Frequently Asked Questions

Find answers to the most common questions about the Cheaper Home Batteries Program, installation, and Alpha ESS solar battery systems.

This federal program offers a 30% discount on the purchase and installation of eligible small-scale battery systems when connected to new or existing rooftop solar panels. The rebate is available to homeowners, small businesses, and community facilities. Batteries must be between 5 kWh and 100 kWh in capacity, with the rebate applying to the first 50 kWh of usable capacity.

The rebate can significantly reduce the upfront cost of installing a battery system. For example:

11–13 kWh systems: Approximately $4,000 off the installation cost.
50 kWh systems: Up to $18,600 in savings.

These savings can help reduce your electricity bills by up to $1,100 annually for households with existing solar panels. If you’re installing both solar panels and a battery, the savings could be as high as $2,300 per year.

You must be a homeowner, small business owner, or part of a community facility.
The battery system must be installed alongside a new or existing rooftop solar system.
The battery must be listed on the Clean Energy Council’s approved list.
Installations must be carried out by approved installers.
Only one rebate per property is allowed.
The program is not means-tested, so it’s available to all eligible property owners.

Choose an Approved Installer: Select a Clean Energy Council-accredited installer who offers eligible battery systems.
Get a Quote: Obtain a detailed quote that includes the cost of the battery system, installation, and any additional fees.
Confirm Eligibility: Ensure the battery system is on the approved list and meets all program requirements.
Apply for the Rebate: Your installer will assist you in applying for the rebate through the Small-scale Renewable Energy Scheme (SRES).
Installation: Once approved, proceed with the installation of your battery system.

The rebate applies to new installations only.
Pre-installed batteries are eligible if they are turned on after July 1, 2025.
The rebate is non-transferable and can only be claimed once per property.
State-based incentives, such as Queensland’s Solar Battery Booster program, may also be available to further reduce costs.
