From start to finish... this team was amazing. We researched solar on and off for 6+ years. We strive to support local and just felt the nationwide companies were not a fit for us. Ilumen fit the bill on so many levels. Local Illinois company with a big company feel and capabilities. They answered countless questions and walked us through every detail to get our unique system reviewed by the local municipality, installed and ultimately approved for final inspection. Our house was heavily shaded by substantial oak and hickory trees. However, Ilumen didn't panic when we approached them about putting the system on our outbuilding and back-feeding to the house. Every other company wanted to trench up our yard or told us it wasn't possible. Ilumen went out of their way to meet our needs and provide a system that worked within our budget and our unique physical setup. We're just a few months in but have seen the system out perform their original projected productions.

Thanks for the wonderful review Kellie! It was great working with you and Jeff on this project and we're glad everything worked out as expected! Not every install is straightforward, so we had to think outside on the box on this one : ) If you ever need anything, you know where to find us!

Illumen installed an expansion to my solar panels, an integrated Franklin battery system and two EV charging stations. The Franklin a-gates are performing perfectly and the system is well balanced between supply and demand across two separate subpanels. So far, I have not received a bill from ComEd since July as the solar power and batteries typically cover all of my electricity needs per day. I presume that is because my bill was NEGATIVE!! Also, we had a power outage a few weeks back and the system kicked in to take over perfectly. All of this would not be possible without Ilumen’s excellent guidance and execution on my project. This is the kind of company you can trust to build a solid, cost effective solar system.

Bryan, thank you so much for the kind words, and it was great working with you throughout the year. This project was an interesting one! We started off with a roof replacement solar removal and reinstall, then added double the solar capacity, then added in a robust Franklin Energy System, and critter guards. No outage or squirrels will stop you now! We're so glad everything turned out great and happy to hear the news about your ComEd bills and the batteries working as expected! If you need anything, you know where to find us!

ilumen Solar did an outstanding job from the from start to finish. Our house had many challenges, but we worked together to find a good solution. They were easy to work with, always quick to respond to any questions and we love being on solar! I did get quotes from other providers and no one could match the quality and price that ilumen brought to the table. I would highly recommend you use ilumen.

My solar power panels were down due to squirrel wanting it for their winter/summer home under my panels and to chew up my wires. My original solar company went out of business over 18 months ago. After many, many phone calls and false promises. I had pretty much given up hope of fixing my system, 15 companies overall . Ilumen Solar [number 16] was the only ones willing to take action and fix what needed to be fix and upgraded any issues (CRITTER NETTING) .The installers sent out were top notch and got the job done AND we both learned that squirrels are quite resourceful on setting up house THE BOTTOM LINE is that your company helped me out to get back on line so THANK YOU ALL!! John

Zach and the team at ilumen share a passion for solar. Each person we spoke with was knowledgeable, diligent, and helpful. Ilumen Solar provides a top-quality product for a reasonable price. They walked us through every part of the process and patiently answered any of our questions. We feel confident the solar panels were installed properly, and they monitor the entire system remotely, so I don't even need to think about it. It is time to enjoy the savings on my electric bill and gain peace of mind that we are helping the environment for our kids. Would definitely do business with ilumen again and highly recommend them to anyone.

Unfortunately the solar industry is full of scams and fly-by-night installers. It was actually quite difficult finding someone I felt comfortable enough with to do my install, and am very happy to have found iLumen. They were extremely communicative, thorough, up-front, honest, and completed a great install. And because my install was on new construction, the timelines get messy but they were always there when needed. After completion of the install I had a good laugh when I got a call ComEd asking why our meter was running backwards and if we had installed solar. Guess the system works!

It was great partnering with you on this project, so thank you for the business! Yes, unfortunately our industry can be challenging to navigate with correct information and finding a true partner for the install and beyond. Regardless of the delays, we all had a lot of fun and the install turned out great!

I got a referral for Ilumen Solar from the contractor that was doing some renovation work for me on the interior of my home. The contractor was very passionate about how good these guys are. Ilumen Solar just completed the install of my Solar System and let me tell you, they absolutely delivered! From start to finish, the process was professional, and efficient. Working with Zach, Dan and the rest of the team was truly a pleasure. They kept me informed at each stage of the project and very thoroughly explained each step through completion and beyond. They patiently and thoroughly answered the countless questions I threw at them and even took care of submissions for some of the rebates I qualified for. I am absolutely delighted with the experience I had with Ilumen Solar and I encourage anyone considering installing Solar on their home to give these guys your business. Your experience will be a fantastic one !

The feeling is mutual Kurt! It was fun working on this together. We're excited to have you as a customer, and looking forward to supporting you and the system for many years to come.

ilumen Consulting Approved Vendor services was able to secure a little over $600k in Illinois SREC and rebate funds for two of our commercial projects that were left behind by our previous installer. We were in a tough spot, and we’re thankful Dan and the team were able to come through in submitting our incentive application to secure our previously promised funds. If any project owners are in a tough spot and need assistance, you’d be in good hands here

ilumen installed my second solar system (I wish I had used them for the first one as well). Everything about their work was great. Zach is very experienced and knowledgeable, their whole team was polite and very quick with clear communication, and the price was competitive. I hope they stick around a long time because they do work that's far better than other companies I've worked with.

We recently finished working with Ilumen Solar for our company's solar installation, and their patience & professionalism throughout the entire process was the highlight of their customer service. What began as a typical project turned into a long journey due to unforeseen delays (specifically with Com-ED), and construction upgrades on our end. Despite the drawn out timeline, Zach & Dan at Ilumen Solar remained patient, understanding, and committed to our project. From the very beginning, the team worked closely with us, providing updates, answering every question we had especially helpful as a newbie to solar. Their customer service truly stood out when we had to deal with roofing inspections/roofing warranties where they went above and beyond to make sure things went smoothly with the roofers. The only thing we would warn to someone looking to install solar is the additional cost associated with maintaining roofing warranties. There was a mix-up with the Elk Gove Village inspection but Ilumen quickly corrected the issue which was just another example of quality customer service. The final solar layout on our roof is fantastic, and we’re already seeing the great positive impact of the solar panels on our energy costs without even a full winter month of generating. Would highly recommend Ilumen Solar to anyone looking for a solar energy provider. Their patience, expertise, and constant support throughout our project were invaluable.

Ilumen was great to work with. They spent time answering all my questions about the process and design. Care was spent to let me know ahead of time typical issues that come with install and permits. They also worked quickly on paperwork and installation. The system has been up and running for a few months now with no issues and a lower ComEd bill.

We were impressed by the professionalism and transparency of Zach's team throughout our residential solar installation last year. The project involved more complexities than we initially anticipated, requiring us to gain a deeper understanding of various aspects before signing off and during the execution. Zach, Dan, Dilip, and the entire team consistently provided excellent support and guidance, ensuring the project stayed on track. The system was successfully turned on November of last year and it has been fun to observe the production of green energy, even during the shorter days. While the process had its complexities, the team's personalized attention and clear explanations made it much more manageable. We truly appreciate the team's dedication to educating and informing their customers every step of the way. We highly recommend iLumen to anyone considering solar.

This individual called our business out of the blue stating he owned a solar business in Maryland and had 50 commercial projects ready to sign, which is unrealistic considering he needed help designing and pricing them out. He became combative, rude, and disruptive on the call, so we got off the line. Unfortunately, Khaleel did the same thing with several installers in the area, posting 1 star reviews as well.

Ilumen installed a new solar system (16.8 kW system) at my home. It started with an initial analysis by Zach. He did a great job describing the benefits of solar and designing a system for my home. Zach is a straightforward, honest and proactive professional. Unlike other less reputable providers, he didn’t try to talk me into decisions that were not economical or in my best interest. Zach’s integrity demonstrated throughout the quote process was what led me to hire Ilumen to design and build my system. He and his team (Dilip and Dan) were great throughout the execution of the project. They openly and frequently communicated progress, what was needed from me (home access, signatures for permits, input into decisions, etc.). They also were great at educating me about solar, my system, and how it all works. I also appreciated Zach’s choice of system installer. They were very professional and thorough as well. I would certainly hire Zach and his team at Ilumen again and recommend them to others. Zach, Dan and Dilip - thanks again for all of your hard work!

Zach, Dan, and the whole ilumen team were excellent. They went above and beyond to ensure our transition to solar went smoothly and kept us informed with what to expect every step of the way, and the system they installed outperforms the expected results. Very satisfied.

We had wanted to go solar for years. The main stumbling was the long ROI. Even though we plan to stay a long time in this house, 12 year ROI seemed to big of a stretch. Ilumen Solar was able to show an ROI in less than half that time. Zach, Dan and the rest of the team are a pleasure to work with. They really enjoy what they do and it shows in the results. They kept me informed every step of the project. The installation is clean and solid.
