Solar Panel ROI Calculator

Calculate the return on investment, payback period, and lifetime savings of installing solar panels on your home.

Solar is a great investment when

  • Your electricity rate is $0.12+/kWh
  • You get 4+ hours of daily peak sunlight
  • You plan to stay in your home 7+ years
  • Your roof is south-facing and unshaded
  • State incentives stack with the federal credit

Solar may not be worth it when

  • Your electricity rate is very low ($0.06/kWh)
  • Your roof needs replacement within 5 years
  • You are in a heavily shaded location
  • You plan to move within 3 years
  • Your state has no net metering policy
