Smart Insights (data-driven)
  • Efficiency of 23.3% matches the Back Contact 600-650W median
  • 233.2 W/m² power density is 3.7 W/m² below Back Contact 600-650W median (236.9 W/m²) - requires larger installation area
  • At -0.26%/°C, hot weather performance is typical for Back Contact 600-650W panels
  • At 33.5 kg (1.1 kg above Back Contact 600-650W median of 32.4 kg), requires checking roof load capacity
  • 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces

Show series description

Longi Solar Hi-MO 9 is a breakthrough series of modules that redefines performance standards through the use of advanced HPBC 2.0 cell technology. This solution eliminates losses resulting from shading the front part of the cell by busbars, which directly translates into record efficiency and modern aesthetics. These panels are the ideal choice for investors seeking maximum energy yield from limited roof area, effectively solving the problem of space shortages in ambitious projects. Thanks to its optimized internal structure, Hi-MO 9 demonstrates exceptional resistance to degradation and stable operation even in low-light conditions, guaranteeing real gains on cloudy days. The innovative design also ensures an excellent temperature coefficient, limiting power drops during summer heat. This series is dedicated to both demanding households and large-scale solar farms, where the lowest levelized cost of energy is key. Compared to the competition, Hi-MO 9 stands out with a unique hybrid structure that combines the highest efficiency with long-term mechanical reliability. It is a safe and future-proof choice for anyone focusing on the highest quality of workmanship and the most modern technological thought in the photovoltaic industry.
