What a battery is worth in SA

A battery stores solar power you'd otherwise export, so you use it in the evening instead of buying from the grid. In SA that swaps a feed-in credit of about 4c per kWh for a usage price of about 42c.

Questions

Is there a battery rebate in South Australia?

Yes. The federal Cheaper Home Batteries Program applies in every state and territory, including South Australia. SA's REPS battery incentive is now open only to concession, hardship and some rental households, at up to about $2,050 on top of the federal rebate.

How much is the battery rebate in SA?

The federal rebate depends on the battery's usable capacity, not where you live. A 13.5 kWh battery installed in May–Dec 2026 earns about $3,458, at $38 per certificate. Your installer sets the price they credit and may deduct fees, so check the quote.

When does the battery rebate drop?

On 1 January 2027. A 13.5 kWh battery installed on or after that date earns about $2,888, $570 less. The date that counts is when it's installed and commissioned, not when you sign.

Is a battery worth it in SA?

It depends on the gap between what you pay for power and what you're paid for exporting it. In SA the typical usage price is about 42c per kWh and the feed-in tariff about 4c, so every kWh a battery stores for the evening is worth roughly 42c instead of 4c. For a family of four in Adelaide on a $650 quarterly bill, the planner suggests 10 kW of solar with a 5 kWh battery, saving about $2,086 a year.
