About Us

Certasun is Illinois’s premier home solar company. We offer 10 years of solar industry experience, are 100% locally owned, and live in the towns and neighborhoods where we do business.

We combine industry leading equipment, expert design, and world class installation experience to create a beautiful and productive solar system for each of our customers.

Certasun is a SunPower Elite Dealer and exclusively installs SunPower solar systems, the top-rated solar equipment on the market. We work closely with each homeowner to create a custom solar system design that meets their energy needs and aesthetic preferences. As part of our No Surprises Guarantee, all of our installations are completed by our expertly trained in-house team of installers and electricians.

We’d be thrilled to put together a proposal for you to bring sustainable solar energy to your home.
