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.
Some naturally occurring, or industrially produced, chemical species can cause corrosion of PV modules. The most common are salt mist in offshore areas (especially harmful in tropical climates), ammonia in agricultural rural areas, and sulfuric and nitric acid in industrial areas.
Here, the present paper focuses on module failures, fire risks associated with PV modules, failure detection/measurements, and computer/machine vision or artificial intelligence (AI) based failure detection in PV modules; and can serve as a one-stop source for PV system inspectors.
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.
As the photovoltaic (PV) industry continues to evolve, advancements in Investigation on the cause of damage to photovoltaic panels have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Investigation on the cause of damage to photovoltaic panels]
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:
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.
What causes a PV panel to deteriorate?
As manufacturer suggestions, a panel is degraded when its power reaches below 80% of its initial power. 110 Several factors such as temperature, humidity, irradiation, mechanical shock are responsible for the deterioration of PV panels. 110, 111 Table 4 presents different reasons for panel degradation.
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.
Why do PV modules deteriorate after installation?
It happens only few years after system installation and gradually degrades the performance of PV module. This degradation shows exponential growth. This occurs due to presence of stray currents in ungrounded PV systems . The modules with negative voltage or positive voltage to ground are exposed to this degradation.
What causes PV failures and degradation?
It is worth noting that most of the studies included in this review primarily focus on detailing failures and degradation observed in PV operations, which can be attributed to various factors, including the manufacturing process and other external influences.
