Denver, CO

Denver received the Gold designation for removing obstacles to solar energy development, including creating an online permitting checklist, reviewing local zoning codes, allowing solar by-right accessory use, cross-training inspection and permitting staff on solar PV, and providing a streamlined permitting pathway for small PV systems.
"Denver is proud to be a national solar leader, and we look forward to building on our achievements as one of the nation’s first participants in the SolSmart program. Going solar — saving money, energy and the environment — in Denver should be accessible to every community and every household, and with this partnership we will help to make that a reality." - Mayor Michael B. Hancock


In November of 2012, Denver was named the first Solar Friendly Community, part of a national effort sponsored by the U.S. Department of Energy to reduce the costs of installing solar power systems. One of the city’s signature programs is the Denver Energy Challenge, which allows residents to easily invest in energy efficiency and solar by providing free energy advising and low-interest loans. Residential loans start at 2.75% and can cover the purchase or lease a rooftop solar system, upfront costs to purchase shares in a community solar garden, a solar thermal system, and more.
