The series integrates 166mm silicon wafers with PERC, half-cell technologies. Our 9BB design improves current collection capability. The power of half-cell module increases, and the hot spot risk reduces because of lower working current. Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module. Better Weak Illumination Response, more power output in weak light condition, such as haze, cloudy, and early morning.
