3 Busbar Vs 5 Busbar Solar Cell

4bb implies it is a module with 4 bus bars.

3 busbar vs 5 busbar solar cell. The older practice was to have solar cells with typically 2 busbars. 1 2x 6 5 x 6 5 inc fly wood. The 12 pcs busbars is also called multiple busbars referred to as mbb. Soldered in both ends first 4.

Using 45 watts soldering iron with flattened tool tips 2. The busbars are the metal lines you see going down the individual squares or cells of the solar panel. They conduct the direct current generated by the solar photovoltaic cell. 4 busbar solar cell 4bb stands for 4 pcs busbars on a single cell and 5 busbar solar cell 5bb stands for 5 pcs busbars on a single cell.

Higher output per cell higher efficiency. Their purpose is to conduct electricity generated by solar cells and move it to the junction box. 4 bus bar cells are the latest technology in the market and they have several benefits over 3 bus bar or 2 bus bar modules. Silicon module super league member ja solar are in the process of moving their entire pv module portfolio to the most recent 5 busbar technology.

Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right. What are busbars busbars are metalised thin strips printed on the front and back of the solar pv cell. It is easy to distinguish in appearance. Many large pv module manufacturers such as solarworld and trina solar increasingly focus their production on solar pv modules using passivated emitter rear contact perc solar cells with 5bb frontside contacts.

Soldering flux in syringe injector 3. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. However as the technology evolved and the industry moved towards higher efficiencies the busbars in most solar cells were increased to 3 busbars. So what does this exactly mean for the generation of your solar plant.

However to achieve even higher efficiencies the latest trend is to have 4 busbars and sometimes even 5 busbars. Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell. Frequently solar cell busbars are. As a solar installer you may have come across 4bb 3bb 2bb on solar panel data sheets.
