Special Issue Information

Dear Colleagues,

PV power plants of hundreds of MWp became the new standard in recent years, placing solar PV as the first-choice renewable energy to face global climatic change in the coming decades. This brings new challenges regarding the project, execution and maintenance of millions of PV modules distributed in a vast area. With the progress of PV technology and the reduced power tolerance, expected energy production faces depreciated external factors: irregular terrains, which may enlarge the mismatch losses due to the misalignment of the modules, areas more prone to soiling due to the local wind patterns and wind variations, which may induce thermal stress in the PV modules, affecting the lifespan of the PV plant. These are some examples that may affect the costs of new projects regarding the initial inversion and lifespan of a PV power plant, as well as the maintenance logistic in the PV plant or floating solar. For this Special Issue, our team invites you to collaborate with your original research related to PV generators. A broad range of topics related and relevant to PV generators are also welcome, as well as novel applications related to harnessing solar energy, like space-based solar power. We also encourage you to submit your research in related areas: meteorological analysis, experimental data, theoretical analysis and all relevant applications that may increase the current knowledge regarding PV generation.

Photovoltaic (PV) systems are widely adopted for renewable energy generation, but their performance is influenced by complex interactions between longer-term trends and seasonal variations. This study aims to remove these factors and provide valuable insights for optimising PV system operation. We employ comprehensive datasets of measured PV system performance over five years, focusing on identifying the distinct contributions of longer-term trends and seasonal effects. To achieve this, we develop a novel analytical framework that combines time series and statistical analytical techniques. By applying this framework to the extensive performance data, we successfully break down the overall PV system output into its constituent components, allowing us to find out the impact of the system degradation, maintenance, and weather variations from the inherent seasonal patterns. Our results reveal significant trends in PV system performance, indicating the need for proactive maintenance strategies to mitigate degradation effects. Moreover, we quantify the impact of changing weather patterns and provide recommendations for optimising the system’s efficiency based on seasonally varying conditions. Hence, this study not only advances our understanding of the intricate variations within PV system performance but also provides practical guidance for enhancing the sustainability and effectiveness of solar energy utilisation in both residential and commercial settings.
