2020 Top Solar EPCs

This is the list of 2020 Top Solar Contractors that primarily perform engineering, procurement and construction (EPC) work. These companies chose their primary service as “EPC” when applying to the list, and they may also work as developers, rooftop installers, electrical subcontractors and installation subcontractors. The listed kilowatts installed by each company could be performed within multiple services and not just EPC work.

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

For more information on Solar Power World‘s annual Top Solar Contractors list and additional sublists, visit our Top Solar Contractors landing page.
