How it works

Monthly saving = monthly bill × offset % ÷ 100. Yearly saving = monthly × 12. The 25-year figure multiplies the yearly saving by 25 (panels typically last 25+ years). It ignores rate inflation, which would make real savings larger.

Frequently asked questions

What offset percentage is realistic?

A system sized to your usage often offsets 70–100% of your bill. Fixed charges and night-time use mean it is rarely a full 100% unless you add a battery.

Does this account for the system cost?

No — this shows savings only. To include the install cost and find your break-even point, use our solar panel payback calculator.

Will my savings grow over time?

Usually yes — as electricity prices rise, the value of the power your panels produce increases, so real savings tend to beat this estimate.
