Why solar in Farmington

Almost every account of New Mexico solar describes PNM, and Farmington is not on PNM. The city runs its own municipal utility, which means the PNM net metering arrangement, the 10 kW AC credit threshold and the approved purchase rate above it are terms of somebody else tariff. The state-level incentives still apply to you; the utility-level ones have to be established locally.

The state incentives travel, the utility terms do not

The Solar Market Development Tax Credit, the gross receipts tax deduction and the property tax exemption are all state provisions. They apply wherever you are in New Mexico, regardless of which utility bills you.

Net metering terms are different. The PNM arrangement, including the 10 kW AC threshold under which kilowatt hour credits do not expire, is a PNM tariff rather than a statewide rule.

A municipal utility sets its own export compensation, its own system size limits, its own interconnection process and fees. Those may be more generous than PNM or less.

So the first step with any Farmington quote is to separate the two. State-level lines can be checked against state rules; utility-level lines have to be checked against your own utility.

The questions for your own utility

Ask how exported electricity is compensated and at what rate, and whether netting happens instantaneously, monthly or annually. That distinction matters more than most equipment choices.

Ask whether excess credits carry forward, whether they expire, and if so on what date. An annual forfeit date changes how a system should be sized; the absence of one changes it back.

Ask what system size limits apply, what the interconnection application involves and costs, and how long approval typically takes.

Ask whether the utility runs any programme of its own for solar customers and whether any solar-specific charge applies. Get the answers in writing from the utility rather than from a sales conversation.

Reconciling the quote with those answers

Check whether the projection used your utility export terms or PNM ones, and whether it used your actual retail rate. Both are commonly imported from a statewide template.

Check the state credit line says 10 percent capped at $6,000, not the 30 percent that Senate Bill 55 would have created before action on it was postponed indefinitely on February 12, 2026.

Check the gross receipts tax is absent from the price, and that the projection does not show a property tax increase for the array.

If the quote cannot be reconciled with what your utility told you, that discrepancy is the most useful thing you have learned. Ask for it to be rebuilt rather than explained away.

What a projection here needs to contain

The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase receives no federal tax credit. Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements.

The state Solar Market Development Tax Credit at 10 percent up to $6,000 applies regardless of your utility, subject to the $30 million annual cap and the one-year application window, as do the gross receipts tax deduction and the property tax exemption.

Everything at utility level comes from your own utility: the retail rate, export compensation, netting method, credit expiry, size limits and interconnection.

Ask your utility directly, then ask your installer to rebuild the projection from those answers rather than from a PNM template.

Net metering: Retail-rate net metering, with a 10 kW AC threshold at PNM

New Mexico credits exported solar generation at the retail rate, which after the changes made in many other states is now a genuine advantage. The detail that should shape a design is the threshold in the PNM arrangement. For systems of 10 kW AC or less, excess generation accumulates as kilowatt hour credits applied to future bills, and those credits do not expire while the account remains open. There is no annual true-up date at which unused credit is forfeited or donated, which is unusual and valuable. For systems larger than 10 kW AC, the treatment changes: rather than banking kilowatt hour credits, the customer is paid monthly for excess generation at the utility approved purchase rate, which is below the retail rate. So crossing 10 kW AC is not a gradual change in economics, it moves you onto a different and less favourable basis for everything you export. A design that lands just above the threshold should be examined closely, and one that lands just below it is often the better engineering answer. Other New Mexico utilities set their own arrangements, and municipal utilities in particular sit outside the investor-owned utility rules entirely, so confirm what applies at your address.

Why solar + battery in Farmington

New Mexico is one of the few states where a residential solar buyer still has a real state incentive after the federal credit ended, and it stacks with excellent sun and retail-rate net metering. The Solar Market Development Tax Credit gives 10 percent of the purchase and installation cost up to $6,000 per taxpayer per taxable year, administered by EMNRD and claimed through New Mexico Taxation and Revenue. Solar equipment and installation labour are also deducted from gross receipts tax, and the value a system adds to a property is fully exempt from property tax. Two cautions. The credit runs against an annual aggregate cap of $30 million per calendar year through 2031, first come first served, so it can run out. And Senate Bill 55, which would have raised the credit to 30 percent with a $15,000 cap, did not pass: action was postponed indefinitely on February 12, 2026, so the rate remains 10 percent regardless of what a sales conversation may suggest.

Frequently asked questions

Do PNM net metering rules apply in Farmington?

No. Farmington runs its own municipal utility, which sets its own export compensation, size limits and interconnection process. The PNM 10 kW AC credit threshold and approved purchase rate are PNM tariff terms rather than statewide rules.

Do I still get the state tax credit?

Yes. The Solar Market Development Tax Credit, the gross receipts tax deduction and the property tax exemption are all state provisions and apply regardless of which utility bills you.

What should I ask my municipal utility?

How exports are compensated and at what rate, whether netting is instantaneous, monthly or annual, whether credits carry forward or expire and on what date, what size limits apply, and what interconnection involves, costs and takes.

What if my quote used PNM figures?

Ask for it to be rebuilt on your utility actual terms. A quote that cannot be reconciled with what your utility told you is describing a different tariff, and that discrepancy is worth resolving before anything else.
