LONGi LR8-66HGD-615M, an advanced module from the Hi-MO 7 series, designed for maximum performance in modern installations. It utilizes an innovative Double Glass (glass-glass) design, allowing it to achieve a powerful peak power of 615 Wp with an efficiency of 22.8%. ----- ADVANCED HPDC AND BIFACIAL TECHNOLOGY ----- At the heart of the module is HPDC cell technology, which ensures higher efficiency and an excellent bifaciality factor of 80±5%. Thanks to its double-sided design, the panel absorbs light from both sides, allowing for significant additional energy yield depending on the albedo of the surface. The use of half-cut cells results in lower operating temperatures, which directly translates to longer component life. A very low temperature coefficient of power of -0.280%/°C guarantees high yields even on the hottest days. ----- EXTREME PERFORMANCE AND DURABILITY ----- The module's efficiency of 22.8% allows for generating massive amounts of energy while optimally utilizing available space. ----- MAXIMUM PROTECTION AND RELIABILITY ----- Double glass provides excellent insulation and full resistance to ammonia and salt mist corrosion, as well as PID degradation. The module has an IP68 protection rating and is equipped with three bypass diodes, which minimizes energy losses in case of partial shading. The panel also passed a rigorous hail resistance test with 25 mm diameter hail at an impact speed of 23 m/s. ----- 30-YEAR LINEAR POWER DEGRADATION WARRANTY ----- LONGi offers one of the most secure warranties on the market, ensuring first-year degradation below 1%. In the following years (2-30), the performance drop is only 0.4% annually, guaranteeing stable power production for decades. After a full 30 years of operation, the module retains as much as 87.4% of its initial power. Such durability makes it an ideal choice for investors who value the highest quality.
