WA Solar Battery Rebate

The WA Battery Rebate Program has been designed with three primary objectives:

1. Reduce household electricity bills by allowing homeowners to store excess solar energy and use it during peak periods when electricity prices are highest.

1. Stabilise the electrical grid by creating a network of distributed energy resources that can help balance supply and demand, particularly during periods of high stress on the system.

1. Support renewable energy adoption by making battery storage more affordable, thereby encouraging more households to maximise their solar investment.

For Perth homeowners, this represents a unique opportunity to future-proof their homes while significantly reducing long-term energy costs.

Western Australia's battery rebate program offers several advantages compared to similar initiatives in other states:

The WA scheme stands out for its generous rebate amounts and the addition of interest-free loans, making it one of Australia's most comprehensive battery support programs.

The rebate amount is calculated based on your battery's storage capacity (measured in kilowatt-hours or kWh) and your electricity provider:

• Synergy/Western Power customers: $500 per kWh of storage capacity
• Horizon Power customers: $750 per kWh of storage capacity



Both rebate structures are capped at a maximum of 10kWh, meaning the maximum possible rebates are:

• Up to $5,000 for Synergy customers
• Up to $7,500 for Horizon Power customers

This tiered approach recognises the higher costs and greater grid benefits of battery installation in regional areas served by Horizon Power.

While the program aims to support 20,000-30,000 households across Western Australia, it's important to note that this represents only a small percentage of eligible properties. With approximately 900,000 dwellings in Western Australia, the limited availability of rebates means that early preparation and prompt application will be crucial.

At Perth Solar Direct, we're already helping customers prepare for this program by installing solar systems with battery-ready inverters, ensuring they'll be positioned to quickly add storage once rebates become available.

The WA government is offering means-tested interest-free loans of up to $10,000 to eligible households. These loans feature:

• Zero interest for the entire repayment period

• 10-year repayment terms, providing manageable monthly payments

• Minimum loan amount of $2,000, ensuring the administrative costs of the program are justified

• No early repayment penalties, allowing households to pay off their systems faster if desired

This financing option represents a significant opportunity for households that might otherwise struggle with the upfront costs of battery installation, even after applying the rebate.

A particularly valuable aspect of the loan program is that it can be used to fund both battery storage systems and new solar panel installations when installed together. This creates an excellent opportunity for households that:

• Don't yet have solar panels installed

• Have older, smaller solar systems that would benefit from an upgrade before adding battery storage



• Want to maximize their renewable energy capacity in a single installation

This provision recognizes that battery storage delivers maximum value when paired with appropriately sized solar generation.

All battery systems must meet these technical specifications:

• Minimum storage capacity of 5kWh, ensuring meaningful energy storage capabilities

• Virtual Power Plant (VPP) readiness, allowing the battery to participate in grid support programs

• Ongoing internet connection with regular testing to enable monitoring and VPP participation

• Compliance with Australian standards including AS/NZS 5139:2019 for battery installations



• Compatibility with local grid requirements from Western Power or Horizon Power

These requirements ensure that subsidized battery systems will contribute to grid stability while providing reliable service to homeowners.

The rebate program has specific requirements regarding property ownership:



• Primary residences are eligible (owner-occupied homes)
• Investment properties may be eligible with additional documentation
• Rental properties qualify when the landlord applies and meets tenancy agreement requirements
• New builds are eligible if completed and occupied before application

1.Pre-qualification check: Determine your eligibility based on property type, location, and existing solar system.

2. System selection: Choose an eligible battery system and approved installer (like Perth Solar Direct).

3. Quote preparation: Receive a detailed quote specifying the battery system, capacity, and total costs.

4. Application submission: Complete the online application form through the WA government portal, including your property details, system specifications, and installer information.

5. Rebate approval: Receive confirmation of your rebate reservation and approval amount.

6. Installation: Schedule and complete your battery installation with your chosen provider.

7. Post-installation verification: Submit proof of installation and system compliance.

8. Rebate payment: Receive the rebate payment directly or as a discount on your installation.

The WA Residential Battery Scheme will operate on a first-in-first-served basis until all allocated rebates are distributed. Based on the experience of similar programs in other states, we anticipate:

• High initial demand with potential for early allocation of available rebates

• Application processing times of approximately 2-4 weeks

• Installation window requirements mandating completion within a specific timeframe after approval
