Electrical reviews in St. Louis, Missouri

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.

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!

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.

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!

EFS Energy installed my residential solar array several years ago (2014), and recently (Spring 2018) they expanded the array by a few panels. In both projects, the project planners were very knowledgeable and technically savvy, and the installers have been very competent. So far, I've been very pleased with the consistent, reliable performance of the array. I'm also pleased with the response by EFS to issues that came up during installation and to any questions I've had after project completion, especially about array performance and maintenance.

My only disappointment was in how fast the expansion project was completed. It took longer than expected to get permits approved, equipment ordered, and weather to cooperate, so I recommend scaling your expectations on timeliness, keeping in mind that demand for their services sometimes exceeds their capacity. In their defense, they typically work projects much larger than my recent expansion, and I'm grateful they made an exception to accept my modest project.

Solar energy projects are long-term investments, so I suggest to those in the market for solar energy installations to shop wisely, considering not only the installer's reputation but also their staying power. That said, based on my two experiences, I recommend EFS Energy without hesitation as a company with staying power, committed to the long-term sustainable success of solar and alternative power for residential and commercial customers.

Choosing EFS Energy for my solar installation was a good decision. They were recommended by a friend who also chose EFS for solar as well as a couple of other friends. The entire process was smooth and professional, from sales, through design, installation and production. I am very happy to be producing my own energy!

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.

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.

An update after 4 years: Very happy. I have not been able to add more panels -- the cost of boosting capacity by about 25% would be about 50% of the original cost! Wish I'd asked for more originally. But everything else has run very smoothly. Pay-off time for the array looks to be about 18 years.

------------------------------------------------------------------------------------------

Two years out from installation. Pretty happy overall. EFS was very good answering all my early questions. Installation was smooth and pretty close to their original estimate on timing. The system is now working well, and the few times early on when we had issues EFS was quick to solve them.

There were a few unexpected issues, just communication-based, nothing of substance. Production was a bit lower than I expected, and when I asked about it, EFS showed me the "shade analysis" that was probably in the documents they gave me after we were all done, but which had not come up in the planning stages. It showed that shading would reduce production by 4-28% (depending on month and array) from the values shown in the initial quote. I don't think that would have changed anything if I'd known in advance, but would have been nice to see.

The panels sit at a pretty low angle on our flat roof, 10 to 15 deg below optimal, and are not adjustable. I did not anticipate that, but this turns out to be standard for flat roofs so it is not an issue with EFS.

There are complexities with matching panel output with inverter capacity that I did not initially appreciate. There are graphs on the web (which EFS referred me to) that try to explain this, but they are not particularly informative. The real issue is that inverter capacity is cheaper than panel capacity, and given that you only generate peak panel power for a few hours (around noon) and for a few months (around the summer solstice), it is cheaper (capital cost per watt-hour) to buy panels rated for higher power than your inverter. Again, not an EFS issue, though a last--minute change really confused me for a while.

I'm actually hoping to add more panels to the system. With an electric car we are using more than we expected. We will use them again, if they respond to my email!

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!

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!

EFS recently installed a 150 kWh system 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 knowledgeable and very professional.

Thank you for doing such a great job! It was a pleasure working with you all.

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 can't say enough about how exceptional our experience was with EFS Energy! I'm a retired Boeing engineer and I researched and followed this process very closely. The first meeting with Kenny impressed us due to his technical knowledge of the system as well as the business aspects. Rick maintained the same level of professionalism during the installation process. The electricians that they used did a remarkable job during the installation and you have to look closely to find the internal wiring in our home. Finally, we met the owner and his attention to detail was more than we expected and he clearly wanted to have satisfied customers and he takes great pride in his company and his work. We would highly recommend this company to anyone!

Fun job

Nice friendly people

Great place to load, appt was 10am, loaded by 11am.

Super friendly and accommodating staff, especially Laura in shipping. Got me loaded in less than 20 minutes. Loves shippers like this.

It was a pleasure doing business with M-Co Wiring.

Horrendous experience. Do NOT recommend.

Excellent customer service and workmanship!
