Canadian solar panel review

Canadian Solar panels sold and installed by Solar4Ever

Canadian Solar 275W - 60 polycrystalline cells. 1650mm x 992mm x 35mm

Voltage 31V x Current 8.88A = 275W

Price $250 ($0.91 per watt)
Power loss on 30°C day = 0.41 x 25 = 10%

Power loss on 40°C day = 0.41 x 35 = 14.35%

Canadian Solar 330W - 72 polycrystalline cells. 1960mm x 992mm x 35mm

Voltage 36.8V x Current 8.69A = 320W

Price $275 ($0.83 per watt)
Power loss on 30°C day = 0.41 x 25 = 10%

Power loss on 40°C day = 0.41 x 35 = 14.35%

About Canadian solar panels

Company founded in Canada and still has headquarters there but in truth this is really a fully Chinese operation. Canadian Solar are one of the biggest and best known brands and make a very good mainstream product at a reasonably competitive price. The longer 72 cell 330W panel (31 cm longer than a regular 60 cell panel) isn't any more efficienct than a regular panel but on some roofs it does allow us to fit more panel power with fewer panels and therefore lower installation costs.

Are Canadian Solar any better than Jinko, Trina, Eging, Talesun, Amerisolar, GCL and all the other mainstream brands? No. They are exactly the same, but people prefer to buy brands they have heard of. Whether people think that they are buying a panel made in Canada is probably another factor too, but they are as Canadian made as Amerisolar are American made. Actually, 8% of Amerisolar panels ARE made in California, which is a much higher percentage than Canadian Solar's North American output.

Technology
Technology buzz words is a particular favourite of Canadian Solar marketing. Whether it's more busbars or PERC or any of the miriad of fancy technologies most of the manufacturers trumpet, remember it's all about increasing cell output per square metre of roof space.

For example, on an unshaded 25 degree tilt, North facing roof in Perth, 6.6kW of solar panels running to a 5kVA inverter will make 11,570kWh or 31.69kWh per day. In Sydney it will make 9,960kWh or 27kWh per day, Melbourne 9,800, Brisbane 10,780 etc.

The point is that ANY solar panel, any make, any model, economy or premium, when you have 6.6kW of them will make those outputs. What you pay for is roof space efficiency. You'll need 25 x 265W panels or 24 x 275W panels or 22 x 300W panels, or 18 x 360W panels to achieve 6.6kW and that's what you are paying for. The more power that can be packed into the same size 1.6M x 1M solar panel frame, the less panels you need to make the same power. From an install cost viewpoint, installing 3 fewer panels might save you $300, but if you have paid $1000 more for the panels to do it, it's pointless. High efficiency panels are only for people who have limited roof space.

 

What's not good about Canadian Solar?

Very little.


Their defect warranty is 10 years, whereas Amerisolar, Q.Cells and others give 12 years

The most interesting fact about Canadian Solar is that a poorly paid Canadian based science teacher managed to first start a solar panel company in 2001, and by 2016 had turned it into one of the top 3 manufacturers, by volume, in the World. Remarkable.
