Multi-busbar Technology

Multi-Bus Bar (MBB) technology can effectively improve cell efficiency and reduce CTM packaging losses, thereby increasing module power. Under STC (irradiation is 1000W/m2), the power gain of multi-bus grid components mainly comes from two aspects: electrical gain-multi-bus grid shortens the current transmission distance of the thin grid line, reduces the series resistance Rs, and then reduces the resistance loss ; Optical gain-MBB can effectively reduce the shading area of the grid line and increase the light-receiving area of the solar panel.





JA Certificate


JA Authority Certificate

Sunpal is one of the biggest distributor of JA Solar. JA solar panels have performed better than most of the solar panels.Their module products include: mono, poly, high power and half cut cell.High-power modules typically have higher efficiency ratings than low-power modules, and in addition, half-cut cell technology reduces the chance of hot spot -- this improves the daily performance of solar panels and the efficiency of the system.
