Frequently Asked Questions
Is a home battery worth it in Australia?
It depends on your feed-in tariff vs. import rate gap. With feed-in tariffs as low as 3–6 cents/kWh and import rates at 28–35 cents/kWh, batteries are becoming more viable — especially with VPP (Virtual Power Plant) programs that offer bonuses.
What is the Tesla Powerwall 3 price in Australia?
As at 2026, the Tesla Powerwall 3 (13.5 kWh) has a recommended retail price of approximately $14,000–$16,000 installed, before any state rebates.
What government rebates are available for batteries?
Victoria offers the Solar Homes battery rebate (up to $2,950). SA has the Home Battery Scheme. Some states offer VPP programs. Federal STC credits apply to solar+battery systems.
