The main objective of this study is to optimize the production of electricity from a photovoltaic (PV) plant with a capacity of 50MWc. The power plant is located near the city of KITA, Mali, in an area whose climate is characterized by high temperatures. However, the temperature of photovoltaics cells plays a key role in their performance, which deteriorates when the temperature increases. In this study we focus on the analysis of laminar forced convection flow around a PV panel, main element of a photovoltaic plant, considering the ambient temperature, irradiation as well as the velocity and the direction of the wind. Several operating configurations were analysed in relation to the specific climatic conditions of Mali for a typical day of sunshine with a daily irradiation of a duration of 12 hours between 6:00 and 18:00. The mass transport, momentum and energy equations are solved numerically using the finite volume method. This method is based on the spatial integration of transport equations with respect to elementary control volumes. Computer simulations are performed with ANSYS Fluent® CFD commercial software. Our results show that considering the effect of wind plays an important role in the temperature estimates of photovoltaic cells and that accurate knowledge of this behaviour is essential for optimizing production.
