Victoria’s old interest-free battery loan is closed — but in 2026, Victorian households can still get a major upfront discount on eligible solar batteries through the Australian Government’s Cheaper Home Batteries Program, delivered via Small-scale Technology Certificates (STCs). The key is understanding the eligibility rules, the value step-downs, and the big change coming on 1 May 2026 that reduces support for larger batteries.

Current Status of the Solar Battery Rebate in Victoria
The Victorian Solar Homes Battery Loan – Now Closed
The Victorian Government previously offered interest-free battery loans under the Solar Victoria program, part of the broader Solar Homes Program.
The scheme provided:
- Up to $8,800 interest-free loan
- Support for thousands of households
- Designed to run until 30 June 2025
However, applications have now closed after exceeding program targets. According to Solar Victoria updates (see: https://www.solar.vic.gov.au), the battery loan program is no longer accepting new applicants.
While this has disappointed some households, the strong uptake demonstrates the growing demand for home energy storage across Victoria.
But the story doesn’t end there.
Cheaper Home Batteries Program (2025–2030)
The most important development for 2026 is the federal Cheaper Home Batteries Program, delivered through the Small-scale Renewable Energy Scheme (SRES).
Official federal information can be found at:
- Clean Energy Regulator: https://www.cleanenergyregulator.gov.au
- Department of Climate Change, Energy, the Environment and Water (DCCEEW): https://www.dcceew.gov.au
Key Program Details
- Starts: 1 July 2025
- Budget: $2.3 billion
- Discount: ~30% off eligible battery systems
- Capacity eligible: 5 kWh – 50 kWh (rebate capped at 50 kWh)
- No means testing
- Available to households, small businesses, and community facilities
- Can be combined with eligible state incentives
This program is expected to significantly accelerate battery adoption nationwide, including in Victoria.
Eligibility Criteria Checklist (VIC Households)
Your installer normally handles eligibility checks, but you should understand the rules so you can verify quotes and avoid unpleasant surprises.
1. Battery + Installation Eligibility (Federal Program)
To qualify for STCs (and therefore the upfront discount), the system generally must meet requirements including:
- Installed with new or existing rooftop solar PV (PV capacity up to 100 kW or less under the scheme guidance)
- Battery is new (used batteries moved to a new premises are not eligible)
- Nominal capacity: total battery system nominal capacity must be at least 5 kWh and not exceed 100 kWh
- STC eligibility cap: only the first 50 kWh usable counts for STCs
- One battery system per premises is eligible for STCs
- VPP-capable inverter/battery system (on-grid), but VPP participation is not required
- Products must be listed on the CEC approved lists (battery + inverter at time of installation/certification)
- Installer/designers must be SAA-accredited (and appropriately accredited for batteries)
Tip: Ask for the installer’s SAA accreditation number and verify it using SAA’s official accreditation status check.
2. Solar Homes PV Rebate Eligibility (If You’re Also Installing Solar)
If you’re stacking with Victoria’s PV rebate, Solar Victoria’s eligibility typically includes:
- owner-occupier (existing home) or owner of a home under construction
- combined household taxable income of owners under $210,000
- property value under $3 million
- address hasn’t previously received a Solar Homes PV or battery rebate under the program
Also note: the Solar Victoria PV rebate is a discount up to 50% of purchase cost, capped at $1,400, calculated after discounts like STCs.
How Much Money Can Be Saved?
These are illustrative calculations using the regulated $40/STC reference price.
1. If Installed Jan–Apr 2026 (STC Factor 8.4)
No tapering is listed until 1 May 2026.
| Usable Capacity | Est. STCs (kWh × 8.4) | Est. Discount @ $40 | Est. Discount @ $36 |
|---|---|---|---|
| 5 kWh | 42 | $1,680 | $1,512 |
| 10 kWh | 84 | $3,360 | $3,024 |
| 13.5 kWh | 113.4 | ~$4,536 | ~$4,082 |
| 20 kWh | 168 | $6,720 | $6,048 |
2. If Installed May–Dec 2026
From 1 May 2026, the CER/Department describe tapering:
- 0–14 kWh: 100% factor
- 14–28 kWh: 60% factor
- 28–50 kWh: 15% factor
| Usable Capacity | Est. STCs (With Taper) | Est. Discount @ $40 | Est. Discount @ $36 |
|---|---|---|---|
| 5 kWh | 34.0 | $1,360 | $1,224 |
| 10 kWh | 68.0 | $2,720 | $2,448 |
| 13.5 kWh | 91.8 | ~$3,672 | ~$3,305 |
| 20 kWh | ~119.7 | ~$4,788 | ~$4,308 |
| 27 kWh | ~148.3 | ~$5,932 | ~$5,339 |
| 40 kWh | ~161.6 | ~$6,464 | ~$5,818 |
40 kWh looks “low” versus a straight line because tapering reduces support for larger systems. Energy.gov.au provides a real-world reference point: under the program, a household could save roughly $4,000 on an ~11.5 kWh battery previously costing around $13,000, and annual bill savings across households are often cited in the $700–$1,600/year range (with the battery contributing a significant part of that).
In Victoria specifically, Solar Victoria has stated that households with moderate usage pairing solar PV and a mid-sized battery can expect around $1,400/year savings and a return on investment over about 10 years (context and outcomes vary by tariff and usage).
Payback depends heavily on:
- when you use electricity (evening-heavy homes benefit more),
- your feed-in tariff vs import tariff,
- whether you join a VPP and how it’s structured,
- and whether your battery is sized correctly for your solar PV and inverter.
Step-by-Step: How to Claim the Battery Discount (VIC)
If you’re installing a home battery in Victoria, here’s how the federal battery discount process typically works.
Step 1: Confirm You Meet the Key Eligibility Rules
Before requesting quotes, check that your system meets the core requirements:
- 5–100 kWh nominal capacity
- Installed with solar PV
- VPP capable (for on-grid systems)
- One battery per premises rule applies
Confirming eligibility early helps you avoid delays or rejected claims.
Step 2: Choose the Right Installer (Critical for Eligibility)
Your battery system must be installed (or directly supervised onsite) by an SAA-accredited battery installer and comply with all Victorian electrical safety regulations. If the installer is not properly accredited, the discount may not be valid.
Step 3: Verify the Battery & Inverter Are CEC Approved
Check that your exact battery model and inverter configuration are listed on the Clean Energy Council (CEC) approved product list at the time of installation. Approval must match the specific model and setup—not just the brand name.
Step 4: Request a Formal Quote (With the Discount Clearly Shown)
In most cases, households do not apply directly to the government. Instead, accredited installers or retailers apply the discount through the STC mechanism. Ask your installer to clearly specify:
- The estimated STC count
- The STC price used in calculations
- Whether the discount is applied upfront or post-installation
Transparency here ensures you understand the real net system cost.
Step 5: Installation & Compliance Certificate Date
Under program guidance, your battery is considered officially installed based on the date the Certificate of Electrical Compliance (CoC) is issued. This date determines eligibility timing for STCs—so keep documentation safe.
Step 6: STCs Are Claimed “Behind the Scenes”
Your installer or their registered agent will:
- Create the Small-scale Technology Certificates (STCs)
- Trade/sell the STCs
- Pass the value back to you through the upfront discount
From your perspective, the benefit appears as a reduced system price on your quote or invoice.
Can You Stack VIC Incentives With the Federal Battery Discount?
In many cases, yes — but stacking depends on each program’s rules and timing.
- The federal program is designed to complement state and territory incentives, and it explicitly notes you may be eligible for multiple schemes.
- For Victoria specifically, you may pair the federal battery discount with Solar Homes incentives such as the PV rebate (up to $1,400) where eligible.
If you’re doing a solar + battery bundle, ask your installer to show:
- the battery STC discount,
- any PV STCs,
- and any Solar Victoria rebates/loans separately, so you can compare quotes apples-to-apples.
For Installers, Distributors & EPCs
If you’re sourcing batteries through a manufacturer (for example, modular LFP (LiFePO4) systems for residential or light commercial projects), STC eligibility should be a non-negotiable checkpoint in your procurement workflow. Under the Cheaper Home Batteries framework, the discount is tied to compliance and approved pathways — meaning the exact battery model you sell and install must align with Australian requirements, including:
- Product approval pathways (e.g., being eligible under the Clean Energy Council (CEC) approved product listing where required)
- Correct installation standards and commissioning (e.g., compliance with Australian standards and electrical rules)
- Accredited installation (e.g., Solar Accreditation Australia (SAA) accredited practitioners where applicable)
Avepower works with B2B partners (installers, wholesalers, and project developers) who need batteries that are easier to document, specify, and deploy at scale. For procurement and compliance reviews, Avepower can support your project with a documentation pack typically required during tendering and technical evaluation, such as:
- Battery architecture details (modular design, stackable options, scalable capacity planning)
- BMS protection overview (safety logic, monitoring, fault handling)
- Test and shipping documentation commonly requested by buyers (e.g., UN38.3, MSDS, packaging specs)
- International compliance references often used in technical submissions (e.g., CE, RoHS, ISO quality systems), plus model-specific reports where available
- Integration information for installers (interfaces, communication options such as CAN/RS485/RS232 depending on configuration)
If you’re planning a residential or small C&I rollout and want a recommended configuration (battery size, modular expansion plan, inverter integration notes, and documentation pack), contact Avepower: info@avepower.com

FAQ
Victoria’s interest-free battery loan is closed to new applications. In 2026, most battery savings come from the federal Cheaper Home Batteries Program discount via STCs.
No. You can add a battery to an existing solar system.
Most eligible systems fall within a 5 kWh to 100 kWh nominal capacity range. However, the STC discount generally applies only up to 50 kWh of usable capacity, and larger systems may receive reduced support depending on program rules.
Ask for their Solar Accreditation Australia accreditation number and verify it using SAA’s official status checker.
The federal battery discount may be used alongside eligible Victorian incentives such as the Solar Homes PV rebate (if you qualify). Stacking rules can vary, so it’s important to ask your installer to itemise each discount clearly.
To access STC-based discounts, installations generally must be completed by an appropriately Solar Accreditation Australia (SAA)-accredited installer (and comply with all electrical safety requirements). Ask for the installer’s accreditation number and confirm it online.
