Trina Solar VertexN TSM-NEG20C.20 655W N-Type i-TOPCon Solar Bifacial Bual Glass Monocrystalline Solar Panel

The Vertex N TSM-NEG20C.20 embodies the latest innovations in photovoltaic technology, focusing on power, durability, and long-term value.

• N-Type TOPCon Cell Technology: At its core, this module uses n-type TOPCon cells, which provide higher bifaciality, lower light-induced degradation (LID), and a better temperature coefficient compared to traditional p-type PERC cells. This results in more energy generation over the panel's lifespan.

• Ultra-High 655W Power Output: Leveraging 210mm large-format silicon wafers and refined cell interconnection technology, it achieves an impressive power output of up to 655W. This high wattage reduces the number of panels, brackets, and cables needed for a project, significantly lowering balance-of-system (BOS) costs.

• Enhanced Durability with Dual Glass: The frameless double-glass construction (2x glass layers) offers superior protection against environmental stresses such as humidity, PID (Potential Induced Degradation), and abrasion. This design significantly extends the product's mechanical lifespan and provides a superior 30-year linear power warranty.

• Superior Bifacial Performance: The n-type cells enable a high bifaciality factor, allowing the module to generate additional energy from light reflected onto its rear side. This is particularly beneficial when installed over reflective surfaces like white gravel or ground-mounted systems with optimized tracking.

• Optimized for System Economics: The combination of high efficiency, low degradation, and reduced BOS costs directly contributes to a lower Levelized Cost of Energy (LCOE), ensuring a faster payback period and a higher return on investment for large-scale solar installations.
