About Illinois Solar

Dedicated to Cutting Your Energy Costs

Illinois Solar Services is a locally owned and operated company established to help residents, businesses, farmers, and municipalities become energy independent and save money long term. With inflation lessening supply by shutting down energy plants — along with increased demand for energy — utility charges are continuing to rise.

What can we do to ease the strain of growing energy costs?

The answer is simple: Use state-of-the-art equipment available to access the sun and supply your own energy. Take control of your utility expenses with the best technology, financing, and warranty. Not all solar products are the same. We pride ourselves on providing the highest quality products from our modules to microinverters. We do NOT take shortcuts and we work with our partners, Oberlander Electric and RNS Electric, to ensure your system is done right and will work for decades.


Modules (Panels) — Depending on the situation, we may use modules from any of the following manufacturers: Jinko, Q Cells, REC, Silfab, and other trusted sources. Our standards for selecting the right panel will depend upon your specific setup and need — from roof mounts to ground arrays, we choose the right panel to help maximize your space and efficiency.

Microinverters (DC to AC) — We use just one source for microinverters: Enphase. The leader in technology for microinverters, Enphase gives us many options to support your needs, allowing us to provide sunlight-only backup systems, battery backup systems and smartphone monitoring. Using Enphase microinverters allows us to combine high tech with high touch and gives you the assurance of knowing your system is working well.


The full cost of your solar installation must be paid for when the system is installed and the interconnection is complete. Federal and state incentives may take time to arrive, so most customers finance their purchase and pay it off when incentives come in.

Contrary to what some misguided advertisements tell you, the system costs are not always covered completely by federal and state incentives. A small portion of the remaining costs tend to be financed over time. This is still a good option because you lock in a low fixed payment until you pay off the loan. This protects you from rising utility charges and allows you to become energy independent.

Having a great loan program can be critical in making the right decision to convert to solar. This is where our lending partner, Hometown Community Banks, can help. They offer a flexible and unique process to allow 100% financing for qualified buyers. Most customers end up with a fixed payment less than their current utility bill, giving them immediate monthly savings. For more questions about the loan program and qualifications, contact us at 888-418-5585.


Most solar companies only stand by their product through the manufacturer’s limited warranty. However, if you need to repair or replace a part of your system, that warranty won’t cover the shipping and labor to replace the part. This practice did not work well with us, so we searched and found a better solution. We are proud partners with Solar Insure, which offers customers the peace of mind that their system is being monitored and warrantied for 30 years. Check out their solar warranty comparison and preview a sample warranty.

When you purchase through Illinois Solar Services, the warranty is included! You can rest easy knowing your system is being monitored. If an issue arises, it will be proactively addressed. For more questions about the warranty, contact us at 309-444-0982.
