Solar Power Rebates Australia: Federal and State Guide
Many homeowners in Australia are seeking ways to improve home energy efficiency and reduce reliance on the grid. Solar power has become an increasingly popular solution, providing clean and renewable energy for everyday use. To support this transition, the government offers solar power rebates to help lower upfront installation costs. This article will explore which solar rebates are still available in Australia today and how homeowners can make the most of them to save on energy bills, increase energy independence, and contribute to a greener future.
Federal Solar Power Rebates Available in Australia
Federal support gives most Australian households the first layer of savings when they install eligible rooftop solar or a home battery. These programs usually reduce the upfront cost through certificates or installer discounts, rather than sending a cash payment directly to the homeowner.
Small-scale Renewable Energy Scheme (SRES)
The Small-scale Renewable Energy Scheme, or SRES, helps reduce the upfront cost of eligible rooftop solar systems through Small-scale Technology Certificates, known as STCs. When a household installs an eligible solar PV system, the system can create STCs based on its size, location and expected renewable energy generation.
The value of STCs reduces over time as the scheme moves towards its planned end in 2030. For households already planning to install solar, acting earlier can often provide a stronger upfront discount than waiting, as long as the system suits the home and the installer meets the required standards.
To qualify, a solar system generally needs to:
Fit within the small-scale system rules, usually no more than 100 kW.
Use approved solar panels and inverters.
Meet Australian standards and local electrical safety rules.
Use a properly accredited designer and installer.
Follow federal, state, territory and local requirements.
Show the STC discount clearly in the quote.
Before signing, check whether the quote lists the system cost, the STC discount and the final out-of-pocket price separately. This makes it easier to compare offers from different solar retailers.
Cheaper Home Batteries Program
The Cheaper Home Batteries Program is the main federal battery support available to Australian households in 2026. It started on 1 July 2025 and helps reduce the upfront cost of eligible home batteries connected to new or existing rooftop solar.
The program runs through the SRES and STC systems. For most households, an accredited solar or battery installer applies the discount in the quote and handles the certificate process.
Eligible battery systems generally need a nominal capacity between 5 kWh and 100 kWh. The rebate calculation only applies to the first 50 kWh of usable battery capacity. The battery also needs to use approved products and connect to rooftop solar.
From 1 May 2026, the battery support calculation changed. The STC factor now tapers by usable capacity:
0 kWh to 14 kWh: 100% STC factor.
Above 14 kWh to 28 kWh: 60% STC factor for that portion.
Above 28 kWh to 50 kWh: 15% STC factor for that portion.
This does not mean larger batteries receive no support. It means a larger battery receives different levels of support across different portions of its usable capacity. For example, a 10 kWh battery sits within the first band, while a larger battery may receive a lower STC factor for the capacity above 14 kWh. If your household already has, or plans to install a 10 kW solar system, the battery size should still be based on your evening usage, backup needs and available solar generation, rather than the largest rebate amount.
The rebate value will continue to decline towards 2030, so households considering a battery should compare quotes and confirm which installation date and STC rate the installer has used.
How to Access Battery Rebates
Most households access the Cheaper Home Batteries Program through an accredited solar or battery installer. The installer usually applies the discount upfront and manages the STC process.
Before accepting a quote, check that:
The battery qualifies for the program.
The battery and inverter appear on the relevant approved product lists.
The installer has the right accreditation.
The system connects to new or existing rooftop solar.
The quote shows the discount and final price clearly.
The battery size matches your household usage, not only the largest rebate amount.

What to Check Before Claiming Solar Power Rebates
Know What Type of Support You Are Comparing
Not every solar incentive reduces the upfront installation cost. Some programs work as rebates, while others work as low-interest loans, feed-in credits or VPP payments.
Before comparing offers, separate them clearly:
Solar panel rebates can reduce the upfront cost for eligible households.
Battery rebates can lower the cost of an approved battery installation.
Loans can reduce upfront pressure, but they still need to be repaid.
Feed-in tariffs credit exported solar electricity after the system starts operating.
VPP payments or credits depend on battery participation and provider terms.
Confirm Eligibility Before Installation
Many solar power rebates require eligibility checks before installation begins. Depending on the program, eligibility may depend on:
your state or territory
household income
concession card status
property type
owner-occupier or rental status
apartment or strata approval
battery size
electricity retailer or network area
whether the program still has available funding
If the rebate requires pre-approval, do not assume it can be applied after the system has already been installed.
Check Approved Products and Accredited Installers Where Required
Some solar and battery rebates only apply when the system uses approved products and qualified installers. This is especially important for federal support, battery rebates and programs linked to safety or grid requirements.
Before signing a quote, check whether the program requires:
approved solar panels, batteries or inverters
an accredited designer or installer
a minimum or maximum system size
connection to an existing or new rooftop solar system
battery compatibility with VPP participation
compliance with local electrical and grid connection rules
Not every state or local incentive uses the same product rules, so check the conditions for the specific program you want to use.
Ask How the Rebate Appears in Your Quote
A clear solar quote should show the system cost, rebate or STC discount, and final out-of-pocket price. If the quote only shows one final number, ask the installer to explain what has already been included.
Check whether the quote includes:
the STC discount for rooftop solar
the federal battery discount, if relevant
any state or territory rebate
any council incentive
any VPP incentive
estimated feed-in tariff income
This helps you avoid comparing one quote with upfront discounts against another quote that includes future savings estimates.
Compare Feed-in Tariffs and Electricity Plans Separately
Feed-in tariffs can improve long-term solar savings, but they should be compared separately from rebates. A high feed-in tariff may look attractive, but the overall electricity plan still matters.
When comparing plans, look at:
daily supply charge
usage rate
peak and off-peak rates
feed-in tariff rate
export limits
battery or VPP conditions
contract terms
For many households, the best result comes from using more solar energy at home rather than relying only on exported electricity.
How to Maximise Solar Savings Beyond Rebates
Shift Flexible Loads to Solar Generation Hours
For many Australian households, exporting excess solar to the grid is less valuable than using that power at home. Feed-in tariffs are usually lower than the retail rate you pay to buy electricity from the grid, so solar self-consumption should be part of the savings plan, not an afterthought.
Try moving flexible loads into stronger solar generation hours, especially late morning to mid-afternoon:
run the dishwasher, washing machine or pool pump during the day
charge phones, laptops, tablets and cordless tools while solar output is high
use appliance timers for non-urgent loads
pre-cool living areas before peak evening rates begin
avoid running several high-load appliances at the same time after sunset
This is especially useful for homes on time-of-use tariffs, where evening power can cost more.
Store Excess Solar for Evening Use
With rooftop solar, generation often peaks during the middle of the day, while household demand can rise later in the afternoon and evening. Instead of exporting all unused solar at a lower feed-in tariff, a flexible storage option can help keep part of that energy available for later use. A portable power station can be useful when a household wants backup power without relying only on a fixed home battery.
For flexible home backup, the EcoFlow DELTA 3 Ultra Plus Portable Power Station suits households that want to keep selected essentials running during short outages or peak-rate periods. Its fast solar charging support helps make better use of daytime solar generation, while its expandable design gives households more room to adjust storage around everyday needs.
For broader home backup needs, the EcoFlow DELTA Pro Ultra Whole-home Backup Battery is a strong option for households that want higher-capacity energy storage and reliable whole-home support. With strong solar input, it can recharge efficiently from solar energy and help power essential household needs, reducing dependence on the grid while maximising solar energy utilisation. The EcoFlow app also allows real-time energy monitoring, giving households clearer control over power use and better insights for smarter energy management. By pairing it with the EcoFlow Transfer Switch, it can be integrated as a whole-home backup power source.
Review Electricity Plans and Feed-in Tariffs Regularly
Solar savings can change when retailers update usage rates, feed-in tariffs, daily supply charges or time-of-use periods. A plan with a higher feed-in tariff is not always cheaper overall if the usage rate or daily supply charge is also high. When reviewing a plan, compare:
daily supply charge
peak, shoulder and off-peak usage rates
solar feed-in tariff
export limits
battery or VPP plan conditions
contract period and exit fees
Conclusion
Solar power rebates in Australia provide households with valuable opportunities to reduce the cost of using solar energy. By understanding how federal and state programs work together, homeowners can make informed decisions about when and how to adopt solar. Careful planning and strategic use of available incentives help ensure that households can fully benefit from these programs while maximising long-term savings and energy efficiency.
FAQs
What is the 20% rule for solar panels?
The 20% rule is a practical guideline in the solar industry suggesting that a solar system should be designed to cover about 80% of a household’s total energy consumption, leaving the remaining 20% as a buffer. This ensures that unexpected energy demands or system losses are accounted for, helping to maintain efficiency and reliability. Following this rule allows homeowners to maximise the benefits of solar power while reducing the risk of overproduction or shortages.
Is a 10 kW solar system enough to run a house?
Yes, a 10 kW solar system is generally sufficient to meet the electricity needs of a typical household. It can generate around 35 to 45 kWh of electricity per day, which is significantly higher than the average household consumption of about 15 to 25 kWh per day. However, actual output may vary depending on factors such as geographic location, roof orientation, and seasonal sunlight conditions, but overall it is capable of covering most daily energy usage.
Is investing in solar energy in Australia worth it?
Yes, investing in solar energy in Australia is generally worthwhile. Government programs, such as solar power rebates, help reduce the upfront cost of installation, while solar energy can gradually lower household electricity bills. Pairing solar with energy storage solutions further enhances energy efficiency and flexibility. Beyond financial benefits, solar energy also contributes to reducing carbon emissions, offering significant environmental advantages alongside long-term cost savings.
