America's Top 5 Largest Solar Companies

Solar power is one of the fastest-growing industries in the world. Solar installations have grown at an annual rate of almost 40% since 2013 and are expected to continue growing for the foreseeable future. With so much solar growth, it’s not surprising that there are a lot of big players in this space.

Proving this point, there are 10 companies in America that produce solar panels on an industrial scale. These 10 companies produced almost 70% of the solar panels manufactured in America last year. These are America’s largest solar companies based on market capitalization as well as revenue generated from sales of their solar products.
