What Makes us Different?
We do everything in-house
It is not possible to guarantee a great customer experience when important parts of your project, such as sales, installation, or incentive processing, are handled by subcontractors. This is more common than you might think.
Our interests are aligned with yours
We guarantee the energy production of your system over its lifetime. We are also one of the very few solar companies that guarantees you’ll get the incentives you see in your installation agreement.
Your system will look great
We don’t take installation shortcuts to save cost or time. Don’t assume all solar panel installations look the same — they don’t.
You decide how to pay
We will advise you on the available financing options, but won’t push you to use any one of them.
“Certasun is absolutely the solar company you want to use…one of those extremely rare companies where you actually feel good working with them and like they have your best interests in mind.”
CHRIS D., GLEN ELLYN, ILLINOIS
“The solar panels were much better looking and less obvious than I thought they would be. Excellent communication and perfect workmanship are what you want when spending alot of money for a product so important as solar panels. Certasun passed with flying colors.”
MARY O., WESTMONT, ILLINOIS
“The reason I picked Certasun was trust. I am a lawyer and I looked at their contract. It was clean, it was fair, and it was laid out well. Working with Certasun gave me peace of mind.”
MATT G., CHICAGO
“Their knowledge, efficiency, communication, and commitment to excellence are unparalleled. Going solar with Certasun was one of the best decisions I’ve made for my home.”
WILLIAM I., SYCAMORE, ILLINOIS
“I could tell which ones were done by Certasun and which ones were done by other folks. If you are looking for something that looks like it was built with the house, then definitely go with Certasun.”
DARYL D., NAPERVILLE, ILLINOIS
“Every aspect of working with the Certasun pros was fantastic. And now we have a $14/month electric bill. What a dream! And our panels look great! I’m SO glad we went solar!”
JOY M., NILES, ILLINOIS
