Is a home battery worth it in Victoria?

What a home battery does

Solar panels produce most of their power in the middle of the day, which is often when homes use the least. Without a battery, that spare power is sent to the grid. A battery stores it so you can use it in the evening and overnight, when you would otherwise be buying electricity.

Some batteries can also be set up to provide backup power during an outage, but not every system does this automatically. If backup matters to you, raise it at the quote stage, because it affects how the system is designed and wired into your switchboard.

The Cheaper Home Batteries Program

The federal Cheaper Home Batteries Program started on 1 July 2025. According to the Department of Climate Change, Energy, the Environment and Water, it offers households, businesses and community organisations a discount of around 30% on the upfront cost of eligible battery systems between 5 kWh and 100 kWh, connected to new or existing solar.

You do not apply to the government for it. The discount is delivered through the Small-scale Renewable Energy Scheme as small-scale technology certificates (STCs), and is usually passed on by your installer or retailer as an upfront reduction or a rebate after installation. The Clean Energy Regulator administers the program. To be eligible, the battery must be on the Clean Energy Council approved list, be capable of joining a virtual power plant, and be installed by an installer accredited by Solar Accreditation Australia with a battery endorsement.

The discount is changing over time

Changes to the program came into effect on 1 May 2026. The number of certificates a battery earns per kilowatt-hour now steps down every six months until 2030, and support tapers for larger batteries. Under the current rules, the full rate applies to the first 14 kWh of usable capacity, with reduced rates above that, and certificates can only be claimed on up to 50 kWh.

In plain terms, the discount you receive depends on the date your battery is installed and its size. These settings are reviewed regularly and can change, so always check the latest details on the DCCEEW and Clean Energy Regulator websites before you commit. Solar Victoria's earlier interest-free battery loans are no longer taking applications.

When a battery makes more sense

A battery tends to be better value if you already send a lot of solar to the grid, if you use a good amount of power in the evening, or if your feed-in tariff is low. Households planning an electric vehicle, electric heating or a switch away from gas can also get more use from stored energy.

It may be less compelling if your solar system is small, if you already use most of your solar during the day, or if your evening usage is light. The government advises that bigger is not always better: a battery that is too large for your solar or inverter can limit the benefits. Every home is different, so be wary of anyone promising a set saving or payback period.

Getting the right advice

Before deciding, gather a year of power bills, and if you have a smart meter, your interval data. The government recommends getting quotes from more than one installer, and asking each one to explain the value of the discount, when you will receive it, the warranty, and the assumptions behind any payback estimate.

A battery connects into your switchboard and solar system, so the electrical side matters. As licensed electricians in Bendigo, we can look at your existing setup, explain whether a battery suits your home, and flag anything like a switchboard upgrade that should be planned for.
