Abstract: Water distillation and provision of drinking water takes a high percentage of electricity generated in many countries of the world. Solar distillation benefits from the sun's free energy in purifying salty or contaminated water and making it drinkable. In this study, a single distillation was produced and a distillate production was studied in the Spring of Baghdad-Iraq in 2017. A fan used to cool the glass cover was used at 12 noon. In other experiments, the lid was sprayed with water to cool. The results showed that the cooling of the glass cover in both methods caused the distillation of the distillate yield, but in the case of water, the improvement was greater.
