CEC accreditation is the practical gateway to the Australian solar market. Without it, a system cannot qualify for STCs — the federal incentive that reduces residential and commercial solar installation costs by thousands of dollars. For most installers, CEC accreditation is not optional; it is the commercial baseline.
This guide covers the complete accreditation process, costs, scope differences between installer and designer accreditation, and what to do if your accreditation lapses.
Why CEC Accreditation Matters
CEC accreditation serves two commercial functions:
1. STC eligibility: Under the federal small-scale renewable energy scheme, STCs can only be created for systems installed by CEC-accredited installers. The STC discount is equivalent to $1,000–$4,000 for a typical residential system and $5,000–$30,000+ for larger commercial systems. Without accreditation, the installer cannot offer this discount, making their pricing uncompetitive.
2. DNSP grid connection requirements: Most DNSPs require CEC-accredited installers for grid connection applications. Ausgrid, Endeavour Energy, Energy Queensland, SA Power Networks, and Western Power all reference CEC accreditation in their connection requirements. An unaccredited installer may not be able to submit a valid connection application.
CEC Installer vs Designer Accreditation
| Category | Scope | Who Needs It |
|---|---|---|
| CEC Installer Accreditation | Physical installation — wiring, mounting, electrical connections, commissioning | Any person carrying out solar PV installation work |
| CEC Designer Accreditation | System design — component specification, string sizing, single-line diagrams, design documentation | Person responsible for the system design |
| Both | Required for small residential where same person designs and installs | Most sole-trader residential installers |
For commercial and industrial projects, the designer and installer functions are typically separated. The CEC-accredited designer produces the design documentation; the CEC-accredited installer carries out the physical work.
Eligibility Requirements
To be eligible for CEC installer accreditation, applicants must:
- Hold a current, unrestricted electrical contractor or electrician licence in their state or territory
- This means an A-grade electrician licence (or equivalent) — restricted licences (e.g., appliance service, air-conditioning) are not sufficient
- Licences must be current at time of application and maintained throughout accreditation
State licence verification: The CEC verifies electrical licence status directly with state licensing bodies. Ensure your licence is current and shows no conditions that would restrict solar PV work before applying.
Required Training
CEC accreditation requires completion of specific competency units from the national training framework. The key units are:
| Unit Code | Title | Why Required |
|---|---|---|
| UEESS00040 | Install Grid-Connected Photovoltaic Systems | Core solar PV installation skills |
| UEESS00038 | Design Grid-Connected Photovoltaic Systems | Required for designer accreditation |
| HLTAID011 | Provide First Aid | Mandatory safety requirement |
Training is available through registered training organisations (RTOs). The CEC maintains a list of approved RTOs on their website. Formats vary — face-to-face workshops, blended online/practical, and full online options are available. Practical assessment components typically require in-person attendance.
Important: Ensure the RTO delivering your training is CEC-approved for the specific units required. Some RTOs are approved for training but not for the CEC recognition pathway — confirm before enrolling.
The CEC Online Exam
After completing training, applicants must pass the CEC’s online open-book assessment. The exam covers:
- AS/NZS 5033:2021 PV array installation standard
- AS 4777.2:2020 grid connection standard
- CEC Guidelines for Accredited Installers
- System design principles (string sizing, inverter matching, DC cable sizing)
- Safety requirements (working at heights, DC electrical hazards, earthing)
The exam is open-book — candidates can refer to the standards and CEC guidelines during the assessment. A passing score is required before the accreditation application can proceed.
Application Process and Costs
Step 1 — Gather documentation:
- Evidence of electrical licence (licence number for online verification)
- Training unit completion certificates from CEC-approved RTO
- First Aid certificate (HLTAID011 or equivalent, current within 3 years)
- Public liability insurance certificate (minimum $5 million coverage, naming CEC as interested party if required by your insurer)
- Professional indemnity insurance certificate
Step 2 — Submit online application:
The application is submitted through the CEC portal. All documents are uploaded digitally. Processing typically takes 2–4 weeks.
Step 3 — Pay fees:
| Fee Type | Approximate Amount (2026) |
|---|---|
| Initial application | $400–500 AUD |
| Training (external RTO) | $800–2,000 AUD (varies by provider) |
| First Aid course | $100–200 AUD |
| Insurance (annual) | $800–2,500 AUD (varies by coverage level and insurer) |
| Total first-year cost | $2,100–5,200 AUD |
Annual Renewal
CEC accreditation expires annually. Renewal requires:
- Annual renewal fee ($300–400 AUD)
- Confirmation of current electrical licence
- Confirmation of current insurance (public liability + professional indemnity)
- Completion of any CEC-mandated CPD for the renewal period
The CEC sends renewal reminders by email. Do not wait for the expiry date — if accreditation lapses, the reinstatement process requires a new application (not a renewal), with associated fees and delays.
Lapsed Accreditation and STCs
If your CEC accreditation lapses, any systems installed during the lapsed period are not eligible for STCs. This is a significant financial and reputational risk — customers who have already received an STC discount on an invoice may need to repay if the CEC determines the installation was ineligible. Maintain accreditation renewal as a non-negotiable business process.
CEC Approved Solar Retailers
In addition to installer accreditation, the CEC operates an Approved Solar Retailer programme for businesses selling solar systems. Approved Retailers commit to a code of conduct covering accurate information, transparent pricing, and responsible sales practices. The Approved Retailer scheme is separate from installer accreditation — a business can hold one, both, or neither.
For residential customers, choosing an Approved Solar Retailer provides additional consumer protection. For installers, many larger businesses hold both installer accreditation and Approved Retailer status.
CEC Battery Installer Accreditation
A separate CEC Battery Installer Accreditation is required to install battery storage systems under AS/NZS 5139:2019. Requirements include:
- Current CEC Solar Installer Accreditation
- Completion of additional training units covering battery storage installation
- Knowledge of AS/NZS 5139:2019 requirements
Battery accreditation is increasingly important as the Australian battery storage market grows. Many state government battery incentive programmes (Victoria Solar Homes, SA Home Battery Scheme) require CEC-accredited battery installers.
Pro Tip: Verify Accreditation on the CEC Register Before Subcontracting
If you subcontract installation work, verify the subcontractor’s CEC accreditation on the public CEC register before they install. An unverified subcontractor with lapsed accreditation puts your STC claims at risk. The CEC register is searchable at cleanenergycouncil.org.au — check both the name and accreditation expiry date. Use solar proposal software that records accreditation numbers in project documentation to create an audit trail.

Frequently Asked Questions
What is CEC accreditation and why is it required?
CEC accreditation from the Clean Energy Council is the credential required for installers of STC-eligible solar systems. Without it, customers cannot claim the STC discount. Most DNSPs also require CEC-accredited installers for grid connection applications.
What is the difference between installer and designer accreditation?
Installer accreditation covers physical installation work. Designer accreditation covers system design and documentation. For small residential installations, most installers hold both. For larger commercial projects, the roles are typically separate.
How much does CEC accreditation cost?
Initial costs total approximately $2,100–5,200 AUD (application fee, training, First Aid, insurance). Annual renewal is approximately $300–400 AUD plus insurance renewal.
Can I lose my CEC accreditation?
Yes — for non-renewal, installation defects, or conduct issues. Maintain renewal as a business priority. Installations during a lapsed accreditation period are not STC-eligible, creating financial liability.
Do I need separate accreditation for battery storage?
Yes. CEC Battery Installer Accreditation is separate from solar installer accreditation and requires additional training units and AS/NZS 5139:2019 knowledge.
