Why Certasun

Chicago skyline

We're Chicago area locals

Certasun is 100% locally owned and operated. When you work with us, you are partnering with friends down the street, not a corporation across country.

Moreover, we will never subcontract your installation to a third party.  Our own well-trained, licensed electricians and installers will install your system carefully and in compliance with all safety codes and regulations. 


Illinois home with solar panels

We're rooftop solar experts

Nine years ago, Certasun President Josh Lutton founded Woodlawn Associates, a management consulting firm serving the renewable energy industry.  One client described Woodlawn as the “premier consulting firm in the residential solar industry.”
