★ 2025 Top Solar Contractors

2025 Top Commercial Solar Contractors

This is the list of 2025 Top Solar Contractors that perform work in the commercial, industrial, agriculture and municipal market. The listed kilowatts installed by each company on this Commercial Contractor list were only installed within the commercial market. Companies could also be listed on additional market lists with their installation numbers within those respective markets reflected on those lists.

Contractors chose their “primary project installation type” for the commercial market, either ground-mount or rooftop. While Solar Power World is not providing project-type sublists, these secondary identifiers can be used as additional sorting tools when reviewing market lists.

The companies below are a segmented portion of the overall 2025 Top Solar Contractors List, organized by kilowatts (DC) installed in 2024.

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