Solar Panel Bus Bar

5bb busbar solar cells.

Solar panel bus bar.

Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. Solar busbar development trends and future. 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. 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.

Since each cell is generally just over a. The busbars are the metal lines you see going down the individual squares or cells of the solar panel. Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right. Bus bars ground bars installation supplies residential northern arizona wind sun.

They are the wires that connect each cell to the other allowing the current to flow. 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. You will nowadays still find the majority of all pv modules using such 3 busbar 3bb cells as they are commonly abbreviated. 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. The most common solar cell design involves 2 or 3 full line busbars printed onto the cell.
