Solar Panel Busbar

5bb busbar solar cells.

Solar panel busbar.

You will nowadays still find the majority of all pv modules using such 3 busbar 3bb cells as they are commonly abbreviated. Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right. 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. The most common solar cell design involves 2 or 3 full line busbars printed onto the cell.

Five busbars 5bb cells are currently one of the leading trends in solar cell and module design. 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. If we exceed the rating of the busbar without regard to the 120 rule we are creating a scenario where we are feeding a panel board with too much energy and have nothing in place to prevent the sum of the loads in that panel from drawing more current than the busbar can handle. Bus bars ground bars installation supplies residential northern arizona wind sun.

Solar busbar development trends and future. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. They are the wires that connect each cell to the other allowing the current to flow. This diy camper van busbar system is a great way to keep the main fuses nice and organized in a small space giving your camper van solar install a profession.

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