Solar power in Colorado has grown rapidly, partly because of one of the most favorable net metering laws in the country, with no limit on the number of users. The state was the first in the nation to establish a Renewable Portfolio Standard for its electric utilities.

Colorado consumers typically obtain varying amounts of solar power from rooftop solar, community solar gardens, and larger solar farms. Several thousand people are employed in solar-energy-related activities throughout the state.

The Colorado Solar Energy Industries Association (COSEIA), a state affiliate of the national non-profit Solar Energy Industries Association, supports solar use and industry growth through its efforts which include both business and residential consumer education.
