Certasun Team

“We are very pleased with the work done by Certasun. The salesman was friendly, knowledgeable, and not pushy. The electricians and the technicians were hard working, friendly, and explained everything they needed to do. Would highly recommend Certasun to anyone thinking about going solar.”

Our History

Our president, Josh Lutton, founded Certasun in Chicago in 2018 after nearly 10 years of consulting in the renewable energy industry. He believed that a local solar company operating ethically and insisting on quality would inevitably thrive. Since then, a commitment to integrity and professionalism has guided every decision we’ve made.
