Description
The LONGi Hi-MO 7 620W Bifacial Solar Panel (Model: LR7-72HGD-620M) is engineered for high-performance energy generation in utility-scale and commercial applications. Featuring N-type TOPCon (Tunnel Oxide Passivated Contact) cell technology, it achieves a remarkable module efficiency of up to 23.0%, ensuring optimal power output even in challenging conditions .
Its bifacial dual-glass construction allows the panel to absorb sunlight from both the front and rear sides, increasing overall energy production, especially when installed over reflective surfaces. The robust design includes 2.0mm tempered glass on both sides and an anodized aluminum frame, providing enhanced durability and resistance to environmental factors .
