What Are Solar Battery Storage Prices in Australia?

Are you considering solar battery technology for your home in Australia? With rising electricity prices and increasing interest in renewable energy, many homeowners are looking to solar battery storage to save money and gain energy independence. This guide covers everything you need to know about solar battery storage prices in Australia, helping you make an informed decision.

The Cost of Solar Battery Storage in Australia

The price of solar battery storage in Australia ranges from $800 per kWh to $2000 per kWh. Several factors influence this price, including the amount of energy you want to store, your location, and any additional features you might need, such as backup power during grid outages.

Basic Costs

  • Small Systems: Starting at around $5,000, you can get a smaller battery system such as an Enphase, which is suitable for homes with moderate energy needs.
  • Large Systems: For larger batteries like the Tesla Powerwall, prices can go up to $18,000 for a fully installed system. These are ideal for homes looking to maximise their solar usage and have backup capabilities.

Factors Influencing the Price

  1. Energy Storage Capacity: The more energy you need to store, the higher the cost. This is typically measured in kilowatt-hours (kWh).
  2. Installation Costs: These can vary based on your location and the complexity of the installation.
  3. Additional Features: Features like backup power during blackouts or advanced home automation can add to the cost but provide significant benefits.

Benefits of Solar Battery Storage

Investing in solar battery storage offers more than just savings on your power bill. Here are some key benefits:

Blackout Protection

During power outages, a solar battery can keep your home running smoothly. Many customers report significant relief and convenience during long blackouts, as their homes remain powered while their neighbours struggle without electricity.

Virtual Power Plants (VPPs)

Some solar batteries allow you to sell excess solar power back to the grid at rates higher than standard feed-in tariffs. This can provide an additional income stream and further reduce your power bills.

Energy Independence

With home battery storage, you can run your home on solar power 24 hours a day. This not only protects you from future electricity price hikes but also reduces your reliance on the grid and fossil fuels.

Electric Vehicle Charging

If you own an electric vehicle (EV), using solar power to charge it can save you money on petrol and further reduce your carbon footprint.

Environmental Impact

By divesting your home from coal and gas, you contribute to a cleaner environment. The intangible benefits of energy independence and environmental stewardship can be significant.

Return on Investment (ROI)

To determine if solar battery storage is worth the investment, consider the following:

  • Energy Savings: Calculate how much you would save annually by using stored solar energy instead of grid electricity. For example, if you save $1,000 per year on your electricity bill, this can help offset the initial cost of the battery over time.
  • Lifespan and Efficiency: Solar system batteries typically have a lifespan of 10 years or more. High-quality batteries may continue to operate beyond this period, albeit with reduced capacity.
  • Financial Incentives: Look for government rebates or incentives that can reduce the upfront cost of solar battery storage.

Example Calculation

Let’s assume you install a 5kWh battery system with an estimated lifetime of 10 years. If you use all 5kWh daily and pay $0.30 per kWh for grid electricity, your annual savings would be around $547.50.

Over 10 years, this adds to $5,475. If the battery system costs $5,000, you would break even in just over nine years. Any savings beyond this point contribute directly to your ROI.

Hidden Costs of Battery Storage

Battery Installation Quality

Choosing a reputable installer is crucial. Poor installation can impact the battery’s lifespan and effectiveness, leading to additional costs down the line. Ensure your installer has a good track record and uses high-quality materials.


Although solar batteries require minimal maintenance, occasional check-ups can ensure optimal performance and longevity.

Leading Solar Battery Storage Options in Australia

Several brands dominate the Australian market, offering reliable and efficient solar battery storage solutions:

Tesla Powerwall

The Tesla Powerwall is one of the most popular options, known for its high capacity (13.5 kWh) and advanced features, including backup power and home automation integration.


Enphase offers smaller, modular battery systems that are ideal for homes with moderate energy needs. These systems start at around $5,000 and can be scaled up as needed.
