Solar Panel Payback Calculator
Years to break even on a solar system
Thinking about solar? Enter the system cost, any incentives, your monthly power bill and how much of it solar will offset to estimate your payback period and long-term savings.
How solar payback works
Subtract incentives (like the federal tax credit) from the system cost to get your net cost. Divide that by your annual savings (the share of your bill solar replaces) to get the payback period. Most systems last 25+ years, so anything after payback is profit.
Estimate only — get quotes and check current incentives for your area.
