Busbars In Solar Panels

They are the wires that connect each cell to the other allowing the current to flow.

Busbars in 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. The busbars are the metal lines you see going down the individual squares or cells of the solar panel. They are the wires that connect each cell to the other allowing the current to flow. In a solar panel there s a thin strip of copper or aluminum between cells that conducts electricity called a busbar.

3 84 kw gridtied battery backup solar system with outback power center and 12x heliene 320 panels. These front and rear contact strips are referred to as busbars. Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back. Shop busbars terminal busbars and solar busbars at alte.

However bifacial panels are generally only beneficial over light coloured surfaces such as light sandy or rocky ground used in large mw scale solar farms located in more arid areas. Perpendicular to the busbars are the metallic and thinner grid fingers also called solar cell.

Suntech s one busbar improvement generates five more watts per panel than its traditional three busbar models. Solar busbars have one simple yet significant purpose. Commonly solar cell busbars are made of copper plated with silver. Call an alte expert today at 877 878 4060.

The busbars are the metal lines you see going down the individual squares or cells of the solar panel. 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. Bifacial panels featuring mbb are also growing in popularity due to the increased power output by utilising the rear side of the panel to achieve up to 20 or more power roughly 80w extra. The maximum amount of current that can be safely carried is determined by the size of the busbar.

As you add more busbars the idea is that more electrons are able to pass through and power and efficiency increases. Busbars wire solar cells together to create higher voltages. Since each cell is generally just over a half a volt the bus bars wire them together in series to create the higher voltages needed to be a usable solar panel. The silver plating is necessary to improve current conductivity front side as well as to reduce oxidization rear side.

Usually solar cell busbars are made of a silver paste or similar high conductivity materials.
