About Certasun

Certasun is Illinois’s premier residential solar company.  We are 100% locally owned and live in the Chicago and suburban communities we serve. We are committed to an exceptional customer experience and are thrilled to bring affordable, clean solar energy to Illinois.

We’re residential solar experts.  Nine years ago 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.  However, because other states have historically enjoyed larger solar markets, we spent most of our time working in California, Hawaii, and on the East Coast.  Now, we’re excited to be working here in Illinois!

Service Area

Certasun serves the entire Chicagoland area, including Cook, DuPage, Kane, Lake, McHenry, and Will counties.

Live further away?  Please contact us and we would be happy to discuss your solar options.


We’re hiring!  Please see our careers page for more detail on open positions.
