You use power after sunset
Batteries are strongest when your household can use stored solar energy during evening peak periods.
Solar battery guide 2026
Compare solar battery quotes with rebate clarity.
Learn whether a battery makes sense for your home, how the current federal battery discount is calculated, and what to compare before choosing an installer.
Compare up to 3 quotes and ask installers to separate battery cost, STC discount, usable-capacity tier, backup hardware, and estimated savings.

Battery fit
A battery works best when it matches how your home uses power.
The right system depends on solar exports, evening consumption, blackout expectations, tariff structure, and whether you want to join a virtual power plant.
Your solar exports are high
If you export a lot during the day, a battery may help shift more of that solar into your own home.
You want blackout backup
Backup is not automatic with every battery quote, so it needs to be specified and priced clearly.
You are considering a VPP
Virtual power plant programs can offer rewards, but they also come with rules worth comparing.
Battery rebate explained
The battery discount should be separated from the solar quote.
Since 1 May 2026, Cheaper Home Batteries Program support is tiered by usable capacity. The highest support applies to the first 14kWh, then steps down above 14kWh and 28kWh, with STCs only available for the first 50kWh of usable capacity.
Current STC factor and usable-capacity tier: 0-14, 14-28, or 28-50kWh
Usable capacity, not just headline capacity
Battery warranty, cycles, and throughput limits

A useful battery quote should separate the installed price, discount, usable storage, backup inclusions, warranty terms, and savings assumptions.
Compare the pathway
Solar-only and solar plus battery solve different problems.
A battery can be valuable, but it is not automatically the best next step for every household. Compare the system type against your usage pattern before you commit.
Lower upfront cost
Solar-only
Often best when you want a simpler system focused on daytime energy savings and quicker payback.
Evening energy use
Solar + battery
Useful when you want to store excess solar, reduce grid reliance, and compare rebate-supported battery options.
Compare before you commit
Ask 3 installers to quote the battery properly.
Compare equipment, usable capacity, current STC tier, backup inclusions, warranty, and estimated savings before choosing a solar battery installer.
What is a Solar Battery?
Solar batteries capture and store the excess energy generated by your solar panels throughout the day, storing it for low light conditions, or for use at your home throughout the night. Overall, residential solar batteries offer a versatile and sustainable solution for homeowners looking to optimise their solar energy systems and enhance their energy resilience.
Benefits of Solar Batteries
- Backup Power: In the event of blackouts or emergencies, solar batteries can provide a reliable backup power source for essential appliances and devices when the system is designed for backup.
- Energy Independence: By storing solar energy, homeowners reduce their reliance on the grid, enhancing energy autonomy and reducing utility bills over time.
- Peak Load Management: Solar batteries enable homeowners to manage their energy consumption more efficiently, reducing peak electricity demand and potentially lowering overall energy costs.
- Environmental Impact: Having solar batteries promotes the use of renewable energy, contributing to lower carbon emissions and environmental sustainability. Particularly for owners of electric vehicles.
Batteries can help you store excess solar energy generated during the day and use more of it at home later.
Are solar batteries worth it?
Australia is undergoing a major shift in its energy landscape, driven by strong rooftop solar adoption and increasing interest in home energy storage. Batteries can make sense for households with high evening energy usage, high daytime solar exports, backup power needs, or an interest in virtual power plant (VPP) programs.
A VPP groups many battery owners together so the operator can manage stored energy across the network and, depending on the program, pass rewards back to participating households. Before joining one, compare the rules, payment structure, battery control settings, and how it affects your savings assumptions.
Are Battery Rebates Available?
At present, the Federal Government and some states across Australia offer financial incentives for battery storage systems.
Federal Government (Australia-wide)
Cheaper Home Batteries Program. From 1 July 2025, the Federal Government's solar battery rebate program supports eligible small-scale battery systems connected to new or existing rooftop solar.
Since 1 May 2026, the program uses tiered support based on usable battery capacity. The highest support applies to the first 14kWh of usable capacity, then steps down for capacity above 14kWh and 28kWh. STCs are only available for the first 50kWh of usable capacity. The final saving depends on the current STC factor, usable capacity, eligibility, provider pricing, installation requirements, and whether extra backup hardware is included.
When comparing quotes, ask the installer to separate the battery price, current STC discount, usable-capacity tier, backup costs, VPP assumptions, and estimated bill savings.
