Solar Battery Rebates in Perth, WA: A Complete Homeowner’s Guide

Adding a battery to your solar system in Perth is no longer just about energy independence, it is increasingly about making the most of available rebates and support programs. Western Australia currently offers a combination of state and federal incentives that can significantly reduce the upfront cost of battery storage.

These programs are designed to help households store excess solar energy, reduce reliance on the grid, and manage rising electricity costs more effectively. However, understanding how each scheme works, what you are eligible for, and how to apply is essential if you want to get the full benefit. This guide breaks down the key programs, requirements, and processes in detail.

WA Residential Battery Scheme

The WA Residential Battery Scheme was introduced as part of a broader government initiative to make battery storage more accessible for households. The program represents a substantial investment, with funding allocated to support rebates and financing options for eligible homeowners.

Under this scheme, households can access a rebate that directly reduces the cost of installing a battery system. The total benefit becomes more significant when combined with federal support, allowing households to reduce upfront expenses and improve long-term savings.

One of the key considerations is availability. With a large number of existing solar installations across Western Australia, demand for battery rebates is expected to be high. Since the program is capped, not every household may be able to access it indefinitely.

Rebate structure

The rebate is calculated based on the usable capacity of the battery and is capped at 10 kWh. The amount you receive depends on your electricity provider:

  • Synergy customers: $130 per kWh, up to a maximum of $1,300 for a 10 kWh battery
  • Horizon Power customers: $380 per kWh, up to a maximum of $3,800 for a 10 kWh battery

Eligibility Criteria

Eligibility is divided into clear categories covering the applicant, property, system requirements, and participation conditions.

1. Who can apply (applicant)

To be eligible, you must:

  • Be a permanent resident of Australia
  • Be 18 years of age or older
  • Be a customer of either Synergy or Horizon Power

For those applying for the optional loan, an additional requirement applies:

  • Household gross annual income must be below $210,000 (this is verified during the application process)

2. Property rules (homes)

The scheme applies to residential properties within Western Australia. Eligible scenarios include:

  • Residential homes located in WA
  • Owner-occupied properties
  • Some rental arrangements, provided the necessary approvals between owner and tenant are in place

Common property disqualifiers to watch for

Certain property types or arrangements may not qualify:

  • Non-residential buildings
  • Properties owned by excluded entity types (such as specific government or institutional ownership categories)
  • Apartments or strata properties connected through embedded electricity networks, where eligibility depends on how electricity is metered and billed

3. Battery and inverter rules (product eligibility)

To qualify under the scheme, the system itself must meet minimum requirements:

  • The battery must be new and provide at least 5 kWh of usable capacity
  • Both the battery and inverter must appear on approved product lists relevant to your provider (such as Synergy or Horizon Power supported solutions)
  • All components must meet applicable technical standards and comply with required product certifications

4. VPP participation requirement

Participation in a Virtual Power Plant (VPP) is mandatory to access the rebate or the associated loan.

This means your battery system must be connected to a program that allows coordination with the broader electricity network.

How to Apply (Current Process)

The application process is structured and typically handled through approved vendors rather than directly by homeowners.

Step 1: Confirm eligibility

Start by identifying your electricity provider (Synergy or Horizon Power), confirming your property type, and ensuring you are willing to participate in a VPP.

Step 2: Choose an accredited vendor

Applications must be submitted through approved vendors. Homeowners do not lodge rebate applications themselves.

Step 3: Select approved products

Your chosen vendor will ensure that the battery and inverter meet the required standards and are listed as eligible products.

Step 4: Application submission

The vendor submits the rebate application on your behalf.
If you are applying for the loan, the financing provider will contact you separately to complete income verification and credit checks.

Step 5: Installation and connection

Once approved, installation and system connection take place, including VPP setup.
There are timing and compliance requirements, so installation should proceed promptly after approval rather than being delayed.

Program duration and availability

The scheme is expected to remain available until the allocated number of rebates, up to 100,000, has been fully distributed. Availability may change depending on demand, so checking current status before proceeding is important.

Cheaper Home Batteries Program

This is a national initiative designed to make battery storage more affordable for households and small businesses. It operates alongside state-level incentives and provides additional financial support.

The Cheaper Home Batteries Program offers an upfront reduction in the cost of eligible battery systems, typically around 30 percent. This support is delivered through the Small-scale Renewable Energy Scheme and administered by the Clean Energy Regulator.

The broader goal is to support better use of solar energy, reduce dependence on traditional generation sources, and improve long-term energy affordability.

Program objectives

  • Enable households to store and use more of their own solar energy
  • Reduce reliance on grid electricity and high-cost generation
  • Support long-term reductions in energy costs

Eligible Battery Systems

Minimum and maximum battery size

To qualify:

  • The system must have a nominal capacity between 5 kWh and 100 kWh
  • The discount applies to up to 50 kWh of usable capacity
  • Electric vehicles are not considered eligible under this program

Battery system composition

Eligible systems must meet Australian standards and can be configured in different ways:

  • A single integrated battery unit, or
  • A modular system made up of multiple battery units operating together

Additional capacity may qualify if:

  • The existing system has not previously received a discount
  • The added capacity is at least 5 kWh
  • The total system size does not exceed 100 kWh

If a system has already received a discount, further additions are not eligible.

Accreditation of battery systems

Both the battery and its inverter must be listed on the Clean Energy Council approved product list.

On-grid and off-grid systems

Eligible systems can be installed in different configurations:

  • On-grid systems connect to the electricity network
  • Off-grid systems are located away from network access, either at least one kilometre from a grid line or where connection costs exceed $30,000

VPP capability

Requirements differ depending on system type:

  • On-grid batteries must be capable of participating in a Virtual Power Plant
  • This includes the ability to connect to the grid and respond to signals from third-party operators
  • An active internet connection is required
  • Participation is not mandatory, only capability
  • Off-grid systems are not required to have VPP capability

How to Access the Battery Discount

Homeowners do not apply directly to the Clean Energy Regulator. Instead, there are two available pathways.

Through accredited installers or retailers

  • Contact an accredited installer or battery retailer
  • The discount is typically applied upfront or provided after installation
  • The installer manages the administrative process
  • Any concerns about the discount can be directed to the regulator

Applying directly through the REC Registry

  • You can choose to manage the process yourself by creating and trading Small-scale Technology Certificates (STCs)
  • This requires registering and operating through the REC Registry
  • To do this, you must not assign the right to create STCs to your installer
  • STCs can be traded via the Clearing House or open market
  • Further guidance is available through official resources on creating and selling certificates

Interest-Free Solar Battery Loans (Optional)

In addition to rebates, eligible households may access a no-interest loan to help manage upfront costs.

Key features include:

  • Loan amounts ranging from $2,001 to $10,000
  • Repayment terms between 3 and 10 years
  • Zero percent interest

Eligibility is means-tested:

  • Available to households with a combined annual income below $210,000
  • Limited number of loans available

What the loan can cover:

The loan can be used not only for the battery itself but also for related equipment installed as part of the system, including:

  • Inverters
  • New solar panels
  • Replacement or upgraded components

All equipment must be installed as part of a battery package under the scheme.

Solar Battery Rebate Changes in May: Why Acting Early Matter

From 1 May 2026, two important updates begin affecting how solar battery systems are installed and how rebates are calculated. The federal rebate under the Cheaper Home Batteries Program shifts from a flat structure to a tiered model, meaning larger battery systems will receive a reduced benefit on capacity above certain thresholds.

At the same time, new grid connection requirements come into effect across Western Australia, introducing additional technical considerations for new and upgraded systems.

Together, these changes reduce the overall value available for some installations and add complexity to the process. For homeowners considering battery storage, acting before the May deadline is the simplest way to secure the current rebate structure and avoid the added constraints that come with the updated rules.
