摘要

Photovoltaic cells are a promising solution for solar energy production due to their ease of maintenance and low fuel consumption. However, continuous exposure to sunlight causes them to overheat, reducing energy generation efficiency. Temperature control is essential for improving the performance of these systems. In this study, tests were conducted at a research laboratory in Adrar, Algeria, on two photovoltaic panels: one monocrystalline with a capacity of 200 W and the other polycrystalline with a capacity of 270 W. The results showed an increase in the panels’ efficiency by 9.4% and 9.9% when sprayed with a single dose of cold water at 10 °C for 10 min. These results highlight the importance of controlling the panels’ temperature to improve their performance and efficiency. The focus is on using cold water spray technology as an effective tool for improving the performance of solar systems in the future.
