Big solar farms in Colorado
Find out where big solar energy farms are in Colorado and the number of homes they power with clean renewable solar energy.
Colorado ranks 10th in the country for solar generation. Solar is a free, invaluable energy source. Over the last decade solar panels have become much more affordable, making it accessible to a lot more people.
With over 300 sunny days a year, solar power offers Coloradans the ability to become more energy independent, support energy resiliency in local communities and shield ourselves from gas price spikes.
