Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials. Other degrading mechanisms
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.
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 .
To reduce the degradation, it is imperative to know the degradation and failure phenomena. This review article has been prepared to present an overview of the state-of-the-art knowledge on the reliability of PV modules.
Critical degradation in PV modules was also highlighted as initiating fire in a research project based in Germany . Fire can also be caused by hotspot failure, primarily driven by other failure mechanisms that elevate the operating temperature to a hazardous level, and eventually cause a fire [42, 43].
The area affected by bubbles in the PV module operates at hotter temperatures and potentially leads to burn marks . A study by Rajput et al. analysed the degradation mechanism of 90 monocrystalline PV modules operated for 22 years in India; it was found that the PV modules affected by more bubbles had more power loss.
Solar panel degradation comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials.
