Photovoltaic/thermal hybrid (PVT) is a solar panel system capable of producing electrical and thermal energy. This study aims to examine the effects of the internal fin diameter and angle on the surface temperature of solar panels and the water outlet temperature in the pipe. To increase heat absorption in solar panels, palm wax PCM is used. There are five parallel pipes in the palm-wax PCM, absorbing heat from it. This research uses ANSYS Fluent software, with variations in the internal flow diameter and the angular distance between fins. The inner flow diameter consists of 2, 3, 4, 5, and 6 mm, while the angle between the fins consists of 10°, 15°, 20°, and 25°. The results are obtained as PV Cell wall temperature, outlet temperature, and the mass of melted PCM during a three-hour simulation. Based on the simulation results, it can be concluded that the use of PCM and variations in the inner finned tube reduce PV Cell temperature.
