Battery storage savings & payback estimator
Get an indicative estimate of annual savings and simple payback for a commercial battery storage system. Adjust the inputs to your site — we confirm exact figures in the project quote.
This is a simplified, indicative estimate only. It assumes the battery cycles at the chosen rate and captures the price spread between your high and low prices at the stated round-trip efficiency. It does not model tariff detail, demand charges, degradation, taxes or funding. Actual savings and payback depend on your load profile, tariff and system design and are confirmed in the Sunket Supply project quote.
