Evaporation is a process that changes fluid from liquid to gas. Evaporation rates from free surfaces depend on factors such as temperature, wind speed, water depth and vapor pressure. A detailed study of the information received from the Meteorological Office of Zahak concluded that the factors of temperature and wind speed in this region were the most influential factors, and interestingly, the main factor was the high wind speed. There are several methods to deal with the phenomenon of evaporation, which include the use of physical covering and wind speed. According to previous research, the best attraction of sunlight is to produce the highest Efficiency power in the northern hemisphere to the south. The use of solar panels is considered simultaneously as a physical covering to reducing evaporation and high-energy production. In this paper, priority is given to reducing evaporation and energy production equally. The use of modeling the flow rate effected by horizontal and vertical positioning angles of solar panels was used to obtain the best evaporation reduction using the ANSYS FLUENT 16 model and determining the best horizontal and vertical angle for obtaining the best output efficiency power. The results shows that in this case of designing solar panels measuring 2.5 × 2.5 meters by the angles of, the horizontal angle of 0° (Northwest towards the wind direction) and the angle of inclination of 60° with the evaporative reduction of 90.25 Percentage will be achieved. Also, the highest energy efficiency is achieved under the horizontal angle of 30 degrees (northwest towards the wind direction) and the angle of inclination is 30 degrees to 99.45 percent. Therefore, according to the available data, the optimal possible condition is the horizontal angle of 30 degrees (northwest direction, wind direction) and the angle of inclination of 30 degrees, with a reduction of evaporation of 71.36 percent and energy efficiency of 99.45 percent, Relative to the ideal state.
