Identification of thermal parameters of a solar photovoltaic panel in three-dimensional using finite element approach

boulfaf naima, Chaoufi Jamal


The focus of this study is to develop a computer program that simulates the thermal performance of photovoltaic (PV) panel. A detailed thermal model of a solar PV panel in three-dimensional using finite element approaches is established to determine the thermal parameters. The PV cell, glass, and tedlar temperatures are predicted. The influence of air velocity, solar flux, and ambient temperature are investigated. Simulation results indicate that whatever the value of air temperature and solar irradiance, the solar cell component has a high temperature. The obtained results also show that the PV panel temperature increases when the solar flux and the ambient temperature increases, consequently, the panel efficiency decreases. Finally, it is found that the highest value of wind speed causes the cooling of solar cells leading to the decrease of the PV panel temperature.
