Higher Durability

The muti-busbar design can decrease the risk of the sell micro-cracks and fingers broken.

High Power Density

High conversion efficiency and more power output per square meter, by lower series resistance and improved light harvesting.

Half-cell Design

Less energy loss cased by shading due to new cell string layout and split J-box,and lower cell connection power loss due to half-cell design.

Power guarantee

First year attenuation ≦ 1%, 2-25 year anual attenuation ≦ 0.4%

Large size cell

The large cell design effectively increases module peak power and effectively reduces BOS costs, thereby reducing system costs.
