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 [26] 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. In this period, there was a much .
The environmental impacts of PV power generation system from the manufacturing stage (Fthenakis et al., 2005), to installation and operation (Turney and Fthenakis, 2011), decommission and disposal or recycling of solar PV equipment (Fthenakis et al., 2008) have been reported in the literature.
PV modules inspection revealed severe damage of junction box tubes, golden brownish discoloration, delamination of encapsulant with severe milky pattern, oxidation of front grid metal fingers, busbar and AR layer.
This paper conducts a state-of-the-art literature review to examine PV failures, their types, and their root causes based on the components of PV modules (from protective glass to junction box). It outlines the hazardous consequences arising from PV module failures and describes the potential damage they can bring to the PV system.

6 FAQs about [Investigation report on the cause of damage to photovoltaic panels]
Do we need to review PV failures and degradation?
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.
Can critical degradation in PV modules cause fire?
For instance, critical degradation in some PV modules in an array system leads to mismatch, increasing the PV module’s temperature and subsequently leading to fire [40, 41]. Critical degradation in PV modules was also highlighted as initiating fire in a research project based in Germany .
Why do PV modules have abnormal degradation rates?
For instance, the National Renewable Energy Laboratory (NREL) developed accelerated stress tests to examine degradation rates, validating the superior quality and long-term reliability of PV modules . However, despite these measures, there are still reports of abnormal degradation rates in PV modules due to a variety of failures.
What factors affect the performance of photovoltaic (PV) modules?
The degradation of photovoltaic (PV) modules due to various factors, such as dust, discoloration, delamination, hotspots, cracks, temperature, and humidity, can have a significant impact on their performance and lifespan. The following are some mitigation strategies to reduce the impact of these factors:
Does a crack in a PV panel affect output power degradation?
The possible impact of a crack and its position on output power degradation might significantly shorten the PV panel’s expected lifetime. The significance of a crack depends on the percentage of damage to a PV cell. This study found that 50% of damaged cells are cracked parallel to the busbar.
Is solar PV degradation a problem?
Utilizing solar PV to generate energy is not a simple operation due to degradation, which can result in a reduction in solar PV performance and efficiency [1, 2]. According to recent studies, the rate of degradation varies between 0.6% and 0.7% per year [3, 4].
