Busbar Solar Panels

Suntech s one busbar improvement generates five more watts per panel than its traditional three busbar models.

Busbar solar panels.

In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. The maximum amount of current that can be safely carried is determined by the size of the busbar. They make easier to distribute power. They conduct the direct current generated by the solar photovoltaic cell.

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. These contacts the busbars and the fingers are printed onto the surface via a technology called screen printing. As you add more busbars the idea is that more electrons are able to pass through and power and efficiency increases. Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell.

Busbars wire solar cells together to create higher voltages. The purpose of busbars in solar cells is to conduct the electric dc power generated by the cell when photons hit the cells. It can be as small as 10 mm2. 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.
