solar panels in CFU Simple Solar Garden

Simple Solar

Simple Solar is a community solar project, or a large collection of solar panels built and maintained by CFU located near Prairie Lakes Park.

It is currently the largest community solar project in Iowa and has a total capacity of 1.5 MW. 

The project offers a flexible and affordable way to support clean energy. When the array opened more than 1,200 residents and businesses purchased solar units. Customers who purchased units receive a utility bill credit based upon the output from the panels.

Energy generation started at the site on April 1, 2016. The project is located near Prairie Lakes Park in Cedar Falls on eight acres donated by the city of Cedar Falls.

Interested in solar units?

As customers who own units move out of CFU's service territory, CFU buys back units and they become available again for purchase. Call 319-266-1761 or email energyservices@cfunet.net to be added to a waitlist. Customers on the waitlist will be enrolled yearly in November if units are available.
