JA Solar Panel 550W MBB Half-cell Module

The JA Solar 550W MBB Half-Cell Module is a high-performance monocrystalline PV panel engineered to deliver strong power density and reduce balance-of-system costs. With an advanced MBB (Multi-Busbar) half-cell architecture and a module efficiency of 21.10%, it offers dependable output for commercial and utility-scale installations where consistent energy yield and efficient space utilization are essential.

Built 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 maintains stable performance across changing conditions. The half-cell configuration minimizes resistive losses and improves tolerance to partial shading, while the current at maximum power (Imp) of 13.04A supports effective energy harvesting throughout the day.

Designed for straightforward deployment, the panel measures 2279×1134×35 mm and weighs 27.2 kg, making it compatible with standard mounting systems and practical for large-scale logistics. Its durable construction and proven monocrystalline cell technology ensure reliable operation over the long term, positioning the JA Solar 550W as a solid choice for demanding solar projects.
