Solar Panels

Canadian Solar was founded in 2001 in Canada. One of the top three solar power companies in the world, they have shipped over 21GW of photovoltaic modules since their inception. Canadian Solar is committed to providing high quality solar products, solar system solutions and services to customers around the world. The company operates three state-of-the-art PV research centers for cells, modules and systems in Canada and China. Combined, more than 400 scientists, engineers and technicians conduct research to continuously improve their solar technologies. Canadian Solar is a globally recognized innovator of the solar industry.

Canadian Solar‘s new SuperPower modules with Mono-PERC cells and KuMax split-cell modules significantly improve efficiency and reliability.  The innovative technology offers superior low irradiance performance in the morning, in the evening and on cloudy days, increasing the energy output of the module and the overall yield of the solar system. KuMax split-cell solar panels also perform better in shade than standard solar panels, due to lower power losses in the cell connection.
