Residential Solar Power

EFS Energy strives to be the leading residential solar power installation and design firm in the Midwest by providing the most advanced and cost-effective solar energy solutions. Installing solar panels on your home turns simple sunlight into usable power, and in turn boosts the value of your home, helps you become more energy independent, and saves you money.

When it comes to your solar system, we will take a customized approach to meet your specific energy needs. We will make sure you are pleased with your system in every way possible and strive to always put the Earth First in Solar.

We work hard to implement the newest and best option of this cutting-edge technology to give you the best system that you can get while providing high-quality home solar panel installation! Ask us about our favored and recommended products including SolarWorld panels and SolarEdge DC Optimizers.
Although we perform any work with the highest possible quality and attention, we do offer a 5-year service warranty that includes any issues that arise with the electrical or wiring work, roofing problems related to the job, monitoring system issues, or any equipment failures.
Solar energy is a solid financial investment in your own property. You can think of it as an alternative to investing in the power company, and this way you are no longer susceptible to rate increases over the next 25 years (which is how long our systems are warrantied for).
Markets across the U.S. have noted solar energy installation can add 50% to the property’s value so you know you’re making a solid investment. Also, according to the U.S. Department of Housing and Urban Development, home values rise an average of $20 for every $1 reduction in annual utility bills!

“All work was done as planned and the overall solar production came out very close to what was estimated. I am very pleased.” –Jeanne, Chesterfield, MO

“After more than 3 years working to find a company to step up to the complete job of building a solar pergola/carport with electric car charger, after false starts with other companies, EFS was the one that was able to undertake and follow through with every aspect, even with the added complications of working in an historic district. Not only am I highly satisfied that the results matched what was envisioned, and completely within budget, but I have been pleasantly surprised by the many positive comments and compliments from neighbors.” –Guy, St. Louis, MO
