450W Half Cell Solar Energy Panels
MSD132-450 MONO Half-cut Single Double Glass Module
MONO half-cut single glass module, assembled with muti-busbar PERC technique and half-cut structure, offer the advantages of higher power output, reduce shading effect on the energy generation, enhance the mechanical load bearing capacity as well.
Half-cell modules have solar cells cut in half, which improves module performance and durability. Traditional 60- and 72-cell panels will have 120 and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are reduced and the cells can generate more electricity. Smaller cells experience reduced mechanical stress and therefore less chance of cracking. Half-cell assemblies have higher output ratings and are more reliable than traditional panels.
C.DIVINE 470W-510W 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 21.02%. 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 535W-550W PV module is the ideal choice for high quality power station and home system.
