Show series description

The Longi Solar Hi-MO X10 Scientist LR7-60HVH 535~560M series is designed to maximize energy yield from every square meter – especially in locations with limited roof space or where high power in a compact format is essential. A key feature is the application of back-contact (BC) technology in the enhanced HPBC 2.0 architecture, which translates to better performance under strong sunlight and an attractive, uniform front appearance without visible busbars. The modules utilize N-type cells, which help minimize power losses over time and maintain high efficiency for an extended operational lifespan. An additional benefit is the lower operating temperature, crucial during summer months and on roofs with poor ventilation – more energy reaches the inverter instead of being converted into heat. This series is suitable for residential and commercial installations, as well as projects requiring enhanced mechanical durability and flexible mounting methods while ensuring high reliability.
