LONGi Solar 615W Hi-Mo7 HPDC Bi-Facial Solar Module - Silver Frame

LONGi Solar 615W Hi-MO 7 HPDC Bi-Facial Solar Module (Silver Frame) – LR8-66HGD-615M

The LONGi Hi-MO 7 LR8-66HGD-615M is a high-output bifacial, dual-glass solar module designed for large commercial and utility-scale installations where energy yield, durability, and long-term performance matter. Using HPDC cell technology and a bifacial architecture, it can generate additional energy from reflected light on the rear side (site dependent), helping improve overall system yield without increasing roof/land area.

Built for demanding outdoor conditions, the dual-glass construction and strong mechanical load ratings support long service life, while LONGi’s long warranty profile underpins confidence in performance retention over decades.
