Product Description

Vertex TSM-DEG19RC.20 Bifacial Dual Glass Monocrystalline Solar Module

The Trina Solar Vertex TSM-DEG19RC.20 555-575W Double Glass Solar Panel is a high-performance bifacial monocrystalline photovoltaic module designed for utility-scale solar farms, commercial rooftop systems, and large-scale renewable energy projects. Featuring advanced 210mm silicon wafer technology, high-density interconnection technology, and multi-busbar (MBB) cell design, this Vertex series module delivers up to 575W maximum power output and 21.3% module efficiency for improved energy generation and lower system costs.

Built with a dual glass structure, the module uses a 2.0mm heat-strengthened front glass and 2.0mm rear glass, providing excellent durability, enhanced mechanical strength, and superior resistance against harsh environmental conditions. The bifacial design allows the rear side to capture additional solar radiation, generating up to 25% additional power gain depending on albedo conditions, increasing overall energy yield throughout the system lifetime.

The Trina Solar Vertex DEG19RC.20 series adopts 132 half-cut monocrystalline cells and optimized electrical design to reduce resistive losses, improve current collection efficiency, and maintain stable performance under high temperature, low irradiance, and complex outdoor environments. With a robust dual-glass construction, PID resistance, and 30-year linear power warranty, this module provides long-term reliability for demanding photovoltaic applications.
