★ 2025 Top Solar Contractors

2025 Top Solar EPCs

This is the list of 2025 Top Solar Contractors that primarily perform engineering, procurement and contracting (EPC) work. These companies chose their primary service as “EPC” when applying to the list, and they may also work as developers, installers, electrical subcontractors, installation subcontractors and sales partners. 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 2025 Top Solar Contractors List, organized by kilowatts (DC) installed in 2024.
