Busbar Solar Panels

Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell.

Busbar solar panels.

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. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar. The mission solar 305w perc 60 5 busbar solar panel is a 60 cell solar panel featuring a sleek all black design coupled with 5 busbar technology the efficiency and reliability make it ideal for utility grid tied installations including commercial and residential rooftop solar panel systems. Busbars wire solar cells together to create higher voltages.

These contacts the busbars and the fingers are printed onto the surface via a technology called screen printing. They conduct the direct current generated by the solar photovoltaic cell. The purpose of busbars in solar cells is to conduct the electric dc power generated by the cell when photons hit the cells. As you add more busbars the idea is that more electrons are able to pass through and power and efficiency increases.

Suntech s one busbar improvement generates five more watts per panel than its traditional three busbar models. The maximum amount of current that can be safely carried is determined by the size of the busbar. Usually solar cell busbars are made of a silver paste or similar high conductivity materials. 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.
