Solar Savings Calculator
Payback period and 25-year savings. Change the numbers and the result updates instantly.
How it works
Annual solar savings equal the electricity your panels produce multiplied by your electricity rate. Payback is system cost divided by annual savings. Electricity prices usually rise over time, which shortens payback.
Example
Check current incentives before buying. The federal residential clean energy credit ended for systems placed in service after December 31, 2025, so verify any state, local or utility incentives that still apply.
Tips
- Change one input at a time to see what moves the result most.
