Look for an installer with current Clean Energy Council (CEC) accreditation and verify their details through the CEC’s official installer directory. CEC accreditation can support eligibility for small-scale technology certificates, but it is not a guarantee of workmanship, pricing or service quality. Compare written quotes, check the installer’s electrical licence, product warranties, workmanship warranty and who will handle grid-connection paperwork. You can also ask your electricity distributor about local requirements before signing, and seek independent advice if you are unsure about the proposed system.
