LONGi panels adopt the recent innovation of ‘half-cut’ or ‘half size’ cells rather than full size square cells. Moving the junction box to the center of the module. Half-cut cell technology is to cut the cell into two separate parts by mature infrared laser, hence halve the working current. The thermal loss on the ribbon will be remarkably reduced and the module’s power increases by 2%. The reliability of module is also enhanced.
a) PERC cell Technology
The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency.
b) Half-cut cell technology increases power output by 2% and enhances the reliability of the solar module
- Low LID mono PERC half cut Technology
- High module conversion efficiency
- Slower power degradation
- Solid PID resistance
- Reduced resistive loss
- High energy yield
- Reduced hot spot risk
