2019 Top Solar Developers

This is the list of 2019 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 2019 Top Solar Contractors list, organized by kilowatts (DC) installed in 2018.

*Solar Power World incorrectly listed Carolina Solar Energy on the original 2019 list. The company should be listed at No. 20 overall. Previously reported Developer list standings may be reflected incorrectly as a result. This list is verified correct, as shown below.
