LONGi Hi-Mo X10 HVB 480W All Black Mono Solar Panel
The LONGi Hi-Mo X10 HVB 480W (LR7-54HVB-480M) is a premium all-black monocrystalline solar panel built on LONGi's next-generation HPBC 2.0 (Hybrid Passivated Back Contact, Generation 2) cell technology. Independently developed by LONGi, HPBC 2.0 represents a significant generational leap in back-contact cell design — eliminating front-side grid lines entirely for a sleek, uniform appearance while delivering up to 23.3% module efficiency.
Part of the Hi-MO X10 range — LONGi's flagship distributed market product — this panel is engineered for installers and homeowners who demand the very best in performance, reliability, and aesthetics.
