Abstract—Mathematical simulation of plat–pin fin heat sink installed under solar panels was conducted. Based on the problem of heat accumulation inside the solar panel, the electricity generation efficiency become reduced with a higher heat. Thus, the objective was to design and simulate plate and pin cooling. Two shapes of pin consisting of plate and cylindrical pin were studied. The investigated process was divided into two stages. The design and calculation of the heat sink fin was the first stage. The process of simulating solar panels with fins attached and without fins using the SOLIDWORKS program was the second stage. Three factors were considered: the direction of the panel installation (S, SE, and SW), the inclination angle () of the solar panel, and the style of installation (Transvers and longitude fins). The appropriated condition for reducing the temperature of solar panels was discussed. The results showed that the minimal temperature of the solar panel was obtained at the southeast (SE) direction with an inclination angle () of 18°. Heat dissipation was achieved by the transvers fins in which a maximum temperature reduction gave 6.39 ℃.

Keywords—Heat sink, solar panel, temperature reduction
