Top Ranked Companies


The Good

  • Warranty Transparency
  • $0 Down Loan Financing
  • NABCEP Certified
  • Energy Industry Experience

Warranty Transparency

On its website, Aztec Renewable Energy clearly outlines the warranties it offers. It distinguishes between labor warranties, performance guarantee, and equipment warranties. This is important because many companies will claim their solar system has a 25-year warranty, when the equipment is only covered by a much smaller warranty. 

Aztec Renewable Energy is very transparent about each type of warranty:

  • 10-year equipment warranty — This warranty covers any faulty parts of the system for the first ten years after installation. 
  • 25-year panel performance guarantee — When a solar company initially quotes a system, they will estimate how much energy can be saved by installing the system. If the installed system stops performing at this expectation within the first 25 years of installation, Aztec Renewable Energy will repair the system so that it guarantees the same level of performance as it did at initial installation. 
  • 5-year labor warranty — If any part of the solar installation wasn’t done properly, this is covered by the labor warranty for up to five years after installation.

Loan Financing

While Aztec Renewable Energy only provides financing in the form of loans, the company’s website also provides a rationale for why it does not offer leasing options. With Aztec Renewable Energy loan financing, customers can get instant loan approval. 

These loans have varying terms, depending on the desires of the customer. At most, the company can provide $0 down financing with a loan up to $65,000 on a 20-year term. However, this is not the only option. Aztec Renewable Energy can issue loans at much shorter terms as well.

NABCEP Certified

Aztec Renewable Energy is certified by the North American Board of Certified Energy Practitioners (NABCEP), which sets it apart from other solar installers. All solar contractors should have electrical contracting licenses. However, the most reputable companies have the added certification from the NABCEP. To be considered NABCEP certified, a company needs at least one staff member with this certification. 

The NABCEP educates its certified members on the best, most current practices when it comes to solar installation. It helps its members stay up to date on industry trends and technological advancements so that they can provide the very best service to customers. Customers of Aztec Renewable energy can find comfort in knowing that the company is backed by this strong credential. 

Energy Industry Experience

Aztec Renewable Energy does not only do solar installation. It also helps customers conserve energy with wind powered turbine systems. Since the company president has been heavily involved in the industry for over twenty years, Aztec Renewable Energy has worked with many cities and power providers within its service area. The company has been in the industry a long time — the Aztec Renewable Energy team is aware of many solar company scams and tactics. With this knowledge, the company can more adequately describe what sets it apart from other companies in the industry. 


The Bad

  • Equipment Manufacturers Unknown
  • Limited Service Area
  • Few Customer Reviews

Equipment Manufacturers Unknown

It is unclear where Aztec Renewable Energy gets its solar equipment — whether it gets panels and inverters from an outside manufacturer, or the company manufacturers its own products. This information makes it a bit easier for customers to understand the quality of panels they are getting. 

However, the company does have a statement on its website that it does not purchase from low quality panel distributors that sell to unlicensed installers. Names or brands of these manufacturers are not stated. 

Limited Service Area

Aztec Renewable Energy primarily installs solar panels in Texas, but has also done a lot of work in Oklahoma. However, the company’s reach does not go beyond these two states. Customers located outside of Texas or Oklahoma will need to choose a different solar provider. 

Few Customer Reviews

While the company has been in business since 2006, Aztec Renewable Energy does not have many online customer reviews. The reviews that exist are generally quite positive, but there are very few of them. This would be more typical of a company that has only been around for a short time. But for a company that supposedly has a very strong reputation, we would expect to see more customer reviews. 


The Bottom Line

We recommend Aztec Renewable Energy to residents of Texas and Oklahoma, because this company is an industry leader for this geographic area. The Aztec Renewable Energy team has years of experience working with cities and power companies to make solar installations happen. Overall, the company is pretty transparent about what it offers and provides educational information about solar installations on its website.
