LONGi MONOCRYSTALLINE TOPCon PV MODULE LR8-66HYD

LONGi’s latest generation of photovoltaic modules is built on its self-developed HPBC (Hybrid Passivated Back Contact) cell technology. This breakthrough design eliminates front-side grid lines, presenting a sleek, pure black appearance that not only enhances aesthetics but also maximizes light absorption and photovoltaic conversion efficiency. Through refinements in internal cell structure and passivation processes, HPBC technology significantly increases module output power, with conventional HPBC cell efficiency exceeding 25.5%, and advanced HPBC+ cells surpassing 25.8%, setting new benchmarks for high-efficiency solar technology. LONGi’s HPBC portfolio includes the Hi-MO X9, designed for utilityscale and distributed projects with record-high output and enhanced safety and reliability features, and the EcoLife series, tailored for residential rooftops with refined aesthetics, compact 54-cell design, and strong performance under challenging conditions such as shading, snow, or low light—both backed by industry-leading long-term warranties.
