There is a growing interest in solar electricity generation in many countries worldwide. This trend is the recent installation of photovoltaic panels rather than solar power plants. However, the conversion efficiency of photovoltaic (PV) panels in solar electricity generation is declining due to the accumulation of dust and surface contamination. Furthermore, the process of cleaning photovoltaic (PV) panels situated on the roofs of residential and commercial buildings is a challenging and potentially hazardous task. In this study, the SELFCLEAN PV hydrophilic nano coating was applied to a single photovoltaic panel on a solar energy conversion system at Trakya University Faculty of Engineering, with consideration given to the roof slopes of buildings in Edirne province. During the summer season, when solar radiation is its highest, continuous data was collected over four months. Upon analysis of the results with this application, it was observed that there was an 8.14% increase in energy production in June, a 7.73% increase in July, a 6.34% increase in August, and a 5.34% increase in September, in comparison to the standard PV panel. Furthermore, cleaning PV panels over four months offers labor and cost advantages. Furthermore, water use is not required, significantly contributing to sustainability.

With the increase of photovoltaic (PV) penetration in the power grid, the reliability and longevity of PV modules are important for improving their payback period and reducing recycling needs. Although the performance of PV systems has been optimized to achieve a multi-fold increase in their electricity generation compared to ten years ago, improvements in lifespan have received less attention. Appropriate operation and maintenance measures are required to mitigate their aging. PV cells and modules are subject to various degradation mechanisms, which impact their long-term performance and reliability. Understanding these degradation processes is crucial for improving the lifetime and sustainability of solar energy systems. In this context, this review summarizes the current knowledge on key degradation mechanisms (intrinsic, extrinsic, and specific) affecting PV modules, as well as on-site and remote sensing methods for detecting PV module defects and the mitigation strategies employed for enhancing their operational lifetime under different climatic conditions in the global environment.
