6 FAQs about [Dynamic and static standards for photovoltaic cell testing]
How do dynamic load tests affect accelerated ageing of PV modules?
With reference to accelerated ageing procedures of PV modules, dynamic load tests clearly reveal a different stress potential from that indicated by static mechanical loads. Consequently, fatigue mechanisms for soldered joints or for the cells themselves can be completely determined.
What are the performance PV standards?
The performance PV standards described in this article, namely IEC 61215 (Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design qualification of a PV module.
Do dynamic load tests reveal a different stress potential?
“Dynamic load tests clearly reveal a different stress potential from that indicated by static mechanical loads.” With reference to accelerated ageing procedures of PV modules, dynamic load tests clearly reveal a different stress potential from that indicated by static mechanical loads.
What is cyclic (dynamic) mechanical load test?
In which case, the cyclic (dynamic) mechanical load test can be applied to the flexible module in its rigid mounting system. This test has been written as a standalone technical specification, but it is likely to be used in conjunction with other test standards.
How do you test a PV module?
During the test, the PV module's reference plane, defined by the mechanical contact points to the horizontal base plane, must be kept. It is done by fixing the module to the mechanical frame structure to avoid angular effects (Fig. 4).
How does photovoltaic deviation affect the testing procedure?
Such deviation affects the testing procedure. Deviation of photovoltaic devices on vehicles is sometimes called “strange behaviors.” We may need a general computation method for general curved surfaces and non-uniform shading (aperture) environments. Accurate modeling will be required to be developed to understand that strange behavior.
