Canadian Solar 355W Solar Panel 144 Cell CS3U-355P Commercial 780 panels per Container

Among the newest offerings of Canadian Solar, CS3U is part of the 355P series. These panels use state-of-the-art technology to achieve high efficiency and dependability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

Another advantage is the half-cut cell technology. CS3U has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. At 17.89% efficiency, CS3U offers surprising performance for its weight and size. Canadian Solar provides a 10-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

More energy and efficiency

The PERC technology further improves an already excellent efficiency of 17.89 percent. A reliable PID resistance and a unique glass lamination were added by the maker, which ultimately produced a model that was effective and extremely durable. CS3U produces 355 W of power under typical test settings.

Improved performance at hot temperatures

A high temperature coefficient translates to more energy as the temperature rises. Every 1.8°F increase over 77°F reduces the efficiency of your panel by just -0.39%.

Quality and reliability

CS3U receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Canadian Solar is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for a longer lifespan

These panels will lose no more than 2% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.55%. The module retains over 84.8% of its original output after 25 years. Guaranteed by Canadian Solar.

Improved frame design

CS3U design makes it suitable for both residential and business rooftops. The use of a strong 1.57" frame composed of Anodized aluminium alloy, crossbar enhanced boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.
