Material interactions More often, material interactions with the encapsulant are a root cause for PV module degradation.
Subsequently the primary stress factors that affect module degradation were summarised; this includes irradiance, temperature, moisture, mechanical stress, soiling and chemicals. Finally, common degradation and failure modes were identified that occur generically in photovoltaic technologies were reviewed.
They found that the most common causes of early failure are junction box failure, glass breakage, defective cell interconnect, loose frame, and delamination. A study by DeGraaff on PV modules that had been in the field for at least 8 years estimated that around 2% of PV modules failed after 11–12 years.
The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
