Can I Get the Battery Rebate if I Already Have Solar Panels?
The short answer? Yes, you absolutely can. If you’ve already installed a solar system on your property, you’re still eligible to claim the battery rebate under various federal and state programs in Australia. In fact, adding a home battery to your existing solar panels can be one of the most cost-effective upgrades for reducing your electricity bills and boosting your renewable energy usage.
This article provides a complete, step-by-step explanation of the solar battery rebate programs available to Australians in 2025, how to determine your eligibility, and what you need to know before installing a battery alongside your existing solar system. Whether you’re a homeowner looking to improve energy independence or simply reduce energy costs, this guide covers everything you need to know.
Understanding the Solar Battery Rebate in Australia
The battery rebate in Australia is part of a growing network of government battery incentive schemes designed to support the adoption of home battery systems and reduce household reliance on the grid. These include both federal and state-level programs.
The federal government solar battery rebate (officially known as the Cheaper Home Batteries Program) is expected to launch by 1 July 2025, offering up to a 30% upfront discount on eligible battery installations.
Additionally, rebates and interest-free loans are available in several states like Victoria (Solar Victoria), WA, QLD, and TAS, encouraging the pairing of batteries with new or existing rooftop solar systems.
Am I Eligible for a Battery Rebate If I Already Have Solar?
Yes, if you already have solar panels, you’re still eligible for the solar battery rebate in most programs.
Here’s what you typically need:
- A functioning solar system already installed on your property
- The ability to install an approved battery system by an accredited installer
- A battery that meets the technical requirements of the government battery rebate program
Some rebate programs may have additional requirements such as:
- Meeting household income caps (for some state-based loans or grants)
- Ensuring your solar and battery system is connected to an eligible inverter
- Installing a battery that supports virtual power plant (VPP) participation
It’s important to review the specific eligibility terms for your state or territory and consult an accredited installer for a tailored quote.
What Is the Federal Government Offering in 2025?
The federal government solar battery rebate launching in July 2025 is part of a $2.3 billion investment to encourage battery storage across the country.
Here are the highlights:
- 30% rebate on battery installation costs
- Applies to new battery installations — including homes that already have solar panels
- Open to households and small businesses
- Delivered through certified installers approved under the Clean Energy Council
This new government program is expected to make home battery systems more accessible and reduce the upfront cost of adding storage.
What About the Solar Victoria Battery Program?
Solar Victoria continues to offer a home battery rebate for eligible households in the state.
Key features include:
- Up to $2,950 in rebates for battery installation
- Can be paired with existing solar systems
- Must use an approved installer and battery system
- May be combined with an interest-free loan depending on income and property
You can check your eligibility on the Solar Victoria website or by using their online calculator to estimate rebate value and battery size.
What Is the Cost of Installing a Battery with Existing Solar?
The cost of installing a battery with an existing system will vary based on:
- Battery size (kWh capacity)
- System type (hybrid vs AC-coupled)
- Compatibility with your current solar system
- Choice of installer and brand
Typically, a battery system will cost between $6,000 and $15,000 before rebates. With a 30% government rebate, that could reduce your upfront cost by thousands.
Be sure to get a quote from multiple installers to compare options and assess what rebate you can access.
Step-by-Step Guide to Adding a Battery and Claiming the Rebate
Here’s your step-by-step guide to claim a solar battery rebate if you already have panels installed:
1. Assess Your Existing Solar System
Ensure your system is compatible with adding a battery. Your inverter type and system age will determine if upgrades are needed.
2. Use a Battery Calculator
Try an online battery calculator to estimate your required battery capacity and potential savings.
3. Check Your Rebate Eligibility
Visit the solar battery rebate program page for your state and the federal government portal (when available in July 2025).
4. Get Quotes from Accredited Installers
Only use Clean Energy Council-approved installers who can confirm your rebate eligibility and assist with paperwork.
5. Apply for the Rebate or Loan
Submit your application with all required documentation. Some rebates are rebate with the federal, while others come as a discount through your installer.
6. Proceed with Battery Installation
Schedule your battery installation and ensure the system is compliant with safety and grid regulations.
Are There Loans for Solar Batteries?
Yes. In addition to rebates, you can access solar battery loan options through:
- State schemes like Solar Victoria’s interest-free loan
- Select banks or green lenders offering loans for solar systems
- Installers offering in-house finance or payment plans
These loans are ideal for households that want to install solar and storage but prefer not to pay the full upfront cost.
How Much Could You Save with a Battery?
Adding battery storage to your solar system helps you:
- Store excess solar energy for use at night
- Reduce demand on the grid
- Lower peak energy costs and lock in long-term savings
Depending on your energy use and battery size, you could save $600–$1,500 per year on electricity bills.
Use a battery calculator to find out how much you could save based on your location, system, and household consumption.
What Types of Batteries Qualify?
To receive the government solar battery rebate, your chosen product must be:
- On the list of solar batteries approved by your state or territory
- Installed by an accredited installer under the small-scale renewable energy scheme
- Integrated safely into your current or upgraded solar system
Speak with your installer about a specific battery that fits your roof space, system, and energy needs.
