210mm Mono Solar Cell

210mm large-size silicon wafer and monocrystalline PERC cell, it comes with several innovative design features allowing high power output of more than 600W. Excellent temperature coefficient and low irradiation performance brings the greater power. Furthermore, benefit from square mono cells and high-density encapsulation technology, the efficiency of panels can reach up to 21.2%.
