Frequently Asked Questions

Can the City of Colton recommend a solar vendor to use to install panels at my home or business?
No, the City of Colton cannot make any recommendations on which solar vendor to use. You must do your own research as the property owner.

Does the City of Colton have a program where I can have them install solar for me?
No, the City of Colton does not install, service, or maintain solar panels.

How many solar panels can I install?
The solar system should be sized accordingly to the actual energy consumption in the home over the past 12 months. The annual output of kilowatt-hours (kWh) cannot exceed the 12-month kWh consumption. System size is capped at 100% actual load. No exceptions!

If I do not have 12-months of energy consumption, how do I determine my maximum system size?
If 12-months of energy data is not available, you can calculate the maximum install based on 2 watts per square foot of the property. For example, a 1,500 sq. ft. home can install a 3,000-watt system, also known as a 3kW system.
