Trina Solar Vertex N modules are based on N-type cells in i-TOPCon technology, designed to maximize gains throughout the entire lifecycle of the installation. In practice, this means better performance at high temperatures and significantly more stable energy production over the long term – especially where predictability and low operational costs are key.

A major highlight is the dual-glass construction, which enhances resistance to moisture, temperature fluctuations, and micro-cracks. Combined with high bifaciality (in two-sided variants), the Vertex N series enables a truly significant gain when modules operate above a light-colored background or on elevated structures.

Vertex N is an excellent choice for utility-scale PV farms and commercial installations, where lower BOS costs, easier logistics, and compatibility with trackers are crucial. It stands out from the competition thanks to its refined platform for large-size cells and a focus on long-term reliability, rather than short-term paper gains.

About the simulation: Calculations based on declared annual degradation (-%/year). Default irradiance (1200 kWh/kWp/year) is an average - check your exact value using PVGIS. Actual production depends on location, orientation, shading, and installation quality.

Cell temperature of 75°C is typical for rooftop panels on a hot summer day at full irradiance. Temperature coefficient -0.290%/°C means power drops by this percentage for each degree above 25°C.

What is albedo? Albedo is the fraction of sunlight reflected by a surface. Higher albedo (lighter surfaces) means more light reaches the back of bifacial panels, increasing total energy production.

Calculation: Bifaciality (-) × Albedo × 0.6 (view factor)

This calculator uses a simplified model with default albedo values and a ground coverage factor of 0.6. Actual gain depends on installation conditions, tilt angle, mounting height, and season. For accurate calculations, we recommend measuring albedo on-site.
