Colorado enacted S.B. 07-145 in April 2007, authorizing counties and municipalities to offer property or sales tax rebates or credits to residential and commercial property owners who install renewable energy systems on their property. 

Eligible renewable energy property is defined as "any fixture, product, system, device or interacting group of devices that produce electricity from renewable resources, including, but not limited to, photovoltaic systems, solar thermal systems, small wind systems, biomass systems, or geothermal systems."

The incentive is administered at the local level by individual cities and counties. Individuals should contact the cities or counties where their property is located to see if a tax rebate or credit has been established in their community.
