Certasun Exclusively Installs SunPower—
The World’s Most Powerful Solar

When you choose to go solar, you should expect your system to last decades.
That’s why Certasun exclusively installs the SunPower Equinox solar system, which includes the world’s most powerful, attractive, and durable solar panels.

Did you know…solar is often cheaper than your utility?

You can buy your solar system outright and make a great investment that will pay for itself and increase the value of your home.  Or, you can choose a financing option with zero up-front cost that saves you money every month.  Literally, your solar cost can be less that what you pay for electricity today.
