Abstract

Nowadays,solar energy becomes popular as a renewable energy to support the demand of electricity due the increasing population of world.It also no pollution and the most important is infinite source.However,solar energy have limitation where it have their optimum temperature that will influence their efficiency. According Standard Test Condition (STC) the optimum temperature is 25°C and it performance will drop due rise temperature and cause more heat energy will produced.The unwanted heat must be release from the panel to produce higher output power.The aim for this research is to improve the efficiency of solar panel during noon by using passive cooling method.In this experiment,two different design of heat sink are used that is normal fin and mixed fin to compare their performance to cooling solar panel.The results of the experiment shows that mixed fin better than normal fin with efficiency 7.11% and 6.6% respectively.To obtain better results portable are used to speed up cooling process through front and bottom surface through convection and conduction process, it prove that by using speed 3 (3.3m/s) their efficiency will increase for both types of the where mixed fin is 8.94 % while normal fin 8.44 %.
