3 busbar vs 5 busbar solar cell.

So what does this exactly mean for the generation of your solar plant. Silicon solar cells are metalized with thin rectangular shape strips printed on the front and back sides of a solar photovoltaic cell. 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. They conduct the direct current generated by the solar photovoltaic cell.

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. However to achieve even higher efficiencies the latest trend is to have 4 busbars and sometimes even 5 busbars. 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. The older practice was to have solar cells with typically 2 busbars.

The busbars are the metal lines you see going down the individual squares or cells of the solar panel. Their purpose is to conduct electricity generated by solar cells and move it to the junction box. 4bb implies it is a module with 4 bus bars. Higher output per cell higher efficiency.

It is easy to distinguish in appearance. What are busbars busbars are metalised thin strips printed on the front and back of the solar pv cell. Using 45 watts soldering iron with flattened tool tips 2. Soldered in both ends first 4.

Solarworld s five busbar 60 cell panels have approached the nameplate power of competitors 72 cell presumably three or four busbar panels. Solarworld s new solar panels use passivated emitter reach cell perc technology and two additional busbars to boost power by 2 and increase efficiency. Soldering flux in syringe injector 3. However as the technology evolved and the industry moved towards higher efficiencies the busbars in most solar cells were increased to 3 busbars.

As a solar installer you may have come across 4bb 3bb 2bb on solar panel data sheets. The 12 pcs busbars is also called multiple busbars referred to as mbb. Multi busbar cells noticably 5 busbar 5bb cells are currently one of the major trends in solar cell and module design. 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.
