Solar Battery Price Australia

What is a Solar Battery?

A solar battery is a device that stores excess energy generated by your solar panels during the day. Instead of sending unused electricity back to the grid, a solar battery lets you store it for later use, especially during the evening or on cloudy days.

With the rising cost of electricity, solar batteries in Australia are becoming increasingly popular among homeowners and businesses looking to maximise their solar investment and gain energy independence.

Solar Battery Price in Australia: 2025 Overview

The average cost of solar batteries in Australia in 2025 ranges from $6,000 to $16,000, depending on the battery size, brand, technology, and installation costs.

Here’s a quick snapshot of the typical solar battery prices:

Battery Size (kWh) Approximate Price (Installed)

5 kWh $6,000 — $8,000

10 kWh $10,000 — $13,000

13 kWh $12,000 — $16,000

These prices can vary based on location, specific installer rates, and available government rebates.

Factors Affecting Solar Battery Price in Australia

1. Battery Capacity (Size in kWh)

The larger the battery, the more energy it can store, and the higher the price. Choosing the right battery size depends on your daily energy consumption and solar panel output.

2. Battery Brand and Technology

Popular solar battery brands in Australia like Tesla, Sungrow, LG Chem, and BYD offer varying prices. Lithium-ion batteries are the most common and cost-effective, while newer technologies like flow batteries are generally more expensive.

3. Installation Costs

Installation fees can range from $1,000 to $3,000, depending on the complexity of your system and your installer’s pricing structure.

4. Hybrid vs. Add-On Systems

If you’re installing a hybrid solar system (solar panels and battery together), the cost is typically lower than retrofitting a battery to an existing system.

5. Government Rebates and Incentives

Several Australian states offer solar battery rebates and interest-free loans that can significantly reduce your upfront cost.

Is a Solar Battery Worth It in Australia?

Financial Benefits

A solar battery helps you:

• Reduce your reliance on the grid.

• Save more on your energy bills.

• Get the most out of your solar system by storing excess energy.

Energy Independence

With a solar battery, you can run your home with stored solar power even when the sun isn’t shining, protecting yourself from rising energy prices and blackouts.

Environmental Impact

Using stored solar energy helps reduce carbon emissions, supporting a cleaner and greener Australia.

Solar Battery Payback Period in Australia

The average payback period for solar batteries in Australia is currently between 8 to 12 years, depending on your energy consumption, electricity rates, and available rebates.

If you combine your solar battery with a Time-of-Use electricity plan, you can shift your energy usage to off-peak rates, potentially reducing the payback period.
