EFS Energy, St. Louis MO

Our ground built solar system was commissioned on March 29,2022 and has worked less than 6 weeks consecutively. Yes, you read that correctly. EFS HAS been out to our home many times and every time they leave it is not fixed. Many times a different problem exists. It is beyond frustrating to not only have an electric bill but a solar loan as well with no plan or end on sight.
If this nightmare ever ends we will update this review for future reference.
Update: 6/2023 for just over 1 month we have had working solar! Let me give you a short story of how we got here. When the initial electrical was put in for the solar to house they did not catch that the wire going from the house back to our electrical box was too small for the current. Sooo, we had to pay for that upgrade 3,000. Now all is working fine. So all I have to say is read your contracts really carefully.

No one in the company has a electrical license might as well just watch utube like they do no business license all year of 2022 and all the old good reviews all those people have been ran off better off just calling steib that who they would have to sub out to anyway if electrical license needed and efs warranty won't matter they will be bank rupt soon

I worked with EFS Energy in getting solar panels for our home. Tawn, my sales rep, was very easy to talk to, knowledgeable, and professional. Among the 3 companies I got quotes from, EFS energy was the most competitively priced, had the best reviews, and seemed to have the best product.

It was a lengthier process than I expected. I started the process (LOI) in mid-October and finally got them installed end of February, and the final closeout mid-April. While Tawn was great to work with, I wish there was someone that kept me more updated throughout the design/installation/post-installation process. I reached out to a project manager several times for an issue that came up after installation, and for updates post installation - although they did get back to me quickly.

All in all, I highly recommend this company to anyone considering getting solar panels!

Working with EFS to get solar installed has been a challenge. They are highly rated, competitively priced, and I believe this equipment is quality and expect it to perform well. That being said, the process to get the location of the array, permitting, inspection, and installation was not managed particularly smoothly at all. I had to call frequently throughout the process to follow up on things they said they would do. Often times it seemed as though the different departments within the company were not communicating or aware of what the other had done or were supposed to do. After I signed the initial contract, I referred them to my father, who paid a deposit, but my father rescinded the deal because he found that he was misled in regard to permitting being submitted. He was told it had been done, and it had not. The accounting department asked me for payment in full before installation had even taken place. Once installation was complete, I was sent a final invoice, and paid it. Only for them to come to me later to say that they had missed a payment and my commitment was not completed. From signing the contract in May, it took nearly 7 months to get the system installed and approved and actually generating energy. I chose them because of their high customer service and competitive pricing; however, I did not receive a very high level of service. If you decide to go with EFS for your solar, be prepared to be actively pursuing them to do the work that they say, in a timely manner, with proper local approval. Again, I do expect the system itself to be quality and a valuable asset to my home but getting to the finish line was rough.

System is over seven months old and not working properly. They come out, and still not working properly. Then they don't show up for months.

They chase you to get the contract and pay $2000 for a non-refundable deposit and sign an LOI. After I paid the deposit and they did a site visit, I did not hear from anyone and there was absolutely no communication. After I ended up getting a hold of them, they said the agreed price would most likely increase. I tried to get my $2000 deposit back and I had to chase them and even spoke with the owner. They refused to refund the deposit because it was apparently “non-refundable”. Please BEWARE.

We had our system installed three years ago and what I appreciate the most is that their projections were practically spot on. I expected a vast oversell, but they were on the money.

About 18 months in, our inverter died. I didn’t catch that until a couple of weeks later, but as I called in, they said the part had arrived. Next day, they swapped it out, no hassle, no charge (warranty). Their monitors had caught the problem and ordered a replacement on my behalf. Nice!

I had a great experience with Jeremy from EFS Energy from the start. He made sure he answered all of my questions and made sure I knew what was going on as much as possible.

The installation team was top notch and did a fantastic job putting everything up onto the roof and installing all the electrical. It was a very professional job and looks very good.

After the system was fired up I noticed that it wasn't producing what I had been told. I called EFS and they came out to assess the problem. Turns out during a county inspection, a connector had been disconnected. We were back up and running in no time.

My only complain was a scheduling error that required me to take extra time off of work. The owner apologized for the error and said they would make changes so this wouldn't happen again.

I'm happy about the 10 year warranty and top notch service they provide. I would recommend EFS to anyone looking to get solar.

New solar customers here! Interviewed several solar installation companies and went with EFS Solar in St Louis. We liked the idea of going with a local company, and EFS fit that requirement, answering all our questions and concerns. Justin Evans and Janet Hazel were our primary contacts into the solar world, and they took the time to educate us on the benefits, limitations, and overall costs of having a solar power system installed on our home. Justin and Janet stayed with us throughout the engineering, construction and commissioning phases ensuring all paperwork, permits, and scheduling was done timely and accurately, coordinating the many facets of having a system installed and setting realistic expectations for completion. The overall process took several months due to all the moving parts, but the EFS Team was in constant contact with us via email, phone, or video calls. The construction team was very professional and knowledgeable and did their part well. The electricians did a phenomenal job installing the peripheral equipment and wiring required. The overall install easily passed local building and fire code inspections. Lastly, Enrique arrived on-site to do a final commissioning inspection and to ensure our operational questions were answered prior to turning the system on. Overall great experience and we highly recommend EFS Solar!

It has been 3 years since our solar system installation by EFS Energy and I just wanted to share our experience with the installation and with the subsequent electric production. The process went very well from bid to final install. The crew was professional, efficient and the quality of work was excellent. Our production since install has been pretty darn close to projections and I am really pleased and happy we made the investment. It's obviously a longer-term payback but I'm OK with that. And the feeling of environmental contribution and general peace of mind I get every time I I look at the panels in immeasurable. I highly recommend EFS Energy for any solar project you are considering.

We placed Solar on our Barn this summer and have not paid a penny to the Electric company since! EFS was wonderful to work with. Paul is fantastic! Highly recommend them!

EFS installed a solar system for us in 2019. The roof began leaking in March of 2021 and it took over ten phone calls to get the leaks and subsequent damage repaired.

During this process it was discovered that EFS had reduced my plumbing vent and radon vent pipes from 3" to 2" and I confirmed with the local plans examiner that this was in violation of residential building codes. I have been in contact with the owner of EFS Paul McKnight and he committed he would have the problem corrected. Over twelve weeks later nothing has been fixed and no one is returning my phone calls.

Although EFS places a 10 year warranty for their work in the contract, they do not back up that warranty with action. I have been forced to file complaints with the BBB and attorney general in order to seek relief and I cannot recommend anyone do business with this company.

A special Thanks to Todd and everyone involved with our 14kW residential solar install. They did a fantastic job, even during this difficult time. I will gladly recommend EFS to anyone!

Austin introduced us to our solar panel plans. Very friendly & easy to work with. He listened to our idea for solar panels, work up a doable plan & presented it to us. He listened to a couple ideas we had, tweeked the plan a bit and it worked out perfectly.
The installers did a great job installing our panels on our garage roof. Electricians did a great job also. We are very happy & excited about having solar & doing a small part of going green!
EFS is highly recommended by us!
Bring on the Sunshine!

My entire experience with EFS Energy has been nothing short of spectacular. My Energy Consultant, Austin Richards, walked me through the entire process and answered every single question I had. It was really cool to see the computer software show an overlay of my roof and calculate the energy production of each individual solar panel to maximize the efficiency for my specific property. The solar panel installers had all 23 solar panels up in a single day. They were immediately followed by Jeremy Weeke and his crew from Weeke Sales and Service who are true craftsman in their trade and made all the electrical connections neat and clean. Once Ameren approved everything, my solar panels were switched on and I am now up and running. This has been a lifelong goal of mine and this process was so simple and easy for me and was better than I could have dreamed for.

Our experience with EFS was fantastic! Austin was so helpful and answered all of my questions along the way (I had a lot!). The process was painless because EFS took care of everything. LOVE our panels and love EFS.
