This is the 2023 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 2022. Companies listed on this state list could be headquartered in other states, participate in any market (residential, commercial, community solar, utility) and provide any installation service (EPC, developer, installer, installation subcontractor, electrical subcontractor, sales partner).
The listed kilowatts installed by each company in California could come from installations in all markets (residential, commercial, community solar, utility) but only within California state lines.
The companies below are a segmented portion of the overall 2023 Top Solar Contractors List, organized by kilowatts (DC) installed in 2022.
