★ 2025 Top Solar Contractors
2025 Top Solar Contractors
Solar Power World, the industry’s leading source for technology, development and installation news, presents the 2025 Top Solar Contractors List. The list ranks applicants according to their influence in the U.S. solar industry in 2024.
The list shows where a company is located, its installation markets (utility/U, commercial/C&I, community solar/CS, residential/R) and its primary service (EPC, developer, solar installer, installation subcontractor, electrical subcontractor, sales partner). Companies choose their primary service. That does not mean they only work in these areas. Our market lists reflect only kilowatts installed in those specific markets, and contractors could work in multiple markets. Ranks are determined by the number of kilowatts (DC) a company was involved with installing in 2024 in the United States only.
2025 Contractors by market:
- Top Utility-Scale Contractors
- Top Commercial-Scale Contractors
- Top Residential-Scale Contractors
- Top Community Solar Contractors
