LONGi EcoLife LR7-54HVB-470M (470 W, full black)

The LONGi EcoLife LR7-54HVB-470M is a modern 470 W photovoltaic module designed for demanding residential installations. It features high efficiency of 23.0%, an elegant pure black appearance, excellent mechanical durability, a 30-year product warranty, and a linear power warranty.

Practical benefits

• More energy from the same space: With 470 W power and 23.0% module efficiency, it delivers high energy yield even on limited roof space.
• Modern, uniform roof appearance: The design without visible grid lines and low reflectivity makes the panel visually appealing on residential buildings.
• Better performance in real conditions: The manufacturer provides anti-shading and hotspot mitigation features, improving module safety and performance under partial shading.
• Long lifespan and predictable output: Power degradation in the first year is less than 1%, and only 0.35% per year from years 2–30. After 30 years, the module retains 88.85% of its original output.
• High mechanical resistance: 3.2 mm tempered glass, front load resistance up to 5400 Pa, and hail resistance of 25 mm at 23 m/s ensure long-term safety.
