550 W | LONGI-PANEL-550W-LR5-72HTD-550M-(HI-MO-6)
The LONGi LR5-72HPH-550M is a powerful, high-efficiency monofacial solar panel designed for both residential and commercial installations. Offering a maximum output of 550W, it utilizes advanced PERC monocrystalline technology to optimize performance and energy yield. This panel is part of the Hi-MO 5 series, known for its high conversion efficiency and durability.
Key Features:
  • Power Output: 550W
  • Efficiency: 21.7%
  • Open Circuit Voltage (Voc): 49.80 V
  • Short Circuit Current (Isc): 13.98 A
  • Max Power Voltage (Vmp): 41.95 V
  • Current at Maximum Power (Imp): 13.12 A
Durability:
The LR5-72HPH-550M is designed to withstand harsh environments, including heavy snow loads up to 5400 Pa and wind loads up to 2400 Pa, making it suitable for extreme weather conditions. Additionally, it comes with an IP68-rated junction box, providing excellent protection against water and dust.
The PERC technology reduces power degradation, ensuring a first-year degradation of less than 2%, followed by a linear degradation of 0.55% per year up to 25 years. This makes the panel an ideal long-term investment for anyone looking to reduce energy costs while maximizing their solar energy production.
The LONGi LR5-72HPH-550M is built for longevity and reliable performance, backed by a 12-year product warranty and a 25-year linear performance warranty. This makes it a robust choice for projects seeking both high output and efficiency over the long term.
