Description
xLONGi Hi-MO 5 550W Monocrystalline Solar Panel (LR5-72HPH-550M)
The LONGi LR5-72HPH-550M is a high-efficiency 550W monocrystalline solar panel from the industry-leading Hi-MO 5 series. Engineered with 144 half-cut cells and Gallium-doped M10 wafer technology, this module delivers up to 21.3% module efficiency, exceptional low-light performance, and long-term reliability for residential, commercial, and utility-scale solar arrays.
Key Features & Highlights
- High Output Power: Delivers 550 Watts of nominal power using advanced M10 (182mm) Gallium-doped monocrystalline wafers.
- Half-Cut Cell Architecture: 144 half-cell design reduces internal resistive losses, lowers operating temperatures, and improves shade tolerance.
- Gallium-Doped Tech: Overcomes Light-Induced Degradation (LID) to ensure long-term energy yield and stable power production.
- Heavy-Duty Mechanical Rating: Built to withstand front-side snow loads up to 5400 Pa and rear-side wind loads up to 2400 Pa.
- PID Resistance: Advanced cell technology and anti-PID encapsulation minimize potential-induced degradation over time.
