    Efficiency enhancement of solar panel with automatic water cooling system
    (UMT Lahore, 2018-06) Hafiz Usama Maood; Fahad Arif; Umar Qayyum
    Solar energy is abundantly available clean energy which be sufficient to overcome the future energy crisis. Solar panels usage is one of the clean and easy strategy to harvest the available solar energy. The temperature of solar panel increases when they are exposed to sunlight which causes a significant decrease in its efficiency and life. In the present study an attempt is made to overcome this problem by applying cooling mechanisms. An experimental setup consisting of a solar panel integrated with water cooling system is used here. Two different shapes of ducts are considered to examine their effect on solar panel efficiency. Water is circulated in circular coil and a rectangular duct which were attached at the back of solar panel. Temperature with output power variations for the three cases, i.e. without cooling system, with rectangular duct and with circular coil, were noted for period of time. A significant increase in efficiency of solar panel is observed when cooling system is integrated with it. The average efficiency values of solar panel without cooling system with coil system and with rectangular duct system were observed as 0.8 %, 9.6 % and 17.3 % respectively. A comparison between the studied cases revealed that the efficiency of solar panel was higher when rectangular duct was used for water circulation. Moreover, application of cooling system will reduce the thermal stresses in the panel which will ultimately increase its life.
