Trina Solar Vertex N Series N-Type i-TOPCon Bifacial Dual Glass Modules (TSM-NEG2) Engineering the Next Standard for High-Performance, Bankable Solar Assets 1. Introduction: From Nameplate Power to Long-Term Energy Value As the global photovoltaic (PV) industry matures, project success is no longer defined by headline wattage alone. Developers, investors, and grid operators increasingly prioritize lifetime energy yield, degradation control, bankability, and levelized cost of energy (LCOE). In this new landscape, advanced cell technologies and system-level optimization have become decisive factors. Trina Solar’s Vertex N Series, built on N-Type i-TOPCon bifacial dual-glass architecture, represents a decisive step toward this next phase of solar development. Rather than focusing solely on peak output, Vertex N modules are engineered to deliver stable, predictable, and superior energy production over 30 years, making them ideally suited for utility-scale, commercial, and industrial (C&I) solar projects worldwide.
