What is it?
The Cheaper Home Batteries Program is a federal incentive that reduces the upfront cost of an eligible home battery installed with new or existing rooftop solar. It works through small-scale technology certificates (STCs) — the same certificate system that has discounted rooftop solar for years.
You don’t usually apply for anything yourself. Your installer creates the certificates when the battery is installed, sells them, and takes their value off your price.
How much is the discount?
The number of certificates depends on the battery’s usable capacity and the year it’s installed. From 1 May 2026 the discount is tiered by size:
- First 14 kWh of usable capacity — the full certificate factor.
- 14 to 28 kWh — 60% of the factor.
- 28 to 50 kWh — 15% of the factor.
The dollar value also depends on the market price of certificates, which moves over time. That’s why two installers can show slightly different discounts for the same battery.
Installation date matters. The rules in force on the day the battery is installed apply — not the day you sign. If timing affects your discount, get the installation date in writing.
Who is eligible?
In general, the battery must be installed with new or existing rooftop solar, be an eligible product, and be installed by an appropriately accredited installer. Detailed rules are set by the Clean Energy Regulator, so ask your installer to confirm eligibility on the quote.
What to check on your quote
- The battery’s usable capacity (kWh) and continuous power (kW).
- The number of certificates claimed and their dollar value, as a separate line.
- The planned installation date.
- Whether any state incentive is included, and its conditions.
- The installer’s accreditation for battery installation.
Can I combine it with state incentives?
Often, yes. For example, NSW offers battery incentives through its Peak Demand Reduction Scheme. Each program has its own rules, so check both. Our battery rebates guide lists current programs by state.

The program is for batteries installed with new or existing rooftop solar. Check the current rules with your installer.
