PNM Net Metering in Albuquerque: How Solar Buyback Works

PNM credits excess solar electricity at the full retail rate — currently around 15–16 cents per kWh — and rolls those credits forward month to month with no expiration, as long as your system's inverter capacity is 10 kW-AC or less. That 1:1 retail credit is the single biggest driver of solar savings in Albuquerque in 2026, now that the federal 30% Residential Clean Energy Credit (Section 25D) expired on December 31, 2025.

How Does PNM Net Metering Actually Work?

Every PNM customer with a grid-tied solar system gets two-way metering under New Mexico Public Regulation Commission Rule 570 (NMAC 17.9.570). The concept is simple: your meter tracks electricity flowing in both directions. When your panels produce more than your home uses — on a sunny April afternoon in the North Valley, for example — the surplus flows onto the grid and your meter runs backward. At the end of the billing cycle, PNM nets what you consumed against what you exported and bills you (or credits you) only for the difference.

The practical result: a well-sized system in Albuquerque can reduce a PNM bill from $150 a month to a few dollars in connection fees, and summer overproduction banks credits that offset the higher-consumption months of July and August when your evaporative cooler or mini-split runs hard.

According to PNM's published interconnection tariff, the program splits into two tiers based on inverter size:

For most Albuquerque homeowners — whose systems run 6–10 kW — the Small PV Program applies, meaning every exported kilowatt-hour earns a full retail credit that never expires.

What Is the Net Metering Credit Worth in Albuquerque?

The value of a PNM net metering credit is tied directly to the retail rate, so it rises whenever PNM raises rates — and PNM has raised rates several times over the past decade. As of June 2026, the cost of electricity in Albuquerque is 16 cents per kilowatt-hour, according to EnergySage's analysis of real customer bills.

That might sound modest compared to California or Massachusetts, but Albuquerque's solar resource is extraordinary. According to NREL PVWatts data, Albuquerque averages 6.77 peak sun hours per day, one of the highest figures for any major U.S. city. At that resource level, a 1 kW of installed solar capacity produces roughly 1,765–1,805 kWh per year — before accounting for any shading or soiling losses specific to your roof.

Here is what that looks like for typical Albuquerque system sizes:

These are estimates based on NREL production data and current PNM rates. Actual production varies by roof pitch, azimuth, shading, and panel degradation. The figures assume a south-facing, unshaded installation — common in Albuquerque's ranch-style and pueblo-revival homes.

Do PNM Solar Credits Roll Over or Expire?

This is one of the most misunderstood parts of net metering, and the answer for PNM Small PV customers is unambiguously good: the credits never expire.

Under the Small PV Program (≤ 10 kW-AC), PNM tracks your surplus as a "Cumulative Renewable Energy Credit" measured in kWh on your account. Every billing period, PNM subtracts what you consumed from your kWh bank before billing you any cash charges. If you build up 1,200 kWh of credits in May and June — a realistic outcome for an 8 kW Albuquerque system — those credits remain on your account through the fall and winter, offsetting higher heating or lighting bills when sun hours drop.

The only time those credits convert to cash is when you close your PNM account. At that point, PNM pays out any remaining balance at Rate 12, which is PNM's avoided-cost rate — a much lower figure than retail. That asymmetry is why right-sizing your system matters: a system so large it perpetually over-generates will bank more credits than you can use, and the eventual Rate 12 payout will be well below retail value.

The practical rule for Albuquerque homeowners: size your system to offset 90–105% of your annual kWh consumption. That way you use the rollover feature as a seasonal buffer (exporting in spring, drawing down in summer and winter) rather than accumulating a surplus that ultimately gets cashed out at wholesale rates.

What Incentives Reduce the Cost of Going Solar in 2026?

The federal tax credit landscape changed significantly at the end of 2025. Here is the honest picture:

Federal Section 25D — Expired. The 30% Residential Clean Energy Credit for homeowner-purchased solar systems expired December 31, 2025. If you buy or finance a system outright in 2026, there is no federal income tax credit available to you.

Third-party ownership (lease/PPA) — Federal 48E still active. If a solar company owns the panels on your roof under a Power Purchase Agreement or lease, the company claims the commercial investment tax credit (Section 48E) and may pass a portion of that value to you through lower PPA rates. This structure is worth evaluating if your tax situation makes the state credit less useful.

New Mexico Solar Market Development Tax Credit — Very much alive. New Mexico's own credit is the headline incentive for 2026. According to EMNRD's program page, the credit covers 10% of installed equipment and labor costs, up to $6,000 per taxpayer, and is refundable — meaning if the credit exceeds your NM income tax liability, you receive the difference as a cash refund.

One important timing note: EMNRD's program runs on a first-come, first-served basis against a $30 million annual cap. The cap has been reached before applications stopped in prior years. Submit your EMNRD application promptly after your system passes inspection — don't wait until tax season.

The NM credit is active for systems installed through 2031, so you are not under a short deadline. But the annual cap creates a real reason to act earlier in the calendar year rather than later.

To see how these incentives interact with payback math for a specific system size, our breakdown of New Mexico solar tax credits in 2026 walks through the arithmetic in detail.

Does New Mexico Have SRECs?

Solar Renewable Energy Certificates (SRECs) — where you earn one tradeable certificate per megawatt-hour your system generates and sell them to utilities — are common in states like New Jersey and Massachusetts. New Mexico's SREC market is effectively dormant for residential systems. The state's Renewable Portfolio Standard does not create the kind of active SREC marketplace that drives meaningful income in those other states, and most Albuquerque homeowners should not factor SREC income into their financial projections.

PNM does operate a separate Solar*Rewards program for renewable energy credits (RECs). Participation is optional and involves a one-time application fee ($100 for Small PV systems under 10 kW). Under Solar*Rewards, you can choose to have your REC value rolled into your cumulative kWh credit bank, or request an annual cash payout at PNM's "average hourly incremental cost" — effectively a wholesale/avoided-cost rate considerably below retail. For most homeowners, the kWh rollover option is more valuable than the cash payout, since retail-rate offset math favors keeping credits on your account.

The bottom line: don't select a solar company based on promises of significant SREC income in New Mexico. Net metering and the state tax credit are the real financial engines here.

How Net Metering Affects Your Payback Period in Albuquerque

Without the 30% federal credit, the math looks different than it did in 2024. But Albuquerque's combination of high sun, retail-rate net metering, and the state credit still produces reasonable payback timelines.

A realistic scenario for a typical Albuquerque home:

• System size: 8 kW (common for a 2,000–2,500 sq ft home in neighborhoods like Nob Hill, Four Hills, or Rio Rancho's westside)
• Installed cost: ~$20,000–$24,000 (before incentives, at ~$2.50–$3.00/W installed)
• NM state credit: –$6,000 (maximum, assuming sufficient NM income tax liability or refund)
• Net cost: ~$14,000–$18,000
• Annual production: ~14,100–14,400 kWh
• Annual bill offset value: ~$2,256–$2,304 (at 16¢/kWh)
• Simple payback: approximately 6–8 years

These are ranges, not guarantees. Your actual payback depends on your roof's orientation (south-facing beats east/west by 10–20%), shading from mature trees or neighbor structures, your household's consumption pattern, and future PNM rate changes. If PNM rates rise — which is the historical trend — the payback shortens, because your net metering credits become worth more per kWh.

Pairing solar with a battery like the Enphase IQ Battery or Tesla Powerwall adds cost but provides outage resilience that net metering alone does not. For a comparison of those tradeoffs, see our guide to solar battery backup in New Mexico.

Frequently Asked Questions

What is PNM's net metering credit rate per kWh?

PNM credits exported solar electricity at the full retail rate for Small PV systems (inverter capacity ≤ 10 kW-AC). As of June 2026, the residential retail rate in Albuquerque runs approximately 15–16 cents per kWh. That is a true 1:1 offset — one exported kWh erases one consumed kWh from your bill at the same price you would have paid for it.

Do unused PNM net metering credits expire?

No. Under PNM's Small PV Program, surplus kWh credits accumulate on your account as a "Cumulative Renewable Energy Credit" and roll forward indefinitely with no expiration date. They are only cashed out at the much-lower Rate 12 wholesale rate when you close your PNM account — which is one reason right-sizing your system matters.

Is there still a federal solar tax credit in 2026?

Not for homeowners who purchase or finance their own system. The 30% Residential Clean Energy Credit (Section 25D) expired December 31, 2025. The primary federal incentive that remains flows through third-party ownership structures (leases and PPAs) under the commercial Section 48E credit. New Mexico's 10% state credit — up to $6,000, refundable — is the main owner-purchaser incentive in 2026.

What happens to my net metering if I get a system over 10 kW?

Systems with inverter capacity above 10 kW-AC move from the Small PV Program to PNM's Large PV Program. Instead of rolling over as kWh credits at the retail rate, surplus generation is paid out monthly at PNM's Rate 12 — an avoided-cost or wholesale rate that is substantially lower than retail. For most residential applications, staying at or below the 10 kW-AC threshold is financially preferable.

Does net metering apply in Las Cruces and southern New Mexico?

No. Las Cruces and most of Doña Ana County are served by El Paso Electric, not PNM. El Paso Electric has its own net metering tariff with different rules and credit rates. This post covers PNM's program, which serves Albuquerque, Rio Rancho, Santa Fe, Corrales, Los Lunas, and most of northern and central New Mexico.
