Illinois's Premier Home Solar Company

Start Turning Sunlight Into Savings






Imagine This Is Your ComEd Bill Today

Many Illinois homeowners are frustrated with their high energy bills and are tired of paying for nuclear and coal.

With Solar You Could Be Paying Much Less

Qualifying homeowners can go solar with zero up-front cost and pay less every month than they would otherwise pay their utility.

*If you buy your system outright, your monthly solar bill would be $0 and your monthly savings would be significantly higher. 

Going Solar is Easy

Based in Buffalo Grove, Certasun helps homeowners go solar and start saving on their electricity bills.  Why pay ComEd extra for coal-produced energy when you can produce your own solar energy for less?
