Going solar in New Mexico now averages about $3.84 per watt. That means you can expect to pay roughly $3,842 per kilowatt (kW) of installed capacity before incentives. For example, a 5 kW system typically costs around $19,350 before applying the 30% federal tax credit. Once you factor in that tax credit, the out-of-pocket cost for a 5 kW installation comes to about $13,545

However, a 5 kW system isn’t necessarily the best size for homeowners in New Mexico. According to our data, New Mexico residents currently pay an average of 14.67¢ per kWh, with a typical electric bill of around $92.66 per month for 632 kWh of consumption. Considering this energy usage, a 5 kW system is ideal to cover the energy needs of most.

How long does it take to see a return on your investment in New Mexico?

The upfront cost is what you pay for a system (whether you pay cash or finance doesn’t factor in this equation). The payback period is the amount of time until you break even on your investment considering savings from energy bills. And the net 20-year savings is what you save over 20 years minus the upfront costs. All of these work together to show how much you could save with solar in the state.

5 kWh System	New Mexico Average	U.S. Average
Upfront Cost	$13,545	$12,530
Payback period	12 Years	7 Years
Net 20-year savings	$8,696	$22,173

How to pay for solar panels in New Mexico

Purchasing solar panels is no small task. Here are a few ways you can pay for solar:

Cash purchase: This is the best choice if you can afford it. Paying in cash gives you the best long-term savings but requires a larger upfront investment, of course.
Solar loans: You can spread the cost over time with a loan, but be mindful of interest rates and loan terms.
Solar leases and PPAs: Power purchase agreements (PPA) and leases have lower upfront costs. However, you don't own the system, which means you save the least over time. There can also be complications if you want to sell your home.

What affects the cost of solar panels in New Mexico?

Several factors impact the final price of your solar installation:

System size: Larger systems cost more upfront but often yield greater long-term savings.
Panel type and efficiency: Monocrystalline panels are generally more efficient and expensive than polycrystalline or thin-film options.
Installation complexity: Roof type, shading, and site-specific challenges can increase installation costs. Permitting and inspection fees also factor in.
Additional considerations: Battery storage adds to the initial investment but provides backup power and greater energy independence. Labor and installation quality are also essential cost considerations.

How to save on New Mexico solar panel costs

Getting the most bang for your buck is essential when investing in solar. Here are some strategies to save money:

Maximize the federal tax credit: Understand the eligibility requirements and claim the full 30% credit.
Shop around for quotes: Get quotes from multiple installers to compare pricing and services. Don't just focus on the lowest price; consider reputation, experience, and warranty.
Consider system size: Be careful of going overboard. A properly sized system will meet your energy needs without unnecessary costs. Analyze your energy usage to determine the optimal size.
Explore financing options: Compare loan interest rates and terms carefully. If considering a lease or PPA, understand the long-term implications and potential trade-offs. Cash purchases often offer the best long-term savings.
Negotiate with installers: Don't be afraid to negotiate on price. Inquire about any discounts or promotions they may offer.
Optimize your home's energy efficiency: Before going solar, improve your home's energy efficiency. This will reduce your overall energy consumption and potentially allow you to install a smaller, less expensive solar system. Simple steps like sealing air leaks and upgrading appliances can make a difference.
DIY (if possible and permitted): While professional installation is generally recommended, some homeowners may be able to handle certain tasks themselves (like site preparation). Check your local regulations and be honest about your abilities.
Ask about rebates and incentives: Many states, cities, and utility companies offer rebates, net metering, and other incentives. Check with your local utility and city/county for any available programs.
Time your installation: Sometimes, installers offer discounts during slower periods. Inquiring about seasonal promotions might yield savings.
