2018 Top Commercial Solar Contractors

This is the list of 2018 Top Solar Contractors that primarily work in the commercial market. These companies chose their primary market as “commercial” when applying to the list, and they may also work in the utility and residential markets. The listed kilowatts installed by each company could come from multiple markets and not just commercial projects.

The companies below are a segmented portion of the overall 2018 Top Solar Contractors list, organized by kilowatts (DC) installed in 2017.
