CEC Approved Retailer vs Approved Installer: What It Means for Perth Solar Buyers in 2026

TL;DR: A CEC Approved Installer is the licensed electrician who physically wires your solar system — required by law for any STC-eligible install in Australia. A CEC Approved Retailer is the company that sells, designs, supplies, warrants, and stands behind the system — a voluntary standard committing to the Solar Retailer Code of Conduct. In Perth, you want both: the retailer covers the sales process, the warranty, and the long-term relationship; the installer covers the on-the-day workmanship. Many “solar companies” in Perth are not CEC Approved Retailers — verifying status before signing is the most important consumer-protection step.

What is the CEC?

The Clean Energy Council (CEC) is the peak body for Australia’s clean energy industry. It administers two separate accreditation programs that often get conflated by sales pitches: one for the businesses that sell solar (Retailer accreditation), and one for the individual electricians and businesses that install solar (Installer accreditation). They cover different things and apply to different parties in any solar transaction.

CEC Approved Installer (the legal minimum)

The installer accreditation is a legal requirement for any grid-connected solar installation in Australia that claims STC rebates (effectively every residential install). It’s held by individual electricians, not companies, and requires:

• Current electrical licence in the relevant state
• Completion of CEC-accredited solar PV course
• Annual continuing professional development hours
• Public liability insurance ($5M minimum)
• Adherence to AS/NZS 5033 and 4777 standards

Every solar install paperwork-signed under STC rebate must list the CEC Installer ID. Without this, your system isn’t legal, isn’t rebate-eligible, and isn’t insurable.

CEC Approved Retailer (the consumer-protection layer)

The retailer accreditation is voluntary and held by the company selling the system. It’s the consumer-protection layer that goes well beyond legal minimums. A CEC Approved Retailer commits to the Solar Retailer Code of Conduct, which is endorsed by the Australian Competition and Consumer Commission (ACCC). Specific commitments include:

• Minimum 5-year whole-of-system workmanship warranty (most non-approved retailers offer 1–2 years)
• Maximum 14-day cooling-off period for any signed contract
• Transparent itemised pricing with no hidden fees
• Honest performance estimates based on actual roof orientation and location
• Documented complaints process with escalation to the CEC if unresolved
• Use of accredited installers for every system
• Authorisation to handle STC paperwork on the customer’s behalf
• $5M public liability + $2M professional indemnity insurance minimums
