When Is the Best Time to Go Solar in New Mexico?
New Mexico is one of the sunniest states in the country. With over 300 days of sunshine a year, it is no surprise that more homeowners are asking: when should I actually go solar? The short answer is that the best time is sooner rather than later — but the timing still matters. Read on to learn what affects the ideal installation window and how to make the most of available incentives.
New Mexico's Solar Potential: Why It Matters
The Land of Enchantment ranks among the top five states for solar energy potential in the U.S. Cities like Albuquerque, Las Cruces, and Santa Fe average between 5.5 and 6.5 peak sun hours per day. That means a properly sized solar system can offset a large portion — sometimes all — of a typical household's electricity bill. The sooner a system is installed, the sooner those savings start adding up.
Current Federal and State Incentives You Should Know About
Incentives are one of the biggest factors in timing your solar purchase. Here is what is available as of 2025:
Federal Solar Investment Tax Credit (ITC) The federal ITC currently allows homeowners to deduct 30% of the total cost of a residential solar installation from their federal taxes. This credit is locked in at 30% through 2032, then steps down. Installing now means capturing the full benefit.
New Mexico Solar Market Development Tax Credit New Mexico offers a state income tax credit of 10% of eligible costs, up to $6,000 per taxpayer per year. This credit is subject to an annual statewide cap, and credits have sold out in previous years. Applying early in the year improves your chances of securing your allocation.
Net Metering in New Mexico PNM, EPE, and other New Mexico utilities offer net metering programs, crediting customers for excess power sent back to the grid. Net metering rules can change over time, so locking in under current favorable terms is a reason many homeowners move quickly.
Property Tax Exemption New Mexico exempts the added home value from a solar installation from property tax assessments. This makes going solar a financially neutral move from a tax perspective on your home's assessed value.
Best Seasons to Install Solar in New Mexico
From a weather and logistics standpoint, spring and fall are generally the most practical times to schedule a residential installation:
- Spring (March–May): Mild temperatures make roof work comfortable. Installers are busy but not yet at peak summer demand. You will be generating peak power heading into the long, sunny summer months.
- Fall (September–November): Installer schedules sometimes open up after the summer rush. You can lock in incentives before year-end tax deadlines, which is critical if you want to claim credits on that calendar year's taxes.
- Summer: High sun production is great, but installer backlogs can push timelines out by weeks. Plan ahead if you want summer installation.
- Winter: Contrary to common belief, cold and clear days can actually be highly efficient for solar panels. Installer availability is often better, and you can still claim incentives before the tax deadline if you move early in the season.
How Long Does a New Mexico Solar Installation Take?
Understanding the timeline helps you plan around incentive deadlines:
- Site assessment and design: 1–2 weeks
- Permitting: 2–6 weeks depending on your county or municipality
- Installation: 1–3 days for most residential systems
- Utility interconnection approval: 2–8 weeks
Total timeline from signing a contract to turning the system on typically runs 8 to 16 weeks. If you want to claim the New Mexico state tax credit for a given tax year, you should start the process no later than September or October to allow for potential permitting delays.
Is Going Solar Right for Your Home?
Solar is not a one-size-fits-all solution. A few things to evaluate before committing:
- Roof condition and age: If your roof needs replacement in the next 5 years, handle that first.
- Shade and orientation: South-facing roofs with minimal shade perform best in New Mexico.
- Electricity usage: Higher monthly bills generally mean faster payback periods.
- Ownership vs. lease: Buying outright or financing provides access to tax credits; leasing typically does not.

FAQ: Going Solar in New Mexico
H3: Does New Mexico have a solar rebate in 2025?
New Mexico does not currently offer a direct utility rebate statewide, but the 10% New Mexico Solar Market Development Tax Credit acts similarly. Individual utilities may have their own programs — check with your provider directly.
H3: What is the payback period for solar in New Mexico?
Payback periods vary based on system size, energy usage, financing, and incentives claimed. Many New Mexico homeowners see payback estimates in the range of 6 to 10 years, but this varies — confirm projections with your installer using your actual utility bills.
H3: Can I go solar if I rent my home in New Mexico?
Generally, you need to own your home to install rooftop solar. Renters may have access to community solar programs. Ask your utility provider about community solar subscription options in your area.
H3: What happens to my solar system during New Mexico's monsoon season?
July and August bring monsoon rains to much of New Mexico. While overcast skies temporarily reduce output, modern panels are weatherproof and the impact on annual production is modest compared to the other 10 months of strong sunshine.
H3: Will net metering go away in New Mexico?
Net metering policies can change as utilities update their rate structures. Current programs remain in place, but locking in now means you may be grandfathered under more favorable terms. Confirm current policy with your utility before signing a contract.
The best time to go solar in New Mexico is when the incentives are strong, your home is ready, and you have enough lead time to meet your tax-year deadline. Right now, those boxes are checked.
