LONGi Hi-MO 7 High-Power Bifacial Double-Glass Solar Module (540W / 545W / 550W / 555W class)
Power your projects with a high-output LONGi module designed for modern commercial, industrial, and ground-mounted solar systems. This offering focuses on high wattage per panel, bifacial energy gain, and a double-glass structure for enhanced durability in demanding outdoor environments. As your direct supplier, we deliver consistent project batches, export-safe packing, and the documentation support you need for smooth installation and commissioning.
Why choose this module
-
Higher watts per panel: Reduce module count per MW and simplify installation planning.
-
