In solar panels busbars are typically flat strips which allow heat to dissipate more efficiently because of their high surface area to cross sectional area ratio. Over the last 6 months many of the industry s biggest players announced next generation panels with power ratings well above 500w.

Solarworld s five busbar 60 cell panels have approached the nameplate power of competitors 72 cell presumably three or four busbar panels. Solar busbars have one simple yet significant purpose. Silicon solar cells are metallized with thin strips printed on front and rear of a solar cell. Five busbars 5bb cells are currently one of the leading trends in solar cell and module design.

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. Solar power world is the leading online and print resource for news and information regarding solar pv installation development and technology. The purpose of busbars in solar cells is to conduct the electric dc power generated by the cell when photons hit the cells. They conduct the direct current produced by the solar cell from the incoming photons.

Some sizeable solar panel manufacturers such as trina solar solarworld and csun increasingly focus their manufacturing on pv solar panels using perc solar cells with 5bb busbars. Commonly solar cell busbars are made of copper plated with silver. They are the wires that connect each cell to the other allowing the current to flow. These front and rear contact strips are referred to as busbars.

Work with america s most trusted diy solar brand for do it yourself solar power. In the solar industry busbars are connected to solar panels by welded connections. The busbars are the metal lines you see going down the individual squares or cells of the solar panel. The silver plating is necessary to improve current conductivity front side as well as to reduce oxidization rear side.

In 2020 however a new battle has emerged to develop the world s most powerful solar panel. Shop busbars terminal busbars and solar busbars at alte. Have questions about the right busbar for you. 5bb busbar solar cells.
