Trina Solar Vertex N-Type i-TOPCon Bifacial Dual Glass Monocrystalline Module (TSM-NEG19RC.20 625–650W)
Description
The Trina Solar Vertex N-Type i-TOPCon Bifacial Dual Glass Monocrystalline Module (TSM-NEG19RC.20) is a high-efficiency photovoltaic module designed for utility-scale, commercial, and residential solar energy systems. Built using advanced N-type i-TOPCon (Tunnel Oxide Passivated Contact) cell technology and a bifacial dual-glass architecture, the module delivers superior power generation, long-term reliability, and enhanced energy yield under various environmental conditions.
The module provides a maximum power output of 650 W with a peak conversion efficiency of 24.1%, making it one of the highest-performance modules in its class. Its bifacial design allows the rear side of the panel to capture reflected sunlight (albedo), increasing overall energy production by approximately 10–20%, depending on installation conditions and ground reflectivity.
Designed with 132 half-cut monocrystalline cells, the module minimizes resistive losses, reduces hot spot formation, and improves performance under partial shading. The dual-glass construction enhances durability by providing excellent resistance against moisture, corrosion, UV exposure, mechanical stress, and harsh environmental conditions, making the module suitable for long-term outdoor installations.
The module incorporates Trina Solar's patented i-TOPCon technology, which reduces contact resistance, improves rear-side reflection, minimizes carrier recombination losses, and continuously increases cell conversion efficiency. Innovative non-destructive cell cutting technology further reduces micro-cracks while maintaining excellent structural integrity and long-term performance.
The panel is certified to operate under extreme environmental conditions, including resistance to salt mist, ammonia, sand abrasion, Potential Induced Degradation (PID), Light Induced Degradation (LID), and Light and Elevated Temperature Induced Degradation (LeTID), ensuring stable performance throughout its service life.

Application in SolarScope
Within SolarScope, the Trina Solar Vertex N-Type i-TOPCon 650 W module can be included in the Solar Panel Library Module as a predefined photovoltaic component. Each panel record should store its electrical, mechanical, and performance parameters—including dimensions, rated power, efficiency, temperature coefficients, bifacial gain, weight, and manufacturer information—so the system can accurately calculate panel placement, roof coverage, installed capacity, energy generation, shading effects, and overall system performance. This enables engineers to select real-world panel models during the design process while ensuring that simulations and analytical results closely match actual installation conditions.
