You’ve probably seen the words ‘Tier 1 solar panels‘ plastered all over solar ads and installer websites. But what does it actually mean? And more importantly, does it protect you from buying a dud system? In Australia, understanding Tier 1 solar panels is one of the most important things you can do before signing on the dotted line. The answer might surprise you.
What does ‘Tier 1 solar panel’ actually mean?
The term ‘Tier 1’ doesn’t come from a government body, a testing lab, or a safety regulator. It actually comes from Bloomberg New Energy Finance (BNEF), a financial research firm. They created the tiering system to rate manufacturers based on financial stability rather than panel quality.
To be listed as a Tier 1 manufacturer, a solar company must have supplied panels to six or more projects that were financed by banks on a non-recourse basis in the last two years. That’s it. No performance test. No quality check. No efficiency rating.
So when an installer tells you their panels are ‘Tier 1’, they’re really telling you: this manufacturer has been around long enough to attract bank-backed financing. That’s useful information, but it’s not the whole picture.

Why the ‘Tier 1 solar panels’ label can still mislead you
Plenty of Australians are caught off guard when they discover this. They assumed ‘Tier 1’ meant ‘the best quality available’. In reality, it’s a financial metric, not a performance guarantee. Here’s what Tier 1 does NOT mean:
- The panels are the most efficient on the market
- The panels passed independent quality testing
- The manufacturer offers the best warranty terms
- Your installer is using the latest model from that brand
- The panels are right for your Australian climate and roof type
A Tier 1 manufacturer can still produce lower-performing product lines or sell older stock. Always ask which specific panel model you’re being quoted, not just the brand name. Check our page for our recommended Tier 1 solar panel products.
Tier 1 solar panels in Australia: What the Bloomberg list actually tells you
Bloomberg BNEF publishes and updates the Tier 1 solar manufacturer list quarterly. You can check the current list at BloombergNEF.
Being on the Bloomberg Tier 1 list is a positive sign. It shows the manufacturer is financially stable enough to back long-term warranty commitments. But in Australia, there’s a better local guide to follow.
The Clean Energy Council (CEC) approved the product list
The Clean Energy Council (CEC) maintains an Approved Products List specifically for the Australian market. Only panels on this list can be used in solar systems eligible for government rebates under Australia’s Small-scale Renewable Energy Scheme (SRES). This is the list that actually matters for Australian homeowners.
If a panel isn’t on the CEC-approved list, your system won’t be eligible for STCs (Small-scale Technology Certificates), which means you lose thousands of dollars in rebates. Always cross-check your solar installer’s quote against this list.
Tier 1 solar panel comparison: Key facts at a glance
| Factor | Tier 1 Solar Panels | Non-Tier 1 Panels |
| Bankability | Financially stable manufacturers | Often, small or unproven companies |
| Manufacturing volume | 500 MW+ per year | Below 500 MW per year |
| Warranty support | Typically, a 10–to 25–year product warranty | Shorter or unreliable warranties |
| Performance guarantee | Linear degradation guarantee (80%+ at 25 yrs) | Vague or no degradation data |
| CEC approval (Australia) | Most are CEC-approved | May not appear on CEC list |
| Resale & Finance value | Accepted by banks & valuers | May affect property value or finance |
| Examples (2026) | Jinko, LONGi, Canadian Solar, REC, Qcells | Unknown offshore brands |

How scammers abuse the ‘Tier 1 Solar Panels’ label in Australia
This is where it gets important. Some solar companies use ‘Tier 1’ as a blank cheque marketing term — slapping it on panels that have never been independently rated, sourced from obscure offshore factories, or that were briefly listed and then removed.
Common red flags to watch for:
- The installer cannot name the specific brand and model of the panel being installed
- The quote says ‘Tier 1 panels’ but doesn’t list the manufacturer or CEC code
- The price is unusually low — quality panels have real manufacturing costs
- Warranty is backed only by the installer, not the manufacturer directly
- The company is newly registered and has no visible track record
The Australian Competition and Consumer Commission (ACCC) has previously taken action against misleading solar marketing claims. You can check your consumer rights on the ACCC website.
Frequently Asked Questions About Tier 1 Solar Panels in Australia
Is Tier 1 the same as the best quality?
No. Tier 1 is a financial classification from Bloomberg BNEF, not a quality or performance rating. It tells you the manufacturer is financially stable, which is helpful, but it doesn’t guarantee the panels are the most efficient or reliable.
Do I need Tier 1 panels to get the government solar rebate?
Not specifically. To claim federal STCs, your panels need to be on the CEC Approved Products List, and your installer must be SAA-accredited. Many Tier 1 panels meet this standard, but always confirm with your installer.
Can I check if panels are on the CEC-approved list myself?
Yes. The CEC maintains a publicly searchable list at cleanenergycouncil.org.au. Search by brand and model before agreeing to any quote.
What is a good efficiency rating for solar panels in Australia
For most homes, look for panels with efficiency between 19% and 22%. Higher efficiency helps if you have limited roof space. Panels above 22% are considered premium and tend to cost more.
How many quotes should I get before buying solar panels?
We recommend at least three solar quotes from different installers. This helps you fairly compare panel brands, system sizes, warranties, and prices. Energy Matters can connect you with SAA-accredited installers across Australia.
The bottom line on Tier 1 solar panels in Australia
‘Tier 1 solar panels’ sounds impressive, but it’s really just a financial benchmark. In Australia, what matters more is whether your panels are on the CEC-approved list, whether your installer is SAA-accredited, and whether the warranty terms actually protect your investment for 25 years or more. Don’t let clever marketing language distract you from the details. Get informed, ask the right questions, and choose a trusted installer who puts your needs first.
Energy Matters has connected Australians with quality solar since 2005. We work with SAA-accredited installers and only recommend panels we’d put on our own roofs.
