Every Solar and Battery Rebate Available in Western Australia in 2026: The Complete Guide
WA homeowners have access to more solar and battery financial support in 2026 than at any point in the state’s history. Between state government rebates, federal incentives, export tariffs, and zero-interest loans, a typical Perth household installing a 10 kWh battery alongside solar can reduce the upfront cost by $4,000 to $7,500 depending on their network and timing.
The challenge is that these incentives come from different programs, have different eligibility rules, and some are stepping down every six months. Missing one means leaving real money on the table.
This guide covers every current incentive available to WA homeowners in 2026 — rebate amounts, eligibility criteria, how to stack multiple programs, and how Talk Energy manages the entire process on your behalf.
Last updated: June 2026. STC rates and rebate amounts change regularly. Figures in this guide reflect the current period (May–December 2026).
Quick-Reference: Every WA Solar and Battery Incentive at a Glance
| Incentive | Type | Who It’s For | Max Value (2026) |
|---|---|---|---|
| WA Residential Battery Scheme (Synergy) | State rebate | Perth metro / SWIS customers | $1,300 |
| WA Residential Battery Scheme (Horizon Power) | State rebate | Regional WA customers | $3,800 |
| WA Scheme No-Interest Loan | State loan | Income under $210,000 | $10,000 |
| Federal Cheaper Home Batteries Program (STCs) | Federal rebate | All Australian homeowners | ~$2,500–$3,400 for 10 kWh |
| Solar STCs (panels) | Federal rebate | All Australian homeowners | ~$1,700–$2,700 for 6.6 kW |
| Distributed Energy Buyback Scheme (DEBS) | Ongoing export tariff | Synergy / Horizon customers | 10c/kWh peak export |
| WA Scheme No-Interest Loan | 0% finance | Income under $210,000 | $10,000 |
| Green Personal Loans | Commercial finance | All homeowners | Rates from ~7–9% p.a. |
The most important thing to understand: most of these incentives are stackable. A Synergy customer installing a 10 kWh battery with solar in mid-2026 can combine the WA state rebate with the federal battery rebate and the solar STC discount — reducing total system cost by $5,000 or more before the no-interest loan is even factored in.
WA Residential Battery Scheme
Launched on 1 July 2025, the WA Residential Battery Scheme is the state government’s flagship battery incentive. It pays a fixed rebate per kWh of usable battery capacity, capped at 10 kWh, and is available to both Synergy and Horizon Power customers.
Rebate Amounts
| Network | Rate | Maximum Rebate |
|---|---|---|
| Synergy (Perth metro / SWIS) | $130 per kWh | $1,300 |
| Horizon Power (regional WA) | $380 per kWh | $3,800 |
Batteries larger than 10 kWh still qualify — they simply receive the maximum cap amount. A 13.5 kWh system receives the same $1,300 (Synergy) or $3,800 (Horizon Power) as a 10 kWh system.
Eligibility Requirements
To qualify for the WA Battery Scheme rebate, you must meet all of the following:
- Australian permanent resident, aged 18 or over
- Current Synergy or Horizon Power customer
- Residential property in WA (owner-occupied, investment, or rental with landlord consent)
- Battery installed on or after 1 July 2025 (no retrospective claims)
- Battery has usable capacity of at least 5 kWh
- Battery is on the Clean Energy Council approved list and the relevant Synergy or Horizon Power Supported Solutions List
- Ongoing internet connection at the property for VPP testing
- Must enrol in a Virtual Power Plant (VPP) product for a minimum of two years
The VPP requirement is the one that catches people off guard. Enrolling in a VPP does not mean the grid controls your battery constantly. Under Synergy’s Battery Rewards program, activation events are occasional and Synergy pays $0.70 per kWh exported during those events — meaning VPP participation can generate additional income on top of the rebate.
No-Interest Loan
Eligible households can also access a no-interest loan of up to $10,000 through the scheme, administered by Plenti. Key details:
- Borrow $2,001 to $10,000 at 0% interest
- Repayment terms of 3 to 10 years
- No early repayment penalties
- Covers battery storage plus solar panels or inverter upgrades installed at the same time
- Household gross income must be under $210,000 (verified via 2025 tax return)
- Subject to a credit check
The application is submitted by your approved installer — you cannot apply directly. Talk Energy is an accredited WA Battery Scheme vendor and handles the full application on your behalf. See the WA Battery Scheme eligibility checklist for a step-by-step walkthrough, or visit our WA Battery Scheme overview for more detail.
Federal Incentives: STCs and the Cheaper Home Batteries Program
The federal government’s support for solar and batteries runs through the Small-scale Renewable Energy Scheme (SRES), which creates Small-scale Technology Certificates (STCs) that are converted into an upfront discount on your installation cost. Perth sits in STC Zone 3, giving Perth and regional WA homeowners strong STC values.
Solar Panel STCs
Every eligible solar system generates a set number of STCs based on system size, location, and the year of installation. In 2026, the deeming period is 5 years. For a typical Perth installation:
| System Size | STCs (2026) | Estimated Rebate |
|---|---|---|
| 6.6 kW | ~46 | ~$1,700–$1,750 |
| 10 kW | ~69 | ~$2,600–$2,700 |
| 13.3 kW | ~92 | ~$3,490–$3,500 |
Based on ~$38 per STC. STC market prices fluctuate; your installer locks in the value at time of installation.
The STC discount is applied directly to your invoice — you never need to handle the certificates yourself. The scheme ends on 31 December 2030, with the deeming period stepping down each year.
Federal Battery Rebate (Cheaper Home Batteries Program)
Since 1 July 2025, batteries have also been eligible for STCs through the federal Cheaper Home Batteries Program. From 1 May 2026, the rules changed significantly — the STC factor now steps down twice yearly and a tiered structure applies based on battery capacity.
Current rates (May–December 2026):
| Battery Capacity | STC Factor | Rebate per kWh |
|---|---|---|
| 0–14 kWh | 6.8 (100%) | ~$245/kWh |
| 14–28 kWh | 4.08 (60%) | ~$147/kWh |
| 28–50 kWh | 1.02 (15%) | ~$37/kWh |
| Above 50 kWh | 0 | No rebate |
What this means in practice for common battery sizes:
- 10 kWh battery: ~$2,450 federal rebate
- 13.5 kWh battery: ~$3,300 federal rebate
- 27 kWh battery: ~$5,300 federal rebate (blended tiers)
Key point: The STC factor steps down again in January 2027 (to 5.7), then every six months until the program ends in 2030. Every delay costs money. A 10 kWh battery installed in H2 2026 receives roughly $800 less than the same system installed before May 2026.
For a detailed breakdown of the STC schedule through to 2030, see our guide on solar rebates in WA for 2026.
Distributed Energy Buyback Scheme (DEBS)
The Distributed Energy Buyback Scheme (DEBS) is WA’s ongoing solar export tariff, replacing the old Renewable Energy Buyback Scheme (REBS) for new customers. It is not a one-off rebate — it pays you an ongoing rate for every kilowatt-hour your solar system exports to the grid.
Current DEBS rates (2025–26 financial year):
| Time Period | Synergy Rate | Horizon Power Rate |
|---|---|---|
| Peak (3pm–9pm) | 10c/kWh | 10c/kWh |
| Off-peak (9pm–3pm) | 2c/kWh | 3c/kWh |
A 50 kWh daily export cap applies per premises. For most 6.6 kW systems, this cap is never reached.
Why DEBS Rewards Battery Owners More
The real value of DEBS lies in combining it with a battery. Without storage, most of your solar exports happen during the middle of the day when the off-peak rate (2c/kWh) applies. With a battery, you can store daytime generation and export it during the 3pm–9pm peak window at 10c/kWh — a 5x improvement in export earnings.
The old REBS scheme (7.135c/kWh flat rate) is now closed to new applicants but remains grandfathered for existing customers. If you are on REBS and upgrade your system, you will move to DEBS. For most households, the DEBS peak rate is more valuable when combined with a battery; the flat REBS rate is better for systems without storage.
For a full analysis of how DEBS earnings compare to self-consumption savings, see our guide on the Synergy DEBS feed-in tariff for Perth 2026.
How to Stack Multiple Incentives
This is where WA homeowners can unlock the most value. The WA state rebate, federal battery rebate, solar STC discount, and no-interest loan are all designed to be used together. Here is what a typical combined scenario looks like right now.
Scenario: Synergy Customer, 6.6 kW Solar + 10 kWh Battery (Mid-2026)
| Incentive | Amount |
|---|---|
| Solar STC discount (6.6 kW) | ~$1,750 |
| Federal battery rebate (10 kWh, current STC factor) | ~$2,450 |
| WA Battery Scheme rebate (Synergy, 10 kWh) | $1,300 |
| Total upfront reduction | ~$5,500 |
| WA Scheme no-interest loan (optional) | Up to $10,000 |
A system that costs $16,000 before incentives comes down to approximately $10,500 after rebates — and can be financed with $0 upfront using the no-interest loan.
Scenario: Horizon Power Customer, 6.6 kW Solar + 10 kWh Battery (Mid-2026)
| Incentive | Amount |
|---|---|
| Solar STC discount (6.6 kW) | ~$1,750 |
| Federal battery rebate (10 kWh) | ~$2,450 |
| WA Battery Scheme rebate (Horizon Power, 10 kWh) | $3,800 |
| Total upfront reduction | ~$8,000 |
Regional WA customers on Horizon Power receive significantly more support per battery. The higher $3,800 state rebate reflects the greater cost of energy infrastructure in remote and regional areas.
Rules for Stacking
- The WA state rebate and federal battery rebate can be combined on the same battery — this is explicitly confirmed by the WA Government’s applicant information.
- The combined rebate and no-interest loan cannot exceed the total purchase and installation cost.
- Solar STCs apply to the panel component; battery STCs apply to the battery component. Both can be claimed on the same job.
- DEBS payments are ongoing and do not affect rebate eligibility.
For a detailed walkthrough of the stacking process, see our guide on how to stack federal and WA battery rebates.
Finance Options: Covering the Remaining Cost
After rebates, most Perth households still need to finance $8,000 to $14,000 for a quality solar-and-battery system. These are the main options available in WA in 2026.
WA Scheme No-Interest Loan (Best Option for Most)
For eligible households, the WA Battery Scheme’s 0% interest loan administered by Plenti is the most cost-effective way to finance the remaining balance. With repayment terms of 3 to 10 years and no early repayment fees, this is genuine interest-free credit — not a deferred interest product.
Best for: Households with income under $210,000 installing a CEC-approved battery on the Synergy or Horizon Power Supported Solutions List.
Green Personal Loans
Homeowners who do not qualify for the government no-interest loan — or who want to finance a larger system — can access green personal loans from banks and specialist lenders. These products offer discounted rates compared to standard personal loans because the purpose is a verified clean energy purchase.
| Lender | Product | Rate (indicative, 2026) |
|---|---|---|
| Plenti | Green Loan | From ~7–9% p.a. |
| Brighte | Green Loan | From 9.49% p.a. fixed |
| CommBank, NAB, Bankwest | Green personal loan | From ~7–9% p.a. |
Green loan rates are typically 2–4 percentage points lower than standard personal loan rates in 2026. Always compare the comparison rate (which includes fees) rather than the headline rate.
PACE (Property Assessed Clean Energy)
PACE financing is not yet widely available in Western Australia as a formal government-backed program — unlike some US states. However, the Clean Energy Finance Corporation (CEFC) does offer discounted finance for eligible small businesses and larger commercial solar installations in WA. Residential homeowners should focus on the WA Scheme no-interest loan and green personal loan options above.

Council-Level Rebates in Western Australia
As of mid-2026, there are no active council-level solar or battery rebate programs operating across Perth’s local government areas. Unlike some eastern states where councils have run subsidised bulk-buy schemes or top-up grants, WA’s incentive structure is concentrated at the state and federal level.
A small number of councils have historically offered interest-free loans or sustainability grants for home energy upgrades, but these programs have typically been short-run and are not currently active.
What to watch for: Some WA councils periodically announce community energy initiatives or rebate top-ups, particularly around sustainability budget cycles. Talk Energy monitors these as they are announced. If you are in a regional area, check with your local council directly, as Horizon Power service areas occasionally have community-specific programs.
For now, the meaningful financial support for WA homeowners comes from the state and federal programs covered above.
How Talk Energy Manages Your Rebates
Navigating multiple rebate programs — each with their own approved product lists, application portals, VPP requirements, and income verification — is genuinely complex. Most homeowners who try to manage it independently miss steps, submit incomplete applications, or choose a battery that qualifies for one scheme but not another.
Talk Energy is an accredited WA Battery Scheme vendor. That means we handle the rebate application process end-to-end, including:
- Confirming your eligibility for the WA state rebate and federal battery program before you commit
- Selecting batteries from the Synergy or Horizon Power Supported Solutions List that maximise your combined rebate
- Submitting the WA Battery Scheme application on your behalf through the Plenti portal
- Coordinating your VPP enrolment so the scheme conditions are met from day one
- Applying the STC discount directly to your invoice — you never need to handle certificates
- Advising on the no-interest loan if your income qualifies and it suits your situation
The result: you receive every dollar you are entitled to, with no paperwork and no risk of missing a program due to a technicality.
Talk Energy also offers a 20-year workmanship warranty with a 48-hour fix guarantee — meaning the system we install and the rebates we secure are backed by long-term support, not a fly-by-night quote.

Frequently Asked Questions
Can I get the WA Battery Scheme rebate if I already have solar?
Yes. The WA Battery Scheme is available for new, additional, or replacement battery systems. You do not need to install solar at the same time. However, the no-interest loan can only be used for solar panels if they are installed simultaneously with the battery.
Can renters access the WA Battery Scheme?
Yes, provided you have written consent from your landlord to install the battery. The property must be your primary residence or a long-term rental. Government-owned housing is excluded.
Do batteries installed before 1 July 2025 qualify?
No. The WA Residential Battery Scheme is not retrospective. Only batteries installed on or after 1 July 2025 are eligible.
What is the VPP requirement and does it affect my battery use?
To receive the WA state rebate, you must enrol in a Virtual Power Plant (VPP) for a minimum of two years. Under Synergy’s Battery Rewards program, your battery may be called upon to export energy to the grid during activation events — but these are infrequent and Synergy pays $0.70 per kWh during those events. Your battery remains available for your own use the vast majority of the time.
Can I stack the WA state rebate with the federal battery rebate?
Yes. The WA Government explicitly confirms that the state scheme is designed to complement the federal Cheaper Home Batteries Program. Both rebates apply to the same battery installation. A Synergy customer with a 10 kWh battery can receive $1,300 (state) plus approximately $2,450 (federal) in combined upfront rebates.
How long does the WA Battery Scheme rebate take to process?
Your approved installer submits the application on your behalf. Conditional approval is typically received within a few weeks, after which you have up to six months to complete the installation. If the six-month window lapses, you must reapply.
Are there income limits for the WA Battery Scheme rebate?
There is no income limit for the rebate itself. The income limit (under $210,000 household gross income) only applies to the no-interest loan component.
What happens to my DEBS payments if I join a VPP?
DEBS payments continue normally. VPP activation events are separate from your standard DEBS export earnings. During a VPP event, Synergy pays the Battery Rewards rate ($0.70/kWh) rather than the standard DEBS rate — which is actually higher than the peak DEBS rate of 10c/kWh.
