Busbar Solar Panels

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

Busbar solar panels.

They make easier to distribute power. The purpose of busbars in solar cells is to conduct the electric dc power generated by the cell when photons hit the cells. Busbars wire solar cells together to create higher voltages. As you add more busbars the idea is that more electrons are able to pass through and power and efficiency increases.

Usually solar cell busbars are made of a silver paste or similar high conductivity materials. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell. 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.

It can be as small as 10 mm2. These contacts the busbars and the fingers are printed onto the surface via a technology called screen printing. 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 conduct the direct current generated by the solar photovoltaic cell.
