1.Higher Yield Due to Better Shading Response
Half Cell Module comprises two separated and identical solalr cell arrays, which means the ordinary strings of cells are cut into halves, and these shorter strings compose which has separated current paths. When a module is shaded, only one side shaded array's current will be impacted, while the other array will still be functionally producing power. Under this circumstance, when a module is shaded, the affected working areas of Blade will be 50% less.
By cutting solar cell into halves, the internal power loss will be lower and hot spot effect will also be reduced.

2.Less Mismatch Loss
Instead of 6 internal strings of cells, half cell module has 2*6 shorter ones. This design effectively deals with the mismatch
happened between cells caused by shadow, out of sync performance degradation, etc.
