Trina Solar 670W Vertex Modules Show Remarkable Mechanical Performance At -40°C

Trina Solar’s Vertex modules receive Carbon Footprint Certificate, another plus for sustainable development

Trina Solar’s Vertex modules have passed another extreme weather test, this time demonstrating proven reliability and performance at -40°C.


Third-party organization China General Certification Centre (CGC) and Trina Solar
conducted the mechanical reliability test on the Vertex 670W module through
extreme low-temperature conditions of -40°C in accordance with the testing requirements of the International Electrotechnical Commission’s (IEC) TS 62782. The latter is the IEC’s standards for solar modules.

Testing at -40°C is important because Trina Solar’s modules are used worldwide in
various climates including extremely cold weather conditions, in places such as northeast China’s Heilongjiang province to Arctic Circle countries such as Sweden and Norway.
Extreme low temperature is a major challenge to materials, so it is fundamental for
Vertex modules to be highly reliable and generate high power efficiency under these
conditions. The coefficient of thermal expansion varies among different materials and poses challenges to connecting parts of modules.


The static mechanical load test of 5400Pa and 2400Pa, on the front and back of the
modules respectively, was completed under the extremely low temperature of -40°C
and crossbeam screw installation conditions. The mechanical strength, resistant ability of materials and connection of trackers under extremely low temperature were simulated to test the reliability and performance of PV modules.

The results show the modules remain visibly good in appearance without cracks, passing the test of insulation and wet leakage, with power attenuation of only 0.11%. This proves that even under extremely low-temperature conditions, Trina Solar’s 670W Vertex modules are of excellent quality, safe and reliable.

Earlier tests, prior to the -40°C temperature test, have already verified that the modules can withstand non-uniform snow-loads, perform well under extreme dynamic mechanical loads (DML) and strong winds. The 670W Vertex was launched in March based on large 210mm diameter silicon wafers. The modules release low-voltage and high power while achieving maximum power efficiency of 21.6%.

Trina Solar has been able to lay solid foundations in technology and forged products
with high efficiency and high reliability that feature the world’s best performance,
based on its R&D and manufacturing experience for the past 24 years. Regardless of
strong winds, snowstorms, or extreme cold; Trina Solar Vertex modules demonstrate
perfect performance. Trina Solar also offers customized services including product design and installation design for different application scenarios to provide total solutions for customers.
