Canadian Solar Inc. is a publicly traded company (NASDAQ: CSIQ) that manufactures solar power modules and solar power systems.

Company history[edit]

Founded in 2001 in Ontario, Canada, by Shawn Qu, Canadian Solar is one of the world's largest solar companies. Canadian Solar has been publicly traded on the NASDAQ (CSIQ) since 2006. The company is a vertically integrated provider of ingot, wafer, solar cell, solar module and other solar applications. In 2013 it shipped 1.9 GW of photovoltaic panels and reached a production capacity of over 2.4 GW.[citation needed]

Canadian Solar has offices in Canada, Germany, Italy, Spain, United Arab Emirates (U.A.E), South Africa, Israel, Japan, Korea, Australia, the United States, Singapore, Hong Kong and Chinese mainland.[1]

In 2011, the company ranked fifth largest producer in the world by PVTECH.[2] IMS Research ranked them third in quarterly shipments (MW) for Q4 2012.[3]

In 2014, the company ranked fourth largest producer in the world by PVTECH.


Canadian Solar production facilities are structured for vertically-integrated manufacturing of ingots, wafers, solar cells, solar PV modules, solar power systems and specialized solar products.

In 2008, Canadian Solar was one of the first module manufacturer to have an onsite ISO/IEC 17025 compliant testing laboratory. The Canadian Solar Photovoltaic Testing Lab was established to ensure compliance with international safety and reliability testing standards for solar panels.[citation needed]

The bulk of Canadian Solar's manufacturing facilities are located in China. In 2011, Canadian Solar also began manufacturing in a plant in Ontario, Canada.[4] The Ontario plant with a production capacity of over 500 MW per year[3] employs several hundred workers and its products are compliant with Ontario's feed-in tariff domestic content provisions.[5]

Canadian Solar passed the OHSAS 18001 international standards for occupational health and safety after auditing by TUV Rheinland in 2012.[6]

Canadian Solar offers solar modules, solar power systems and specialized solar products.


Canadian Solar's standard modules are powered by 125 x 125mm (5 inch) or 156 x 156mm (6 inch) high efficiency mono-crystalline or poly-crystalline solar cells. The ELPS CS6P-MM module, uses Canadian Solar's ELPS mono cells and metal wrap through (MWT) design to allow for more light absorption per cell. ELPS modules deliver 10% more electricity than conventional solar modules.[citation needed] Their mono ELPS solar cell efficiency is 21.1%, placing it among the highest P-type mono-crystalline cell efficiencies in the industry.[citation needed]

Performance and reliability[edit]

Canadian Solar products adhere to international quality standards, including IEC 61215, IEC 61730, UL1703, KEMCO, CE, JET and MCS.[citation needed]

Canadian Solar modules have achieved the maximum ratings in tests for ammonia (NH3) resistance of solar modules[citation needed] and have also passed IEC 61701 salt mist resistance testing and are highly PID resistant.[citation needed]

Canadian Solar modules rank highly under PVUSA test conditions (PTC).[citation needed]

Warranty and insurance[edit]

Canadian Solar was one of the first companies[8] in the industry to offer enhanced product and performance warranty backed by an immediately available and non-cancellable insurance policy.[citation needed]

In 2011, Canadian Solar introduced a linear performance guarantee for PV module power output over a 25-year period. Under this policy, Canadian Solar expanded its product warranty covering workmanship and material defects up to 10 years.[citation needed]
