M9-M12 Round Wire
The cross saction is circular. Compared with the traditional 3BB and 5BB technologies, the Multi-Busbars technologies components can reduce the effective shading area by 30%, reducing the Strings resistance loss at the same time and eventually increase the total power of the components by more than 5%, it also reduce the amount of conductive silver paste by more than 20%.
