LONGi LR7-72HVH-640M is a high-performance module from the latest Hi-MO X10 series, designed for peak efficiency in commercial and utility-scale installations. The module achieves a massive peak power of 640 Wp with an efficiency of 24.2%, allowing for the generation of tremendous amounts of energy from the available area. 30 mm frame module.
----- BC-CELL (BACK CONTACT) TECHNOLOGY -----
The module is manufactured using groundbreaking back contact cell technology (BC-CELL / Back Contact). Moving all electrical contacts to the rear side and eliminating front busbars increases light absorption and minimizes energy losses, while providing excellent, uniform front aesthetics.
----- EXTREME PERFORMANCE AND DURABILITY -----
The advanced design using 3.2 mm tempered glass effectively protects the cells against microcracks. The module is characterized by solid mechanical resistance, withstanding snow loads up to 5400 Pa on the front and wind loads up to 2400 Pa on the back. According to the technical specification, the panel has an IEC Class C fire rating.
----- LOWER LOSSES AND LONGEVITY -----
Thanks to the BC cell architecture, the module operates at a lower temperature, which drastically reduces power drops during summer heatwaves. A very low power temperature coefficient of just -0.260%/°C ensures stable power production even in full sun.
----- LINEAR POWER DEGRADATION WARRANTY -----
LONGi offers a 15-year product warranty and a 30-year linear power warranty. First-year degradation is under 1%, and in subsequent years just 0.35% annually. Thanks to such stable parameters, after 30 years of operation, the module retains up to 88.85% of its initial power.
