A solar battery allows you to store the excess electricity your solar panels produce during the day and use it later — at night, during peak electricity pricing, or when the grid goes down.
At OZ Solar Energy Solutions, we deliver intelligent battery storage solutions that help Australian homes and businesses achieve greater energy independence, maximise savings, and enjoy reliable power around the clock.
Without a battery, unused solar energy is sent back to the grid at low feed-in rates. With battery storage, you keep that power for yourself and use it when electricity prices are highest.
Modern solar and battery systems enhance the appeal and value of your property.
Reduce exposure to increasing electricity tariffs and enjoy predictable energy costs for years to come.
Store excess solar power and use it during evenings when electricity prices are highest.
Generate, store and consume your own electricity while reducing dependence on the power grid.
Keep essential appliances operating during blackouts with selected backup battery systems.
Increase your self-consumption and reduce the amount of electricity exported at low feed-in rates.
Use more renewable energy and contribute to a cleaner, greener Australia.
Monitor your battery performance anytime using intelligent mobile apps and online monitoring.
Clean Energy + Maximum Savings
Store clean energy instead of exporting it back to the grid at low feed-in rates and get more value from every ray of sunshine.
Your solar battery works automatically in the background — storing extra solar energy during the day and using it when your home or business needs it most.
Your solar panels generate electricity throughout the day.
Your home or business uses the energy it needs immediately.
Excess electricity is automatically stored in your battery.
When the sun goes down, your battery supplies stored electricity.
Only when the battery is depleted does electricity come from the grid.
Once installed, your battery system automatically manages solar generation, storage, usage, and grid backup helping you maximise your energy savings without extra effort.
Solar batteries are an excellent solution for homeowners, businesses, and rural properties looking to reduce energy costs, improve reliability, and gain greater control over their power.
Ideal for families and households that want to use more of their own solar energy and reduce grid reliance.

OZ Solar can assess your property, energy usage, and goals to recommend the right battery storage solution for your needs.
Battery systems are becoming increasingly affordable thanks to government incentives and financing options. Depending on your location, you may be eligible for rebates, finance support, and programs designed to reduce your upfront investment.
Our experienced consultants will identify every available rebate and incentive to help minimise your investment and make battery storage a smarter financial decision.
Available Support
OZ Solar helps you understand which incentives may apply to your home or business.
Government incentives are subject to eligibility criteria and may change over time.
WA homeowners can now stack two government rebates — then cover the rest with a 0% interest loan. No catch, no fine print.
Perth Metro
Combined saving for Synergy customers.
Regional WA
Combined saving for Horizon Power customers.
Interest-Free Loan
Available to eligible households.
The WA Government and Federal Government each offer a battery rebate — and you claim both. Your installer applies them automatically, so the saving comes straight off your invoice.
| Rebate Type |
Synergy Customers Perth Metro |
Horizon Power Customers Regional WA |
|---|---|---|
| WA State Rebate | $1,300 ($130/kWh) | $3,800 ($380/kWh) |
| Federal Rebate | $3,720 (~$372/kWh) | $3,720 (~$372/kWh) |
| Total Combined | ~$5,000 on a 10 kWh battery | ~$7,500 on a 10 kWh battery |

After your rebate, eligible households can borrow up to $10,000 at zero interest to cover the remaining battery cost.
A $10,000 loan repaid over 10 years works out to around $19 a week.
Available Loan Support
Eligible WA households may use the interest-free loan to reduce the remaining upfront battery cost after rebates are applied.
Most WA homeowners qualify. Renters are also eligible with written landlord consent. Here’s the quick checklist.
Aged 18 or older and an Australian permanent resident
Current Synergy or Horizon Power customer
Residential home in Western Australia
Owner-occupied or rented with written landlord consent
Reliable internet connection
Brand new — usable capacity between 5 kWh and 10 kWh
On the Clean Energy Council approved product list
Installed on or after 1 July 2025
SAA-accredited and listed on the Plenti Vendor Directory
Your installer submits the rebate you do not apply directly
VPP participation is mandatory to receive the rebate — but it is also an ongoing earning opportunity, not just a condition.
A VPP links thousands of home batteries together into one large, flexible power source. During peak grid demand, a small amount of your stored energy may be used to support the network. In return, you get paid.
Synergy Battery Rewards
Earn 70c per kWh every time Synergy draws on your battery during a peak event.
Helps stabilise the WA grid and reduce the risk of blackouts.
Long-term, VPPs can help reduce electricity price inflation for everyone.
The VPP agreement is only 2 years — you can opt out after that, anytime.
Rebates are open now on a first-come, first-served basis. Federal rebate rates step down each year — the sooner you act, the more you save.
