Trina Solar Vertex line 210 mm cell modules

A historic Chinese integrated company in the photovoltaic sector, active since 1997, has always been at the forefront thanks to a strong research and development team.

In the constant search to lower LCOE (levelized cost of energy), Trina Solar has recently introduced the modules of the Vertex serie to the market.

Reinforced frame, multi-busbar technology and high-density encapsulation

These new modules, are the state of the art of photovoltaic modules: They enclose in a further reinforced frame all the new emerging technologies: 210 mm cells cut to 1/3 with efficiency that reaches over 21%, multi-busbar technology and high-density encapsulation, also in the double-sided version.

210mm silicon wafer

The 210 mm silicon wafers, is the largest size currently possible, the choice of the 1/3 cut means that the current supplied is compatible with the majority of current inverters on the market, even in the residential segment.

The further improved temperature coefficient guarantees higher energy productions even in hot climates. The cutting of the cells takes place with a new low temperature method called NDC (non-destructive cutting) which let the half-cell much  to be more performing in terms of mechanical resistance by improving the resistance to microcracks.

Round multi-busbars

The collection of current on the cell through the round multi-busbars increases efficiency by almost half a percentage point, perfect for large cells.

High-density encapsulation

High-density encapsulation is the right compromise between the normal distance between the cells and their overlap, in this way the user can get  greater efficiency and less microcrak

All these improvements can be found in the Vertex line in different formats so as to be able to embrace all market segments, residential, commercial roof and utility scale.


Trina Solar Vertex S TSM-DE09.08 – mono PERC – 120 half cells – 395/400 Wp

Vertex S TSM-DE09.08 is a monocrystalline module of small size and low weight, suitable for all kinds of installations.

  • 120 PERC half cut cells + multi busbar
  • Temperature coefficient of power: -0.34%/°C
  • Warranties: 15 years product, 25 years linear power
  • Size available: 395/400 Wp

Excellent performance

Thanks to multi-busbar technology and monocrystalline PERC half cells, Vertex S TSM-DE09.08 is able to guarantee excellent levels in terms of performance.

A further element that determines the higher yield of Vertex S modules is the NDC system, which is an unconventional construction method that allows cells to be cut without compromising their efficiency.

Another important value is the temperature coefficient for the maximum power, equal to -0.34%/°C: these panels are therefore able to maintain high power even under non-optimal temperature conditions.

Universal solution

Vertex S TSM-DE09.08 is designed to be compatible with the most common inverters and optimizers. The size and weight of the module make it easy to transport and install, suitable for different applications.

High resistance

Thanks to its robust structure, the TSM-DE09.08 can support up to 6000 Pa of snow load and 4000 Pa of wind load.


The linear power warranty offered by Trina Solar,  guarantees a degradation of 2% in the first year and <0.6% in the other years.
