Fossil fuel consumption problems and water crisis are serious dangers. Using renewable energy is a solution to reduce fossil fuel consumption. Photovoltaic is a renewable energy generation method which is abundantly used all over the world. By installation of solar panels on the surface of water, the efficiency of panels increases and in addition, the surface evaporation of water will be reduced. Dams are one of the main sources of water. In the present study, installation of solar panel on surface of the Tanguie dam is studied from technical point of view. The generation PV power is used to produce hydrogen by electrolysis process and consume it in PEM Fuel cell to decreases the peak load. Results show 2.6% increase in panel efficiency when they are installed on water. And this increase in efficiency causes that 360780 installed panels generate 4 million kWh additional electricity power in the year. As well as, covering 678628 m2 of dam with these panels prevent from 1.97 million m3 water evaporation in the year. Also, the generated PV power could supply about 99% of load which is above 90MW.
