Half Cells 9bb Mono 400W 450W 500W 600W Solar Energy Panel
Perc Monocrystalline Module 144 Cells 166mm
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 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.
💡 Half-cell design brings higher efficiency:
- New cell string layout and split J-box location to reduce the energy loss caused by shading between modules.
- Low thermal certificates for greater energy production at high operating temperatures.
- Low cell connection power loss due to half-cell layout (144 monocrystalline PV module).
