Etude Dimensionnelle D’une Installation Photovoltaïque

Abstract

Our objective is to study the dimensions of photovoltaic installations. This study in clouded both theoretical and practical aspects of computer-controlled photovoltaic equipment technology using SCADA (EESFC), we conducted a research and a sizing and maintenance study of photovoltaic installations for an already existing primary school, and in order to correct errors that occur during installation. The most important issue we have addressee dies whether the installation of PV systems depends on an estimate or depends on the dimensionality of a PV installation. In order to solve the problem and answer all questions, the study included five chapters, through which we discussed: The general idea of renewable energies, including solar thermal and photovoltaic energy. Then weigh lighted the study of the photovoltaic solar system and the operating principle of cells. We have also in traduced the different concepts that go into the composition of the PV assembly system, more precisely the stand-alone system. Our calculations were obtained with the technology of computer-controlled solar photovoltaic equipment using SCADA (EESFC). Our results show that the short circuit current is directly proportional to the intensity of the radiation and this also applies to the circuit voltage. The increase in energy is done by increasing the radiation. In addition, lighting and temperature are key factors that modify the characteristics of a photovoltaic generator. Finally, for a technical-economic study of the maintenance of photovoltaic installations to produce the electrical energy necessary to supply a primary school. Our results have led to the fact that the installation of photovoltaic systems requires a careful study of the size and the installation, which is not limited to the only estimate, in order not to make mistakes that lead to malfunctions, and therefore the impossibility of supplying the product.
