immediately use gets sent back to the grid. Your utility — PNM, El Paso Electric, or others depending on your area — credits your account for that energy at the retail rate.
In New Mexico, these credits roll over month to month, which is especially valuable given the seasonal nature of solar production. The long summer days generate surplus credits you can draw on during shorter winter months.
Over a 25-year system life, net metering can represent tens of thousands of dollars in avoided electricity costs.
3. No New Mexico Gross Receipts Tax on Solar Equipment
New Mexico exempts solar energy equipment from gross receipts tax (the state’s equivalent of sales tax). This means the panels, inverters, racking, and other hardware in your installation aren’t subject to this tax — a quiet but real savings on a large purchase.
4. Property Tax Exemption
In New Mexico, the added value a solar system brings to your home is exempt from property tax assessment. Studies consistently show solar increases home resale value by 3–4% — but that increase won’t raise your annual property tax bill.
Does Solar Still Make Financial Sense in New Mexico Without the Federal Credit?
Yes — though the math looks slightly different than it did in 2025.
Here’s a simplified comparison for a typical Albuquerque homeowner:
Typical system: 8kW residential solar installation
Estimated cost: $24,000–$28,000 before incentives
NM state tax credit: Up to $6,000 (10%, capped)
Effective cost after state credit: ~$18,000–$22,000
Estimated annual electricity savings: $1,500–$2,000 (based on PNM rates and NM solar production)
Estimated payback period: 9–13 years
Without the federal credit, payback periods are longer than they were in 2024 or 2025. But over a 25-year system life — with panels still producing at 85%+ efficiency — the total savings remain substantial. And with PNM rates having increased significantly in recent years and likely to continue rising, the hedge value of locking in your energy production is more relevant than ever.
What About Solar Leases and PPAs?
Some solar companies offer leases and power purchase agreements (PPAs) — arrangements where you don’t own the panels but agree to pay a monthly fee or per-kilowatt-hour rate in exchange for using the power they generate.
Under current law, leased systems technically still have access to the federal commercial ITC (since the leasing company owns the system and can claim the credit, sometimes passing savings to the customer through lower rates).
SunState Solar does not offer leases or PPAs. We believe system ownership delivers significantly better long-term value — you build equity, capture the full benefit of net metering credits, and increase your home’s resale value. Our $0 down solar loan options let you own your system from day one with no upfront cost.
The Bottom Line for New Mexico Homeowners in 2026
The removal of the federal residential tax credit is a meaningful change, and any solar company that isn’t being upfront about it isn’t being honest with you.
What hasn’t changed: New Mexico is still one of the best states in the country for solar. 300+ sunny days a year, a meaningful state tax credit, strong net metering policy, and rising utility rates all point in the same direction. Solar ownership in New Mexico still makes long-term financial sense — the timeline to payback is just a bit longer than it was last year.
