A busbar is a metal strip or bar that allows you to pass more electrons through solar cells to create a higher amount of power and efficiency. Solarworld s five busbar 60 cell panels have approached the nameplate power of competitors 72 cell presumably three or four busbar panels. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency.

This diy camper van busbar system is a great way to keep the main fuses nice and organized in a small space giving your camper van solar install a profession. If we exceed the rating of the busbar without regard to the 120 rule we are creating a scenario where we are feeding a panel board with too much energy and have nothing in place to prevent the sum of the loads in that panel from drawing more current than the busbar can handle. You will nowadays still find the majority of all pv modules using such 3 busbar 3bb cells as they are commonly abbreviated. Bus bars ground bars installation supplies residential northern arizona wind sun.

The busbars are the metal lines you see going down the individual squares or cells of the solar panel. Since each cell is generally just over a. It separates solar cells and conducts the direct current the cells collect from solar photons to the solar inverter which converts the direct current into useable alternating current the maximum amount of current that can be safely carried is determined by the size of the. They make easier to distribute power.

In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. They are the wires that connect each cell to the other allowing the current to flow. Some sizeable solar panel manufacturers such as trina solar solarworld and csun increasingly focus their manufacturing on pv solar panels using perc solar cells with 5bb busbars. Five busbars 5bb cells are currently one of the leading trends in solar cell and module design.
