Another record-breaking year in the books!
The United States installed 50 GW of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades. More than 16 GW was installed in the fourth quarter alone. The companies behind those huge numbers? All right here on the 2025 Top Solar Contractors List.
Working in the solar industry has never been easy; it sometimes feels like two steps forward, one step back. A record-breaking installation year, then a new round of lobbying Congress to save our progress. That’s why we must celebrate when we can, and Solar Power World is happy to present the 2025 class of the best installation companies in the country.
Over 400 contractors make up this year’s list, installing solar in every state and also Washington, D.C., Puerto Rico and Guam. While the commercial and residential markets are the most popular for our Top Solar Contractors, there are quite a few who participate in all four core markets. It’s great to see that diversification among our listees. It will help when adapting to the latest market conditions to keep all our hardworking solar installers employed in this vital energy industry.
That’s who we’re really celebrating on the 2025 Top Solar Contractors List — the thousands of Americans behind the company names. Your work is valued and appreciated, and we hope you enjoy learning the stories of other successful individuals featured in this magazine.
We can’t wait to celebrate another year of tenacity in the solar market with our 2026 List — our 15th edition! See everyone soon.
