I normally don’t make to many reviews, but Aaron and the team with Ecocentrix was amazing through the entire process and I have to share that. Everyone was very informative, knowledgeable, friendly, professional, and patient throughout the process. The process normally would have taken 3 months, but it took a bit more for me because a new roof was needed. Once that was installed the process to install the panels were pretty fast because they had already did their due diligence having everything in order before they installed everything.Anytime I had questions the team would always be there to answer those questions promptly. They also made sure I was always informed of what was going on and the next steps in the process as well. Keeping an open line of communication was very important to me as I was very new to this process and it made me very appreciate of that fact.The solar panels have worked wonders as well since they have been installed. We’ve seen a major decrease in the electric bill just as they said it would and it feels like a burden with the electric bill has been lifted. Thank you guys for what you do! I’d recommend everyone to ECOcentrix!

I spent so much time trying to decide on solar (way too many plans/systems and misinformation). My wife suggested we speak with Jonathan from ECOcentrix. She has a few friends who went through them for solar and had great things to say about them. I’m so glad we did! 5 star company, quality material, labor and excellent customer service. They truly believe in what they are doing and they work hard to be the best for their customers! I am confident this company will still be around years from now so my system is in great hands. Give them a call. I believe you will not be disappointed! Thank you Mollie, Aaron, Jonathan, Mike & Sarah.

Mollie and Aaron spoke with me at length about whether solar would be a good fit for my new home. They were thorough and honest, ultimately helping me to see that it’s not likely a good fit for my home at this time. They’re helping me to find an energy auditor instead, to see how we can improve our energy use. They genuinely care about their customers, speak to the client’s specific and individual situation rather than a universal sales pitch and were able to explain everything in great detail. Thank you Aaron and Mollie!

ECOcentrix did everything they promised and more. Our system is producing as planned and we can monitor it on our app. We have enough surplus to replace appliances with electric as they need replaced. Love it!!

Very knowledgeable about the industry. It is good to have someone who can help with filing all the applications and paperwork. Also they know of all available incentives to go solar. Check out their energy audit that is a part of their program. Very impressive component that other solar companies simply do not have.

This company is top notch. Great service from the start to finish of our solar job. The presentation was understandable and accurate to what we could expect. The plan for making our home more energy efficient was easy to do with Aaron and Molly’s help step by step. Streib electric assisted with the installation and were professional as well. Would definitely recommend this company for Energy solutions and solar. Very happy we met them at a home show.
