New Mexico Solar Incentives & Rebates Guide 2026

The federal Investment Tax Credit (ITC) allows New Mexico homeowners to deduct 30% of the total cost of a solar energy system from their federal income taxes. For a typical 6kW system costing $16,320 in New Mexico, that's a direct tax credit of $4,896. This isn't a deduction — it's a dollar-for-dollar reduction of your tax bill.

The 30% ITC is available through 2032 under the Inflation Reduction Act, then steps down to 26% in 2033 and 22% in 2034. There's no maximum cap on the residential credit. If your tax liability is less than the credit amount, you can roll the remaining credit forward to the next tax year. The system must be installed on your primary or secondary residence, and you must own it (leased systems don't qualify for the homeowner credit).

In addition to the federal ITC, New Mexico offers its own state solar tax credit: 30% of costs, up to $15,000 (10% solar tax credit per year for 10 years). This state credit can be claimed alongside the federal credit, stacking your total tax savings. For a 6kW system, the New Mexico state credit saves you approximately $15,000.

Combined with the federal ITC, your total tax credits amount to $19,896 — reducing your net system cost to just -$3,576. That's a 122% reduction from the gross cost.

Great news for New Mexico homeowners: Solar energy systems are exempt from property tax assessments. 100% property tax exemption Studies show solar adds 3-4% to home values. For a $300,000 home, that's roughly $12,000 in added value — and with New Mexico's property tax exemption, you save approximately $132 per year in property taxes you'd otherwise owe on that increased value.

New Mexico exempts solar energy equipment from state sales tax. On a 6kW system costing $16,320, this saves you approximately $1,061 at the point of purchase. This is an immediate, upfront savings that reduces your out-of-pocket cost before even accounting for tax credits.

Net metering policy: Full Retail Rate. Full retail rate net metering The current system size cap is 80 MW program cap.

New Mexico's full retail rate net metering is one of the strongest solar policies available. Every excess kWh your system sends to the grid earns you a credit at the full retail rate of 15.08¢/kWh. This means your solar panels generate maximum value — surplus energy produced during sunny hours offsets your evening and nighttime consumption at the same rate you'd pay to buy that electricity.

New Mexico has a mandatory Renewable Portfolio Standard (RPS) target of 50% by 2030, 80% by 2040, 100% clean by 2045. This legally binding target drives continued investment in renewable energy infrastructure and often supports solar-friendly policies like net metering and SREC programs. A strong RPS is generally good news for solar homeowners, as it creates market demand for renewable energy and helps maintain favorable solar policies.
