This means that, compared to the omitted base group, which is the moderate climate zone, the annual degradation was, on average, 0.642 %pt. Higher for modules located in desert climates. These results are consistent with expectations, as elevated temperature and humidity are known causes of defects in PV modules .
modes in these older generation G/G modules. Delamination appear ed to originate near edges of a with EVA. Glass breakage likely develop ed at scratches or chips on glass surfaces and edges. of thinner glass sheets that are more susceptible to glass breakage . appearance of various degradation modes . The field ages vary between 1-25 years,
The effect of encapsulant delamination is prominent in glass/glass modules due to the impermeable nature of glass compared to polymerbased backsheet material as shown in Fig. 13. The degradation products get trapped between interfacial layers promoting their delamination [32, 40].
Some recent studies suggested that glass defects were more prominent in newer modules (less than 4 years of age) as compared to 20 year old modules, which may be attributed to the adoption of thinner glass sheets that are more susceptible to glass breakage . Figure 6.
