A wide portion of renewable energy comes from solar energy using PV panels. The maximum efficiency of a PV panel decreases below or above the operating temperature at 25 C using 0.5% of efficiency against every degree increase in PV panel surface temperature. This thesis develops a project set up to cool down the PV panel to its operating temperature. The setup consists of the rectangular heat sink, water sprayer, DC fan and thermoelectric regenerator (TEG). The main objective of this project is to maintain maximum efficiency by cooling down the PV panel. DC fans are used at the side of the panel, providing 1.5 m/s air velocity to enhance the forced convection heat transfer of the rectangular fin. Results show that the 10-15 C temperature of the PV panel can be reduced. By adding a water sprayer and TEG, further more than 15 C can be reduced. Experiments were performed with and without a cooling system for comparison and the results showed that the temperature was reduced by around 30 C and the efficiency was increased by 10-15%. The cooling system in this experiment could be automated to prevent overcooling to attain a predefined cooling effect and to save the waste of energy.
