Finn's Canadian Solar Inc Panels Review & Verdict

Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO

Canadian Solar Panels are not made in Canada. But they are very good budget panels from a massive Chinese company that do what they say on the tin. They are well supported and well warranted in Australia. I'd be happy to have them on my roof.

There's not much more to say. A sensible choice that should sit on your roof for decades churning out the kilowatt-hours and pay for themselves quicker than a more expensive brand. Sometimes the boring but sensible choice is the right choice. 

Canadian Solar Inc Panels: Pros & Cons

  • Well-built, consistent dimensions.
  • Variety of models offering competitive efficiency ratings.
  • Large, vertically integrated Tier 1 company making all solar components in house.
  • Shipping gigawatts of solar panels.
  • Most heavily involved in using their own panels on their own solar farms.
  • Local office to handle warranty even if your retailer/installer has disappeared.
  • They're not Canadian at all.
  • Few models are offered in an install-friendly width, most are 1130mm or 1300mm wide, making them difficult to handle and easy to damage.

About Canadian Solar Inc

Canadian Solar is a "Tier 1" producer of panels. Despite their name, any panels you buy in Australia will not be made in Canada. Canadian Solar panels we purchase are most likely to be made in China - not that there's anything wrong with that.

These days the company's panels generally carry a 25 year product warranty in Australia. Canadian Solar has an Australian office located in Melbourne to look after local support and warranty issues.

Canadian Solar produces a variety of panels, all of which are corrosion resistant and therefore suitable for installation anywhere in Australia. The company manufactures poly and monocrystalline modules, most using PERC (Passivated Emitter and Rear Contact) technology; but some boasting TOPCon (tunnel oxide passivated contact) or HJT (heterojunction) tech. Like many major manufacturers, it has also moved into half-cut (dual) and shingle cell configurations.

The highest efficiency panels produced by Canadian Solar (HiHero) are up to 22.5% efficient. This higher than average efficiency can be useful when available roof space is limited.

You can find specifications and pricing of selected models available in Australia on my solar panel comparison table.

Company History

In 1987 the founder of Canadian Solar, Shawn Qu, was earning around $5 a week in today's money teaching in China. That year he moved to Canada and began studying to obtain his masters degree in physics. In 2001 he founded the company.

Shawn Qu now spends most of his time in China and that is understandable, as in winter it is so cold in Canada it is possible to freeze to death in less time than it takes for a bear to find you and eat you.

It hasn't always been smooth sailing for the company. The firm experienced a significant setback in June 2016 when a cell manufacturing plant they owned in Funing was hit by the worst tornado in China in 50 years, injuring employees and collapsing almost 4 hectares of factory buildings.

Manufacturing Locations And Capacity

Canadian Solar has 20 manufacturing facilities spread across Asia and the Americas. Its 2022 module production capacity was approximately 32 GW, while cell manufacturing capacity was around 19.8 GW.

As August 2023, the company had shipped around 96GW of panel capacity - quite a jump on September 2022's  75 gigawatts and from its mid-2021 tally of 55 gigawatts.

Canadian Solar Builds Solar Farms

Canadian Solar is more heavily involved in the construction of solar farms than most solar panel manufacturers. The company says it has developed, built and connected more than 8.8GW of projects across 20 countries - including large scale PV power stations here in Australia.

By August 2023, the Company had approximately 609 MW of its own projects in operation, 6.9 GW of projects under construction or in backlog, plus an additional 17.7 GW of projects in advanced and early-stage pipeline. 

Warranty Procedure For Orphaned Canadian Solar Customers

If you have purchased Canadian Solar panels from a solar installer who has since gone out of business, the responsibility for warranty claims shifts to Canadian Solar. Their customer service line in Australia is 03 8609 1844 - affected customers should contact this line for assistance and advice on how to arrange for panel replacement under warranty. 

I Am Fine With Recommending Canadian Solar Panels

Canadian Solar is considered a tier 1 solar panel producer, which means banks and other institutions consider both the panels and the company reliable enough to be a worthwhile investment.

The company's panels are pretty popular with installers here in Australia, ranking equal third in the SolarQuotes 2022 Installers Choice awards; in the budget category.

I have no problem recommending Canadian Solar panels. They are a generally reliable panel that provides good value for money. Just don’t expect them to come from Canada.

Had 10 kW Canadian Solar panels installed almost 7 years ago with 2 x SMA SunnyBoy inverters. Both components of this solar array seem to be pretty much bullet proof.
The system is producing around 13,000 kW per year, down from 14,000 kW per year initially.
Very happy with this system. It paid for itself in approx 3 years.
We had not received a power bill until just recently, following the recent increases in power prices, and we are now planning to add batteries.

An incentive was offered by Go Green Energy for this review. Learn more here.

We have't paid a power bill as yet, and it appears that this won't happen. At the moment we are using an air conditioner and clothes drier most every day and the solar panels account for this usage.

The only time I contacted Go Green was to get his recommendation for a solar panel cleaner.

Our 8kW of panels are split over the east and west faces of our roof. (The north face is too small for the array size we have.) The east bank get us off grid in the morning very early in the sun's travel, and the west-facing panels keep us off grid until just before sunset for almost all our electrical loading.

In the middle of the day, neither set of panels is generating full power, but because the total array power exceeds the (6kW) inverter capacity, the inverter is running at full power for a major part of the day, which would not happen if the panels were all concentrated on one side of the roof.

However, it has only been 3 weeks since my system was installed. Time will tell.

I'd like to think these panels weren't made in China but then they probably were. My research reveals they are supposed to be a reasonably good quality, good performing panel but I guess time will tell.

Update: I am disappointed in the performance of these panels as they are not generating the amount of electricity I thought they would. I'm not sure if there is a problem with them or if it's just because of inclement weather but I am still getting electricity bills that are not that much improved on what I used to get pre-installation of this system.

The panels are the latest 365Kw models, slightly larger than the 300's apparently but well made with additional reinforcing with black surrounds. They face WNW but start generating power at 8.00 am in the morning (winter) before they even have direct sunlight on them.

Over summer I ended up producing up to 40Kw daily, so exporting up to 30 Kw at times so very happy. Over the last Qtr I got a $65 Credit from Red Energy with a FiT of 11c pkw.
