BS EN 62925 defines a test sequence that will quickly uncover concentrator photovoltaic CPV module failures that have been associated with field exposure to thermal cycling for many years. BS EN 62925 was specifically developed to relate to thermal fatigue failure of the HCPV die-attach, however, it also applies, to some extent, to all thermal fatigue-related failure mechanisms for the assemblies submitted to test.
In IEC 62108, the CPV module qualification test already includes an accelerated thermal cycle sequence in one leg of the testing, however, the parameters of that test only represent a qualification level of exposure. Test procedure in BS EN 62925 applies more stress and will provide a route for comparative testing to differentiate concentrator photovoltaic modules.
BS EN 62925 on concentrator photovoltaic (CPV) modules is useful to:
Concentrator photovoltaics is a photovoltaic technology that uses sunlight to generate electricity. Unlike traditional photovoltaic systems, it focuses sunlight through lenses or curved mirrors onto small, extremely efficient multi-junction (MJ) solar cells.
BS EN 62925 provides a test method that will swiftly detecting concentrator photovoltaic module failures that have been connected with field exposure to thermal cycling for many years.
The best industry guidance in BS EN 62925 provides test evaluation of thermal fatigue failure over a long period of time. With this analysis, you can achieve the long service life and durability of concentrator photovoltaic modules
With exposure qualification level requirements in BS EN 62925, you can demonstrate reliability and improve the efficiency of concentrator photovoltaic modules.
