Skip to content The NASCCLamp NAS-MB Series is a high-power N-type bifacial double-glass photovoltaic module, available from 580W to 605W. Built with 132 half-cut monocrystalline cells, this panel delivers up to 23.4% conversion efficiency and features a bifacial factor of 80%±5%, enabling significant rear-side power gain from reflected light. The double-glass (2.0mm front + 2.0mm back) construction provides exceptional durability against harsh weather conditions, while the IP68 junction box ensures long-term reliability. Designed for utility-scale ground mounts, commercial rooftops, and high-reliability off-grid systems across Southeast Asia, Africa, South America, and the Middle East.
