ELECTRICITY CALCULATOR
Solar simple payback
Estimate simple payback from installed cost and annual savings.
How this calculation works
(Cost − upfront grant) ÷ (annual savings − annual maintenance). This simple calculation ignores financing, inflation, degradation and future changes in tariffs; a non-positive annual saving has no finite payback.
