Trina Solar PV Evolution Labs quality

Trina Solar, a world leader in the integrated manufacturing of photovoltaic solutions, was once again ranked “Top Performer” this year for the seventh consecutive year in the report recently published by PV Evolution Labs (PVEL).

PVEL is one of the leading independent photovoltaic module testing laboratories, and this is the seventh consecutive year that Trina Solar has been awarded this important award.

Tests and rigorous inspections in Trina Solar’s manufacturing facilities

To award this recognition, PVEL carried out rigorous inspections in Trina Solar’s production plants and analyzed the photovoltaic modules with tests on thermal cycles, PID degradation, mechanical load, as well as other product tests.

In addition, other factors were also evaluated such as the availability of .PAN files for designers.

Tested also Vertex Series

The new modules with 210 mm cells of the Vertex line were also included in these tests, confirming that the experience of over twenty years of research leads to products of extreme quality that lead to greater energy production and therefore a lower LCOE, point fundamental that all customers want to have from their investment in green energy production.


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.
