2020 Top California Solar Contractors

This is the 2020 list of Top Solar Contractors completing work in California. The kilowatts listed as being installed in the state reflect only kilowatts installed in California in 2019. Companies listed on this state list could be headquartered in other states, participate in any market (residential, commercial, utility) and provide any installation service (EPC, developer, rooftop solar installer, installation subcontractor, electrical subcontractor).

The listed kilowatts installed by each company in California could come from installations in all markets (residential, commercial, utility) but only within California state lines.

The companies below are a segmented portion of the overall 2020 Top Solar Contractors list, organized by kilowatts (DC) installed in 2019.
