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.
Photovoltaic failure is not defined uniformly in the literature. Some definitions indicate that a drop of 80% in maximum output power is considered a PV failure . Others claim a 20% drop in maximal power is a PV failure . Durand and Bowling defined failure as a drop of more than 50% in maximum power output.
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.
The need to review PV failures and degradation has encouraged researchers to engage in comprehensive research investigating and analysing experiments and real-world industry studies available in the literature. Köntges et al. reviewed PV failures based on their emergence in the operational life cycle.
