Canadian Solar Panels Expert Review

Canadian Solar Introduction

Over the last decade, the solar market has seen rapid growth and provided around 2.8% of the world’s electricity demand last year. The growth is spurred on by the fall in production costs, and the ability to deploy panels individually or in large installations. In the previous ten years, the price of  PV systems has fallen by nearly 75% and has driven Australia to have one of the highest solar capacities in the world. However, not all solar panels are made equal, and we want to take a look at those provided by Canadian Solar.

Canadian Solar is one of the companies at the forefront of the industry in Australia. We have taken a look at Canadian Solar panels and included a Canadian Solar review. We have also included their impact in the Australian market and whether Canadian Solar panels or other manufacturers like LG Solar are the best choices for your solar installation.

Who is Canadian Solar?

Canadian Solar is an Ontario based solar solutions company. They employee around 13,000 people around the world and are a leading manufacturer of solar panels. With a presence in global markets such as the U.S., Australia, EMEA, East Asia, and more, Canadian Solar panels can be spotted all over the globe.

Like many of its competitors, Canadian Solar panels that sold in Australia are made in China, however, the way they structure their facilities means they control the production process from start to finish. Unlike some of their competitors, this means they do not outsource anything. Canadian Solar aims to deliver clean, safe, and affordable energy around the world.

Canadian Solar Panels

In our review of Canadian Solar panels, we have focused on a few key areas, the efficiency of the panels, performance, cost, and warranty services provided by Canadian Solar. 

Canadian Solar Warranty

Canadian Solar panels are relatively robust, and their entire range is suitable for unfavourable weather conditions including in a coastal environment. They are also rated to withstand brutal winds and the warm temperatures that are common in Australia.

When purchasing panels from Canadian Solar, you will be given a 10-year product warranty, which is the industry standard. Alongside this, they also provide a 25-year performance warranty for panels that fall below an 80.2% power output.

As a comparison, top of the range panels such as the NeON 2 from LG comes with a 25-year product warranty and a 25-year performance warranty for panels that fall below 90.08% after 25 years.

Canadian Solar Panel Efficiency

The efficiency rating of solar panels is determined by calculating the energy output compared to the input from the sun. Once installed, several factors such as temperature and the orientation of the panel in relation to the sun will affect the overall efficiency of a panel.

Canadian Solar makes a range of panels including highly efficient modules, however, the vast majority of panels sold in Australia are in line with the market average. Typically this range has an efficiency rate of around 16%-17%, which is less than high-efficiency panels at the top end of the market that has an efficiency of around 21%. If you have a lot of room on your roof, the lack of efficiency that the Canadian Solar panels provide can be offset by including more panels in your setup, and this is a common thing to do.


Like other panels, those manufactured by Candian Solar perform best when temperatures are around 25-celsius mark. Performance tends to degrade when temperatures increase past this, and this is measured using a temperature coefficient.

Canadian Solar panels have a temperature coefficient of -0.41%/°C, which means that for every degree increase over the 25C, the performance degrades by 0.41%. So for a 35-degree day, you would see a performance decrease of 4.1%.


Canadian Solar panels are considered a good value option for households in Australia alongside the other main companies manufacturing mid-range panels in Asia including Trina, Jinko, Yingli and Q Cells.

Alternatives to Candian solar panels in Australia

Solaray only selects preferred suppliers that meet our strict standards, which is why we normally offer 2 or 3 options at the most, and will never offer you a panel from the cheaper end of the market. The supplier must:

  • Manufacture their own products in their own factories
  • Have a local office in Australia to provide warranty and other support
  • Conduct Research and Development and show a level of technology leadership
  • Have been manufacturing and supplying solar panels for at least 10 years
  • Have the financial and market strength to be able to honour the long-term warranty

As with most industries that have grown rapidly in the past (such as televisions, computers, cars etc), we are starting to see a growing consolidation in the number of manufacturers and it is likely that within the next few years, we will see the industry dominated by the top handful of suppliers even more so than what it is today. For this reason alone, it is worth selecting panels from any one of the world’s leading brands rather than the smaller or newer ones.
