What is a thermal cycling test?
Thermal cycling test is definite requiremented in several test standards, including IEC61215 (Crystalline silicon photovoltaic modules for terrestrial use-design qualification and finalization), IEC61646 (Thin film solar module test standard), IEC62688 (Concentrator CPV modules and components-safety certification) and IEC62108 test standard.
How many times a thermal cycle test does a module need?
In the 200 thermal cycle test, connect the module with the maximum power point current under standard test conditions ±2%, only when the component temperature problem exceed 25℃ keep the flow of electric current, 50 times thermal cycling test does not require through current.
How do temperature changes affect photovoltaic modules?
Photovoltaic (PV) modules in the field are exposed to temperature changes. Day and night, as well as seasonal changes determine module temperatures.
How El test is performed in a PV module?
For investigation and spatial analysis of cell defect and finger breakages in PV modules, EL test is performed in a camera (D810S, Nikon, Japan) controlled by a monitoring personal computer when the module is biased by an externally programmed supply (TDK-Lambda, GEN150-10). 2.6. Resistance (R s) determination
Does thermal load affect strain energy density of a PV module?
In the model an aggressive thermal load cycle is simulated and its effect on the strain energy density of a PV module is examined. The thermal load during an operating cycle of 4.5 h is prescribed as a temperature which varies between −40 °C and 85 °C, and the initial temperature is the room temperature of 25 °C.
How long does it take a PV module to degrade?
Standard IEC 61215 temperature cycling (TC) tests emulate this ageing typically requiring 30 to 50 days for 200 thermal cycles (degradation < 5 % is the IEC pass criterion). A faster assessment of PV modules is de-sirable to rapidly evaluate new interconnection technologies and module concepts.
