Our History  

 We’re residential solar experts.  In 2009 our president, Josh Lutton, founded Woodlawn Associates, a management consulting firm described by one client as the “premier consulting firm in the residential solar industry.”  While at Woodlawn, Josh and many of us at Certasun consulted with some of the largest and most successful solar installers, equipment manufacturers, and financiers on how to better operate their businesses.  Now, we’re excited to be working here in the Midwest!
