Investigation of Some Key Factors Impacting Floating Photovoltaic Solar System Performance on Major Iraq Water Bodies

High population density, land exploitation, and water scarcity are the biggest problems in the world. To solve these problems, floating solar power plants were chosen because of the advantages of this system and high efficiency compared to land systems. In this study, the reservoirs of the five main dams in Iraq were chosen: Dukan, Darbandikhan, Hamrin, Haditha, and Mosul. They were covered with percentages of 5%, 10%, 25%, 50%, 75% and 100%. This study aimed to produce energy and meet the population's electricity needs and evaporation losses. The results revealed that covering the reservoirs by 100% can produce 230.53, 7526666, 15561, 244059, and 184692 MW from reservoirs of Dukan, Darbandikhan, Hemrin, Haditha, and Mosul dams respectively. Evaporation results show that covering dams by 100% can produce 14.12, 471.40, 16.34, 27.03, and 20.08 million cubic meters, the result revealed that covering the dam's reservoirs by 75% could reduce the evaporation rate by 15 times.
