The Cheaper Home Batteries Program is the battery stream of the Small-scale Renewable Energy Scheme. It covers small-scale batteries with a usable capacity between 5 and 100 kilowatt-hours that are connected to a new or existing rooftop solar PV system. Both the battery and the installation must meet program rules: batteries need to be on the Clean Energy Council's approved list, and the work must be carried out by accredited installers. The program is administered by the Clean Energy Regulator and funded through the creation of small-scale technology certificates, which is the same mechanism that has long discounted rooftop solar panels.
Eligibility basics
Households, businesses and community organisations can all participate. The battery must sit within the 5–100 kWh usable capacity band and be connected to solar PV — a battery installed without solar does not qualify. The system must be installed for permanent use at the premises.
Incentive amounts
The Department of Climate Change, Energy, the Environment and Water describes the incentive as a discount of around 30% on the upfront cost of the battery system. From 1 May 2026 the STC calculation changed: the STC Factor now declines every six months (6.8 for May–December 2026, falling to 2.1 by July–December 2030), and support tapers by battery size — 100% of the factor for systems up to 14 kWh, 60% for 14–28 kWh, and 15% for 28–50 kWh. In December 2025 the federal government announced the program's funding envelope would expand from $2.3 billion to $7.2 billion.
How to apply
There is no consumer application form. The discount is normally applied at the point of sale: you assign your right to create STCs to a registered agent (often your installer or a certificate trader), who applies the value as an upfront price reduction. The Clean Energy Regulator publishes a register of registered agents. Get quotes from accredited installers and confirm the quoted discount reflects the current STC factor.
Important notes
The battery must be CEC-approved and connected to solar PV to qualify. The program stacks with state battery schemes such as Western Australia's Residential Battery Scheme, but state rules differ — check both. The STC factor is reviewed at least annually and declines over time, so earlier installations attract larger discounts. Program details change — verify current rules on the official program page before applying.
