Busbar Solar Panels

The purpose of busbars in solar cells is to conduct the electric dc power generated by the cell when photons hit the cells.

Busbar solar panels.

They conduct the direct current generated by the solar photovoltaic cell. As you add more busbars the idea is that more electrons are able to pass through and power and efficiency increases. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. Busbars wire solar cells together to create higher voltages.

Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell. These metallic contacts are called busbars and have a significant purpose. The maximum amount of current that can be safely carried is determined by the size of the 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.

They make easier to distribute power. It can be as small as 10 mm2. Suntech s one busbar improvement generates five more watts per panel than its traditional three busbar models. Usually solar cell busbars are made of a silver paste or similar high conductivity materials.
