Description of the product
Solar panel Trina Vertex S+ TSM-NEG9R.28 445W
This next-generation, high-efficiency monocrystalline PV module based on N-type i-TOPCon cells is designed for rooftop solar power systems for private homes, commercial properties, and small industrial systems.
This model is part of the Vertex S+ series from Trina Solar, one of the world’s leading PV module manufacturers. The panel combines high efficiency, compact dimensions, and increased durability thanks to its dual-glass design.
Unlike the bifacial models in this series, the TSM-NEG9R.28 is a monofacial module, meaning it generates power only from its front side. This makes it an optimal solution for traditional rooftop solar power systems, where bifacial generation typically does not provide significant additional efficiency.

Features and advantages:
The module delivers a rated power of 445 W and an efficiency of up to 22.3%, enabling greater energy yields with limited roof space.
N-type i-TOPCon Technology
The advanced solar cell architecture provides:
- low power degradation;
- more stable operation at high temperatures;
- increased durability compared to traditional P-type modules.
Dual Glass Design
The use of tempered glass on both sides increases the module’s resistance to:
- microcracks;
- moisture;
- ammonia and salt fog;
- temperature fluctuations.
This design provides better protection for the cells and stable operation over a long service life.
Multi-Busbar Technology
The multi-busbar conductor structure improves current collection, reduces resistance, and increases the module’s efficiency.
Optimal format for rooftop solar power systems
The module’s compact size allows for easy integration into standard mounting systems for residential and commercial buildings.
High mechanical strength
The module is designed to operate in challenging climates and withstand significant snow and wind loads.
