Abstract: Paper An experimental study has been conducted to control the solar panel temperature during the peak noon hours. Due to the high solar intensity during noon hours, the solar panel temperature attains very high temperature in the range of 65°C to 70°C. High temperature is not advisable for the better performance of the solar panel. Hence to control the temperature, some heat removal method has to be considered. In this study, air has been considered as a cooling medium as it is available abundantly. To predict the effect of the cooling medium (air), experiments are conducted without cooling medium and with cooling of panel from the top or from the bottom of the panel. Parameters like glass temperature, power generation and efficiency of the solar panel are compared for the three types of experiment (without cooling, with air cooling from the top and air cooling from the bottom of the panel). It is concluded that solar panel can be maintained in the range of 40°C to 45°C with the cooling arrangement and short circuit current can also be maintained in the range 13 Amperes to 15 Amperes, whereas without cooling, short circuit current varies in the range of 9 Amperes to 15 Amperes. Hence the power generation is maintained in the specified range. Comparing the cooling of panel either from top or from bottom of the panel it is concluded that cooling from the bottom is more effective as thickness of the Tedlar plate is less than thickness of glass cover.
