Home solar battery storage has come a long way since it first burst onto the scene. What was once a product reserved for tech/eco-enthusiasts with deep pockets is increasingly becoming an attractive option for everyday homeowners looking to push their solar savings further by using more of the energy their panels produce.
Thanks to many innovators (some who’ve now got their sights set on Mars), the solar battery price in Australia has plummeted. Supply chain issues due to COVID have definitely curbed that trend recently, but as the world emerges from lockdowns, the solar battery price has started to decline once again.
Thanks to this steady downtick in solar battery storage price Australia can expect increased adoption in the coming years. Don’t be surprised if you see –
- Faster payback periods
- More competition in the market
- More installers offering solar battery storage
If you’re thinking of buying a solar battery price will be your main concern, so let’s look at what you can expect to pay based on battery size.
What is the average solar battery price in Australia?
Today, the solar panel battery price Australians pay is approximately $1,390 per kWh of storage.
This means if you were looking at a 6kWh solar battery price guides would put it around $8,340, including install.
After a different size? Check out our estimated solar battery cost table below!
| Battery Size | Solar Battery Price* |
| 13kWh solar battery price | $18,070 |
| 10kWh solar battery price | $13,900 |
| 9kWh solar battery price | $12,510 |
| 8kWh solar battery price | $11,120 |
| 7kWh solar battery price | $9,730 |
| 6kWh solar battery price | $8,340 |
| 5kWh solar battery price | $6,950 |
*Including installation cost
A 13kWh battery (or thereabouts) is the most popular choice for Australians looking to maximise their solar system as a battery this size could power your home for hours.
As we can see from the table below, the most installed batteries in Australia today are around 10kWh for this reason:
| Battery | Nominal Capacity | |
 | LG Chem RESU 10 | 9.86 kWh |
 | Redback SB9600 | 9.6 kWh |
 | sonnenBatterie Hybrid 9.53/10 | 10.0 kWh |
 | Senec.HOME V3 Hybrid | 10 kWh |
 | SunGrow SBR096 | 9.6 kWh |
 | Eguana Evolve 0513 | 13 kWh |
 | Tesla Powerwall 2 | 13.5 kWh |
 | Goodwe Lynx Home U Series | 4.8 kWh – 28.8 kWh |
 | Goodwe Lynx Home F Series | 6.55 kWh – 16.38 kWh |
 | QCells Q.HOME CORE H5S | 6.8 kWh – 20.5 kWh |
| Battery LG Chem RESU 10 Nominal Capacity 9.86 kWh |
| Battery Redback SB9600 Nominal Capacity 9.6 kWh |
| Battery sonnenBatterie Hybrid 9.53/10 Nominal Capacity 10.0 kWh |
| Battery Senec.HOME V3 Hybrid Nominal Capacity 10 kWh |
| Battery SunGrow SBR096 Nominal Capacity 9.6 kWh |

| Battery Tesla Powerwall 2 Nominal Capacity 13.5 kWh |
| Battery Goodwe Lynx Home U Series Nominal Capacity 4.8 kWh – 28.8 kWh |
| Battery Goodwe Lynx Home F Series Nominal Capacity 6.55 kWh – 16.38 kWh |
| Battery QCells Q.HOME CORE H5S Nominal Capacity 6.8 kWh – 20.5 kWh |
Do brands affect solar battery cost in Australia?
The Ferrari horse bumps up the price of their products, as does Nike’s tick. It turns out solar is no different.
When you’re looking to purchase a solar panel battery price is strongly linked with brand, with prestige products like the Tesla Powerwall 2 costing you more out of the box.
But that’s not to say a Tesla Powerwall 2 isn’t worth the money. It’s a solid option, including the fact that it comes with excellent after purchase support which is a super important factor to consider when buying a solar battery. They are industry-leading batteries for a reason.
If all you care about is utility then there are still plenty of budget conscious options that deliver. Take SunGrow for example. Based in China, their overheads are much less, meaning they can keep their solar battery price lower than their competitors, despite still offering excellent quality.
All this said, the only way to get accurate solar battery prices is by talking to an expert solar battery installer. Get 3 free solar & battery quotes from expert installers.
When it comes to solar battery pricing, Australia isn’t a level playing field…
Solar battery cost does vary in Australia from state to state, mainly due to the subsidies and incentives offered by some state governments. For all the up to date information on current solar battery rebates available in your state or territory, visit our dedicated battery rebates page here.
How solar battery sizing (kW / kWh) actually works
Solar batteries come with both a kilowatt hour (kWh) and kilowatt (kW) rating. Think of these as the MAXIMUM AMOUNT of energy (kWh) a battery can store and the MAXIMUM SPEED that it can discharge that energy to run your home respectively.
A lot of people get confused by this so let’s look at an example.
If you had a solar battery that was rated 5kW / 10kWh, you could assume:
- The max power it can discharge at any one time is 5kW
- If the battery was fully charged you could draw that 5kW for 2 hours before you deplete your battery
10kWh / 5kW = 2 hours of full usage.
You can never draw more power from your battery than it’s kW rating, that’s as fast as it goes!
Be careful, if you run multiple appliances that push your consumption needs higher than your battery’s kW rating then you’ll start drawing any excess from the grid.

Will a 5kWh vs 5kW solar battery price be different?
Yes. As discussed above, 5kW and 5kWh are actually different measurements altogether. Your solar battery’s energy storage capacity is measured in kWh (kilowatt-hour) while its power is measured in kW (kilowatts).
The difference?
- Its power (kW) is the rate at which it can charge or discharge
- Its storage capacity is the amount of energy it can hold
In both cases bigger isn’t always better. There’s no point paying for a higher power system (kW) if it’s more than your home and appliances can draw. Equally, there’s no point forking out for additional capacity (kWh) that you aren’t going to use.
Therefore a 5kW and 5kWh battery will likely not be the same price, you’re comparing apples and oranges.
The question you should be asking is, ‘What’s the difference between 5kW and 6kW solar battery price?’
And remember, you need both kW and kWh specifications to get an accurate quote on a battery.
Is the solar battery price in Australia going down?
Yep! As demand for affordable home batteries continues to grow across Australia and the world, manufacturing efficiencies and competition is only getting more fierce — which is great for us consumers.
The last 10 years saw staggering mass adoption of rooftop solar across Australia as technology advanced, the market matured and prices tumbled. The same has and continues to happen with solar batteries.
The benefits plus economics of installing a solar battery has become viable for many Australian homes already. To find out if the payback period and cost of a solar battery is now viable for your home, the best thing to do is to get a tailored quote based on your home’s energy profile.
Can I add a solar battery to my existing solar system?
Yes – but you may need to change your inverter. Hybrid inverters allow you to add batteries to your existing systems by connecting them to the grid. Alternatively you may need to add a battery inverter instead. Get 3 quotes from qualified installers to assess your situation.
