3 Busbar Vs 5 Busbar Solar Cell

Soldered in both ends first 4.

3 busbar vs 5 busbar solar cell. Soldering flux in syringe injector 3. Using 45 watts soldering iron with flattened tool tips 2. However to achieve even higher efficiencies the latest trend is to have 4 busbars and sometimes even 5 busbars. 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.

The older practice was to have solar cells with typically 2 busbars. It is easy to distinguish in appearance. 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. Side by side comparison of solarworld s 3 busbar sunmodule solar panels left versus the 5 busbar one right.

Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell. These metallic contacts are called busbars and have a significant purpose. They conduct the direct current generated by the solar photovoltaic cell. Higher output per cell higher efficiency.

So what does this exactly mean for the generation of your solar plant. Their purpose is to conduct electricity generated by solar cells and move it to the junction box. 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. 1 2x 6 5 x 6 5 inc fly wood.

Multi busbar cells noticably 5 busbar 5bb cells are currently one of the major trends in solar cell and module design. The 12 pcs busbars is also called multiple busbars referred to as mbb. Frequently solar cell busbars are. Solarworld s five busbar 60 cell panels have approached the nameplate power of competitors 72 cell presumably three or four busbar panels.

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. As a solar installer you may have come across 4bb 3bb 2bb on solar panel data sheets. What are busbars busbars are metalised thin strips printed on the front and back of the solar pv cell. 4bb implies it is a module with 4 bus bars.
