Solar energy powering up aerial misting systems for cooling surroundings in Saudi Arabia

We demonstrated for the first time to our knowledge a misting system that is powered by solar energy. The system was used to cool down an open area in Medina, Saudi Arabia. The ambient and surrounding temperatures were measured and compared for different timing signals that were applied to the misting system. The used solar panel performance is evaluated for different loads, and tilting settings. The return on investment for the misting system is found to be about two years and half.

► Demonstrate solar energy misting system for the first time to our knowledge. ► Return on investment for such a system is recovered within two and half years. ► Solar panel tilt position is 25° due south in Medina Munawarah. ► The misting system is capable of lowering ambient temperature over 10 °C.
