LONGi Hi-MO 7 LR7-72HGD-620M

Hi-MO 7 is LONGi's latest generation of high-efficiency modules designed for the utility market. Hi-MO 7 boasts excellent power generation performance and product reliability, making it particularly suitable for applications with high albedo, high temperature, and limited space.

What is HPDC technology?

HPDC stands for High Performance and Hybrid Passivated Dual-Junction Cell, a bifacial dual-junction cell produced by hybrid passivation technology. Different passivation technologies are used on the front and back of this cell, effectively reducing carrier recombination and enhancing power generation capacity. This results in higher Voc and efficiency, lower degradation, and a better power temperature coefficient.

LONGi has earned the EcoVadis Gold Medal, placing it in the top 5% of companies assessed by EcoVadis for sustainability management and value-chain transparency.
