Act before 1 May 2026: The Small-scale Technology Certificate (STC) deeming period shortens each year as the scheme steps toward its 2030 end date. From 1 May 2026, the upfront government rebate on new battery and solar installations reduces. Homeowners who install before that date receive the higher current rebate. Install now to lock in the higher rebate before May 2026. Call 1300 717 583 for current pricing.

Australian Government Cheaper Home Batteries Program

The Australian Government announced the Cheaper Home Batteries Program as part of the 2024-25 Federal Budget under the Powering Australia and Future Made in Australia plan. The program provides interest-free loans through the Clean Energy Finance Corporation (CEFC) for eligible households installing approved battery storage systems.

The goal is to reduce battery costs by around 30% and make home battery storage accessible to more Australian families. WA homeowners can potentially stack this with Synergy's Distributed Energy Buyback Scheme (DEBS) (currently 2.5 c/kWh for new connections) for maximum savings on their energy bills.

  • Interest-free loans through the CEFC for approved battery systems
  • Reduces upfront battery costs by up to 30%
  • Stackable with the WA Residential Battery Scheme rebate (up to $5,000)
  • Batteries must be on the Clean Energy Council (CEC) approved product list
  • Installation must be by a CEC approved installer

Approved brands include Tesla Powerwall 3, Sungrow SBR, BYD Battery-Box, and Enphase IQ Battery, among others on the CEC approved product list.

STC Rebate Tiers: How Battery Size Affects Your Rebate

Under the Small-scale Technology Certificate (STC) scheme (see the Clean Energy Regulator's STC guidelines), the rebate factor applied to battery storage systems is tiered by capacity:

Battery Capacity STC Factor
0 to 14 kWh 100% of the STC factor
14 to 28 kWh 60% of the STC factor
28 to 50 kWh 15% of the STC factor

Why 14 kWh Is the Sweet Spot

A battery sized up to 14 kWh receives the full 100% STC factor, meaning you get the maximum upfront rebate per kilowatt-hour of storage. Popular batteries like the Tesla Powerwall 3 (13.5 kWh usable) fall just under this threshold, which is one reason they are so common in Perth homes. Check the CEC approved battery product list for eligible models.

Why 28 kWh Matters for Larger Homes

If you need more than 14 kWh of storage, the capacity between 14 kWh and 28 kWh still attracts 60% of the STC factor. This makes a dual-battery setup (e.g. two 13.5 kWh units totalling 27 kWh) a smart choice for larger homes or households with high overnight energy use: you stay within the 28 kWh threshold where the rebate is still meaningful.

What Changes from 1 May 2026

From 2026, the STC deeming period shortens, reducing the total number of STCs generated for any battery installation. This means the dollar value of all three tiers decreases. Homeowners who install before the May 2026 reduction lock in the higher rebate. For a 14 kWh system at 100% factor, the difference between installing now versus after May 2026 can be several hundred dollars. For a 28 kWh dual system, the saving is even larger.

The key takeaway: Size your battery at 14 kWh or below to maximise the per-kWh rebate. If you need more capacity, staying under 28 kWh keeps you in the 60% tier. Above 28 kWh, the rebate contribution drops sharply to 15%, making very large systems harder to justify on rebate value alone. Call 1300 717 583 to discuss the right size for your Perth home.

Why Are Perth Homeowners Choosing Home Battery Storage in 2026?

Perth has the highest solar generation in Australia, yet with Synergy's DEBS export rate sitting at just 2.5 c/kWh for new connections, exporting excess solar is far less valuable than storing it. A correctly sized battery charges from your panels during the day and powers your home through the evening, dramatically reducing grid electricity bills at Synergy's rising Home Plan A1 rates.

The WA Residential Battery Scheme offers eligible Synergy customers up to $5,000 rebate plus a $10,000 interest-free loan for batteries installed from 1 July 2025. The federal Cheaper Home Batteries Program provides additional subsidy on top. The rebate amount is also influenced by battery capacity tiers under the Clean Energy Regulator's STC guidelines. Batteries must be installed by a CEC approved installer and participation in a Virtual Power Plant (VPP) is required to qualify for the WA rebate.

WA Battery Scheme rebates available now. Ares Energy is CEC approved and AS/NZS 5139 compliant. Check your eligibility today.

Is a Home Battery Worth It for Perth Homeowners in 2026?

Battery systems are not suitable for every household or usage pattern. Factors such as daily energy use, export limits, inverter compatibility, and existing system design all affect whether a battery will deliver meaningful benefits.

We provide clear advice based on your actual system, not assumptions or generic recommendations.

Daily energy usage & export patterns
Inverter compatibility assessment
Existing system design review
Realistic payback expectations

Key Considerations

  • Solar export limits Helps maximise self-consumption
  • Night-time usage profile Battery value depends on evening loads
  • Inverter compatibility Not all inverters support battery addition
  • Electrical safety standards AS/NZS 4777 compliance required

Frequently Asked Questions: Perth Battery Storage

Eligible Synergy customers in Perth can access up to $5,000 rebate plus a $10,000 interest-free loan under the WA Residential Battery Scheme for batteries installed from 1 July 2025. The federal Cheaper Home Batteries Program provides an additional subsidy on top. Your battery must be installed by a CEC approved installer and you must join a Virtual Power Plant (VPP) program.
Yes. To qualify for the WA Residential Battery Scheme rebate, your battery must be enrolled in an approved VPP program. This allows your battery to support the grid during peak demand periods. Ares Energy can advise on approved VPP providers available to Perth homeowners. For further details, see the Consumer Protection WA guide to the battery scheme.
Not all inverters support battery storage addition. Compatibility depends on the inverter model, firmware version, and communication capability. Ares Energy performs a thorough inverter compatibility assessment before recommending any battery, checking at the firmware, communication protocol, and electrical protection level. We only recommend a battery if it is genuinely compatible with your existing system.
Ares Energy has hands-on experience with all major battery brands used in Perth homes, including Tesla Powerwall 3, Sungrow SBR, Sigenergy, and Alpha-ESS. We also diagnose and service battery systems originally installed by other providers, regardless of brand.
No. Batteries installed before 1 July 2025 are not eligible for the WA Residential Battery Scheme rebate. Only new installations completed from that date onwards by a CEC approved installer are eligible, provided all other scheme conditions are met including VPP enrolment.
All residential battery storage systems in Perth must comply with AS/NZS 5139 (Battery Energy Storage Systems for Dwellings), AS/NZS 4777 (Grid Connection of Energy Systems), and AS/NZS 3000 (Australian Wiring Rules). Ares Energy installs to all current Australian standards, and a Certificate of Electrical Compliance is provided on every installation.
Payback periods vary based on battery size, your solar system output, evening energy usage, and applicable rebates. Perth's high solar generation combined with Synergy's very low DEBS export rate (2.5 c/kWh for new connections) makes battery self-consumption highly valuable compared to exporting. With the WA Residential Battery Scheme rebate applied, payback periods can be considerably shortened for eligible households.
Yes. Eligible WA homeowners can apply through the Clean Energy Finance Corporation (CEFC) as part of the Australian Government's Cheaper Home Batteries Program. The program provides interest-free loans to reduce upfront battery costs by around 30%. Ares Energy can help assess your eligibility and find the right battery for your home.
Yes. The STC deeming period shortens each year, reducing the upfront rebate value on new battery and solar installations. Installing in 2025 or early 2026 means you receive the higher current rebate before the May 2026 step-down takes effect. Call us on 1300 717 583 for current pricing.
