Solar panel bus bar.

In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. Since each cell is generally just over a. Bus bars ground bars installation supplies residential northern arizona wind sun. Solar busbar development trends and future.

They are the wires that connect each cell to the other allowing the current to flow. 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. 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. The busbars are the metal lines you see going down the individual squares or cells of the solar panel.

5bb busbar solar cells. 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. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. Five busbars 5bb cells are currently one of the leading trends in solar cell and module design.
