Production Information

◆ Suitable for distributed projects

M6 Gallium-doped Wafer .9 busbar Half-cut Cell

Excellent outdoor power generation performance

High module quality ensures long-term reliability

Advanced module technology delivers superior module efficiency


(1) Longi Half-cut module Solar Panel meet the 1500V system voltage design requirements, which can reduce the system-side cost by about 10%;
(2) Effectively reduce the loss of power generation caused by occlusion when there is shadow occlusion and ash accumulation or snow accumulation.
(3) Reduce the first year and the average photoinduced attenuation;
(4) 100% PID Free






PECR Technology



PERC Cell

The PERC cell has a passivated rear side

and a laser grooving process, which significantly

improves the cell efficiency.


Lower Shading Loss
Because of the unique parallel connection
design, half-cell modules still have 50%
power output under the circumstance of array
shading in sunrise or sunset when portrait
installation.



Lower Operating Temperature

Half-cut cells have half of the working current,
thereby the thermal loss is remarkably
reduced. Operating temperature
correspondingly decreases, and the reliability

of module is improved as well as power gain.



Higher Energy Yield

Under high rradiation conditions,

half-cell module, especially bifacial half-cell module,

will have a higher energy yield compared with conventional module.

Bitacial half-cell module will help to achieve the lowest LCOE in

regions which is rich in sun radiation resources.
