Product Desciption

9bb half cell mono pv solar panel 450w 460w 470w perc solar module 480wp 475wp 470wp 460wp solar panels

Perc Monocrystalline module 144 cells 166mm

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.

Half-cell design brings higer efficiency:

1.New cell string layout and split J-box location to reduce the energy loss casused by shading between modules

2. Low thermal certificates for greater energy production at high operating temperature

3. Low cell connection power loss due to half-cell layout (144 monocrystalline pv module)
