EFS Energy are Illinois and Missouri Solar Panel Installation Experts.

We have had a negative electric bill for the past couple of months. Now that the heat has reached normal St. Louis temps, I assume our bill will break 0, but will still be half the price it was. Paul, the owner, is a dependable guy who is passionate about solar and is happy to take the time to explain all the details of your installation.

Paul McKnight and his team dud an excellent job putting up new solar panels on our roof, tube lights, and insulating our house crawl spaces. His crew were courteous and knowledgable, and always followed up! I would highly recommend EFS Energy to anyone!

Kenny is a knowledgable spokesman who lays out the facts and allows people to make decisions. He does not make a hard sell or push people; he explains the systems and patiently answers questions so people can make informed decisions.

Todd in sales was amazing! The install team of Rick and his crew were equally amazing. I highly recommend EFS and completed satisfied with our new solar system. Thank you EFS for everything!

EFS Energy was pleasure to work with on my solar project. They explained the technology and the limitations of my site. They assisted me in getting the necessary county permits and waivers. Their subcontractors were friendly and efficient. Their followup has been effective with only minor delays.

I had solar panels installed on my flat-roofed Saint Louis City home in August 2013. All of the contracting, licensing and permits were handled by Earth First and the installation was tidy, timely and professional.

EFS recently installed a 150 kWh on our building and we could not have asked for a better result. We began with just a basic knowledge of solar but they did a fantastic job guiding us through the entire project. Everyone we dealt with was knowledgable and very professional.
