Solar Panel Bus Bar

Solarworld s five busbar 60 cell panels have approached the nameplate power of competitors 72 cell presumably three or four busbar panels.

Solar panel bus bar. 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. 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. 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.

They are the wires that connect each cell to the other allowing the current to flow. The most common solar cell design involves 2 or 3 full line busbars printed onto the cell. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right.

In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. 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. Bus bars ground bars installation supplies residential northern arizona wind sun.

Five busbars 5bb cells are currently one of the leading trends in solar cell and module design. They make easier to distribute power.
