Solar Panel Bus Bar

Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right.

Solar panel bus bar.

They are the wires that connect each cell to the other allowing the current to flow. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. Since each cell is generally just over a. 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. 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.

The most common solar cell design involves 2 or 3 full line busbars printed onto the cell. Solar busbar development trends and future. The busbars are the metal lines you see going down the individual squares or cells of the solar panel. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar.

5bb busbar solar cells. 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.
