Étude de l'énergie solaire photovoltaïque contrôle par ordinateur

Abstract

Solar energy is a clean and renewable source of energy that depends on the sun. This energy allows the production of electricity from photovoltaic panels or solar thermal power plants, thanks to the sunlight collected by the solar panels. In this final thesis, we used Photovoltaic Solar energy equipment controlled by computer with SCADA (EESFC), Equipment controlled by computer (PC), where the system consists essentially of two photovoltaic solar panels, solar simulator composed of solar lamps and storage battery and inverter, for the use of the energy delivered by the two panels. In order to describe the two photovoltaic solar panels, we have solved four exercises to study the characteristics of the two photovoltaic panels according to several individual configurations, parallel and series, and according to several parameters such as Rheostat, the intensity of lighting, use of fans…etc. It has been found that the maximum power value depends on the position of the rheostat. The intensity of the radiation is responsible for the power efficiency and the efficiency depends on the current intensity. In addition, connecting the two panels in parallel and in series increases the output current and the voltage respectively, as well as the characteristics of the panels supplied by the manufacturer have been verified and confirmed. Finally, the influence of temperature in the efficiency of the panels was recognized. In addition to some prospects in this technology.
