Öğe COOLING OF SOLAR PANELS USING CHANNELS(2023-07) Al-Mohammedawi, Mujtaba Jalal KhazaalSolar energy is an essential source in this era. One of the most important applications of solar energy is solar panels; however, the problem with solar panels is that the higher their temperature, the lower their efficiency. To address this issue, it is imperative to cool the solar panels using a simple and effective cooling system. Therefore, this research conducted an experiment to explore cooling methods by implementing fluid channels on the back of the solar panel. Water and air were used as cooling fluids, and different flow rates (0.35 L/M, 0.7 L/M, and 1.4 L/M) were tested for each case. Four models with varying numbers of channels (3, 5, 7, and 9) were employed in the study, and the theoretical analysis was performed using the Ansys 22 program. The results revealed that increasing the flow rate enhanced the cooling efficiency, with a flow rate of 1.4 L/M being the most efficient. Moreover, the cooling efficiency increased with the number of channels in the models, with the 9-channel model demonstrating the highest efficiency. As a result, this model dissipated less heat from the solar panel, leading to improved electrical efficiency. When comparing the cooling fluids, it became evident that water cooling outperformed air cooling, exhibiting superior results.
