Like many of its customers, Colorado Springs Utilities (CSU) recognizes the importance of solar energy. It helps protect the environment, diversifies our energy supply and creates energy independence. And with about 300 days of sun per year, Colorado is an excellent platform for this type of renewable energy. If you are considering adding solar panels to your home or business, be sure to first check out the CSU rebate program. Depending on the installation, up to 40 percent of the total system cost could be covered by rebates and tax credits.
