Vertex technology

The Vertex series panels are equipped with various design and technological features that allow ​high output power even in a limited space​ allowing 21.1% module efficiency with high density cell interconnection.

Trina solar on this type of multi-busbar modules has introduced a revolutionary technology  that integrates 1/3 cut  cell, non-destructive cutting and high-density interconnect technologies.

1/3 cut cell technology compared to traditional half cut technology solves problems related to the high system current and reduces power loss.

​Cell spacing has been reduced from to 0.5mm ​to 1, in order to optimize output power and efficiency, this solution reduces gaps and risks of micro-cracks and module damage over time.

This solution allows for greater power and power generation capacity.

Vertex S thanks to this new technology is able to offer up to 65W more than modules with the same size and conventional technology.

Compatible with major inverters and mounting systems

This range of modules has been designed for rooftop applications and is compatible with major inverters, optimizers and mounting systems Reduced size and weight make it easy to handle.

Reduced transport and installation costs thanks to the higher power and consequently the lower number of modules required.

Enhanced Warranty

The product has a 15-year guarantee, the maximum annual deterioration of the power is 0.55% from the 2nd year to the 25th year.
