Solar Battery Storage Calculator
Estimate annual savings from home solar battery storage versus grid export
Home solar battery storage captures excess solar generation during the day for use at night. Without a battery, excess solar is exported to the grid at low rates.
💡
Tip: Pair battery storage with an off-peak tariff to charge cheaply from the grid overnight and discharge during peak times.
