Özet: In this study, experimental and numerical investigation of the performance of the conventional photovoltaic panel, concentrated photovoltaic (CPV) system and water-cooled CPV system were performed, where the practical study was implemented at Al-Kitab University - Kirkuk - Iraq on the effect of the climate (dust and high temperatures) on the output of the solar cell (efficiency - maximum energy and output). In the practical aspect, solar panels with similar specifications were used, one of the panels is clean and the other is dirty with dust, the same used dust that was collected from the roof of the building that was brought by storms. Four cases of dust weights were studied (later using dust layers and dealing with thickness) during the period from nine o'clock until 5:00 p.m. during July and August. The results showed that the temperature of the cell increased in direct proportion to the thickness of the deposited dust layer, which caused the cell power and output current to decrease compared with the clean cell. The energy was reduced by 60% when the dust layer was at the level (dust 4) and the output current lost about 0.6 amperes under the same conditions. The cell occupancy was simulated using practical data and synthesized in a Simulink-MATLAB environment. The agreement of the experimental results with the simulation results demonstrated the deterioration of the performance of the solar cell at different levels of cell temperatures due to dust deposited on it.
