Ultrahigh bifaciality, 20% more rear side maximum out power than PERC. Excellent lower temperature coefficient, 1%-2% more power generation than P-type modules in high temperature areas. Lower LCOE, 3.5% more power generation than PERC modules, greatly reduce the cost of power generation. 0~+5W positive power tolerance peak power output ensures the reliability of the module. The module shows excellent weak light performance in the morning, evening and cloudy days. Improved cell technology and selected materials make the module has good PID resistance.
