420 Watts 182*91mm Efficient Solar Panels With 3 Bypass Diodes 30/35mm Frame

Mono 420W 182mm Sunpower Solar Half Cell Panel with 3 Bypass Diodes and 30/35MM Frame

Higher Yield Due to Better Shading Response

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. 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.
