The Price of Solar Batteries In Sydney: The Cost Of Installing Tesla Powerwall Battery Storage
Solar storage has taken off over the last 2 years, to the point where we are now installing nearly all of our systems with either integrated battery storage or as a battery ready solar system. With battery prices expected to rise again this summer, now is a great time to be getting storage.
The price of solar batteries in Sydney depends mainly on how much capacity you want and what features you need. Read on to learn more about the variables and costs.

The Price of Solar Battery Storage In Sydney: The Cost Of Installing Solar Battery Storage
The price of solar battery storage in Sydney depends mainly on how much capacity you want as well as any additional features such as backup for when the grid is down.
There are lots of options out there in Australia for battery storage, so it can be hard to determine which product is right for you.
For most people, what they really want to know is the ballpark price, before they even get into the conversation around features, benefits and potential savings.
So let’s take a quick look at the price range for a few of the batteries on the market today:
Battery | Size | Indicative Price Range ($AUD) | Notes |
Tesla Powerwall 2 | 13.5kWh | $14,500 - $15,000* | Advanced safety features & seamless blackout protection. |
Enphase IQ Battery | 10kWh | $16,000 | To be released in July 2023 |
SolarEdge Energy Bank | 10kWh | From $12,000 | Additional cost for backup functionality. |
SonnenBatterie | 10kWh | From $14,000 | Integrated backup. |
Sungrow SBR HV | 9.6kWh | $12,000 | Only compatible with Sungrow hybrid inverters |
Enphase IQ Battery | 5kWh | $9,990 | To be released in July 2023 |
Alpha ESS SMILE5 | 5.5kWh | $8,500 - $9,000 | Only 5 year product warranty and limited operating temperature range. |
LG Chem RESU | 6.5kWh | $8,000 - $10,000 | Compatible with select range of hybrid inverters. |
Households with lower energy usage and a solar system smaller than 5kW are often well suited to Enphase batteries. Enphase is soon releasing a new battery, so for anyone looking for a smaller battery solution we recommend waiting for Enphase to be available in Australia in 2023.
Smaller battery systems are designed to store power during the day to use in the evening, and typically don’t include backup functionality.
For households with at least a 5kW solar system, Powerwall from Tesla will be a better fit. Though already available for as much as $19,000, and with prices expected to increase again this summer, the cost of installing a Tesla Powerwall as an addition to your solar panels is currently $14,500 to $15,000 fully installed with Solaray, or around $175 a fortnight over 5 years.
Remember, solar battery storage captures excess solar power so you should be generating at least 8-13 kWh of excess solar power a day to charge a larger solar battery. Larger solar batteries are ideal for maximising self-sufficiency, reducing your household’s reliance on coal & gas, protecting your home when the grid goes down and aiming to run your home on solar power 24/7.
Smart Solar Storage Systems
Electricity prices are skyrocketing. Battery storage allows you to maximise your self-sufficiency and run your home on solar 24 hours a day.
Tesla Powerwall is a smart home battery that integrates with your existing solar system. We will help you reduce your power bills and even backup your home in the event of a blackout.

Living Without Power Bills
Solaray customer Angela has been living easy now that powering her home is entirely free.
For the last year, Angela’s home has been 96% powered by solar panels and a Solaray Energy installed Tesla Powerwall home battery.
Powering the home in 2018 used to cost Angela $2400, but in the months after combining her solar panels with a new Tesla Powerwall home battery, Angela’s power bill has dropped to below $0. This means her power retailer is, in fact, giving her a credit every quarter for the energy she’s contributed back to the grid.
“My power bill used to be $600 per quarter, the last bill I got was a credit of $40. I’m sure the next bill will be even better since it’s summer.” Read Angela’s story here…
Angela’s story isn’t unique either. We are getting a lot of feedback from our customers that they are now living with very small power bills, or who are even in credit.

How Solar Storage Reduces Your Power Bills
The feed-in tariff for selling excess solar power back to the grid is very low in many states of Australia. In Australia, we typically get a credit on our power bill of between around 10 and 12 cents a kWh. By storing this excess solar power in batteries, we can use it during the peak billing period where prices can be over 50 cents a kWh. This is known as maximising self-consumption of solar power and is a great way to reduce your power bill. Many Solaray customers are now running their home almost entirely on solar power!
Energy prices continue to rise. Even if you get a discount from your energy retailer, power prices in Australia are amounts the highest in the developed world, in some cases more than double the price for energy compared to nations such as Sweden and Finland. Nationally, prices are up more than 120% over the last 10 years, and this trend is expected to continue for the foreseeable future. By installing solar with battery storage you can lock in your power prices for the next 25 years by generating most of your own power using solar (Rolfe 2016).
Australia is still mainly powered by coal. Australian households are leading the world with our uptake of residential solar power with 1.5 million systems installed, however the same cannot be said for government and big business. Most of the power generated in Australia still comes from coal, and there is reluctance in Canberra to transition to renewables. The biggest vote we have as consumers is to lead the way, installing solar power with backup storage to run our homes almost entirely on solar power. By installing a 5kW system, we take around $50,000 off the books of the coal industry and directly invest in the growing renewables industry.
Solar storage systems include revolutionary energy management technology that automatically directs solar power into your home or to recharge your batteries. Online consumption monitoring allows you to monitor how much power you are using in the home as well as how much solar power your system is generating.
Exciting home automation is on the way, which will allow you to send excess solar power into appliances such as to automatically turn on the pool pumps, air conditioner or underfloor heating. All of this will be able to be controlled from a mobile phone, allowing you to take back control of your power consumption.
EV charging is around the corner. Installing a solar power system will allow you to charge your electric car from excess solar power, and it may even allow you to charge your home batteries from excess capacity in the car’s battery.
The power grid is struggling to generate enough capacity on hot days, causing highly-publicised and disruptive blackouts in SA and around Australia. By installing solar storage, you can continue to run essential appliances such as your freezer, the internet and perhaps a few lights.
