An Overview of Dust Deposition Effect on Photovoltaic Performance in the Built Environment
摘要
Solar photovoltaic (PV) technology is a game changer in producing future energy, considering the relentless endeavors to mitigate and adapt to the effects of climate change under the Paris Agreement and the global commitment to the sustainable development goals (SDGs) established by the United Nations General Assembly. The vulnerability of PV systems is that they are weather-dependent, which means that extreme climatic conditions would significantly affect the reliability of this green technology. Dust existence is a critical matter directly manipulating the sustainability of PV projects in semi-arid and desert environments, which characterizes the Gulf Council Countries (GCC), raising the awareness of the relevant scientific community to the necessity of conducting more research to improve the performance of the PV modules facing this specific environmental hurdle. Thus, the quick literature overview here concerns narrating and simultaneously analyzing the content dedicated to studying the dust deposition effects on the PV characteristics in the global built environment—an attempt to transfer the lessons learned from others' experiences. Accordingly, the significant findings were that the dust deposition density is the primary influencer of power loss, while summer and low tilt angles are responsible for considerable energy drops in the presence of dust. Also, the numerical simulation studies revealed that the dust deposition rate increases with particle size but ultimately decreases. Finally, while the relevant research does not propose a prominent dust mitigation strategy other than regular manual cleaning, it is noteworthy that the issue was not addressed in green building rating systems.
