2018 Top Solar Developers

This is the list of 2018 Top Solar Contractors that primarily perform development work. These companies chose their primary service as “developer” when applying to the list, and they may also work as EPCs, rooftop installers, electrical subcontractors and installation subcontractors. The listed kilowatts installed by each company could be performed within multiple services and not just development.

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