More Australian homeowners are exploring how to store clean solar energy at home — not just generate it. With the introduction of the Australian Government’s Cheaper Home Batteries Program, many households can now access substantial savings of around 30% off the upfront cost of installing a solar battery. But not every home automatically qualifies, and knowing the eligibility criteria before you buy can save you thousands and help you get the most out of your investment.
This guide will walk you through who is eligible, what you must meet to qualify, how the incentives work, and the key decisions you should make before purchasing a home battery.
What Are the New Battery Incentives?
The Australian Government has expanded support for household battery storage through the Cheaper Home Batteries Program. This initiative is designed to make battery systems more affordable by offering a government-funded discount of around 30% on eligible installations.
Rather than a post-installation rebate, this discount is usually delivered upfront at the point of sale by your installer or retailer. The reduced price helps homeowners install batteries alongside new or existing rooftop solar systems, lowering dependence on grid electricity and lowering power bills.
Who Qualifies for the Government Battery Incentive?
1. Your Solar Battery Must Meet Size Criteria
To be eligible for the government discount:
- The battery must have a nominal capacity between 5 kWh and 100 kWh.
- Only the first 50 kWh of usable capacity is eligible for small-scale technology certificates (STCs), which are the basis for the discount.
The nominal capacity is the total energy the battery can store at full charge, while the usable capacity is the amount you can actually draw for use. This distinction matters because only usable capacity up to the 50 kWh cap earns incentives.
2. Installation Must Be with Solar PV
The Cheaper Home Batteries Program requires the battery to be installed with a new or existing rooftop solar system. That means if your home doesn’t already have solar, you’ll need to include solar panels to unlock the federal discount.
3. Certified Products and Accredited Installers
To be eligible:
- The battery must appear on the SAA approved product list.
- It must be installed by a Solar Accreditation Australia (SAA) installer with appropriate battery accreditation.
- The installation must comply with all electrical safety regulations in your state or territory.
These requirements ensure quality, safety and reliability of systems supported under the scheme.
4. One Eligible System per Premises
Only one battery system at a residential premises can claim this particular federal incentive. That means if you already have a battery system supported by the program, adding another later won’t attract another federal discount.
How the Incentive Works in Practice?
The discount is delivered through the Small-scale Renewable Energy Scheme (SRES) using small-scale technology certificates (STCs). An installer typically reduces your upfront cost by assigning their rights to the STCs in exchange for the discount.
In 2025, the rate is approximately 9.3 STCs per kWh of usable capacity — roughly equating to a 30% price reduction on the battery component.
Because electricity and battery technology costs are expected to fall over time, the size of this discount will be reviewed and will gradually decrease until 2030.
State and Local Incentives — Bonus Savings
While this blog focuses on the federal eligibility rules, some states and territories may offer additional incentives for batteries or for joining a Virtual Power Plant (VPP). For example, past NSW programs offered up to $1,500 for VPP participation — though such schemes evolve over time.
Before purchasing, check with your local energy authority or speak with Prosolar Global’s expert team to see if your state offers stacked incentives.
Tips Before You Buy
1. Check Your Roof and Solar Setup
Since eligibility links to your rooftop PV system, make sure your existing solar is adequate. If you’re installing solar and a battery, plan the system together for maximum benefit.
2. Choose a Solar Accreditation Australia (SAA)-Approved Battery
Ask your installer to show you the SAA-approved product list before signing a contract. Batteries not on this list won’t be eligible for federal incentives.
3. Understand Future Incentive Changes
From 1 May 2026, the structure of incentives may change to maintain an almost 30% discount across different battery sizes — meaning some batteries could receive tiered rebate rates depending on capacity.
4. Consider Virtual Power Plants (VPPs)
Many battery systems can participate in VPPs, where you can earn additional payments by exporting power back to the grid at peak times. Prosolar Global can advise whether this makes sense for your household.
Frequently Asked Questions (FAQ)
Q1: What is the minimum battery size that is eligible for home battery incentives?
A1: To qualify, your battery must have a nominal capacity of at least 5 kWh and be installed with rooftop solar.
Q2: Can renters claim the battery incentive?
A2: Yes — renters can be eligible if the installation meets the eligibility criteria and the property owner consents. Federal incentives are tied to the installation and system standards, not income.
Q3: Does my existing solar system have to be new?
A3: No — the battery can be installed with existing rooftop solar and still qualify for the incentive.
Q4: Can I install more than one battery per home and get incentives for both?
A4: No — only one eligible battery system per premises can attract the federal discount under this program.
Q5: Will the battery incentive be around forever?
A5: The Cheaper Home Batteries Program is designed to run until 2030, with the value of incentives reducing over time as battery costs fall.
Conclusion
If you’re considering adding battery storage to your solar system — or installing solar and batteries together for the first time — the home battery incentives now available in Australia can significantly reduce upfront costs. But not every home automatically qualifies: you must understand eligibility rules around capacity, product standards, installation requirements, and how the incentive is delivered.
Prosolar Global can help you assess eligibility, design an optimised system, and connect you with SAA accredited installers to ensure you maximise your savings and energy independence.
