Federal Government Solar Rebate

Small-scale Renewable Energy Scheme

The Federal Government solar rebate, officially known as the Small-scale Renewable Energy Scheme (SRES), entitles individuals and small businesses in Australia to large reductions when installing eligible small-scale renewable energy systems (under 100kW) such as solar PV systems and solar water heater systems.

The rebate amount is determined by the number of small-scale technology certificates (STCs) a solar system is entitled to. The larger the solar system the more STC’s it will receive. Every year on January 1st the amount of STC’s a solar system is granted decreases meaning the rebate decreases. An average residential-sized system can currently receive up to $3,458.

    What are STC’s?

    Small-Scale Technology Certificates (STCS) are certificates that system owners or installers can trade in exchange for an upfront discount to the cost of a solar system. STC’s have a dollar value that can fluctuate depending on solar system demand, changes in Government and other industry factors. The larger the solar PV system the more STC’s it is entitled to, the more STC’s, the greater the rebate. 

    For the purpose of the Solar Rebate, Australia is segmented into zones ranging from 1-4. What zone an area is has been determined by how much clean, renewable energy a solar system can generate in that location. Locations in Zone 1 receiving the highest amount of STC’s and those in Zone 4 receiving the least.

  • Important things to know about the Small-scale Renewable Energy Scheme:
    • The value of STC will rise and fall depending on demand
    • The number of STCs you’re entitled to will decrease each year up until 2030 when the scheme is scheduled to finish
    • The solar installer will claim the rebate on your behalf and quote your system and installation with the discounted rate (You must select a CEC accredited installer to receive the rebate)
    • Most providers and installers advertise their systems inclusive of the SRES rebate
    • A Feed-in Tariff (FIT) is different from the SRES and is a reimbursement that you receive for the excess energy a solar system generates and is exported to the grid.
    • Systems over 100kW (commercial size) are not eligible for the SRES however they may be eligible for the Large-scale Renewable Energy Target (LRET)
  • Value of the Federal Government Small-scale Renewable Energy Scheme

    Federal Government Solar Power Rebate Value in 2021

    A simple way of estimating the rebate amount is to multiply the STC $ value by the amount of STC’s a system is entitled to. As the STC value can fluctuate anywhere between $34-$40 the below estimations are based on the STC value at $38.

    (Number of STC’s x STC Price = Value of Subsidy)

State Based Incentives

Solar Homes Program

As well as the Federal Government SRES subsidy Victoria residents have access to ONE of the below rebates;

  • Solar Panel Rebate (Fortnightly releases)
  • Solar Hot Water Rebate
  • Renters Solar Scheme 
  • Home Battery Subsidies (subject to postcode)

The Solar Homes program will run over 10 years and will support the installation of more than 650,000 solar PV systems for owner occupiers, 50,000 solar PV systems for landlords and tenants, 10,000 battery storage systems, and 60,000 solar hot water systems.

UPDATE: The Solar Panel Rebate has now been updated so that there will be two releases of rebates each month, two weeks apart.

For the remaining rebates (Hot Water, Renters Solar Scheme & Battery) there is a set number of rebates which are released each month.

Solar Victoria has a one-stop online portal available for rebate applications to be completed on by the Solar Provider and Customer. The Solar Provider must be registered with Solar Victoria to take part in the Solar Homes program. Some rebates will be reserved for manual applications for those who choose not to engage online. 

The Solar Provider will quote the customer with the deducted rebate amount in which the Solar Provider will be able to claim via the portal after the installation is complete. 

    • Interest Free Loans to cover the remaining upfront costs for those installing a solar PV system will also be available. This can be used in conjunction with the Solar Panel Rebate and Renters Solar Scheme.
    • An applicant can apply only once as an owner-occupier (one of solar PV, batteries or hot water only) and once as a landlord (solar PV only).

Solar Panel Rebate 

The Solar Panel Rebate entitles Victoria households to receive up to $1,400 towards purchase and installation of a solar PV system.

This is on top of the Federal Government Rebate that was already in place. Being able to claim both subsidies will mean that you can save approximately two-thirds of the overall costs of a solar system.


    • The household has a combined income of less than $180,000 per annum before tax
    • The household does not already have a solar panel system installed
    • You are a home owner-occupier of a home that is valued at under $3,000,000

*If you already have a solar PV system and it was installed prior to the 1st of November, 2009 you are also eligible for the Solar Panel Rebate.

Solar Hot Water Rebate

Solar hot water rebates are available up to $1,000 for solar hot water systems. A good option for households who cannot install a solar PV system.

The solar hot water rebate applies to installations that replace an existing hot water system that was at least three years old (from the date of purchase) and it’s not available to new build homes (new Class 1 buildings). Households can only access one rebate type under the solar homes package (i.e. a household that accesses a Solar PV rebate cannot claim a solar hot water rebate and vice versa).


  • The household has a combined income of less than $180,000 per annum before tax
  • The household does not already have a solar panel system installed
  • You are a home owner-occupier of a home that is valued at under $3,000,000
  • Are you replacing an existing hot water system OR an existing solar hot water system that is at least three years old?
  • Confirm that you haven’t applied for or received a rebate for solar PV under the Solar Homes Package

Renters Solar Scheme

Stream A – (Rebate only) will give landlords a rebate up to $1,400 towards a solar system for their rental property and then the landlord will be required to pay the rest.

The rebate amount will be paid directly to the solar provider and will be deducted from the total cost of the system, with the landlord paying the outstanding balance directly to the provider once installed.

Stream B – Stream B will offer both a rebate and an interest-free loan to landlords. This stream will be available to eligible landlords and tenants subject to the signing of a Solar Homes Landlord Rebate and Loan Agreement between Landlord and Tenant(s). Under this stream the tenant(s) will contribute to the cost of the system.

The rebate will be subject to new rental lease agreement between the tenants and landlord.


  • Tenant/s in the rental property have a combined household taxable income of less than $180,000 per year
  • Rental property is valued at under $3 million
  • Rental property does not already have solar panels (PV) installed
  • Rental property address has had no previous participation in the Solar Homes Program

Home Battery Subsidies

Rebates for up to half the value capped at $4,174 of the installation of a battery storage unit for 10,000 households that already have solar panels installed.

The new Battery Rebate will start off as a Battery Pilot Rebate Scheme and only be eligible to households within certain postcodes. While the list of eligible postcodes may change throughout the program the current list has been selected due to the following criteria;

  • Postcodes have a high proportion of households with existing solar PV systems; and
  • In an area where the electricity grid can cope with the additional power the battery will provide.

Find Eligible Postcodes Here


  • Owners have a combined household taxable income of less than $180,000 per annum (based on last year’s Australian Tax Office Notice of Assessment (NOA))
  • Existing property, valued at under $3 million
  • Already has solar panels (PV) installed
  • Sits within a targeted growth area, as identified by Solar Victoria

Rebate Amount ($)

Rebate Amounts ($) 1st July 2021 - 30th June 2022
Solar Panel (PV) $1,400
Solar Battery $4,174 to be reduced to $3,500
Solar Hot Water $1,000

Solar Interest Free Loans

Interest-free loans up to $1,400 will be available for solar PV systems under the program. This will allow Victorians to access the benefits of renewable energy at no up-front cost. 

Renters will also be able to access an interest-free loan for a solar PV system under the solar rental property scheme. Households will be required to pay back the amount of the loan over four years, which will assist Victorians with budgeting for their cost of living. 

Solar Provider and System Requirements

Solar Providers (Business)

Solar Providers will be required to be a signatory to the CEC Approved Solar Retailer program or equivalent ACCC code of conduct. This will be mandatory from 1st of November 2019 for all retailers taking part in the program and mandatory from 1st of July for the top 150 retailers (determined by sales volume).


  • There will be stricter testing of PV inverters so they do not remain live (or ‘islanded’) in the event of blackout
  • Inverters will need to be able to provide ‘Volt-VAr’ and ‘Volt-Watt’ response modes to help maintain network voltage within correct levels while allowing solar electricity to be exported.

As well as the Federal Government SRES subsidy South Australian residents have access to the Home Battery Scheme and Virtual Power Plant.

Home Battery Scheme

Households in South Australia can access subsidies up to $6000 to help pay for the installation of home battery systems as an additional component to their current or new solar PV system.

Additional finance is also available through RateSetter to help households pay for the remaining balance of the subsidised battery and new or additional solar system if required.

The subsidy is available to all South Australians who own or occupy a home in South Australia and will be calculated on the kilowatt-hour capacity of the battery purchased. Energy Concession Holders are eligible for a higher subsidy, ensuring low-income households are supported to access the scheme.

The subsidy is taken off the cost of the home battery system and given to the System Provider once the system is installed at your home.

Home Battery Scheme Subsidy Levels

  • Energy concession holder: $600.00 per kilowatt-hour (kWh)
  • All other households: $500.00 per kilowatt-hour (kWh)

Maximum Subsidy is capped at $6000


  • Customer: Only one subsidy per property
  • Site: Only residential properties are eligible
  • Concession status: Energy concession recipients are eligible for a higher subsidy amount per kwh of battery capacity installed
  • Battery System: Only approved eligible equipment to be installed by a qualified system provide
  • Ownership: The applicant must be the owner of the property or have consent from the owner to install a battery system

Virtual Power Plant

The Virtual Power Plant initiative is open for South Australians to register their interest.
A virtual power plant is created by a network of home solar photovoltaic (PV) and battery systems all working together to generate, store and feed energy back into the grid.
Energy from the home solar PV and battery systems installed will provide electricity for your house.

Who can take part?

Subject to the trials’ success, program financing, and the satisfaction of both Tesla and the government in the final program design, the full program could be rolled out to a further 49,000 properties, including private households.

As a South Australian resident, you can join the Tesla Energy Plan and save $8,201 off the price of Powerwall (inc. GST and the Home Battery Rebate) and receive the lowest energy rates in the state. Learn More.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
