FEDERAL REBATES & INCENTIVES

Federal Solar Rebate: Government Support for Solar and Batteries

Australia's federal solar rebate helps reduce the upfront cost of eligible rooftop solar through the Small-scale Renewable Energy Scheme and Small-scale Technology Certificates (STCs). Federal support is also available for eligible battery systems through the Cheaper Home Batteries Program, while other programs can support broader household energy upgrades. There is no single fixed rebate amount that applies to every property. The support available depends on the technology, system size, installation date, location and current program requirements. Decarby helps homeowners and businesses understand which federal incentives may apply without allowing the rebate to dictate the system design.

FEDERAL SOLAR REBATE

What Is the Federal Solar Rebate?

The federal solar rebate is the term commonly used for the upfront financial benefit available to eligible small-scale solar installations through Australia’s Small-scale Renewable Energy Scheme (SRES). Eligible systems can create Small-scale Technology Certificates (STCs), whose value is commonly assigned to a registered agent and reflected as an upfront reduction in the installation price.

It is important to understand that this is not one fixed cash payment from the Australian Government.

The number of STCs an eligible solar installation can create depends on factors including the system capacity, installation location, installation date and applicable deeming period. The market value of the certificates also affects the financial benefit ultimately reflected in the installation price.

That is why two solar installations should not automatically be assumed to receive the same dollar benefit simply because both qualify for the federal scheme.

HOW IT WORKS

How the Federal Government Rebate for Solar Works

For eligible small-scale rooftop solar, the primary federal support mechanism is the Small-scale Renewable Energy Scheme.

The scheme allows eligible renewable energy systems to create Small-scale Technology Certificates.

In practice, the process is generally much simpler for the customer than the terminology makes it sound.

Small-scale Renewable Energy Scheme (SRES)

The Small-scale Renewable Energy Scheme, commonly known as the SRES, provides certificate-based financial incentives for eligible small-scale renewable energy installations.

For rooftop solar, eligible installations can create STCs based on the expected renewable electricity generation over the remaining deeming period of the scheme.

For solar systems installed during 2026, the applicable solar deeming period is five years.

The SRES is scheduled to continue reducing toward 2030. As the remaining deeming period becomes shorter, newly installed systems can create fewer certificates.

This means the federal solar rebate available through STCs changes over time rather than remaining at one permanent level.

Small-scale Technology Certificates (STCs)

Most homeowners and businesses do not create and trade their own Small-scale Technology Certificates.

Instead, the system owner commonly assigns the right to create the eligible STCs to a registered agent.

The commercial value of those certificates can then be reflected as an upfront reduction in the price of the eligible solar installation.

This is the mechanism behind what is commonly advertised as a solar installation rebate or federal solar rebate.

The underlying support comes from the SRES and STC framework rather than from a single fixed government cheque.

What Determines Your Solar STC Benefit?

The number and value of STCs associated with an eligible installation can depend on several factors.

For this reason, an advertised government rebate on solar should not automatically be applied to every property.

The actual project needs to be assessed against the rules and values applying when the installation proceeds.

  • Solar system capacity
  • Installation location
  • Installation date
  • Applicable deeming period
  • Current certificate value
  • Equipment and installation eligibility

FEDERAL BATTERY SUPPORT

Federal Government Solar Battery Rebate: Cheaper Home Batteries Program

Federal support is not limited to rooftop solar.

The Australian Government’s Cheaper Home Batteries Program provides an upfront discount for eligible small-scale battery installations.

For eligible Australian households, businesses and community organisations, the program is designed to reduce the upfront cost of qualifying battery storage.

The program works through the Small-scale Renewable Energy Scheme and STC framework rather than through a separate cash payment made directly to every customer.

Federal battery support by usable capacity, from 1 May 2026
Usable battery capacityShare of the applicable STC factor
0–14 kWh100% of the applicable STC factor
Above 14 kWh and up to 28 kWh60% of the applicable STC factor
Above 28 kWh and up to 50 kWh15% of the applicable STC factor

For batteries installed between May and December 2026, the applicable federal battery STC factor is 6.8. Only the first 50 kWh of usable battery capacity can receive battery STCs.

Who May Be Eligible?

To qualify under the program, battery systems generally need to meet current capacity, solar-connection, equipment and installation requirements.

STCs are available for the first 50 kWh of usable battery capacity.

Eligibility should always be confirmed against the current program rules before the incentive is included in the expected project cost.

  • Nominal capacity between 5 kWh and 100 kWh
  • Connection to new or existing solar PV
  • Relevant approved-product requirements
  • Installation by an appropriately accredited installer
  • Applicable technical and safety requirements

How the 2026 Battery Support Is Calculated

The federal government solar battery rebate changed substantially on 1 May 2026.

Current rules from
1 May 2026
May–December 2026 STC factor
6.8
STC support limited to
First 50 kWh of usable capacity

For batteries installed between May and December 2026, the applicable STC factor is 6.8, with support tapering as usable battery capacity increases.

Only the first 50 kWh of usable battery capacity can receive battery STCs.

This means that increasing battery capacity does not produce a proportional increase in federal support.

Why Battery Size Still Needs Proper Engineering

A larger battery may receive a greater total incentive, but that does not automatically make it the right battery for the property.

The available incentive can then improve the economics of a battery system that already makes technical and financial sense.

The rebate should support the design. It should not determine it.

  • How much solar the property generates
  • How much electricity is exported
  • Evening and overnight consumption
  • Electricity tariffs
  • Inverter capacity
  • Backup requirements
  • EV charging
  • Future electrification

AT A GLANCE

Federal Solar and Energy Support at a Glance

Federal energy support is delivered through different mechanisms. Some programs are current, one has ended, and one expansion has been announced but is not yet in force.

FEDERAL FINANCE SUPPORT

Household Energy Upgrades Fund

Not every form of federal energy support is a rebate.

The Australian Government has committed $1 billion through the Clean Energy Finance Corporation’s Household Energy Upgrades Fund (HEUF).

The fund works with participating banks and finance providers to make discounted green finance available for eligible household energy improvements.

Depending on the participating provider, eligible technologies may include rooftop solar, household batteries, heat pumps, energy-efficient heating and cooling, insulation, induction cooktops, EV chargers and home energy-management technology.

The Clean Energy Finance Corporation does not provide these loans directly to individual households. Participating lenders provide the finance and determine their own lending eligibility.

ENDED PROGRAM

What Happened to the Federal Electricity Bill Rebate?

Households researching government solar rebates and other Australian energy support may still encounter older information about direct federal electricity-bill payments.

The Australian Government’s Energy Bill Relief Fund provided direct electricity-bill support to households and eligible small businesses over several stages.

The final extension provided up to $150 in electricity-bill relief between July and December 2025.

The program ended on 31 December 2025.

There is therefore no continuing universal federal electricity-bill rebate under that program in 2026.

That does not mean federal energy support has disappeared. Current programs increasingly focus on reducing the cost of solar, battery storage, energy efficiency and household electrification, or improving access to discounted finance.

Eligible customers may also have access to separate ACT, NSW or other state and territory support depending on their location and circumstances.

COMMERCIAL SOLAR

Federal Support for Larger Commercial Solar Is Expanding

Federal solar support is also evolving for larger Australian businesses.

In August 2026, the Australian Government announced plans to expand the Small-scale Renewable Energy Scheme to eligible mid-scale solar PV systems above 100 kW and up to 1 MW.

The announced intention is for eligible installations to access the expanded arrangements from 1 October 2026, subject to the required regulations being in place.

This could be relevant to warehouses, logistics facilities, farms, agricultural processing facilities, schools, hospitals, community facilities and other commercial and industrial properties.

Solar PV systems above 100 kW have traditionally sat within the Large-scale Renewable Energy Target framework rather than receiving STCs through the SRES.

Under the announced expansion, qualifying mid-scale systems would be able to create STCs based on a five-year deeming period through 2030.

This has the potential to simplify the federal incentive proposition for businesses considering larger rooftop solar installations.

However, announced support should not be treated as automatically available until the applicable requirements are in force.

Decarby assesses commercial project eligibility against the rules applying when the project is ready to proceed.

PROGRAM TYPES

How Government Solar Rebates Actually Work

The word “rebate” is used to describe several different types of government energy support. That can make comparing programs confusing.

There is no single government solar energy rebate that covers every solar, battery or electrification project in Australia.

Instead, support can be delivered through several different mechanisms.

Certificate-Based Solar Incentives

Eligible solar installations can create Small-scale Technology Certificates through the SRES.

The value of those certificates is commonly reflected as an upfront reduction in the installation price.

Battery Incentives

The Cheaper Home Batteries Program also operates through the STC framework and provides upfront support for qualifying battery systems.

The amount depends on the eligible battery capacity and the applicable STC rules at the time of installation.

Discounted Finance

The Household Energy Upgrades Fund supports discounted finance through participating lenders rather than providing a direct cash rebate.

This can help eligible households finance a broader range of energy upgrades.

Targeted Government Programs

Other federal, state and territory programs may apply to particular technologies, household circumstances, businesses or property types.

The most useful question is therefore not simply “How much is the rebate?” It is “Which current programs may apply to this property and this energy project?”

COMBINING SUPPORT

Can Federal and State Solar Incentives Work Together?

Potentially.

Australian energy policy operates across federal, state and territory governments, so an eligible project may sometimes access support from more than one level of government.

Depending on the current requirements, a project could potentially combine federal solar STCs, federal battery support, an eligible ACT or NSW incentive and relevant discounted finance.

However, government solar rebates and incentives should never simply be added together using advertised headline figures.

Each program can have its own requirements covering eligible equipment, installation dates, system size, installer accreditation, previous installations, certificates, property type, concession status, network connection and previous incentive claims.

Some programs can operate together. Others restrict double claiming.

Decarby therefore checks the current requirements relevant to the actual project rather than assuming every available incentive can be stacked.

DESIGN FIRST

The Rebate Comes After the Energy Strategy

A federal solar rebate can improve the financial case for an energy upgrade. It should not determine what you install.

Consider a household with an existing 6.6 kW solar system that exports significant electricity during the day. A battery may make sense. But the right capacity depends on how much surplus solar is available, how much electricity the household consumes after sunset, its tariff, and whether future loads such as an EV or heat pump are planned.

Installing the largest eligible battery simply because government support is available may result in capacity that is rarely used.

Solar works the same way. The right solar system should consider:

  • Electricity consumption
  • Daytime load
  • Roof space
  • Orientation
  • Shading
  • Network export limits
  • Electricity tariffs
  • Existing electrical infrastructure
  • Expected future electricity use

In short:The incentive supports the investment. It does not replace the engineering.

WHOLE-HOME ENERGY

More Than Solar: Planning the Electrified Home

Federal energy support increasingly reflects the fact that household energy is becoming an interconnected system.

Solar can generate electricity during the day. A battery can store excess production. Heat pump hot water can use electricity more efficiently than conventional electric resistance heating. Reverse-cycle air conditioning can provide efficient electric heating and cooling. Induction cooking can replace gas cooking. An EV can shift part of household transport energy demand onto electricity.

Planning these technologies together changes how solar and battery systems should be sized. It can also change how government support should be evaluated.

Instead of choosing an individual product simply because it has the largest incentive, Decarby considers how these technologies can work together over the life of the property.

OUR PROCESS

From Federal Solar Rebate to a Properly Designed System

  1. Tell Us About Your Property

    We start with where the property is located, whether it is residential or commercial, your existing energy systems and what you are considering installing. Those details help determine which federal programs may be worth reviewing for the project.

  2. Understand Your Electricity Use

    We assess how much electricity you use, when you use it, existing solar generation and likely future loads. A clearer usage profile supports system sizing before any incentive figures are relied upon.

  3. Identify Current Support

    We check the federal programs relevant to the proposed project and identify applicable state or territory support where appropriate. This step separates current incentives from announced changes or programs that no longer apply.

  4. Confirm Eligibility

    Equipment, installation, system size and other program requirements are reviewed before an incentive is treated as available. Eligibility still depends on the rules of each government program and the specifics of the proposed installation.

  5. Design the System

    The system is designed around performance and actual energy requirements. Government support is then applied to the appropriate solution rather than driving the design itself.

  6. Review a Transparent Proposal

    You can see the recommended system, project cost and how relevant incentives affect the investment. The proposal is intended to make the underlying recommendation and any applicable support clear before you decide.

FREQUENTLY ASKED QUESTIONS

Federal Solar Rebate FAQs

What is the federal solar rebate in Australia?

The federal solar rebate is the term commonly used for the financial benefit eligible small-scale solar installations receive through Australia’s Small-scale Renewable Energy Scheme. Eligible solar PV systems can create Small-scale Technology Certificates, or STCs. Their value is commonly assigned to a registered agent and reflected as an upfront reduction in the installation price. It is therefore not a single fixed cash payment made directly to every solar customer.

How does the federal solar rebate work?

Eligible small-scale solar installations can create STCs under the Small-scale Renewable Energy Scheme. The number of certificates depends on factors including system capacity, installation location, installation date and the applicable deeming period. Most customers assign the right to create those certificates to a registered agent. The commercial value of the STCs can then be reflected as an upfront reduction in the solar installation price.

Is there a federal government rebate for solar panels?

Yes, although the main federal government rebate for solar panels is technically a certificate-based incentive rather than a conventional cash rebate. Eligible small-scale solar PV systems can create STCs under the SRES, and the value of those certificates is commonly reflected as an upfront installation discount.

How much is the federal solar rebate in 2026?

There is no single fixed dollar value for the federal solar rebate. The number of STCs an eligible solar system can create depends on the system capacity, installation location, installation date and applicable deeming period. The certificate value also affects the financial benefit reflected in the installation price. For solar systems installed during 2026, the applicable solar deeming period is five years.

How are solar STCs calculated?

The number of Small-scale Technology Certificates associated with an eligible solar installation depends on factors including system capacity, location, installation date and the remaining deeming period under the SRES. The applicable certificate value can also change, so the financial benefit should be assessed for the actual system and installation timing.

Is the federal solar rebate a cash payment?

Not usually. For eligible small-scale rooftop solar, the main federal incentive operates through Small-scale Technology Certificates rather than a direct universal cash payment. Customers commonly assign the right to create their eligible STCs to a registered agent, with the value reflected as an upfront reduction in the installation price.

What is the federal government solar battery rebate?

The Australian Government’s Cheaper Home Batteries Program provides upfront support for eligible small-scale battery installations through the STC framework. Eligible households, businesses and community organisations may receive support for qualifying batteries connected to new or existing solar, subject to current capacity, equipment, installation and technical requirements. The amount is not one fixed dollar figure.

How much government support can I receive for a solar battery?

The Cheaper Home Batteries Program is designed to provide a substantial upfront discount for eligible battery installations, but there is no single fixed dollar amount. The number of STCs depends on usable battery capacity and the applicable STC factor when the battery is installed. From 1 May 2026, support tapers as battery capacity increases. The first 14 kWh receives the full applicable factor, capacity above 14 kWh and up to 28 kWh receives 60%, and capacity above 28 kWh and up to 50 kWh receives 15%. Only the first 50 kWh of usable battery capacity can receive battery STCs.

Can I get the federal battery rebate if I already have solar?

Potentially, yes. An eligible battery can be connected to either a new or an existing qualifying solar PV system. The battery still needs to satisfy the current program requirements, including eligible capacity, approved equipment, installation and technical requirements.

Do I have to apply directly to the Australian Government for the battery rebate?

Generally, no. Consumers do not normally lodge a direct application with the Department of Climate Change, Energy, the Environment and Water or the Clean Energy Regulator for the battery discount. The support operates through STCs. Where the owner assigns the eligible certificate rights to a registered agent, their value can be provided through the commercial arrangement, commonly as an upfront discount.

Is there still a federal electricity bill rebate in 2026?

The nationwide Energy Bill Relief Fund has ended. Its final extension provided eligible households and small businesses with up to $150 of electricity-bill relief between July and December 2025, and the program ended on 31 December 2025. Separate state or territory electricity concessions may still be available depending on the customer’s circumstances and location.

What is the Household Energy Upgrades Fund?

The Household Energy Upgrades Fund is a $1 billion Clean Energy Finance Corporation initiative supporting discounted finance for eligible household energy improvements. Finance is delivered through participating banks and non-bank lenders rather than directly by the Australian Government. Eligible technologies can include solar, batteries, heat pumps, insulation, energy-efficient heating and cooling, induction cooktops and EV chargers, depending on the participating lender.

Can I combine federal rebates with ACT or NSW incentives?

Potentially. Some federal incentives can operate alongside eligible state or territory support when the requirements of each program are satisfied. For example, an eligible battery project may potentially receive federal support while also qualifying for a separate NSW incentive. ACT households may similarly qualify for targeted territory programs alongside applicable federal solar or battery support. Combination rules vary, however, and some programs restrict double claiming. Eligibility should therefore be checked for the actual project.

Are businesses eligible for federal solar and battery support?

Yes, subject to the requirements of the relevant program. The SRES is available to eligible households and businesses installing qualifying small-scale renewable energy systems. The Cheaper Home Batteries Program can also apply to eligible businesses and community organisations, subject to the battery, solar, equipment and installation requirements. Larger commercial solar projects should be assessed against the specific federal rules applying to their system size and installation date.

Do government rebates determine the best solar or battery size?

No. Government support should improve the economics of an appropriately designed system rather than determine its capacity. Solar sizing should consider electricity consumption, roof conditions, shading, network export limitations and future electrical demand. Battery sizing should consider solar surplus, evening consumption, tariffs, inverter capacity, backup requirements and expected battery use.

Are government solar rebates guaranteed?

No. Eligibility depends on the requirements applying to the individual program. Factors can include installation date, equipment eligibility, system capacity, property type, installer accreditation, technical standards, existing equipment and previous incentive claims. Government programs can also change over time.

Will federal solar incentives decrease over time?

Some federal incentives reduce over time. The Small-scale Renewable Energy Scheme is scheduled to run until 2030, and the solar deeming period reduces each year. Battery STC factors under the Cheaper Home Batteries Program also decline according to the applicable program schedule and are reviewed periodically. This does not necessarily mean a customer should install immediately simply to capture a larger incentive. The project still needs to make technical and financial sense.

Can Decarby help me understand which federal solar rebates may apply?

Yes. Decarby can help identify relevant federal solar, battery and household energy incentives and explain how they may apply to a proposed project. Where appropriate, we also consider relevant ACT and NSW programs because state and territory support may operate alongside federal incentives. Eligibility remains subject to the requirements of the individual program. Our role is to help you understand those options while ensuring the system is designed around the property’s actual energy requirements.
