Is there still a solar tax credit for Grenville homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Grenville: New Mexico's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Grenville systems completed in 2026 get $0 from it.
Installed home solar for Grenville homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Grenville, New Mexico has about 24 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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 Grenville 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.

The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts 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 Grenville roofs
The honest 2026 answer for Grenville: 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 Grenville 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
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.
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.
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.
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.
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.
