Understanding Solar Battery Price in Australia — 2025 Guide by Ads Solar

As Australia’s solar energy sector continues to thrive, more homeowners and businesses are investing in solar battery storage to maximise their solar panel systems. If you’re considering solar energy, you’ve likely come across the topic of solar battery prices in Australia. With so many options on the market, understanding what drives the cost and how to choose the right battery is essential for making an informed decision.

In this comprehensive guide, Ads Solar, one of Australia’s leading solar retailers and installers, breaks down everything you need to know about solar battery price in Australia in 2025.

What Is a Solar Battery and Why Do You Need One?

A solar battery is an energy storage device that stores excess electricity generated by your solar panels during the day, allowing you to use that stored energy at night or during cloudy days. Essentially, it helps you:

• Reduce your reliance on the grid

• Save on energy bills

• Increase energy independence

• Keep your home powered during outages (if backup power is available)

As electricity prices rise across Australia, solar batteries are becoming increasingly attractive for both residential and commercial users.

How Much Does a Solar Battery Cost in Australia in 2024?

The average solar battery price in Australia in 2025 ranges between $5,000 and $15,000, depending on several factors including battery size, brand, and installation.

Here’s a breakdown of typical prices based on capacity:

Battery Size: Average Price (Installed): Suitable For

5 kWh: $5,000 — $7,000

Small homes: 10 kWh$9,000 — $12,000

Medium to large homes: 13 kWh+$12,000 — $15,000+Large homes / businesses

Note: Prices include installation, inverter (if required), and GST.

Key Factors That Affect Solar Battery Price in Australia

When evaluating solar battery costs, it’s important to consider the factors influencing the price:

1. Battery Capacity (kWh)

The more energy a battery can store, the more expensive it will be. Residential customers generally choose between 5kWh to 13kWh, while commercial setups may need 20kWh or more.

2. Battery Brand

Premium brands like Tesla Powerwall, LG Chem, and Sungrow are generally priced higher due to their advanced technology, longer warranties, and brand reputation.

3. Hybrid vs Retrofit Systems

• Hybrid systems combine solar and battery in a single setup, often reducing costs.

• Retrofit systems add a battery to an existing solar setup and may require additional inverters or upgrades, increasing the overall cost.

4. Battery Chemistry

• Lithium-ion batteries are the most popular due to their efficiency and compact size.

• Lead-acid batteries are cheaper but bulkier and less efficient.

• LFP (Lithium Iron Phosphate) batteries are a newer, safer alternative.

5. Installation Complexity

If your site requires complex electrical work, upgrades, or difficult access, it could raise the total installation cost.

Are Solar Batteries Worth the Investment?

While the upfront solar battery cost can be significant, the long-term benefits often justify the investment. Here’s why:

✔ Lower Electricity Bills

A solar battery allows you to store excess energy instead of exporting it back to the grid at lower feed-in tariffs, meaning more savings.

✔ Greater Energy Independence

Use more of your solar energy and rely less on fluctuating grid prices.

✔ Backup Power

Some solar batteries provide emergency backup power during blackouts — a must-have in many regions of Australia.

✔ Environmental Benefits

Using solar energy stored in batteries reduces reliance on fossil fuels, lowering your carbon footprint.

How Long Does a Solar Battery Last?

Most modern solar batteries come with a 10-year warranty and last between 10–15 years, depending on usage and maintenance.

The total cycles (number of charge/discharge events) also impacts lifespan. A battery with 6,000 cycles at one cycle per day could last over 16 years.

What’s the Payback Period?

The solar battery payback period in Australia typically ranges from 7 to 12 years, depending on:

• Your energy consumption habits

• Solar system size

• Electricity rates in your area

• Feed-in tariffs

• Whether backup power is valuable to you

Batteries generally offer quicker payback when:

• You use most of your energy in the evening

• You are on a time-of-use tariff

• You experience frequent blackouts
