Technical Specifications

Product Structure

This HNA-NEG19RC.20 Vertex Supreme N bifacial dual-glass solar module adopts a full double-glass laminated structure with N-type half-cut i-TOPCon Ultra cells as the core power generation unit.

The outermost layers are two pieces of 2.0mm high-transmittance tempered glass on both front and rear sides, which realize bidirectional light absorption and provide strong anti-corrosion and weather resistance. 132 half-cut cells are arranged inside, divided into three independent circuits with built-in bypass diodes to eliminate hot spot risks under partial shading. High-performance encapsulant film tightly seals the cells to block moisture and corrosive gas.

The whole laminate is framed by 30mm thick anodized aluminum alloy for structural support, improving mechanical load resistance against wind and snow. An IP68 waterproof junction box is mounted on the back, equipped with 4.0mm² PV cables and compatible TS4 & MC4 EVO2 connectors for convenient series-parallel connection. The overall compact structure balances light weight and durability, adapting to various complex outdoor installation environments.

How HNA Vertex Supreme N Bifacial Dual-Glass i-TOPCon Ultra Solar Module Works

This HNA-NEG19RC.20 bifacial dual-glass solar module takes N-type i-TOPCon Ultra half-cut cells as the core power-generating medium. The N-type passivation contact technology greatly reduces carrier recombination inside cells, lowering power loss and lifting photoelectric conversion efficiency up to 24.1%.

The dual-glass laminated structure realizes double-sided light absorption. The front 2.0mm high-transmittance glass absorbs direct sunlight, while the rear transparent glass captures albedo reflected from ground, water and crops to generate extra power. Designed with a three-circuit layout and built-in bypass diodes, the module restricts hot spot damage caused by partial shading.

With an ultra-low power temperature coefficient, it slows down power attenuation under high ambient temperature. Zero PID and ultra-low LID characteristics ensure stable power output under weak light such as cloudy days and twilight. The absorbed light energy is converted into direct current, which is exported via IP68 junction box and PV cables for power collection and conversion by inverters.
