Top 10 Solar Batteries in Australia: Best Brands, Prices & Performance
Worried about rising energy bills? You’re not alone. The average Australian household spent over $300 per quarter on electricity last year.
The solution? Investing in a solar battery.
Solar batteries provide easy access to clean, renewable energy and serve as a backup power source. If you’re looking to reduce reliance on grid electricity (which is costly during peak hours), they’re the key to energy independence.
The best solar battery systems balance performance, efficiency, flexibility, storage capacity, warranty, and price. Let’s take a look at the top 10 solar batteries currently available, and how to select the right solar setup for your home.
How Much Do Solar Batteries Cost?
On average, solar batteries cost between $5,000 and $15,000 in Australia.
Slightly out of your budget? The government has invested over $7 billion in its Cheaper Home Batteries Program, which could help 2 million Australians install solar batteries by 2030.
This reduces installation costs via solar rebates awarded under the Small-scale Renewable Energy Scheme (SRES). Successful applicants receive a discount of around 30%, with potential savings of up to $372/ usable kWh. Now is the perfect time to invest in one of the top 10 solar batteries in Australia!

Which Solar Battery Should You Choose?
If you expect your usage to grow in the future, select a solar battery (from a trusted brand!) with a capacity 20 to 30% higher than your average energy requirements.
Look for a good throughput warranty, too: the total energy a solar battery should deliver in terms of megawatt-hours. A 10 mWh throughput, for instance, means the battery will remain operational until 10 megawatt-hours of energy have been stored and delivered.
Once your battery discharges the minimum amount guaranteed by the supplier, performance warranty benefits end. Choosing batteries with throughput warranties that aren’t solely based on the time you’ve owned them helps avoid uncertainty and disappointment about their potential lifespan. It’s also easier to assess a system’s overall value by comparing the throughput warranty to your expected energy needs.
Finally, be sure to use only accredited products and installers. As Brisbane’s trusted name in solar battery installations, Volteam works exclusively with brands that prioritise safety and longevity.
