Common questions
How much does a home battery cost in 2026?
A typical 10 kWh system costs $10,000–$14,000 installed before rebates. After the federal Cheaper Home Batteries Program rebate of $330/kWh, most households pay $7,000–$11,000. Victoria and South Australia have additional state schemes that reduce costs further.
What is the federal battery rebate and how does it work?
The Cheaper Home Batteries Program pays $330 per kWh of battery capacity. Your CEC-accredited installer applies it at the point of sale — you never claim it yourself. For a 10 kWh battery that is $3,300 off the invoice. The rebate steps down annually until 2030.
Do I need solar panels to get the rebate?
The federal rebate requires the battery to be paired with a solar system — either existing panels or new ones installed at the same time. Some state schemes have similar requirements. A battery without solar is still eligible in some cases — ask your installer to confirm.
How long does it take to pay for itself?
Households with solar panels typically see payback in 6–9 years. The battery stores cheap solar energy during the day and uses it in the evening instead of buying from the grid at peak rates. Without solar, payback is longer because the benefit depends on time-of-use tariff arbitrage alone.
