QCells 400W

The Qcells 400W DUO BLK ML-G10+ bifacial module is a high-performance monocrystalline photovoltaic panel engineered for residential and light commercial installations requiring elevated power density and long-term reliability. Built with Qcells’ DUO half-cut cell architecture and advanced mono PERC technology, the module reduces internal resistive losses while improving shade tolerance and thermal performance under real-world operating conditions. The bifacial cell design enables additional energy generation from rear-side irradiance, increasing overall system yield in reflective environments such as light-colored roofing, ground-mount arrays, or elevated racking configurations. A robust anodized black aluminum frame and high-transmittance tempered glass provide structural durability against wind, snow, and environmental loading while maintaining consistent electrical characteristics across strings. Manufactured to stringent quality and bankability standards, the Qcells 400 W bifacial DUO BLK module offers a balanced combination of efficiency, durability, and bifacial energy gain, making it well-suited for projects prioritizing performance stability, aesthetics, and long-term production value.
