SAKO 550W PV module with 10bb half-cut mono Perc cell technology with multi bus-bar design, improved cells efficiency and get higher output power. The module efficiency up to 21.3%. Such panel can reduce energy loss caused by shading due to new cell string layout and lower cell connection power loss due to half-cell design. It can also have more power output in weak light condition such as cloudy, morning and sunset. Even in harsh environment they can works well. Lower operating temperature and temperature coefficient increases the power output. It is tested that 2% more power generation, lower LCOE. SAKO 550W PV module is the ideal choice for high quality power station and home system.- Please read returns policy for T&C's
