This webpage provides information on solar arrays that generate electricity for Johnson County government facilities. If you are considering a solar array project in the county's unincorporated area, please visit Building Services for the Solar Photovoltaic (PV) System guidelines and checklist. If you would like to learn about the 2021 solar group buy for adding solar to your own home, business or farm, visit Grow Solar Linn + Johnson Counties.

In 2015, Johnson County was the first county in Iowa to enter into a Power Purchase Agreement (PPA) for solar photovoltaic arrays to power some of its buildings. Since then, the County has entered into additional PPAs and made several outright purchases of solar arrays.
