There is no single Australia-wide package rebate with the same value for everyone. Depending on the installation date and your circumstances, an eligible solar system may receive Small-scale Technology Certificates (STCs), while an eligible battery may qualify for the federal Cheaper Home Batteries Program, subject to its rules and an approved installer. Your state or territory may also offer additional assistance. Check current details at energy.gov.au and your state government website, then request an itemised quote showing each discount; final eligibility is determined under the relevant program rules.
