What is a Bloomberg Tier 1 Solar Panel?
Bloomberg’s infamous tier 1 ranking is NOT a measure of Solar Panel quality in any way. It is simply an indication of the bankability of the manufacturer based on publicly released information on the financial health of the company. This should give you an idea if the company is a large, well-known manufacturer.
Canadian Solar was listed as a tier 1 panel in the latest Bloomberg NEF report.

What is PV Evolution Labs Top Performer?
PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panel’s performance.
Canadian Solar Panels was listed as a top performer for 5 performance tests(damp heat, mechanical stress sequence, hail stress sequence, PID, LID+LETID, PAN performance) in the latest report. Please note that Canadian Solar had a large number of different solar panel models tested with varying results.

Why is office location in Australia Important?
Most solar panel manufacturers entering the Australian market first set up their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their 10-year product warranty.
Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing.
Canadian Solar’s Australian head office is located in Cremorne, Melbourne and they have warehouses in Sydney, Brisbane and Perth. For warranty claims you can contact their head office on 03 8609 1844.

Canadian Solar Panels – Points of Difference
There are many solar panels out there, what makes Canadian solar panels stand out?
A wide range of solar panels
Canadian Solar has a wide range of solar panels, it offers a power range from 200W to 665W including Monocrystalline, Polycrystalline, and PERC. Canadian Solar panels can be used in almost every solar project including residential, commercial, and solar farms.
A Trusted and Long History Company
Canadian Solar have a long history in the competitive solar panel market operating for over 20 years. Through-out the majority of this time Canadian Solar has remained on the Bloomberg tier 1 list (measuring financial stability) and is listed as one of the leading manufacturers by production capacity (No.4 in 2022).
Canadian Solar Panel Technologies
A vast range of solar panels listed on Canadian Solar’s Australian website are approved by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program. Canadian Solar have different models directed at the residential, commercial and utility-scale market.
HiHero Series 
The series of HiHero is High-Efficiency Heterojunction (HJT) Cell Module. They have a higher module efficiency (up to 22.5%) and a longer product warranty and performance warranty (25 years and 30 years respectively) The power range is 415W to 440W, it is suitable for both commercial and residential projects.
KuPower Series 
KuPower Series is the series Canadian Solar has offered for many years. They keep a number of panels in stock to act as replacements on older systems where required. Kupower has a wide range of module replacements from 200W to 355W with different sizes for 6-inch, 48/60/72 full-cells, and 5-inch, 72/96 full-cells. They can also be used to replace the other brand of solar modules that have failed, not just Canadian Solar
BiHiKu Series
Mostly applicable in the utility-scale market or large-scale commercial ground-mount projects. These bificial panels enable light to be absorbed from the top and bottom of the panel increasing the energy yield by up to 30%. These panels are up to 665W and up to 2.4m in length, significantly larger in dimensions and output than a typical residential solar panel.
HiKu Series
The HiKu Canadian Solar panels are regularly used in rooftop commercial projects as they offer great module efficiency at a cost-effective price. These panels are typically seen at 330W at their most cost effective price point, but the modules in this series can go up to 670W. The module has been designed for easy and efficient installation on rooftops and is a popular choice among Australian residential and commercial installers.
All Black Series
The all black series creates an aesthetic appeal with a black frame and black back sheet. These panels are designed for residential homes and to provide a sleek look. Despite the dark colour of the panels, Canadian Solar’s modules still perform well in hot conditions with a low temperature coefficient (Pmax) of -0.34 % / °C.
Independent Testing of Canadian Solar Panels by PV Labs Australia
In a 2023 study commissioned by the ACT Government, PV Labs Australia testing a sample of 121 solar panels sourced directly from suppliers in the market. The solar panels featured 14 different solar panel brands and they have published the results.
The solar panels were tested via a visual inspection, STC power, electroluminescence, wet leakage and potential induced degradation.
Canadian Solar had mixed results from the 2 rounds of testing. In the first round of testing they scored a relatively low score of 76 out of 100, however recovered in round 2 with a good score of 92 out of 100.
It was noted in the accelerated aging test that a Canadian Solar panel developed a likely shunt through the testing procedure.
Canadian Solar’s Warranty Policies in Australia
Solar panels come with a product and performance warranty. The product warranty is designed to cover manufacturing faults in the panel that leads to damage or malfunction and is typically 10 years for most solar panel manufacturers. Canadian solar offer either 12 or 15 years a product warranty depending on which module you are looking at, which we would consider to be slightly ahead of the market’s expectations.
The performance warranty on a solar panel covers a minimum level of output of the solar panel based around a normal degradation rate for the panel. Most solar panels guarantee a maximum degradation rate of 2.5% in the first year and 0.7% a year thereafter until the 25th year leaving a remaining output of ~80% of its nameplate value. Canadian Solar’s warranty again varies by panel but is often slightly ahead of this standard. For example the commonly used HiKu series comes with a maximum degradation guarantee of 2% in the first year and 0.6% from year 2 to year 25 leaving a end value of 84.8% of the labelled power output.
Canadian Solar have Australian offices and we anticipate this to be one of the easier companies to claim warranty from even if your installer is no longer around. Canadian Solar have a different warranty policy and document for each solar panel series so make sure you look up the right document on their website that corresponds with your quote to see what you are being offered.

Canadian Solar Panels Pros and Cons
Pros
- Tier 1 Solar Company by Bloomberg New Energy
- Have an Australian Head-Quarters in Melbourne along with Warehouses in Sydney, Brisbane and Perth
- Premium panels have 25 year performance and product warranty
Cons
- Name can be confusing for customers who think the panels will be manufactured in Canada. The majority of panels that land in Australia are Chinese manufactured. Whilst Canadian Solar do still operate manufacturing plants in Canada, these panels are typically deployed to other Countries.
Should I Buy Canadian Solar Panels?
Canadian Solar have been around for a long time and suit customers looking for a mid-range panel that has been tried and tested. With a presence in Australia, all signs point to their warranty policy and process not causing too much trouble if you have to go down that path. We would recommend choosing one of the Canadian Solar panels that now offer a 25-year product warranty for extra piece of mind.
Example of a Canadian Solar Commercial Solar Project
In 2016 Canadian Solar installed a photovoltaic system on the roof of the International Convention Centre Sydney (ICC Sydney) located in Darling Harbour. Which when installed was one of Australia’s largest panel arrays in a business district. Canadian Solar in conjunction with CSA Services constructed the solar system across the three sites, this installation featured state-of-the-art products and an innovative roof-top mounting structure. The system consists of 2,004 260W Canadian Solar modules and is estimated to generate around 545MWh of electricity annually.

Reviews from Australians who have installed Canadian Solar Panels
Canadian is a great solar panel brand with long warranties in case anything goes wrong.
I chose Canadian Solar Panels for their salt resistance since we are the shore of a saltwater lake. Black panels look good on the roof and so far I am happy with the performance. Looking for the first full period bill.
would be happy if they turned up to install them
System is performing as advertised. No problems at this stage (touch wood).
Works as expected
System performance is sound after 6 years
Performance is great so far
Output ia great and a good quality
Very happy overall with panels and their installation.
Have worked efficiently continuously with little deterioration in performance
SEEMS TO BE DOING WHAT IS REQUIRED BUT ONLY A COUPLE OF MONTHS OLD.
It's been just over 4 yrs with the Canadian solar panels no issues at all very happy.
Nice and shiny panels
Canadian solar panels
I cannot comment as they were only installed and ooerating for 2 weeks now
I am very happy with the style of the Canadian panel that was recommended by Solar Wholesalers. I live on the coast and experience high winds, and the extra stiffening brace in the middle of the panels is a bonus.
At this early stage they appear very efficient.
Was upgraded to these panels from time of quote to install
Work terrific
Recommended by sunfloe
Can't fault them, they are doing the job.
They seem ok. Having an issue with State 567. Trying to sort out with electrical company.
No issues
Looks great
nil comment
I guess all panels in this range are similar. Too early to tell. I choose these ones mostly for the convenient power output (actually, slightly less than most others), which made an even number of panels in my case (18, instead of 17 with other similar brands). Also, they have black bezel, which looks better than silver.
They work. Around 73 percent efficiency. Max 3.6kW from a 4.9kW system
Happy with the performance of the panels so far!
Efficient panels, they do not lose output on really hot days
The black panels look so great, they blend in so well. Much less noticeable than other panels I've seen.
Everything is going well to date.
product seems good
Am happy with what has been installed
None
N/A
Installed in 2018 by another company and have operated satisfactorily since
Excellent so far
too soon to compare estimates given to me prior to signing the contract however my app tells me during the first 3 days of power generation this 6.6 (6.03) system recorded 40kw on a clear hot day in January ( 36 degrees ). These panels are facing south on 27 degree and 22 degree metal roofs. We noticed a distinct drop in radiant heat from the ceilings of our two story house . ( panels can cool the roof up to 5 degrees in summer).
No issues look great
Appears to be working well, even on overcast days.
One of the best in the market
Solid product, adaptable to shading and low light, so far good output above expectations despite poor weather
Chosen for better warranty-25yrs. Also used by well known commercial entities.
Excellent
best choice
Very good
This is my second installation using Canadian Solar panels. The electricity generation is in line with expectation.
