The Trina Solar TSM-620NEG19RC.20 is a high-performance 620 W photovoltaic module from the Vertex N series, manufactured by Trina Solar, one of the world’s leading solar module producers.

The module features advanced n-type i-TOPCon cell technology, delivering higher efficiency, lower degradation, and improved performance under low-light conditions. Its bifacial design enables additional energy generation from the rear side—up to 10–30% extra yield depending on installation conditions.

The glass-glass construction enhances durability and resistance to environmental conditions. With high efficiency (~23%) and large module power, it is ideal for commercial and utility-scale installations.
