EFS Energy

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!

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.

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.

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.

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!

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!

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!
