CEC accreditation for Perth solar installers: why it matters
In Western Australia, solar panels must be installed by a CEC-accredited installer to qualify for STCs and DEBS. Here's what CEC accreditation means and how to verify your installer.

When getting solar quotes in Perth, you'll see "CEC-accredited" on almost every installer's materials. But what does this actually mean, why does it matter, and how do you verify it? Here's a plain-English guide.
What is CEC accreditation?
The Clean Energy Council (CEC) is Australia's peak renewable energy industry body. CEC accreditation for solar installers means the installer (or the supervising licensee at the company) has:
- Completed the CEC's nationally recognised training in solar PV system design and installation
- Demonstrated competency in AS/NZS 3000 wiring rules and AS4777.2 (grid-connected inverter requirements)
- Holds a current electrical contractor's licence in Western Australia (required for all electrical work under WA law)
- Maintains annual continuing professional development (CPD) requirements to keep accreditation current
CEC accreditation is separate from a general electrician's licence. Not all licensed electricians are CEC-accredited for solar — CEC accreditation requires specific solar training and assessment.
Why CEC accreditation is required for STCs and DEBS
Two critical financial benefits of Perth solar require CEC-accredited installation:
Small-scale Technology Certificates (STCs): The federal rebate that reduces your upfront solar cost by $2,000–$4,000 (depending on system size and zone) is only available if the system is designed and installed by a CEC-accredited installer or supervisor. Non-accredited installation = no STCs, no rebate.
Synergy DEBS (Distributed Energy Buyback Scheme): Synergy will only grant DEBS export credits if the solar system was installed by a CEC-accredited installer and the appropriate network connection approvals (Western Power NCN) were obtained. A system installed outside these requirements cannot access DEBS.
In practice, no legitimate Perth solar installer operates outside CEC accreditation — the rebate requirement means customers wouldn't buy from them. But it's worth verifying, especially when comparing very low-priced quotes.
How to verify CEC accreditation
The CEC maintains a public register of accredited solar installers. You can verify any installer by:
- Visiting the CEC website (cleanenergycouncil.org.au) and using the "Find an accredited installer" search tool
- Searching the installer company or the specific installer's name
- The register shows accreditation status and expiry date
What to check:
- The installer is listed as "accredited" (not "expired" or "suspended")
- Their accreditation type covers solar PV (some accreditations are for solar hot water only)
- The accreditation is in the name of the supervising installer at the company, not just a generic company listing
If a company's accreditation is expired or can't be found in the register, that's a significant red flag. Legitimate installers maintain current accreditation because losing it means losing access to all STC processing.
CEC "Approved Retailer" vs "Accredited Installer"
The CEC has two relevant designations that are sometimes confused:
CEC Accredited Installer: The individual or supervising licensee who performs the physical installation. This is the mandatory designation required for STCs and DEBS.
CEC Approved Solar Retailer: A business that has signed the CEC's Solar Retailer Code of Conduct — a voluntary consumer protection commitment covering fair sales practices, accurate representations, and complaint handling. This is not required by law but is a positive indicator.
Some companies are both; some are only accredited installers. A company that is an Approved Retailer is held to higher standards on sales conduct and product claims.
The difference between installer and designer
Larger solar systems (typically over 10kW) require a CEC-accredited designer to certify the system design, separate from the accredited installer doing the installation work. For residential installations, the same person often holds both accreditations, but for commercial or complex residential projects, the design and installation roles may be separate.
When reviewing a quote, look for:
- Who is the accredited installer? (Must supervise the physical work)
- Who signed off the design? (Must be CEC-accredited for the system size)
For a standard 6.6–13.3kW residential system, one accredited installer/designer typically covers both roles.
WA-specific electrical requirements
CEC accreditation is a national standard, but Western Australian electrical work must also comply with WA state requirements:
- Electrical contractor's licence: The company doing electrical work must hold a WA electrical contractor's licence (Electrical Licensing Board — ELB)
- Electrical Certificate of Compliance (ECC): Post-installation, the licensed electrician must submit an ECC to Western Power
- Western Power NCN: The grid connection requires Network Connection Notice approval from Western Power
A CEC-accredited installer from another state who doesn't hold a WA electrical contractor's licence cannot legally install solar in WA. When comparing quotes, confirm the installer is licensed in WA — not just CEC-accredited nationally.
Red flags to watch for
- Quote with no mention of STC assignment: Legitimate quotes include an "STC assignment" that shows the rebate is built into the price. No STC assignment mention could mean the installer is not CEC-accredited (or the quote excludes the rebate, which is unusual and should be clarified).
- Price significantly below all other quotes with no explanation: If one quote is 40% below others, it may reflect lower-quality panels, unlicensed labour, or no STC processing.
- Resistance to providing CEC accreditation number: Any legitimate installer will readily share their CEC number for verification.
- No Western Power NCN discussion: A legitimate Perth installer will explain the NCN process, timeline, and handle the application. Avoiding this topic is a concern.
CEC accreditation is mandatory for Perth solar STCs and DEBS eligibility — verify via the CEC's public register before signing any contract. All legitimate Perth installers are CEC-accredited; if an installer can't confirm their accreditation number, treat it as a serious concern.
