When it comes to solar energy, Colorado shines. Sunny days rule for more than a third of the year, and this abundant resource is harnessed through government-supported policies. In 2004, Colorado’s residents approved the nation’s first Renewable Portfolio Standards, and today the state’s RPS calls for 30 percent of the state’s electricity to be from renewable resources by 2020.

Colorado’s Solar
Report Card


To determine a grade for each state, our researchers and solar experts analyzed data on crucial solar-advancement criteria from the following sources:

We determined a rank from one to 10 for each state in each category. We then combined the scores with the following weights and assigned an overall grade for each state. Our goal is to encourage those considering solar for their homes to get a basic understanding of solar potential in their areas and discover the best opportunities for clean energy available.

Electricity Rate, 15%

Renewable Energy Policy, 30%

Interconnection Ease, 5%

Photovoltaic Potential, 10%

Electricity Costs in Colorodo

Colorado’s residential electricity costs are about $0.13/kWh, close to the national average. While higher electricity costs generally spur increased investment in solar, Colorado’s interest in solar is helped by the fact that solar installation costs in the state continue to drop, and solar customers enjoy certain tax exemptions, rebates, and net metering. Colorado is well on its way to reaching its 2020 RPS goal of 30 percent; in 2017, almost 25 percent of the state’s electricity came from renewable energy resources, including its 2,000 wind turbines.

CO Solar Policies & Incentives

The key to Colorado’s solar success lies in its first-in-the-nation Renewable Energy Portfolio Standard. This requirement has prompted the state’s utility companies to offer rebates worth thousands of dollars. In addition, utilities are required to offer net metering or paying solar customers for the excess energy they contribute to the grid. Although Colorado does not offer a tax credit for solar installations, customers are entitled to certain property and sales tax exemptions. Several financial options also are available for solar panel installations, including leasing and third-party financing.

A rebate is available to residential and small business customers who install a solar photovoltaic system or other renewable resource facility. Eligible systems are grid-tied within LPEA’s service area. For systems less than 10 kW, there is an upfront incentive of $16 per kW. Performance-based incentives are currently $1 per MWh and paid every six months for systems greater than 10 kW.
