Top Ranked Companies


The Good

  • Industry Certifications
  • Production Warranty
  • Yearly Maintenance Package
  • Free Virtual Estimates
  • Company Longevity 
  • Hero Discount and Financials 

Industry Certifications

The company is certified by North American Board of Certifies Energy Practitioners and is a member of The Missouri Solar Energy Industry Association, The U.S. Green Building Council, and the Illinois Solar Energy Association. These certifications and affiliations signify a commitment to sustainability and good business practices. 

Production Warranty 

EFS Energy uses high-quality solar panels and inverters from reputable manufacturers, ensuring that customers get the most out of their solar systems. To that end, the company also offers a 15-year production warranty that ensures energy production is meeting all requirements of the state rebate program. 

Yearly Maintenance Package

EFS Energy provides its customers with yearly maintenance package including cleaning, a full system inspection, and detailed monitoring of the energy production. Note that the cost of maintenance is presumably not included in the price of a solar system installation. 

Free Virtual Estimates

EFS Energy has the technology to provide potential customers with free virtual estimates. This is helpful for clients that don’t do well face-to-face with salespeople. Some feel anxious and appreciate the initial estimate to be done virtually without any pressure. 

Company Longevity 

EFS Energy has great processes using the latest technology to accurately give customers data about their property with options for design and solar installations. Its processes in shade analysis over time have proven to accurately assess what customers need to have the energy production they want.

Time in business is always an asset, giving customers peace of mind that the company will be around to help if problems come up.  EFS Energy has been in the solar industry for over a decade and has installed more than 2,000 solar systems. The team includes engineers, electricians, and project managers who are knowledgeable about all aspects of solar installation.

Hero Discount and Financials

EFS Energy offers a discount to heroes in our communities who are often underpaid and may not have the financial resources available to go solar.  The discount applies to the following jobs: 

  • Active military
  • Veterans
  • First Responders
  • Educators

Qualified customers need to speak to a customer service representative for specific information about the offered discount.

While the company does not make specific pricing and payment information readily available until you schedule a consultation, it does say it helps customers with financing options and incentives to help make solar more affordable.

EFS Energy wants clients to benefit from incentives that help reduce the overall out-of-pocket cost. If a customer signs up for a program and doesn't receive the financial break due to a production shortage, the company wants to make things right.


The Bad

  • Needs Customer Reviews
  • Limited Service Area
  • More Information Needed 

Needs Customer Reviews

While EFS seems like a good solar company, we can’t definitively recommend it without verified reviews from customers. Prospective customers can read reviews to determine if a company and its representatives are knowledgeable, highly trained, honest, straightforward, professional, and friendly. 

If EFS has done a solar project for you, please leave a review below! 

Limited Service Area

EFS Energy only provides service in the Midwest states. The company doesn’t disclose information about any jobs outside of Missouri and Illinois where it has completed work, so further research may be needed to identify specific availability. 

More Information Needed

While EFS Energy's website provides basic information about its services and experience, it does not offer detailed pricing information. 

Most solar companies don’t give pricing online due to the nature of the services. Many factors play into what a panel system will cost, so EFS Energy needs to do a virtual quote to give a price. 

Additionally, the website does not provide detailed information on the warranties offered by EFS Energy, which could be a concern for potential customers who want to ensure they are protected in case of equipment failure or other issues.


The Bottom Line

EFS Energy has a lot of boxes checked and seems like a good option for solar installation if you live in the Midwest. It has been in the business for a decade and has a great visual Rolodex of its projects online for potential customers. 

EFS Energy is local and claims to have excellent customer service, offering its customers yearly visits to make sure energy production is at its peak performance and clients are still happy. 

As always, we suggest getting a few quotes when looking for a solar company and having hard copies to compare products used and pricing.
