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 - Williamsburg 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 Williamsburg homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.

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 Williamsburg roofs
The honest 2026 answer for Williamsburg: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is New Mexico's export compensation, covered in the net metering section.

Getting Williamsburg quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
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.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
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.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
