5 or 9 Bus Bar Technology

The 5 or 9 Bus Bar technology reduces the internal resistance of the panel. This facilitates the flow of current and therefore reduces losses. This effectively increases the efficiency of the panel when converting energy from solar to electrical.

In a solar panel there is a thin strip of copper or aluminium between the cells that produce electricity. This strip separates the solar cells and transfers the direct current collected by the photons to the solar inverter. The solar inverter in turn converts direct current into a useful alternating current.

The solar channels (Bus Bars) have an important purpose, to transmit the direct current generated by the incoming photons. Today there are significant losses when feeding the cells.

During the process of soldering the conductors to the solar cells, in order to be assembled in solar panels, a percentage of the remaining voltage is left behind in the cells. Over time, the residual voltage turns into micro-cracks that ultimately reduce the life of the panel and its performance, respectively.

Due to the shorter distance between the channel bars in 5 or 9 BusBar hives, residual voltages are less than 10%. Thus, with the technology of 5 or 9 Bus Bar, higher efficiency and longer life are ensured.
