About Us

Sopris Solar is named after Mount Sopris, a mountain that dominates the skyline of Carbondale and the lower Roaring Fork Valley outside Aspen. The mountain was named after Richard Sopris, a former mayor of Denver and part of the first European expedition in the Roaring Fork. This same adventurous spirit is what led to the formation of Sopris Solar 5 years ago.

At Sopris Solar, we pride ourselves on our culture and dedication to provide the most cost-effective solar installations to Colorado home and business owners. With the explosive growth of the solar industry, homeowners and businesses are inundated with offers from solar companies. Colorado’s 300+ sunny days and increasing utility rates have brought an influx of solar companies from California and Utah to the area. However, do these companies know the state like a local installer, more importantly, how long will they be in the area before they move on to greener pastures?

Sopris Solar provides full-service affordable energy solutions for homeowners, businesses, and non-profits throughout the Colorado area. We specialize in roof-mounted solar installations, ground mounts, solar farms, energy storage, geothermal heating/cooling systems, as well as removal and reinstallation insurance claims. More importantly, Sopris Solar is the only local solar company that has offices in and throughout Colorado. From Denver to Aspen, Fort Collins to Colorado Springs; our team has extensive knowledge of your community’s net-metering laws and current rebate programs. Our staff operates under the belief that the true value of solar isn’t necessarily dependent on the equipment that is installed on your home but based on the expertise and integrity of the installers.

Sopris Solar is committed to corporate social responsibility and helping to improve the quality of life for everyone as we sustain our environment for future generations. We are constantly striving to inspire these values in our employees, partners, and customers because this responsibility is integral to the success of our business and future of our environment.

Whatever your reason for going solar, let Sopris Solar help you get there.
