2013 Top 25 Utility Solar Contractors

Renewable Portfolio Standards (RPS) have been key drivers of utility-scale solar across the United States.

Utility solar companies, especially these top 25 utility solar contractors from the Solar Power World Top 250 Contractors list,  serve as industry leaders to promote investment into research and the continued development of innovative solutions to help utility solar become a mature, self-functioning industry.
