JA Solar 550W 144 Half-Cell Bifacial Solar Panel

The JA Solar 550W 144 Half-Cell Bifacial Solar Panel delivers powerful and efficient energy generation designed for modern commercial, industrial, and utility-scale systems. Featuring PERC monocrystalline technology and a bifacial glass-glass design, it captures sunlight from both sides, maximizing energy yield and reducing the overall cost per watt.

Engineered with multi-busbar (MBB) technology and half-cell architecture, this panel provides higher output, lower internal losses, and greater shade tolerance—ensuring reliable performance even in challenging environmental conditions.
