  Showed up right on time for an inverter replacement, had it replaced quickly. Quick responses to emails too.

  Ilumen Solar was incredibly helpful and responsive in getting my SREC application completed after I was left stranded by my original solar contractor. They knew exactly what needed to be done and quickly helped resolve the problem. I would highly recommend Ilumen Solar to any stranded solar customer.

  There was a panel in my array that was only producing about half of the other ones. After getting the run around from the company that installed the system, I decided to contact Ilumen Solar based on their reviews. Best decision I made regarding my system. Even though the original panel was supposed to be replaced under warranty, Ilumen only charged an addition $50 to purchase and install a new panel. Two days later, instead of weeks of excuses, the panel was replaced and my system is at full power. I never have to worry about getting service again. Ilumen is my new go to solar company.

  This review is long overdue! When we bought our home in 2021, we knew we wanted to go solar. Out of all the installers we contacted, Zach was the only one who didn't sound like a typical salesperson. His genuine passion for the industry is what ultimately sold us on the project. While the process took some time to get off the ground due to HOA/ Developer approvals, Zach and his team were incredibly communicative and supportive throughout the delays. The actual installation in 2023 went exactly according to plan. The entire installation team did a fantastic job keeping it clean with minimal visible exterior conduit. Our solar production over the last 2 years has consistently performed the initial estimates. I highly recommend Zach and his team for an honest, high-quality installation.

  Scheduling stayed organized the entire time, which honestly surprised me. Every appointment happened close to schedule and updates were consistent. The lower electric bill has been a huge bonus already.

  I'm very happy with Ilumen. They fixed my system when no one else would support my hardware. They were responsive and got the job done quick. I wish I had found them sooner.

  Really happy we went with them!! Everyone we worked with was kind, respectful, and easy to talk to. They answered any questions, explained things clearly, and never made the process feel overwhelming. The install this past week went smoothly and the crew took great care of our home. Overall it was just a really positive experience and we’d definitely recommend them to anyone considering solar!! 🩵

  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.

FREQUENTLY ASKED QUESTIONS

Residential installations typically take about 8-10 weeks, from signature to flipping the switch. The physical installation could take anywhere from 1-3 days depending on they system size.
Overall, there is minimal maintenance required for solar panels - just set it and forget it! If an unusual occurrence is noticed with your system we will quickly investigate and/or send out a technician in a timely manner.
Panel soiling does happen with dust and pollen collecting on the panels; however, mother nature tends to take care of this with occasional rain showers. All in all, we factor in system losses due to weather and soiling in our production tool to accurately map real world system performance.
Typically, if a roof is greater than 10 years old we recommend having it inspected and/or replaced prior to installing solar. We are happy to assist with this process, as we work with many trusted roofing companies.
In the winter your solar system still produces energy, just not as much due to the sun being lower in the sky. We do not recommend any clients attempt to clear snow off the panels.
A south facing roof in the northern hemisphere is the perfect scenario to receive the most solar irradiance. However, many east and west facing roofs without other shading factors will still produce enough irradiance to make solar a great fit. If you have a lower slope east/west roof, then you should yield fantastic solar production.
Properties with significant shade are usually not the best fit for solar. The panels will still produce energy, just at a lower rate, meaning a longer return on investment. However, trimming trees can drastically increase solar production. If you are curious on how shade impacts your particular situation, please reach out and we will take a look!
net metering is a solar crediting program run through your electrical utility. In this program, you gain credits on your utility bill when your system out-produces what you consume and sends kilowatt-hours (kWh) back to the grid. When your system produces this excess energy (typically in the summer), credits are stored and can be used to offset your bill in lower solar-production months (typically winter).
Solar systems do not come with batteries, but they can be added for an additional investment. Batteries offer the added benefit of resiliency during power outages. We offer a wide variety of battery solutions, so feel free to reach out with questions!
In most cases, installing a solar system in our area does not mean that you are “off grid”. Your solar system will be “grid tied” and still interact directly with the utility grid to push and pull electricity. This means that you can still pull power from the grid when needed and can send excess solar power generated to the grid for net metering credits.
Your solar inverter will automatically shut down when it detects zero voltage coming from the grid. This is a built-in safety mechanism which prevents sending power to the grid when utility workers are conducting line work. That said, the system will not operate during an outage unless you integrate battery backup.
The system should be covered by homeowner’s insurance since it is installed on your home. We recommend contacting your insurance provider to let them know you will be installing a solar system in case a claim needs to be made in the future.
Ilumen Solar provides a 10-year bumper to bumper warranty for system installation, maintenance, repairs, and roof leaks related to each solar installation. Inverter and solar panel warranties are typically 25 Years.
In Illinois, adding solar to your home will not increase your property taxes. Illinois offers a property tax exemption for solar power systems, which means you are not taxed for the increase in home value your solar panels bring.
Since your solar system is tied into the grid, you will still receive an electric bill each month, however the amount owed on each bill will be lowered. If you come close to 100% offset, your bill will only reflect connection fees. Also, if qualified for net metering, your bill will show the amount of energy you sent back to the grid, as well as consumed from utility for that given billing period.
Inherently, a solar system should increase the value of your home or business. Similar to other home improvements, solar adds a significant value to your home or business by reducing your operating expenses. However, the price of your home is only worth what the buyer is willing to pay.
Solar Renewable Energy Credits (SRECs) were designed to enable solar system owners to sell their energy production back to the utility to help add to this percentage and reach that requirement. One SREC is the equivalent of 1,000 kilowatt-hours (kWh), or 1 megawatt-hour (MWh). Each SREC has a monetary value which helps offset the cost of the system. Ilumen Solar handles and submits all paperwork and applications for homeowners as part of the solar project to ensure these SREC payments are received.
