Bus bars ground bars installation supplies residential northern arizona wind sun. You will nowadays still find the majority of all pv modules using such 3 busbar 3bb cells as they are commonly abbreviated. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. 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.

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. Solar busbar development trends and future. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. 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 are the wires that connect each cell to the other allowing the current to flow. An important point in solar cell design and production is to strike an optimal balance between busbar and finger resistance losses and shading and reflection losses the former caused by using too few metallic contacts thus creating greater distances between them and the latter being the consequence of too many contacts on the cell surface. 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.

5bb busbar solar cells. Five busbars 5bb cells are currently one of the leading trends in solar cell and module design.
