A PV bus bar is a COPPER strip used to conduct energy inside a string of cells or module. It is positioned all the way around the solar panels. For the final output, a PV bus bar links RIBBONs to the junction box.
While the bus bars serve as highways linking the tabbing PV RIBBONs together, interconnect RIBBONs can be thought of as roadways that extend across cells.
