Show series description

The HY SOLAR N-Type TOPCon series (available in various configurations and frame options) is designed for real-world operating conditions, where stable performance, predictability, and energy loss resistance are paramount. A key advantage is the use of N-Type TOPCon cell technology, which supports high efficiency over the long term and helps to minimize performance degradation typical of older solutions. Many variants feature a bifacial design, allowing the module to also utilize reflected light from the ground, which improves energy production in PV farms, ground-mounted systems, and PV+ projects.

The use of SMBB and half-cut cell technology also enhances current flow within the module and improves performance under partial shading. The manufacturer also highlights improved performance in low-light conditions and the beneficial impact of a lower temperature coefficient on energy yield in hot weather. This series is ideal for investors who want to combine high power density with practical reliability in commercial and industrial projects.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
