Trina 440W Vertex S+ N-Type DG (TSM-440NEG9R.28 (IEC 61215-2021))
The Trina Vertex S+ TSM-440NEG9R.28 is a 144-cell, N-type monocrystalline solar module with dual-glass construction. It delivers ~ 440 W peak power with high efficiency and is designed for durable, long-lasting performance — suitable for residential or commercial rooftop and ground-mounted solar installations.
- Product Code:23226
- Model No.:TSM-440NEG9R.28 (IEC 61215-2021)
- Delivery & return
High-density interconnect and N-Type i-TOPCon cells — Uses advanced N-type (i-TOPCon) monocrystalline cells, enabling high module efficiency (~22–22.5 %) and improved reliability (lower degradation, better low-light & temperature performance).
Dual-glass (glass–glass) construction for enhanced durability — The double-glass design improves mechanical strength, resistance to micro-cracks and back-sheet degradation, and ensures better longevity and environmental resistance (dust, humidity, heat, etc.).Reliable long-term performance and warranties — Backed by a 25-year product warranty and 30-year linear power warranty, combined with low degradation rates (about 1% first year, then ~0.4% per year), giving confidence in long-term energy yield.
Strong environmental & mechanical resilience — Designed to withstand mechanical stresses: rated for up to 5400 Pa positive load (e.g. snow/weight) and 4000 Pa negative/wind load, along with good resistance to environmental stressors — making it robust for varied climates including high heat and dust common in many areas.
