What home batteries cost in 2026
Battery pricing depends on capacity (kWh), brand and whether backup is included. The big change for 2026 is the federal Cheaper Home Batteries Program, which discounts eligible battery systems by roughly 30%, applied upfront on your invoice. As a rough example, a 10kWh battery in Melbourne might receive in the order of $3,000+ off from the federal discount alone.
Because net prices move with the discount and your system design, the honest answer is that your exact figure comes from a proposal. See our battery storage page for how we size batteries to your usage.
How the incentives work now
- Federal Cheaper Home Batteries discount — ~30% off eligible batteries, applied at point of sale. This is the main battery incentive for Victorians in 2026.
- Victoria's interest-free battery loan — closed to new applications in 2025, so it's no longer part of the mix.
- Solar rebate — if you're adding panels at the same time, the Victorian Solar Homes solar rebate may also apply. See the rebates guide.
Realistic payback
A battery earns its money by storing cheap daytime solar and using it during the expensive evening peak, instead of exporting it for a small feed-in tariff. For a typical Melbourne home, a well-sized battery adds roughly 7–9 years to the solar payback — but the gap has narrowed considerably with the federal discount and rising evening tariffs. Payback improves the more of your own energy you shift into the evening.
Is a battery worth it for you?
A battery makes the most sense if you: use a lot of power in the evening, have (or are adding) enough solar to charge it, want some backup during outages, or are electrifying (EV, induction, heat pump). If your usage is mostly daytime, more solar may beat a battery. We model both at your free assessment and show you the numbers before you decide.
Frequently asked questions
