Commercial Solar Consulting in Illinois and Missouri

Solar Success Starts with the Right Partner

At EFS Energy, we believe that solar success isn’t just about panels and production, it’s about people. That’s why every project we take on starts with a conversation and a trusted consultant who understands your operation, your industry, and your goals.

Whether you’re running a family farm, overseeing a school’s budget, managing a car dealership, or operating a large-scale manufacturing facility, solar is a smart move. But it’s also a complex one. The good news? You don’t have to figure it out alone.

“They have a good labor force. They know their business.”

-Larry Hasheider, Owner, Elm Farms, Okawville, IL

What is a Solar Consultant?

An EFS solar consultant is more than a salesperson, they’re your expert guide through the solar process from start to finish. With a deep knowledge of utility programs, local regulations, available incentives, and system design, our consultants are here to help you make confident, informed decisions for you and your company.

The goal of each of our consultants is to work together to bring clarity, strategy, and a commitment to building a solar project that fits your space, your finances, and your long-term goals.

What Happens During Your Initial Consultation?

Your solar journey begins with a simple 30-minute consultation. Your EFS consultant will ask questions about your current energy usage, property setup, facility size, and what you want to accomplish. Whether you’re trying to reduce your utility bills, gain energy independence, or take advantage of solar incentives, we tailor the conversation to your needs.

You’ll learn about the process, the costs, the financial return, and most importantly, the possibilities. We know farmers want to increase profitability without increasing labor. We know business owners need reliable numbers and realistic timelines. And we know how to deliver both.

How Working with an EFS Consultant Pays Off

At EFS Energy, we’ve completed over 650 solar installations across the region and secured more than $13 million in incentives for our customers. Many of our clients have had their solar systems in place for over a decade and their systems are still producing energy levels that meet or exceed the original performance estimates.

Don’t just take our word for it. The results speak for thmselves:

Mike Auffenberg, Owner, Auffenberg Dealerships, O’Fallon, IL

$5.9M Incentives Secured

Mike leaned on EFS’s knowledge of Illinois incentive programs. As he puts it, “EFS had a good knowledge of how the Illinois program worked—how to submit it, how to follow up with it—everything we were concerned about. They did a good job the first time around and earned our trust.” His company’s year one incentives after switching to solar included a $1.8 million federal tax credit and $4.1 million in SREC payments from Illinois Shines.

Joe Barron, Owner, Barron Swim School and Barron Gymnastics, St. Louis, MO

$115,000 School Savings

Joe worked with EFS to install over 175 kW of rooftop solar on his two school sites. By leveraging Ameren MO’s net metering, Joe was able to drastically reduce one of his largest overhead costs. Since installation in 2019, his solar energy systems have saved his schools almost $115,000 in operating costs.
That kind of success doesn’t happen by accident. It happens when smart design, accurate forecasting, and honest communication come together. Which is exactly what you get with your EFS consultant and the entire EFS solar team.

$30K/Year Payback

Terry worked with EFS to save $30,000 annually between electric savings and selling excess power, with payback of his company’s installation costs in under three years.

Larry Hasheider, Owner, Elm Farms, Okawville, IL

Long-term Profits

Since 2018, Larry has installed over 1,200 solar panels and is continuing to see long-term profitability without adding labor.
