The LONGi Hi-MO 7 LR8-66HGD 595W-625W Bifacial Solar Module is a high-performance solar panel designed for utility-scale, commercial, and industrial solar power projects. Built with HPDC (Hybrid Passivated Dual Cell) technology, this module achieves higher efficiency (up to 23.1%) and superior power output.
With a bifaciality ratio of 80±5%, it captures additional energy from rear-side reflections, increasing overall power generation by 5-25%. The low temperature coefficient (-0.28%/°C) and lower operating temperature improve energy yields, especially in hot climates.
This panel is manufactured with dual-glass technology (2.0mm+2.0mm heat-strengthened glass), providing enhanced durability against environmental factors. The LONGi lifecycle quality assurance ensures long-term reliability, with only 1% power degradation in the first year and 0.4% per year from years 2-30.
Certified under IEC 61215, IEC 61730, UL 61730, ISO 9001, ISO 14001, and ISO 45001, the Hi-MO 7 module is designed to meet global quality and safety standards.
