Savings and payback assume standard electricity prices for New South Wales, no price rises and no battery wear. Rebates assume installation today.
Not sure what size you need? The planner works it out from your bill.
Plan my systemHow it's worked out
- Rebate: the federal battery rebate for each model's usable capacity if it's installed today, at a typical $38 per certificate.
- Price: your quote if you enter one. Otherwise a typical installed price for that size, the same for every brand, so enter real quotes to compare brands fairly.
- Savings: the same hour-by-hour model as the planner. Each battery stores spare solar for the evening, at your state's standard electricity price and feed-in rate.
- Overnight: how much of a typical night's use each battery covers, after charging from your solar on an average day.
What else to compare
- Warranty: years, and the energy it guarantees over that time. Ten years is typical.
- Power: how many kW it can supply at once. Around 5 kW suits most homes; ducted air-conditioning may need more.
- Blackout backup: whether it powers the whole home, selected circuits, or nothing in a blackout, and whether that costs extra.
- Room to grow: whether you can add modules later, and whether it works with your inverter.
