Why Certasun

Chicago skyline

We're Chicago area locals

Certasun is 100% locally owned and operated. We know solar, and we know you
never put ketchup on a hot dog. When you work with us, you are partnering with
friends down the street, not someone across the country.

We also understand exactly how the Illinois incentive program works and will apply for the incentives on your behalf.  We can tell you how much your incentive payment will be and approximately when you will receive it.

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 us as the “premier consulting firm in the residential solar industry.”

We consulted to many of the largest 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.  We are thrilled to be working in Illinois.


We use premium equipment

Certasun uses SunPower equipment,
the highest-quality, highest-efficiency,
best-warrantied, best-looking products in
the industry. 

SunPower equipment comes with a 25-year Complete Confidence warranty that covers both equipment and labor in the unlikely event of any problem.
