What Payback Period Means
The payback period is an estimate of how long it takes for cumulative electricity bill savings to equal your net investment (system cost minus any subsidy received).
It's an indicative figure — actual payback depends on your consumption pattern, tariff, system performance, maintenance and any changes in electricity pricing over time.
Estimating Your Own
You can get a rough, indicative estimate using our solar calculator, which factors in your bill, roof details and applicable central financial assistance.
For a precise figure, a site survey and detailed quotation from your installer will give the most accurate picture.
