Why CEC accreditation matters for Perth solar installations
Solar installation in Australia requires CEC (Clean Energy Council) accreditation. This requirement gates your access to STCs, network connection approval, and the WA Battery Scheme. Here's what CEC accreditation means and how to verify your installer.

Every Perth solar installer who connects a system to the grid must be accredited by the Clean Energy Council (CEC). This isn't a voluntary quality mark — it's a regulatory requirement that unlocks STCs, Western Power network connection approval, and the WA Battery Scheme rebate. Here's why it matters and how to check.
What is CEC accreditation?
The Clean Energy Council is the peak industry body for the Australian clean energy sector. CEC accreditation for solar installers means the individual has completed the required training, assessment, and ongoing professional development to design and install grid-connected solar systems to the relevant Australian standards.
What it covers:
- Grid-connected solar photovoltaic systems (the core accreditation, required for residential solar)
- Battery storage systems (separate endorsement, required for battery installations)
Who needs it: The individual electrician who physically installs and signs off on the solar system must hold CEC accreditation. The company name on your quote means less than the accreditation status of the actual installer attending your property.
Why CEC accreditation gates key benefits
STCs (Small-scale Technology Certificates): Your installation must be designed and installed by a CEC-accredited person for the system to create STCs. STCs are typically worth $3,500–$5,000 for a 6.6kW Perth system — the installer applies these as a point-of-sale discount. Without a CEC-accredited installer, you can't access this discount.
Western Power NCN (Network Connection Notice): Western Power requires the NCN to be submitted by a CEC-accredited installer. A non-accredited installation cannot be connected to the Western Power grid.
WA Battery Scheme: Synergy's application process for the $130/kWh battery rebate requires confirmation of CEC accreditation for the installation. Non-accredited installations are not eligible.
Workmanship warranty: CEC-accredited installers are bound by the CEC's Code of Conduct, which requires a minimum 5-year workmanship warranty on installations. Non-accredited contractors are not bound by this standard.
How to verify CEC accreditation
Before signing a contract:
- Ask your installer directly: "What is your CEC accreditation number?"
- Verify on the CEC's public Find an Installer tool (accessible via the Clean Energy Council website)
- Confirm the accreditation covers grid-connected PV and battery storage (if installing a battery)
Checking the certificate: CEC accreditation certificates can be requested from the installer. They show the individual's name, accreditation number, and expiry date (accreditation must be renewed annually with continuing education).
Red flags:
- Installer cannot provide an accreditation number
- Accreditation is in the company's name only (should be in the individual installer's name)
- Accreditation has expired (check the renewal date)
What CEC accreditation doesn't guarantee
CEC accreditation sets a minimum competency baseline — it doesn't guarantee the best installer or the best quote.
What it doesn't screen for:
- Quality of panels and inverter brands chosen
- System design decisions (orientation, string configuration, shading analysis)
- Customer service and post-install support
- Business longevity (some CEC-accredited companies have failed, leaving customers without warranty support)
Additional markers of a quality installer:
- Member of the CEC's Approved Solar Retailer program (requires independent audit, not just accreditation)
- Positive reviews with track record of responding to warranty claims
- Local Perth business with physical presence (easier to contact post-install)
- Willing to show you completed installations and provide references
SolarEdge, Enphase, Fronius authorised installers
Some inverter brands (SolarEdge, Enphase, Fronius) have their own additional installer authorisation programs:
- SolarEdge: SolarEdge Preferred Partner program — requires training on SolarEdge equipment
- Enphase: Enphase Installer Network — requires training on Enphase microinverters and monitoring
- Fronius: Fronius Specialist network — training on Fronius inverters and system design
These brand authorisations are on top of, not instead of, CEC accreditation. For complex installations with brand-specific equipment (e.g. a SolarEdge power optimiser system), using a brand-authorised installer may give better configuration outcomes.
The 2022 solar installation rule changes
From 2022, changes to Australian solar standards (AS/NZS 5033) tightened some installation requirements — including arc fault detection, certain cable routing requirements, and documentation standards. CEC-accredited installers are required to train on and comply with updated standards. If you're comparing quotes for a 2026 installation, all CEC-accredited installers should be complying with current standards.
What to do if you've had a non-accredited installation
If you discover your existing solar installation was done by a non-accredited person:
- You may have missed out on STC rebates (these cannot be claimed retrospectively if the window has closed)
- Your network connection may be non-compliant — Western Power can require removal of a non-compliant connection
- Your workmanship warranty (if any) has no CEC Code of Conduct backing
The path forward typically involves engaging a CEC-accredited installer to inspect the existing installation, identify any compliance issues, and submit appropriate documentation to Western Power. This is a more complex situation than a standard new installation — seek advice from a CEC-accredited installer.
Verifying CEC accreditation before signing takes 5 minutes and protects your access to STCs, network connection, and battery rebates worth thousands of dollars.
