What is CEC Accreditation?
The Clean Energy Council (CEC) is Australian's peak body for the clean energy industry. CEC accreditation is the standard qualification for solar installers in Australia, and choosing a CEC-accredited installer is essential for receiving government rebates through Small-scale Technology Certificates (STCs).
Unlike some certifications that are voluntary, CEC accreditation is effectively mandatory for residential solar installations in Australia — without a CEC-accredited installer, you cannot claim STCs, which typically reduce your system cost by $2,000-$4,000.
Why CEC Accreditation Matters
STC Rebate Eligibility
Only CEC-accredited installers can create STCs for your system. These certificates are worth $2,000-$4,000 as an upfront discount on a typical residential system.
Quality Assurance
CEC-accredited installers have completed approved training and hold valid electrical licenses. They must comply with Australian Standards for solar installation.
Feed-in Tariff Access
State feed-in tariffs require systems installed by CEC-accredited professionals. This provides ongoing income from surplus electricity exported to the grid.
Accountability
CEC can investigate complaints and suspend or revoke accreditation for non-compliance, giving consumers an additional layer of protection.
Types of CEC Accreditation
CEC Accredited Installer
The primary accreditation for solar installers. Required for customers to receive Small-scale Technology Certificates (STCs) which provide an upfront discount on system cost. Must hold a valid electrical license and complete CEC-approved training.
CEC Accredited Designer
For professionals who design solar PV systems but don't necessarily install them. Covers system sizing, component selection, and compliance with Australian Standards.
CEC Approved Solar Retailer
A voluntary code of conduct for solar retailers. Approved retailers commit to higher standards of sales practices, warranties, and after-sales support. Look for the CEC Approved Retailer logo.
How to Verify CEC Accreditation
Verify any installer's CEC accreditation through the official Clean Energy Council directory:
- Visit the CEC “Find an Installer” page at cleanenergycouncil.org.au
- Search by name, company, or postcode
- Check the accreditation type and that it's current
- For retailers, also check the CEC Approved Solar Retailer list for extra consumer protection
Important: Some companies employ subcontractors. Ensure the person who physically installs your system (not just the company) holds current CEC accreditation.
STC Rebates Explained
Small-scale Technology Certificates (STCs) are the primary government incentive for residential solar in Australia. The number of STCs you receive depends on your system size, location (solar zone), and the years remaining until 2031 when the scheme reduces.
Typical STC Values (2026)
5kW System
~$2,200
6.6kW System
~$2,900
10kW System
~$4,400
Values are approximate and depend on STC spot price and solar zone.
Most installers offer a “point of sale” discount where they assign your STCs to a registered agent and reduce your system price upfront. This is the simplest approach for most homeowners.
