Check your rebate eligibility
If you've spent any time looking at solar quotes, you've almost certainly seen the letters “CEC” thrown around. CEC approved panels. CEC approved inverters. CEC accredited installer. It's on every quote, every product spec sheet, every installer's website.
But what does it actually mean? And more importantly, what happens if you end up with products or an installer that aren't CEC approved?
The short answer: you lose your federal solar rebate. That's roughly $2,000 to $3,000 off a standard system, gone. So it's worth understanding who the Clean Energy Council is and what their stamp of approval actually guarantees.
What is the Clean Energy Council?
The Clean Energy Council (CEC) is the peak industry body for clean energy in Australia. Think of it like the Master Builders Association, but for solar, wind, batteries and hydrogen. It represents over 700 member companies, from your local rooftop installer all the way up to the big project developers building wind farms.
Founded in 2007 and based in Melbourne, the CEC does a few things that directly affect homeowners:
Maintains the approved products list
Every solar panel, inverter and battery that can be installed under the government rebate scheme must be on the CEC approved list. No listing, no rebate.
Sets installer standards
Until 2024, the CEC directly accredited solar installers and designers. That function has now moved to Solar Accreditation Australia (SAA), but the CEC still provides ongoing professional development training.
Publishes industry data
The annual Clean Energy Australia Report is the most comprehensive snapshot of the sector. The 2025 report found $12.7 billion in new clean energy investment and over 4 million rooftop solar installations across the country.
Advocates for policy
The CEC works with federal and state governments on energy policy, grid infrastructure, and renewable energy targets.
One thing that trips people up: the Clean Energy Council is not a government body. It's an independent industry organisation. The government regulator is the Clean Energy Regulator (CER), which administers the solar rebate scheme and the Renewable Energy Target. Different organisations, similar names. Easy to confuse.

What “CEC approved” actually means for products
The CEC maintains three separate approved products lists: one for solar panels (PV modules), one for inverters, and one for batteries. These aren't just rubberstamp lists. Products must undergo independent lab testing to verify they meet Australian and international safety and performance standards before they're added.
As of 2026, the lists include over 1,800 inverter models and over 1,000 battery models. The panel list is even larger.
Here's why this matters to you: under the Small-scale Renewable Energy Scheme (SRES), your system only qualifies for Small-scale Technology Certificates (STCs) if every component is on the CEC approved list. That's your panels, your inverter, and (if you're adding one) your battery. One non-approved component and the entire system loses its rebate eligibility.
What the CEC checks for each product type
Solar panels (CEC approved modules)
Must meet IEC 61215 (performance) and IEC 61730 (safety) standards. Lab testing verifies power output claims, durability under Australian conditions, and electrical safety. If you're comparing panels, our best solar panels guide only includes CEC approved models.
Inverters (CEC approved inverters)
Must comply with AS/NZS 4777.2 (grid connection) and other relevant standards. This covers everything from power quality and anti-islanding protection to voltage and frequency response. Our inverter comparison breaks down what to look for beyond just the CEC tick.
Batteries (CEC approved batteries)
Must meet industry best practice requirements for safety and performance. This is particularly important since the Cheaper Home Batteries Program launched in July 2025. Only CEC approved batteries qualify for battery STCs. Check our battery comparison for the current standouts.
The practical takeaway: when you get a solar quote, check that the panels and inverter listed are on the CEC approved list. Any reputable installer will only use approved products, but it's worth verifying, especially if you're comparing a quote that seems unusually cheap. That discount might be coming from non-approved components, which means no rebate.
CEC accreditation for installers (now SAA)
For years, “CEC accredited installer” was the gold standard phrase every solar company put on their website. It meant the electrician doing your install had completed the Clean Energy Council's training, passed their assessments, and maintained annual professional development requirements.
In February 2024, that changed. The Clean Energy Regulator appointed Solar Accreditation Australia (SAA) as the new accreditation body, replacing the CEC in this role. All installers had until May 2024 to transfer their accreditation across. If you're getting quotes now, the accreditation you should be looking for is SAA, not CEC. We covered this transition in detail in our SAA accreditation guide.
The CEC still plays a role though. They provide continuing professional development (CPD) courses that accredited installers need to complete. Installers must earn 100 CPD points annually to maintain their accreditation.
Why does accreditation matter? Same reason as the products list. Only systems installed by an accredited installer qualify for STCs. No accreditation, no rebate. It also means the installer has demonstrated competency in system design, electrical safety, and compliance with Australian Standards. That matters when there's 10kW of panels bolted to your roof connected to the grid.
How to check: Ask your installer for their SAA accreditation number before signing anything. You can verify it through the SAA database online. If they can only show you a CEC number and haven't transitioned, that's a red flag. Our guide to vetting solar installers covers what else to look for.

Clean Energy Council vs Clean Energy Regulator
This is genuinely one of the most confusing things in Australian solar. Two organisations with almost identical names doing related but completely different jobs. Here's the distinction:
Clean Energy Council (CEC)
- Independent industry body
- Represents 700+ member companies
- Maintains approved products lists
- Provides installer training/CPD
- Publishes Clean Energy Australia Report
- Based in Melbourne
Clean Energy Regulator (CER)
- Government statutory authority
- Administers the Renewable Energy Target
- Manages the STC/LGC certificate system
- Runs the REC Registry
- Enforces compliance by energy retailers
- Based in Canberra
In simple terms: the CEC sets the product and training standards, and the CER enforces the rebate scheme using those standards. They work together but they're separate organisations. When someone says “the government approves solar panels,” they're half right. The CEC (industry body) tests and approves the products. The CER (government) requires those approved products as a condition for receiving the rebate.
Why this matters when you're getting solar quotes
The CEC approved list is effectively the gatekeeper for your solar rebate. In 2026, a standard 6.6kW system qualifies for roughly $2,000 to $2,500 in STC rebates depending on your postcode zone. That discount only applies if:
Every panel is on the CEC approved modules list
The inverter is on the CEC approved inverters list
Any battery is on the CEC approved batteries list
The installer holds current SAA accreditation
STCs are created within 12 months of installation
The STC rebate is shrinking every year as the scheme counts down to its end in December 2030. That makes it even more important to make sure you're not leaving money on the table by accidentally using non-approved components or an unaccredited installer.
The good news: any installer worth their salt already knows this and will only use approved products. But if you're comparing solar quotes and one seems significantly cheaper than the others, it's worth asking why. Sometimes the answer is efficiency. Sometimes the answer is they're cutting corners on product quality. Checking the CEC approved list takes two minutes and could save you thousands.
