FAQ
About product
CS3U is part of the 350P Series — one of the most recent made by Canadian Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 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. Not surprisingly, the efficiency of this module is quite high – 17.64%. Canadian Solar paid as much attention to durability as they did to performance. CS3U is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 10 years.
The highest power output is guaranteed by Canadian Solar CS3U with an efficiency of up to 17.64%. Such outstanding performance is the product of PERC technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.
Even under extreme heat, CS3U maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.39% of efficiency for every 1.8°F over 77°F.
CS3U is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.
Canadian Solar guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.55% every year after that. After the 25 years are over, your modules will retain at least 84.8% of their original performance. This 350 W Canadian Solar solar panel also comes with a substantial 10-year product warranty.
This module is weatherproof due to the 1.57" frame manufactured from Anodized aluminium alloy, crossbar enhanced and a layer of safety tempered glass. The modules' front and rear sides can withstand loads of 5400 and 2400 Pa, respectively.
