With solar power gaining huge demand in Australia amidst rising electricity costs, most homeowners are looking for the cheapest solar installers to install solar systems on their roofs.
Unfortunately, what most don’t realise is that these cheap quotes often come from unaccredited installers and end up costing them more later.
Before you hire a solar installer in Australia, read this post to understand why you should avoid cheap, unaccredited installers and work only with CEC-approved solar installers.
What Are CEC-Accredited Solar Installers?
A CEC accredited solar installer is approved by the Clean Energy Council to design and install solar systems that meet strict Australian standards.
This isn’t just a badge. It confirms the installer has the training and qualification to safely install grid-connected solar systems under Australian electrical standards.
A properly CEC accredited solar installer in Australia ensures:
- Full compliance with AS/NZS 3000 electrical standards
- Safe and tested grid-connected installation
- Eligibility for STC rebates
- Valid manufacturer warranties on panels and inverters
- Proper system commissioning and documentation
In short, accreditation protects both your system and your investment.
What Is a Non-Accredited Solar Installer?
A non accredited solar installer in Australia (often found in “cheap solar deals”) is an installer who does not hold Clean Energy Council accreditation or may not follow full compliance standards.
These operators may still offer solar installations at lower prices, but the risks come from what is often missing:
- No recognised CEC accreditation
- Inconsistent or missing electrical licensing
- Poor documentation and compliance paperwork
- Limited accountability after installation
This is where “cheap solar” can quickly become expensive solar.
Why You Should Always Hire a CEC Accredited Solar Installer
Choosing a CEC accredited solar installer in Australia isn’t just about quality — it’s about protection.
A compliant installer ensures:
- You receive your full solar rebate (STC rebate Australia worth $2,000–$5,000 )
- Your home insurance remains valid
- Your system meets all AS/NZS 3000 standards from day one
- You get at least a 5-year labour warranty as required by law
- Your system passes grid approval without issues
- You get local support all the times
- Your wiring is code-compliant
Why You Should Avoid Non-Accredited Solar Installers
The risks of choosing a cheap solar installer in Australia often don’t appear immediately — they show up months or years later.
Common issues include:
- Loss of STC rebate eligibility – Up to $2,000–$5,000 lost
- Insurance claims are being denied on non-compliant systems
- No labour warranty support
- Unsafe DC wiring and installation faults
- Failed grid inspections or disconnection risks
- No accountability if the installer disappears
One of the biggest hidden risks is electrical safety. Poor installation practices are a known contributor to rooftop solar fire risks in Australia, especially when DC isolators and cabling are not installed correctly.
Here is a comparison table summarizing the differences between hiring a Clean Energy Council (CEC) accredited installer and a non-accredited installer.
CEC Acreditted Solar Installers Vs Non-Acreditted Installers Summary
| Feature / Risk | CEC Accredited Solar Installer | Non-Accredited Installer |
| Government Rebates | Guarantees your full STC rebate (saving you $2,000 to $5,000). | You lose eligibility. You will have to pay the full price yourself. |
| Home Insurance | Keeps your coverage valid by meeting official safety standards. | Insurance claims can be denied if a fire or fault happens. |
| Workmanship Warranty | Includes a mandatory 5-year labour warranty by law. | No local support or warranty if things go wrong. |
| Electrical Safety | Follows strict AS/NZS 3000 standards to prevent fire risks. | High risk of unsafe DC wiring and faulty rooftop installations. |
| Grid Connection | System passes grid approval smoothly from day one. | Insurance claims can be denied if a fire or fault occurs. |
| Accountability | Provides reliable local support and code-compliant wiring. | No real accountability if the company disappears later. |
How to Know if Your Solar Installer Is CEC Approved
Before signing any contract, always verify:
Ask for their CEC Accreditation Number: A legitimate installer will provide it immediately. You can verify it on the Clean Energy Council register.
Check Electrical Licensing: A licensed solar electrician in NSW (or your state) is legally required for grid-connected installations.
Confirm Warranty Terms: A reputable installer should clearly outline workmanship warranty coverage — not vague promises.
Watch for Red Flags: Be cautious of:
- Extremely low quotes with pressure sales tactics
- Cash-only deals
- No compliance paperwork
- No clear installation process
Are Cheap Solar Installers Worth It? Real Cost of Going Cheap
On paper, cheaper solar quotes can look attractive. In reality, the savings are often temporary.
We’ve seen homeowners lose:
- $2,000–$5,000 in STC rebates
- Thousands in rectification costs
- Warranty protection on major components
- 100% Insurance coverage on non-compliant systems
Fixing a poorly installed system can cost $3,000–$8,000 or more, depending on the severity of the issues.
In many cases, homeowners end up paying twice — once for the installation, and again for the correction.
What a Proper CEC Accredited Solar Installation Includes
A professional licensed solar installer in Australia delivers far more than panels on a roof.
A compliant installation includes:
- Certified system design and planning
- Safe electrical installation to all AS/NZS 3000 standards
- Correct DC and AC wiring practices
- Grid connection approval and documentation
- Full STC rebate processing
- Manufacturer and labour warranty protection
- Ongoing local support after installation
This is where long-term value actually comes from.
Final Verdict: Cheap Solar vs CEC Accredited Solar Installers
Solar is one of the best long-term investments for Australian homeowners — but only when it is installed correctly.
A CEC accredited solar installer in Australia protects your rebates, your insurance, your warranties, and most importantly, your home’s safety.
A cheap, non-accredited installer may reduce upfront costs, but often introduces long-term financial and safety risks that outweigh the initial savings.
At E-Green Electrical, every system is installed by fully licensed, insured, and CEC accredited solar installers in NSW, ensuring every job is compliant, safe, and built for long-term performance.
Because in solar, the real cost is never just the installation — it’s what happens after.
