Description
The Trina Solar Vertex N 720W Bifacial (NEG21C.20) sets a new standard in high-performance solar modules. Engineered with N-type i-TOPCon cells, this module delivers exceptional front-side conversion efficiency—up to 23.2%—while capturing additional energy from the rear side for up to 10–20% higher total output.
Its large-format 210 mm cell platform features half-cut, non-destructive cutting technology, minimizing micro-cracks and hot-spot risks. The dual-glass construction ensures top-tier protection against moisture, temperature fluctuations, and inclement weather, making it ideal for both utility-scale installations and commercial rooftops.
