What is a CEC accredited installer?
A CEC accredited installer is an individual who holds Clean Energy Council accreditation covering design and/or installation work on grid-connected solar systems and is legally permitted to sign off on systems claiming Small-scale Technology Certificates (STCs) under Australian law.
The Clean Energy Council (CEC) issues accreditation to solar installers across Australia who meet technical and competency standards. To work on grid-connected photovoltaic systems (those feeding power back to the electricity network), an installer must hold either a Design Endorsement, an Installation Endorsement, or both.
This accreditation matters because Australian law requires STCs (the renewable energy credits that reduce a customer's system cost) to be issued only when a CEC accredited installer signs off on the work. Without it, a system cannot legally claim these certificates, which removes much of the financial incentive for households and businesses to install solar.
The Design Endorsement certifies that an installer can size systems, calculate load profiles, and ensure electrical compliance for grid connection. The Installation Endorsement confirms they can physically install equipment, carry out safe switchboard work, and test systems before they go live. Many installers hold both.
In Perth, CEC accreditation is essential for any solar business offering grid-connected installations. The accreditation requires evidence of electrical trade qualifications, ongoing professional development, and adherence to CEC codes of conduct. It is specific to the individual installer, not the company, though businesses employ accredited staff to perform this work legally.
