BackgroundWith the development of cell busbar technology, we can find that it can not only reduce cost but
also improve efficiency.
MBB will become mainstream in the Future
• Aesthetic appearance
• Reducing the shading area of about 3%
MBB grid pattern technology
• Reducing the Rs by 11%
• Optimizing the current transmission path and reducing
the risk of cell crack
MBB 4/5BB
• Improving utilization of sunlight because of round photovoltaic
solder strip multi-reflection

Higher reliability
Lower risk of hot-pot
• The hot spot temperature is lower about 20℃ than
5BB modules
• Significantly lower risk of hot spot
Aging performance
• DH2000 power loss <5%
• TC400 power loss <5%
Mechanical load test
• 5400Pa test power loss <3%
