Description
The LONGi 640 Watt MF (Monofacial) Solar Panel is a high-efficiency photovoltaic module designed for residential, commercial, and utility-scale solar systems. Built using advanced N-type monocrystalline HPBC (Hybrid Passivated Back Contact) cell technology, it delivers excellent energy output, improved reliability, and better performance in low-light conditions. With a rated power of 640W and module efficiency reaching around 22–23%, this panel allows installers to generate more electricity using fewer modules, making it ideal for large solar installations.
The panel features a half-cut cell design that reduces internal resistance and minimizes power loss caused by shading, ensuring higher energy yield throughout the day. Its strong 3.2 mm tempered anti-reflective glass, anodized aluminum frame, and IP-rated junction box provide durability and protection against harsh weather conditions. The module can operate in temperatures ranging from −40°C to +85°C, making it suitable for different climates including hot regions.
With a 12–15 year product warranty and up to 30-year linear performance warranty, the LONGi 640W MF solar panel offers long-term stability and reliable electricity production. Its high power output, strong build quality, and advanced technology make it a popular choice for modern solar energy systems that require maximum efficiency and long service life.
