Impact of Different Weather Conditions on the Efficiency of Photovoltaic Systems

Given the significance of PV photovoltaic systems among other renewable energy sources, it is essential to model and simulate these systems before installation due to their high cost. Therefore, developing a model that can yield appropriate and accurate results from the system under study is crucial. The aim of this study is to evaluate how photovoltaic modules function across various climatic conditions. The conditions explored in this study include the impact of dust, changes in air mass, temperature, and wind speed. The simulation results in MATLAB / Simulink and laboratory experiments reveal that the performance of the model is greatly affected by dusty conditions, leading to a decrease in power generation due to reduced radiation reaching the module surface. An increase in air mass also results in decreased power output. Additionally, temperature fluctuations cause a reduction in power generation as the module surface temperature rises. Interestingly, changes in wind speed did not significantly impact the performance or output power of the PV module.
