Solar Battery Rebate Victoria 2026

Written by Jacob, Last reviewed 2026. This guide is for informational purposes only — see methodology.

Victoria no longer offers its own solar battery rebate. The state's interest-free battery loan program closed to new applications, and Solar Victoria now directs households to the federal Cheaper Home Batteries Program instead^[1]. That program provides a discount on battery installations through Small-scale Technology Certificates (STCs), with the exact amount depending on battery size and installation date.

If you're a Victorian household looking at batteries in 2026, the federal program is your main option. It works through the same Small-scale Technology Certificate (STC) system that covers solar panels, but with separate rules and discount rates.

What Happened to the Victorian Battery Rebate

Solar Victoria used to offer interest-free loans of up to $8,800 for battery installations. That scheme is now closed^[1]. The Victorian Government shifted focus to the Solar Homes panel rebate and hot water rebate instead, while the federal government stepped in with the Cheaper Home Batteries Program from July 2025^[2].

The federal program applies nationally to eligible households, businesses and community organisations, not just Victorian households. The discount is usually shown as an upfront reduction, but some retailers may provide it as a rebate after installation.

How the Federal Battery Discount Works

The Cheaper Home Batteries Program works through STCs, just like solar panels. When you install an eligible battery, it earns a number of STCs based on its usable capacity and the STC factor at the time of installation. The Australian Government purchases an equivalent volume of STCs through the STC Clearing House, which funds the program^[6].

The STC factor drops over time. Here are the factors for batteries installed in 2026^[3]:

• January – April 2026: 8.4 STCs per kWh
• May – December 2026: 6.8 STCs per kWh

From 1 May 2026, the rate also tapers for larger batteries. The first 14 kWh of usable capacity receives the full factor. Capacity between 14 and 28 kWh receives 60% of the factor. Capacity between 28 and 50 kWh receives 15%^[3].

Worked Example: 10 kWh Usable Capacity Battery in Melbourne

Say you're in Melbourne and install a battery with 10 kWh usable capacity in mid-2026. The calculation:

10 kWh usable capacity × 6.8 STC factor = 68 STCs

That's 68 STCs. The installer applies the STC value as an upfront discount. STC prices fluctuate; the actual discount depends on the market rate at installation. Make sure to use the CEC-listed usable capacity for your specific battery — not the nominal or marketed capacity — as STCs are calculated on usable capacity. A 13.5 kWh battery with 13.5 kWh usable capacity gives 13.5 × 6.8 = 91.8, rounded down to 91 STCs^[3]. Your installer or retailer may apply the value as an upfront reduction, or provide it as a rebate after installation. Confirm how it appears on your quote.

Note that for batteries over 14 kWh usable capacity, the tapering starts. A 20 kWh battery with 20 kWh usable capacity would earn (14 × 6.8) + (6 × 6.8 × 0.6) = 95.2 + 24.48 = 119.68, rounded down to 119 STCs^[3].

Eligibility Requirements

The federal program has broad eligibility rules^[2][5]. Batteries must:

• Be between 5 kWh and 100 kWh nominal capacity
• Be installed with a new or existing solar PV system under 100 kW. Grid-only batteries are not eligible. Existing PV systems must meet electrical safety and other program requirements.
• Use a CEC-approved battery system and, where required, a CEC-listed inverter. Existing inverters must meet the program's CEC listing and safety rules.
• Be installed by an SAA-accredited installer
• For grid-connected systems, the battery and inverter must be VPP-capable. Off-grid systems do not need VPP capability but must meet the program's off-grid requirements.
• Be installed on or after 1 July 2025

Support is generally limited to one eligible battery system per premises. Additions or replacements may qualify only where the existing battery system has not already received support and the new or added capacity meets the program rules.

Stacking with the Victorian Panel Rebate

The federal battery discount may stack with the Victorian Solar Homes panel rebate (up to $1,400 + interest-free loan)^[4] if you meet the eligibility rules for each program. You could potentially:

• Claim the $1,400 Victorian solar panel rebate (plus the $1,400 loan if opted in)
• Claim the federal STC discount on your solar panels
• Claim the federal Cheaper Home Batteries STC discount on your battery

All three on the same property. Our Victoria solar rebate guide has the panel details.

How to Access the Discount

You don't apply to the government. Find an accredited battery installer, get a quote, and confirm they'll include the Cheaper Home Batteries STC discount. The installer handles the paperwork, creates the STCs, and passes the value on as either an upfront reduction or a rebate after installation^[2].

If you prefer, you can create and trade the STCs yourself through the REC Registry. Most people let the installer handle it — the discount appears as a line item on the invoice.

The Victorian battery loan scheme is closed. STC prices fluctuate; actual discounts depend on the market rate at installation.
