Half Cell and Twin Panel Technology

Half cut cell + twin panel technology consists of cutting the solar cell in half with a non-destructive infrared laser.

This technology halves the electrical current of the cell and effectively reduces the internal electrical resistance in the cell strip and increases the module power by 2%. The twin-panel design minimizes power loss in shading conditions, thereby improving system incompatibility and increasing the efficiency of the PV system.

Low Temperature Heat Point

By halving the electric current of both cells and cell arrays, the hot spot heat can be reduced by 50%, increasing the durability of the PV module.

Low Temperature Operation

Since the half-cut cells only have half the operating current, the thermal loss of power of the PV module during operation can be reduced by 25%. It increases the durability and overall power output of the PV module when the operating temperature of the PV module is low.

Low Shading Loss

The twin section arrangement of cell arrays in a PV module ensures that the module continues to produce at least 50% of the total energy even when part of the module or cell array is shaded.

Multi-Busbar Technology

Compared to the traditional 5BB design, the innovative MBB design on the cell can shorten the current-collection cross path by 50%, thereby significantly reducing the cell internal resistance, which contributes to a 1% – 1.5% increase in power output.

Compared to 5 busbar design. MBB design can also reduce performance loss in case of cell microcracks and finger electrode erosion from external factors.

Another advantage of the MBB design is the improved light absorption thanks to the round strip application. Compared with the traditional flat strip design of 5BB, the round strip light design increases the power output of the PV module by 1% – 1.5%.
