Solar payback in Colorado (2026)

In Colorado, a typical 8 kW home-solar system costing about $24,000 ($3/W, no federal credit in 2026) has an estimated simple payback of 9.9 years and roughly $49,962 in net savings over 25 years. This assumes an average rate of 16.74¢/kWh and ~1,620 kWh produced per kW each year.
