Our company began to cooperate with T¨¹V Rheinland£¨Shanghai£©Group China to launch T¨¹V certificate on April 2009.
The TÜV Rheinland Group is a leading provider of technical services worldwide. The Group¡¯s mission and guiding principle is to achieve sustained development of safety and quality in order to meet the challenges arising from the interaction between man, technology and the environment.
The TÜV certificate for crystalline silicon solar panels including IEC 61215 and IEC 61730.
Qualified, IEC 61215 (IEC 61215 Crystalline Silicon Terrestrial Photovoltaic (PV) Modules - Design Qualification and Type Approval.)
The IEC 61215, respectively EN 61215, comprises the examination of all parameters which are responsible for the ageing of PV modules and describes the various qualification tests on the basis of the artificial load of the materials. In particular one differs between the following load groups:
Sunlight incl. UV
Climate (changing of climates, coldness, warmth, humidity)
Mechanical load (hail, wind suction, wind pressure, snow)
The tests are judged to be passed, if after the qualification tests no major visual defects are detected and the output power has not or only slightly degraded from its initial value.
The qualification certificate corresponding to IEC 61215 has gained acceptance in the past few years as the quality symbol for crystalline PV modules. Nowadays such a certificate is required for most national and international funding programs.
Safety tested, IEC 61730
Tests according to IEC 61730, Photovoltaic (PV) module safety qualification.
The standard IEC 61730 comprises the requirements for the design and the testing of PV modules regarding the qualification for the safe electrical and mechanical operation throughout their expected lifetime. The test sequences of the IEC 61730 are designed such that they can co-ordinate with those of the IEC 61215 / IEC 61646 (PV modules - design qualification and type approval) and the test samples may be used for the performance as well as for the safety qualification. Among the test categories are:
general inspection
electric shock hazard
mechanical stress
environmental stress
Besides the basic tests, the standard foresees additional tests that depend on the module end-use applications, which are categorized in classes A, B and C.
The tests are judged to be passed, if the test applied would not result into potential electric shock, fire and personal injury. |
