Energy Yield Loss Caused by Dust and Pollutants Deposition on Concentrated Solar Power Plantsin Iraq Weathers

Concentrated solar power plants are promising applications in the field of renewable energy as their fuel is available and free of charge, namely, solar energy. Like any solar application, the first enemy is dust, which causes a kind of shadow that reduces the amount of solar radiation reaching the system, and its accumulation on the surface of the parts of the solar system reduces its performance. In this study, a miniature model of a concentrated solar plant was constructed and examined for several cases, the most important of which is when it is left to accumulate dust and dirt. In the second part of the study, the effect of the type of detergent used to restore the efficiency losses was studied due to accumulation of dust and contaminants. The results of the study showed that leaving the system exposed to external conditions for two weeks, caused losses of 22% of its efficiency. Cleaning the system returned 14.5, 17.39, and 19% of the efficiency losses when using water, alcohol, sodium cleaner, respectively.
