A solar busbar is a thin strip of aluminum or copper found between cells in a solar panel. Its job is to separate solar cells and conduct the direct current the solar cells collect from solar photons to the solar inverter. The solar inverter then converts the direct current into a feasible alternating current.
Multi busbar cells, particularly five busbars (5BB) cells, are one of the most popular designs for solar cells and modules right now. The Multi-Busbars (MBB) approach aims to reduce resistive losses by reducing the amount of current in both the fingers and the busbars.
The common material for making busbars is silver-plated copper to enhance the conductivity on the front and to reduce oxidation at the back. Busbar is denoted by BB in solar cells. Since busbars influence the efficiency of solar cells, the number of busbars used in a solar cell varies depending on its efficiency.
9 busbars in solar panels mean that the module in the solar panels contains several cells with nine busbars. The more busbars the solar panels have, the more electricity they can conduct. Before this, there are also some other busbar-type solar panels in the market like 3BB, 4BB, and 5BB.
A solar panel with 12 busbar solar cells is termed a 12BB solar panel. These panels are more efficient than previously mentioned types of BB solar panels. With a 12-busbar technology the cell will have the least shaded area and its ribbon reduces reflected light. Thus, increasing the current is collected and flowing through the cell string.
In traditional panels, the distance of a single busbar from the main busbar is long, so if the panel power is damaged, the power of the panel is completely lowered. However, in the case of solar cells using 9BB/12BB technology, these distances are shorter. Consequently, when the busbar fails, the power of the panel will not be degraded much.
Solar Panel Busbars
In solar panels, busbars are the thin rectangular strips that separate solar cells and conduct electricity. It takes the electrons, once separated from photons by the solar cells, and transfers them to the panel''s inverter.

Maximum solar for 40'' bus with standard solar panel sizes
