Solar Panel ROI: How Long Do Solar Panels Take to Pay for Themselves

Blog Updated: June 2026

Adding solar to your home is an opportunity to save money while making a difference for the planet we all share. Combined with the fact that home solar offers a stable and attractive return on investment (ROI), installing solar is a win-win for thousands of homeowners in Colorado. But how do you assess the value and the ROI of solar for your home? The payback period is a common metric used to assess the value of solar because it shows how long your solar panels take to pay for themselves. 

With solar, the sun provides a steady flow of cash savings from the solar panels on your rooftop. Without solar, you’ll continue to send your money to the utility company with no payback or ROI in sight. Solar is the home improvement project that pays for itself over time; what other project can say the same?

Key Takeaways for Solar Panel ROI

  • Payback period: The payback period is calculated by taking the overall system price and dividing it by the average projected solar savings each year to find out how long your solar panels will take to pay for themselves. 
  • Buy energy in bulk: If your system is paid off in 13 years, one way to think of it is that you’re buying energy for 25 years plus for the cost of 13 years’ worth of energy instead. It’s like buying your energy in bulk.
  • Colorado average payback period: Our customers see payback periods that are between 12-15 years on average.
  • Energy independence: There is no payback period when you pay the utility company, and Colorado utility rates are likely to rise significantly over the years. Solar gives you energy independence.

What is the Payback Period?

The payback period is calculated by taking the overall system price and dividing it by the average projected solar savings each year to find out how long your solar panels will take to pay for themselves. For example, if the overall price for your solar panel system is $18,200, and you are savings $1,300 off your utility bill each year with solar, then your payback period will be 14 years, an average payback period for systems along Colorado’s Front Range.

The payback period will tell you how long your solar panels will take to pay for themselves, but it doesn’t consider the full lifetime value of the system. Solar panels come with 25-year warranties, but many systems will still produce well beyond the warranty period. If your system is paid off in 14 years, one way to think of it is that you’re buying energy for 25 years plus for the cost of 14 years’ worth of energy instead. Think of it like buying in bulk; buying groceries in bulk may have a higher up-front cost, but the cost per unit is lower and saves you money in the long run. Solar is the same.

And after your system is paid off, you’ll be enjoying free energy from the sun for many, many more years, to the tune of thousands of dollars. This is all in addition to the increase in your home’s value and the environmental benefits that come with installing solar on your home.

Our customers see payback periods that are between 12-15 years on average. Your payback period will depend on your electricity usage, electricity rates, and how compatible your roof is for solar. In general, if you have higher electricity rates and high usage, you will see a shorter payback period than someone who installs a small system to offset minimal electricity usage in an area with low electricity rates. The size and complexity of your system and availability of solar incentives will also affect your payback period.

Gain Energy Independence

The payback period is often used as a key metric for home solar, but it doesn’t capture the whole story. When considering the cost of solar, compare it to the cost of your electricity now. What is the payback period on your current utility expense? Of course, you never see a return on the money you send off to the utility company, but more than that, Colorado utility rates are likely to rise significantly over the years.

A home solar panel installation protects you from rising energy costs and gives you energy independence. You’ll have your own power-producing asset on top of your roof, capturing sun rays and turning them into solar savings.
