In Colorado, we are very lucky we live in a state that is proactive related to stimulating the use of renewable energy sources. Along with the Federal energy credit of 30% on the total cost of the installation; the utility rebates available in some of our utility jurisdictions help reduce the cost to build a PV system. We also have a Colorado state energy credit for solar installations that exempts the 2.9% State based sales tax, and the 1.2% RTD sales tax. Some local municipalities have also chosen to exempt solar PV system from their sales tax, but that is specific to the city or county where you’re home or business is located.
