SolarKobo Score: 4/5
The makers of Canadian solar panel modules, Canadian Solar, was founded in 2001. Based in Guelph, Canada, and with about 14,000 employees and over 500 researchers and engineers, Canadian Solar is currently ranked as the fifth-largest solar panel manufacturer in the world by volume with over 8.5GW of solar panels produced in 2019 and about 52GW shipped since inception.
The bulk of Canadian Solar's manufacturing facilities are located in Canada and China. Its manufacturing plant at Ontario has a production capacity of over 500 MW per year. Canadian Solar also has production facilities in Indonesia, Vietnam and Brazil.
Canadian Solar performs nearly 400 internal quality tests on its cells and modules. Canadian Solar is publicly traded on NASDAQ.
Range of Solar Panels
Canadian Solar produces solar panels designed for residential, commercial and utility-scale applications. Like most other large volume brands, Canadian Solar has transitioned to using higher efficiency monocrystalline PERC half-cut cells in almost all its new generation panels. Canadian Solar also recently introduced a new range of bifacial solar panels.
Residential Solar Panels
In its range of residential solar panels, Canadian Solar offers the Ku, HiKu and HiDM ranges all of which are available in both polycrstalline and monocrystalline varieties with the HiDM in the shingled form. Panels in these two ranges are available from 295W to 335W for the Ku, 325W to 375W for the HiKu and 320 to 345W for the HiDM. Canadian Solar uses cast mono-crystalline PERC half-cut cells with either 5 busbars or multi-busbars (MBB). PERC stands for Passivated Emitter and Rear Cell or Passivated Emitter and Rear Contact.
PERC is a new technology that adds a dielectric passivation layer on the rear of the cell. The extra layer is to allow more sunlight to be captured and turned into electricity with the goal of increasing the efficiency of PERC cells over traditional solar cells.
