Check your property’s postcode, system size and proposed panels and inverter against the current requirements for Small-scale Technology Certificates (STCs). Compare written quotes that clearly show the rebate or STC discount, total price, warranties, installation details and any ongoing costs. Also check whether your state or territory offers a separate battery or solar incentive, as eligibility and application rules can change. Ask the installer what paperwork they will provide, and verify their accreditation and licence details. Confirm the latest rules with the installer and the relevant government website, such as energy.gov.au.
