Longi Most Efficient Solar Panels 400 Watt Solar Panel Manufacturer

Longi Most Efficient Solar Panels 400 Watt Solar Panel Manufacturer

Production Information

(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.
