Trina Solar Co., Ltd. ("Trina Solar" or the "Company"), a leading global PV and 
smart energy total solution provider, announced recently that the Vertex 600W 
and 550W series of glass-backsheet and dual-glass modules passed the TÜV 
Rheinland Photovoltaic Module IEC standard serial test and obtained two 
certificates, IEC 61215 and IEC 61730. The Vertex series became the first 600W+ 
high-power PV module that achieved IEC certifications in the PV industry.

Trina Solar's Vertex modules (600W & 550W), using 210mm size cells, have the 
characteristics of high power, high efficiency and high reliability, suitable 
for large-scale ground mounted PV power plants and large industrial and 
commercial rooftop projects. Besides Trina Solar's leading PERC and 
multi-busbar technology, it also adopts a low-voltage and high-string power 
design to increase the power of single-string of modules by more than 40%. At 
the same time, it integrates non-destructive cell cutting, high-density cell 
interconnection., The modules with dual glass structure also meet the highest 
fire protection rating of Class A of the IEC 61730 standard, enhancing 
operational safety and long term reliability.

The short-circuit current (Isc) and maximum output power (Pmax) of the 600W and 
550W modules have increased by more than 10% compared to last generation. 
According to the IEC 62915 photovoltaic module retest guidelines, various types 
of laboratory approvals and safety tests are required. The design-related 
qualification and type approval is done by applying temperature cycling 
(TC200), hot spot (HS) and diode heating and function (BD) tests. With high 
string power feature, the module Isc is accordingly higher, increased test 
current shall be applied during these tests, which brings usually some 
challenges on the module design and materials. However, Vertex's better 
reliability and optimized design are deployed to meet more severe challenges 
and passed this stringent test. At the same time, due to the larger cell size 
and ultra-high- module current, the supporting junction box also has to be 
upgraded according to the IEC62790 standard.

Mr. Zou Chicheng, Vice President of Solar Services at TÜV Rheinland Greater 
China, said: "600W+ ultra-high-power modules are an important direction for the 
development of the photovoltaic industry. As members of the 600W+ Photovoltaic 
Open Innovation Ecological Alliance, Trina Solar and TÜV Rheinland play key 
roles to their respective advantages to help and promote the development of 
600W+ ultra-high-power modules. From the beginning of the research and 
development stage of the Trina Vertex series modules, TÜV Rheinland has 
participated in the discussion and shared its own experience in product safety 
and reliability. Ultra-high-power modules mean that the current is further 
increased. To eliminate the impact of high current is a huge challenge for 
manufacturers, and it also puts forward higher requirements for the 
capabilities of third-party certification agencies. Trina Solar's Vertex 600W+ 
modules have passed TÜV Rheinland's comprehensive rigorous test and 
successfully passed IEC certifications, becoming the industry's first 600W PV 
module certified by a third-party organization. Hence it is fully demonstrating 
Trina's years of accumulated R&D and strength in supporting the industrial 
chain, and embodies Trina's consistent philosophy that "quality is a habit".

Dr. Zhang Yingbin, Head of Product Strategy and Marketing Department of Trina 
Solar, said: "The Vertex ultra-high power module is based on the brand new 
210/M12 cell technology, combining Trina's more than 20 years of technological 
experience and innovation, excellent R&D team and first-class domestic 
intelligent manufacturing base. This combination makes the Vertex series 
modules quickly become the new benchmark in the industry. At the same time of 
technological innovation, Trina Solar has been cooperating with third-party 
organizations to jointly explore the testing methods and evaluation standards 
for the long-term reliability of modules. Reaching the TÜV Rheinland 
reliability certification is an authoritative third party recognition of the 
high reliability of the Vertex module again.  It is an important part of Trina 
Solar's definition of the new high reliability warranty scheme for the Vertex 
series modules. We are convinced that this module with higher efficiency, 
higher power and higher reliability will bring a higher return of investment to 
customers".
