Trina Solar Vertex S+ TSM-445NEG9R.28 Solar Module 445 Watt Black Frame n-type TOPCon Glass-Glass 25 Years Product Warranty

The Trina Solar TSM-445NEG9R.28 Vertex S+ is a dual-glass solar module with n-Type i-TOPCon monocrystalline cells, delivering 445 Wp at a module efficiency of 22.3%. Compact and lightweight at 1762 × 1134 × 30 mm and 21.0 kg, it supports 1500 V DC system voltage, withstands mechanical loads of 5400 Pa snow and 4000 Pa wind, and offers a long-term warranty of 25 years product and 30 years linear power (≤1% first-year degradation, ≤0.4% annually, ~87.4% at year 30).

 • High power density — 445 Wp: reduces BOS costs with more energy per module.
• n-Type i-TOPCon cells: lower LID/LeTID, better low-light response and long-term reliability.
• Dual-glass design: enhanced fire safety, higher resistance to moisture and mechanical stress.
• Strong efficiency — ~22.3%: optimized space usage, ideal for rooftops with limited area.
• Robust mechanics: certified for 5400 Pa snow and 4000 Pa wind loads.
