Solar Program

City of Colton residents may apply to install a residential solar system using the PowerClerk online portal. All information will be loaded directly through the website.

Customers may install systems up to 100% of their actual consumption for the past 12 months in the home. The City of Colton does not allow for any oversizing, there will be no exceptions. If a customer does not have a full 12 months consumption history, the maximum they will be approved to install is 2 watts per square foot.

If you need your electric consumption data, please complete the online form. The completed information will be submitted to the customer within 3 business days.

Please be advised, the City of Colton Electric Utility requires all solar installations to have a Production Meter and two AC Disconnects.  If you elect to provide your own Production Meter, one disconnect will be acceptable.
