2023 Top Commercial Solar Contractors

This is the list of 2023 Top Solar Contractors that perform work in the commercial and industrial (C&I) market. The companies on this list either chose their primary market as “commercial” or “both residential and commercial.” These companies either installed the entirety of their 2022 portfolio in the commercial market or split some of their projects within the residential market. The listed kilowatts installed by each company on this Commercial Contractor list were only installed within the commercial market. Companies could also be listed on the Residential Contractor market list with only their residential installation numbers reflected on that list.

The companies below are a segmented portion of the overall 2023 Top Solar Contractors List, organized by kilowatts (DC) installed in 2022.
