LONGi LR7-72HVD-645M is a high-efficiency module from the latest Hi-MO X10 series in the Double Glass version, designed for maximum yields in large installations. The module achieves a powerful peak power of 645 Wp, allowing for the generation of a massive amount of energy from available commercial or ground-mounted space. Module with a 30 mm frame.\n\n----- HPBC 2.0 TECHNOLOGY (BACK CONTACT) -----\nThe module is made using breakthrough HPBC 2.0 – High Performance Back Contact technology, which means transferring all electrical contacts to the back of the cell. Eliminating front busbars provides a uniform front that increases light absorption and minimizes energy losses, translating to higher efficiency.\n\n----- EXTREME PERFORMANCE AND DURABILITY -----\nThe advanced glass-glass (Double Glass) design using tempered glass provides the highest protection for cells against microcracks and aging. The module features solid mechanical resistance, withstanding a snow load of up to 5400 Pa on the front and a wind load of up to 2400 Pa on the back. According to the specification, the panel has a fire resistance rating of IEC Class C (UL type 29).\n\n----- LOWER LOSSES AND LONGEVITY -----\nThanks to the BC cell architecture, the module operates at a lower temperature, which drastically reduces power drops during summer heatwaves. The very low temperature coefficient of -0.260%/°C ensures stable power production even in full sun. The system is also fully resistant to LID and LeTID degradation phenomena.\n\n----- LINEAR POWER DEGRADATION WARRANTY -----\nLONGi offers a 15-year product warranty and a 30-year linear power warranty, confirming the highest reliability of the double-glass version. First-year degradation is below 1%, and in subsequent years just 0.35% annually. As a result, after 30 years of operation, the module retains as much as 88.85% of its initial power.
