Australian office?

Yes. Canadian solar panels have set up four warehouses and representative offices in Australia. Their head office is located in Cremorne, Melbourne, while the other warehouses are in Perth, Sydney, and Brisbane. 

Why an Australian office is important

Being one of the largest mass-solar panel manufacturers globally, warranty claims are bound to occur frequently among the company’s customers.

Having an office in Australia makes it easier for customers to contact the company’s representatives for help. It also eases the burden of relying on solar installers who may disappear from the market at any time.


Are Canadian solar panels perfect for rooftop solar?

It depends. While Canadian solar panels are very cheap, their efficiency is significantly lower compared to 22.6% of the world leaders like SunPower and LG.

This means that you’ll need many solar panels to get the most of your solar systems. It’s ideal for homeowners with a large roof space and a tight budget.
