Batteries in 2026
The federal battery discount is real — and it steps down over time
Under the Australian Government's Cheaper Home Batteries Program, eligible batteries between 5kWh and 100kWh can create small-scale technology certificates (STCs), which we assign as an up-front discount of around 30% on the installed cost. Since 1 May 2026 the STC factor is tiered by capacity and is reviewed every six months, so the discount reduces over time.
- • 0-14 kWh of usable capacity: STC factor applied at 100%
- • Above 14 up to 28 kWh: applied at 60%
- • Above 28 up to 50 kWh: applied at 15%

Finance available
Some customers pay for their system outright, and others prefer to spread the cost by arranging finance through an independent finance provider. The choice is entirely yours, and the system, price, equipment and warranties we quote are the same either way.
Sunquest Energy Pty Ltd does not provide consumer credit or deferred payment arrangements and is not the credit provider. Any credit contract is between you and the independent finance provider you choose, under that provider's own terms.
Finance is voluntary and always subject to the relevant finance provider's eligibility requirements, credit assessment, approval, fees and terms and conditions. We make no promise about approval, rates or repayments.
We do not provide financial, credit, tax or legal advice, and estimated bill savings should never be treated as a guaranteed way to meet repayments. If you are considering finance, read the provider's documents carefully and consider independent advice.
