PV Bus Bar

PV bus bar is a strip of COPPER that conducts electricity within a module or string of cells. It is installed around the perimeter of the solar panels. PV bus bar connects interconnect RIBBONs to the junction box for final output.
Interconnect RIBBONs can be considered like roads stretching across cells while the bus bars are like highways connecting the tabbing PV RIBBONs together.
