Longi Hi-MO 7 615W Bifacial Dual-Glass Solar Panel (LR7-72HGD)

The Longi Hi-MO 7 615W solar panel (LR7-72HGD) is a high-performance photovoltaic module engineered specifically for utility power plants and large-scale industrial projects. Powered by advanced HPDC cell technology, this module delivers superior efficiency and power output , reaching a remarkable module efficiency of 22.8% for the 615W model. This ensures that your solar panels system achieves an exceptionally high energy yield.

At Enon Traders, we recommend the Longi Hi-MO 7 series because of its outstanding resilience in hot climates. It features an excellent power temperature coefficient of -0.280%/°C and a half-cell design that ensures a lower operating temperature. The module is constructed with 2.0+2.0mm semi-tempered dual glass , offering high bifaciality that can provide up to a 25% power gain from the rear side depending on your installation surface. For a complete industrial setup, pair these robust modules with our high-capacity solar inverters and solar batteries.
