If you’re thinking of buying a solar battery for your home, you might be wondering how much it will cost and what size you need. In this educational blog post, we’ll give you some guidance on how to compare solar battery prices and sizes in Australia based on battery capacity, brand, and the state in which you live.
Solar battery prices vary depending on the storage capacity, which is measured in kilowatt-hours (kWh). The more kWh a battery can store, the more electricity it can provide for your home when the sun is not shining. The average solar battery price in Australia is approximately $1,240 (source) per kWh of storage, excluding installation costs. This means that a 6kWh battery would cost around $7,440, plus install. Tesla’s Powerwall 2 costs around $13,500 for a 13.5 kWh battery ($1000 AUD per kwh), while SunGrow’s SBR096 costs around $9,000 for a 9.6 kWh battery (about $950AUD per kwh).

However, the solar battery price also depends on the brand and model of the battery. Some brands, such as Tesla, LG Chem, and Sonnen, are more expensive than others, such as SunGrow and Growatt. Several factors are at play in this pretty new market.
- Brand
- Intelligence of Software
- Quality of components
- Inbuilt inverter (tesla)
- Warranty period
- Who you buy your solar system from
You should compare different brands and models to find the one that suits your needs and budget.
Some of our batteries offer a cost of approximately $299.80 AUD per kwh. Such as the our Lifepro 15kwh off grid battery which starts at $4999!
It has the option to select the warranty period. Which is a really nice feature for those who may want to save as much as possible.
A second and not well-known factor is that most Solar companies in Australia purposely choose particular models, so that you have almost no flexibility in choosing a battery. This is a walled garden approach, this allows most solar companies, to sell you what they want, and nothing else. It’s very anti-competitive and very much about profit margins for the owners and salespeople of these companies.
Another factor that affects the solar battery price is the state where you live. Some states, such as South Australia and Victoria, did offer rebates and incentives for installing solar batteries, which can reduce the upfront cost significantly. Other states, such as Queensland and New South Wales, have higher electricity prices, which can increase the savings from using a solar battery. You should check the eligibility criteria and availability of rebates and incentives in your state before buying a solar battery.
Performance: The performance of a solar battery depends on its efficiency, depth of discharge (DoD), cycle life, and backup capability. Efficiency is how much energy the battery can deliver compared to how much energy it receives from the solar panels. The higher the efficiency, the less energy is wasted during charging and discharging. Depth of discharge is how much of the battery’s capacity can be used before it needs to be recharged. The higher the DoD, the more energy you can use from the battery. Cycle life is how many times the battery can be fully charged and discharged before its capacity drops below a certain level. The longer the cycle life, the longer the battery will last. Backup capability is whether the battery can provide power to your home during a blackout or when the grid is down. Not all batteries have this feature, so you should check if this is important to you.
To sum up, solar battery prices and sizes in Australia depend on several factors, such as storage capacity, brand, model, and state. You should do your research and compare different options to find the best solar battery for your home.
