JA Solar Panel 545W MBB Half-cell Module

The JA Solar 545W MBB Half-Cell Module is a high-performance monocrystalline panel built to deliver consistent output and streamline balance-of-system costs in commercial and utility-scale solar projects. Utilizing advanced Multi-Busbar (MBB) half-cell technology and achieving a module efficiency of 21.1%, it provides solid power density for installations where dependable yield and efficient use of space are top priorities.

With an open-circuit voltage (Voc) of 49.75V, a short-circuit current (Isc) of 13.93A, and a maximum power voltage (Vmp) of 41.8V, the module sustains stable electrical performance across changing conditions. Its half-cell layout reduces resistive losses and enhances tolerance to partial shading, while the current at maximum power (Imp) of 13.04A ensures effective energy capture throughout the day.

Measuring 2279×1134×35 mm and weighing 27.2 kg, the panel is built for straightforward handling and compatibility with standard mounting hardware. Its durable frame and proven monocrystalline construction make it a reliable, long-lasting choice for large-scale solar deployments seeking steady performance and simplified logistics.
