182mm Half cell mono solar panel power is 525W-550W with 144cells. Half cell solar panel is produced with the up-to-date technology in the design & manufacturing process, with excellent quality performance. Higher output power. Lower temperature coefficient. Less shading effect. MBB 182mm Half cell solar panel is produced with the up-to-date technology in the design & manufacturing process, with 144cells high efficiency half cell & excellent quality performance. Higher output power. Lower temperature coefficient. Less shading effect. By cutting solar cell into halves, the internal power loss will be lower and hot spot effect will also be reduced. Half Cell Module comprises two separated and identical solar cell arrays, which means the ordinary strings of cells are cut into halves, and these shorter strings compose which has separated current paths. 100% EL, Flash test before package and shipping.
