Small-scale technology certificates, or STCs, are a tradable commodity attached to eligible installations of renewable energy systems (including solar panels, solar water heaters and heat pumps).

Under the Federal Government’s Small-scale Renewable Energy Scheme (SRES), when you install an eligible system, you may claim a set number of these STCs.

The number of STCs is based on the amount of electricity in megawatt hours (MWh):

• generated by your small-scale solar panel, wind or hydro system over the course of its lifetime of up to 15 years; or
• displaced by your solar water heater or heat pump over the course of its lifetime of up to 10 years.

The value of a STC fluctuates based on supply and demand. These are drive by the annual target, the creation and the liable entities liability. Since STCs are tradable, their worth can change daily. Fear not! Once Greenback gets your forms spot on, we'll set the price for you. Stay in the know with our daily rates available on our home page

If you are claiming the STC payment as the owner of the property, you do not need to register with Greenbank, simply ensure the STC Assignment Form is completed in full and provide your bank account information in the payment details section for payment via direct deposit.

Installers, suppliers and builders wishing to trade regularly are required to complete an account application form in order to establish a trading account. Please phone our office and we can provide the appropriate forms.

Victorian Energy Efficiency Certificates (VEECs) are electronic certificates created in accordance with the Victorian Energy Efficiency Target Act 2007 (VEET Act). They encourage the uptake of energy efficient technology and play an important role in achieving the Victorian government’s target of reducing greenhouse gas emissions from households.

VEECs can only be created from prescribed activities undertaken on or after 1 January 2009 and before 1 January 2030. An old system, capable of working, must be decommissioned and a new, registered product installed. For the complete list of activities and registered products visit:

The Greenbank VEEC Assignment form must be completed. Forms can be downloaded at http://www.green-bank.com.au/veec/forms. All information requested on the form must be provided as it is required by the ESC for the creation of VEECs. Supporting documentation must be provided with the form to complete your claim. A copy of the plumbing certificate of compliance and a copy of the invoice from the installer/supplier must be provided with the VEEC form. Claims cannot be processed without copies of both supporting documents.

If the system is owned by a business, GST is payable on the VEEC transaction, thus a Tax Invoice needs to be provided to Greenbank for payment to be made.

PRCs, or Peak Reduction Certificate (PRC) under the NSW Energy Savings Scheme is an incentive for installing a behind the meter solar battery at Residential and Small Business sites in New South Wales.

This is a scheme only available to Companies with accredited installers, as they need to be inducted into the scheme prior to completing installs.

It represents 0.1 kilowatts of peak demand reduction capacity averaged over one hour during the peak summer period, which occurs between: 1 November and 31 March.

Eligible scenarios are called activities under the PDRS Scheme.

SASC Method (Store and Shift Capacity sub-method) : BESS1

Install a new behind the meter battery energy storage system, which will commence on 1 November 2024.

Use our NSW Battery Calculator https://www.green-bank.com.au/...

First the battery must appear on the Clean Energy Council (CEC) approved battery list

Clean Energy Council Battery List

and second the Manufacturer Battery warranty must state the following to meet the PDRS scheme’s following criteria to be eligible for PRCs.

• Battery is internet connectable & controllable.
• Usable Battery Capacity greater than 2kWh and less than 28kWh
• Guarantee of at least 70% of usable capacity being retained 10 years from the installation date.
• Define the normal use conditions during the operation of the battery as not being less than:
  • A minimum ambient temperature range of -10 C to 50 C
  • Minimum warranted throughput of Usable Battery Capacity Prior to 1st April 2026 - 2.8 Mwh per Kwh, After 1st April 2026- 3.65 Mwh per Kwh

The usable Battery Capacity must greater than 2kWh & less than 28kWh – this information will be on the battery factsheet/warranty.

Batteries with capacity outside this range will not be eligible – for example if installing a battery with 30kWh of usable capacity you cannot so a partial claim of 28kWh

Where a Battery Energy Storage System is comprised of multiple batteries, each individual battery unit must be listed on the CEC’s list of approved batteries, and meet the additional scheme requirements, and the combined Usable Battery Capacity of the battery system must be greater than 2kWh and less than 28kWh.

• They are installed on the same day behind the same NMI, and collectively constitute a system. A system can be comprised of batteries with or without built-in inverters.
• Each individual battery must be listed on the Clean Energy Council’s approved batteries list.
• The total Usable Battery Capacity of all the batteries (as they are listed on the Clean Energy Council’s approved batteries list) must be greater than 2 kWh and less than 28 kWh.
• Each battery must meet the warranty requirements in the Activity Definitions.

For BESS1, a site with an existing battery is still ineligible – the installation of additional capacity at a site with an existing battery is not eligible for certificates.

The installation must be conducted by an installer with an Unrestricted electrical license and Grid-Connected Battery Storage ‘Design and Install’ or ‘Install only’ accreditation by Solar Accreditation Australia (SAA).

They must also complete the Greenbank Installer induction before receiving logins to our portal.

No, PRCs cannot be claimed for batteries that were installed but not commissioned before November 1.

You need to demonstrate that there was no existing battery at the start of the installation after November 1.

IPART don't have any specific inverter requirements for the existing solar setup or a hybrid inverter; however, they must comply with all other relevant standards and applicable legislation.

• The installer must ensure that the battery site inside a garage or an acceptable non-habitable room has a functioning smoke alarm or request one to be installed, prior to installation of the battery equipment.

• Where the property's existing smoke alarms are interconnected, either wired or wireless, the new smoke alarm shall be interconnected to the existing smoke alarms.

• Where a battery system is installed externally or in an open carport area, installation of a smoke alarm is not a requirement of the Scheme.

PDRS requirement is :

1. Evidence of a smoke alarm installed nearly, and of its compliance with AS3786
2. Geo-tagged photo clearly showing location of the smoke alarm in relation to the installed battery
3. Battery declaration – installer signs off that is complies with AS3786 and was tested by installer and in working order on the implementation date

With the introduction of new battery rebate programs in Queensland and the ACT this year, and a proposed rebate in NSW expected in November, the safe installation of batteries has become an increasingly important topic. A common concern among installers is determining suitable battery installation locations, particularly regarding what constitutes a habitable room and a restricted location.

The main standards that cover battery installation locations are:

• AS/NZS 5139:2019
• AS/NZS 3000:2018
• AS/NZS 4777 (for inverters)

Although these standards have specific requirements for where batteries can and cannot be placed, it’s important to use common sense when applying these rules. The main goal is to install batteries in safe locations so that in the case of a fire or explosion, it is unlikely that people will be near the battery and, if they are, they can exit the room safely.

Restricted Locations

AS/NZS 5139:2019 dictates batteries CANNOT be installed in restricted locations. Restricted locations include:

1. Any restrictions as defined for switchboards (AS/NZS 3000)
2. Within 600mm of any exit or entry
3. Within 600mm of any vertical side of a window, or any building ventilation, opening into a habitable room
4. Within 600mm of any appliance
5. Within 900mm below 2, 3, and 4
6. In ceiling spaces
7. In wall cavities
8. On roofs (except where specifically deemed suitable)
9. Under stairways
10. Under access walkways
11. In an evacuation route or escape route.
12. Within a habitable room

An exit, as mentioned above, includes garage doors. However, according to the ERAC clarification, for all states but NSW, if a person can enter/exit the garage 900mm from the battery, it can be less than 600mm from the garage door. See the ERAC clarification here for more information: https://www.erac.gov.au/wp-con...

Habitable Rooms

A habitable room is defined as a room associated with a domestic or residential electrical installation used for normal living activities and includes:

1. Bedroom
2. Living room
3. Lounge room
4. Music room
5. Television room
6. Kitchen
7. Dining room
8. Sewing room
9. Study
10. Playroom
11. Family room
12. Home theatre
13. Sunroom

Note that a garage that is used as lounge room or workspace may also be considered a habitable room. We recommend avoiding installing batteries where the homeowner might spend a considerable amount of time.

Additionally, any manufacturer clearance zones need to be maintained for batteries, inverters, and switchboards. These can vary, and you must check the manufacturer’s documentations, but a general rule of thumb is often 200-300mm on all sides of the equipment.

So, considering all of these restrictions, where can a battery be installed? The best options are outside of habitable rooms if there is a suitably non-combustible material (see below) between the battery and the habitable room. Other options include, a garage, laundry, or storage room if the appropriate clearances between windows, doors, and appliances are maintained. Ancillary buildings such as a shed could also be used, but care needs to be made when considering distance from the switchboard, cable sizing/voltage drop and the necessary battery clearance values.

Non-Combustible Barriers

Materials deemed suitably non-combustible based on AS 1530.1:

1. Brick or masonry block
2. Concrete
3. Compressed cement sheeting
4. Ceramic or terracotta tiles

When installing the battery on a wall shared with a habitable room that is made of combustible material (e.g. wood), a non-combustible barrier must be placed between the battery and the wall. This barrier must extend 600mm to each side of the battery and 900mm above the battery even if there is a corner or a roof (so that it wraps around the corner or ceiling). We also recommend adding a non-combustible barrier if the wall is shared with a staircase or main walkway, fore example, near the front door of the house.

For examples of non-combustible barrier installations and other important information, please see the GHD Battery Booster Installation Guide.

Outdoor Installation

Please note, if you are installing a battery outside, care needs to be taken to not install it in direct sunlight. This can either be on the southern wall of the building, beneath eaves, or a fabricated shroud assuming the necessary clearances (900mm from the top) are maintained. Excessive sunlight can bring the battery temperature out of its acceptable range, voiding the warranty and creating a potentially dangerous situation due to thermal runaway of the battery.

The Battery STC Scheme might be stackable with the NSW Peak Reduction Certificates (PRCs). This is contingent on rule changes by the NSW Government.
Currently not eligible.

• Battery and inverter must be listed on the CEC Approved Product List.
• Nominal battery capacity must be between 5–50 kWh.
• If the Nominal battery capacity is 5-100 Kwh you can only claim STCs on the first 50 Kwh.
• Both residential and commercial installations are eligible.

Unlike solar PV, only one battery is eligible at each address, once.

• Installer must be SAA-accredited.
• Installation must comply with AS/NZS 5139 and AS/NZS 3000 standards.

What Has Changed
• From 1 July 2025, accreditees who previously held SPS Design & Install Accreditation but did not hold an unrestricted electrical license have been transitioned to: SPS Design & Install ELV (Extra Low Voltage).

Where Is This Reflected
• These changes appear in the Accredited Persons List, with affected individuals listed under SPS Design & Install (ELV).

What Systems Can ELV-Accredited Persons Sign Off On
• Only systems operating at Extra Low Voltage (ELV) on both AC and DC sides.
• They cannot sign off on systems operating at Low Voltage (LV).

Voltage Definitions (AS/NZS 3000)
• ELV:
    o 0–50V AC
    o 0–120V ripple-free DC
• LV:
    o 50–1000V AC
    o 120–1500V ripple-free DC

Who Can Sign Off on LV Systems
• Only installers with unrestricted electrical licences and SPS Design & Install (Full) accreditation.
• These individuals can install both ELV and LV battery and solar systems – off-grid and on-grid.

Licence Verification
• To confirm the type of licence an installer holds, use the SAA Licence Status Check tool.
• Required:
    o SAA Accreditation Number
    o First and Last Name
• SAA Licence Status Check - SAA Licence Status Check

• Use the Greenbank STC Battery Calculator on our website - Greenbank STC Battery Calculator 
• STCs are calculated based on usable battery capacity (kWh).
• Battery eligibility is based on a nominal capacity of 5–50 kWh.
• The discount rate in 2025 would be represented as 9.3 STCs per kWh of usable capacity.
• The number of STCs will decline for battery systems until the scheme ends in 2030.

• The nominal capacity is the maximum amount of energy a battery can store at full charge.
• The usable capacity of the battery is the amount of energy that can be discharged from a battery and represents the power that a home or business can draw from the battery.
• For example, a battery with 10 kWh nominal capacity with a depth of discharge of 90% has a usable capacity of 9 kWh.
• Information on the nominal and usable capacity of a battery system is available on the CEC’s list of approved battery products.

• The program will provide support for a battery system that is installed with an existing solar PV system, or where a battery system and new or replacement solar PV system are installed together.
• Solar PV systems should have less than 100 kW in capacity as eligible under the SRES.
• There are no minimum capacity Solar PV system size restrictions.

• Battery systems installed without solar PV (which solely store energy from the grid) will not be eligible.
• This is to support storing excess solar energy during the day to provide for peak evening electricity needs.

Battery systems can be added to existing solar PV systems if the addition does not impact the safe function of the system.

At the time of battery installation, the inverter model must:
• Not be ineligible under the Renewable Energy (Electricity) Regulations 2001
• Be listed on the CEC approved product list

If the inverter model has been removed from the CEC approved products list, it may still be eligible under the program if its removal was not due to an identified safety risk – you will need to provide evidence of the latter.

Adding capacity to, or replacing, an existing battery can receive support under the program if:

• The solar battery has not previously claimed STCs
• The additional nominal capacity is at least 5 kWh, with the total nominal capacity of the system not exceeding 100 kWh, including pre-existing batteries.
• The existing battery has not already received support under the program, and
• The new battery system or the additional capacity meet the nominal capacity requirements

Scenarios (existing battery with 4 kWh):

• Adding a battery of 4 kWh would NOT be eligible (under the minimum 5 kWh threshold)
• Adding a battery of 6 kWh would be eligible (exceeds the minimum 5 kWh threshold)
• Adding a battery of 95 kWh would be eligible (under the 100 kWh maximum)
• Adding a battery of 97 kWh would NOT be eligible (exceeds the 100 kWh maximum)

A Virtual Power Plant (VPP) is a system of coordinated behind-the-meter solar PV and battery systems that act as a single power source and enable energy to be shared.

To be eligible under the program, an on-grid battery system (including the inverter) needs to have the technical capability to participate in a VPP. This would provide the consumer with the option to participate in a VPP at the time of installation or in the future.

A battery is VPP capable if the inverter:
• Can connect to the electricity grid and external entities (directly or indirectly)
• Can communicate and respond through remote signals

Participation in a VPP is not a requirement of the program. However, if consumers would like to participate in a VPP, this will require an ongoing internet connection.

Off-grid battery systems do not need to be VPP capable. However, if a VPP capable battery system is installed at a premises that is off-grid, it can still receive support under the program.

New battery modules being added to an existing stackable battery system are eligible for small-scale technology certificates (STCs). We’ve outlined the requirements and provided instructions on how to claim STCs for the new battery modules in REC Registry.

Stackable battery systems are modules of battery cells that can be ‘stacked’ together without external wiring. 

These modules are normally topped with an inverter, control unit or other component that helps the stack work as a single unit. 

Adding battery modules to a stackable battery system is a normal practice and can be safe as long as the work is undertaken safely and manufacturer’s requirements and Australian Standards are met.

STCs can be claimed for new battery modules added to an existing stackable battery system where:

• the final configuration of the stackable battery system is on the CEC’s approved product list at the date of certification. If the battery management module, or another component no longer matches the current approved product, then the system is ineligible.
• the SAA accredited installer completes the installation and re-certifies the entire system, including the connection to the electrical installation, as safe, compliant and meeting all requirements. The installer is expected to identify and upgrade if any parts of the existing system required. There may be other jurisdictional requirements installers need to comply with such as inspections or notifications to Distribution Network Service Providers.
• the additional modules and existing system are compatible in all ways and are within manufacturer specifications to add modules in that way.

Any non-compliance of the final system, identified through a CER inspection or other means, will be considered the responsibility of the accredited installer or designer as appropriate. This applies to non-compliance for both added and existing components. 

Installers must hold a current Solar Australia Accreditation for Batteries

For Grid Connected Battery installations:

The installer must be accredited holding accreditation - GCBS (FULL)

For Off Grid Battery Installations

There are x2 categories for Off Grid ONLY installations

1. SPS(FULL)-  Off-Grid Connect Battery Systems
2. SPS(ELV) – Off-Grid Battery Systems – ELV system ONLY

Accreditees who hold SPS ELV accreditation with SAA are restricted to signing off on the installation of systems which operate at Extra Low Voltage (ELV) on both the AC and DC side. They can no longer sign off on installation of systems that operate at Low Voltage (LV).

The voltage limits as set out in AS/NZS 3000 are as follows:

1. ELV – 0-50V AC and 0-120V ripple free DC
2. LV – 50-1000V AC and 120-1500V ripple free DC

Check the battery data sheet to identify what category the battery falls into.

Does my installer have the right accreditation?

To check is your installer is accredited go to the on SAA website - Installer Accreditation Status Check
