Canadian Solar CS6W-550MS (35mm frame)
As a result of the design and technology used, the CS6W-MS series panels achieve higher performance. The lower operating temperature guarantees higher energy gain. The panels in this series use dual cell technology. The cells are half the width, so they lose less energy. The panels are cross-sectioned. The two halves operate independently of each other. When one half is shaded, the other half still works. They are therefore more tolerant of partial shading.
Warranty can be extended to 15 years.
