Canadian Solar CS3K-320MS Solar Panel

The new CS3K Mono-PERC modules from Canadian Solar are the latest innovation from this well respected solar panel manufacturer. These monocrystalline modules feature the Mono-PERC 120 half cells which are designed to improve both efficiency and reliability.

The KuPower module series has improved shade tolerance, low temperature coefficient, and high PTC ratings of up to 93.11%.

These solar panels are the ideal solution for residential rooftop installations. Through maximizing the light absorption area, they have better shading tolerance and the module efficiency is maximized.

One of the main advantages of the new PERC cells is better energy performance, even on cloudy days, and during morning and evening hours. If a photon of light misses the cell, it can be reflected back and get a second chance at producing power.
