Check the installer’s current Clean Energy Council accreditation and relevant state or territory electrical licence before signing a contract. Ask for an itemised quote covering system design, panels, inverter, installation, warranties, approvals and any Small-scale Technology Certificate (STC) discount. You can verify accreditation through the Clean Energy Council’s official installer directory, but accreditation does not replace checking the business’s experience, insurance and reviews. For questions about rebates or STCs, confirm the latest requirements on energy.gov.au or with the installer.
