Solar Payback Calculator
Calculate how many years it takes for solar panels to pay for themselves based on cost and annual savings.
How It Works
Enter the solar system cost, any incentives or tax credits, and annual electricity savings. The calculator shows simple payback period and 25-year return on investment.
Formula
Payback Years = (System Cost - Incentives) / Annual Savings
Frequently Asked Questions
What is the federal solar tax credit?
The US federal Residential Clean Energy Credit is 30% of installed system cost through 2032. A $20,000 system gets a $6,000 tax credit, reducing net cost to $14,000.
What is a typical payback period?
Most residential solar systems in the US pay back in 6-12 years. With electricity prices rising, payback periods are shortening. Panels are warranted for 25 years.
