TECHNOLOGY COMPARISON
Compared with conventional module, MWT modules reduce 3% shaded area with no busbars. MWT module technology replaces string ribbon by conductive back sheet, abandoning strain, micro-crack and results power degradation, greatly improving stability and reliability.
MWT
Positive and negative electrodes are both on the rear side of solar cell
Conventional
Positive and negative electrodes are located on opposite sides of the cell
MWT
Busbar-free design exhibits higher power output by decreasing shading area up to 3 %
Conventional
Conventional design covers more cell surface from the main busbars, therefore the power output is limited
Replace conventional soldering with conductive foil and 2D encapsulation structure
Conventional Cells connected by string ribbons
