What New Mexico still offers after the federal credit ended
Every incentive on this page is verified against New Mexico government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - San Ysidro systems completed in 2026 get $0 from it.
Under New Mexico's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for San Ysidro homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in San Ysidro tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: New Mexico's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

New Mexico rules that decide your payback
| Rule | New Mexico status |
|---|---|
| Export compensation (net metering) | New Mexico utilities under PRC jurisdiction must offer net metering under 17.9.570 NMAC, where the net energy delivered from the customer's qualifying facility to the utility is purchased at the utility's applicable time-of-use or single-period energy rate, with a net amount owed the customer of less than $50 carried over to the following billing period and $50 or more paid out before the end of the next billing period. |
| State incentive | New Solar Market Development Tax Credit (Section 7-2-18.31 NMSA 1978) - up to 10% of purchase and installation costs, not to exceed $6,000, for qualified photovoltaic or solar thermal systems installed before December 31, 2032; refundable and transferable, requires a certification of eligibility from EMNRD, and is subject to an annual statutory funding cap. |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
New Mexico's credit is refundable AND transferable - any amount above the homeowner's tax liability is refunded (for systems installed from 2022 onward), and the credit can be sold or transferred to another taxpayer - but it is first-come, first-served: EMNRD denies applications received after each year's statutory cap is met, and the homeowner must apply within 12 months following the calendar year of installation.

What this means for San Ysidro roofs
Whether solar still pays in New Mexico after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting San Ysidro quotes
The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

Common questions
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
