The satisfaction of the energy needs of a computer laboratory requieres a systematic study of the consumption of the various electrical receivers listed. A compromise must be found between the time of use of these receivers and the number of needed to be connected to the photovoltaic power source in order to minimize, as much as possible, the daily energy consumed by the installation. We note the peak power (P_c), the number of the panels (N_(pa,t)), the power of the inverter (P_Ond) and the current of the regulator (I_rég) are lineary a function of the daily energy (E_cj). The total number of batteries (N_(b,t)) is a linear function of the daily energy (E_cj) and the autonomy of the battery bank (N_Au). In this paper, we propose a simplified and reliable method for sizing, selecting and wiring of the photovoltaic components in order to ensure an effective and secure supply of electrical energy.

Abstract
The satisfaction of the energy needs of a computer laboratory requieres a systematic study of the consumption of the various electrical receivers listed. A compromise must be found between the time of use of these receivers and the number of needed to be connected to the photovoltaic power source in order to minimize, as much as possible, the daily energy consumed by the installation. We note the peak power (P_c), the number of the panels (N_(pa,t)), the power of the inverter (P_Ond) and the current of the regulator (I_rég) are lineary a function of the daily energy (E_cj). The total number of batteries (N_(b,t)) is a linear function of the daily energy (E_cj) and the autonomy of the battery bank (N_Au). In this paper, we propose a simplified and reliable method for sizing, selecting and wiring of the photovoltaic components in order to ensure an effective and secure supply of electrical energy.

Abstract: (french)
La satisfaction du besoin énergétique d’un laboratoire informatique requiert une étude systématique de la consommation des différents récepteurs électriques répertoriés. Un compromis devra être trouvé entre le temps d’utilisation de ces récepteurs et le nombre des récepteurs nécessaires à brancher à la source d’alimentation photovoltaïque afin de minimiser, le mieux que possible, l’énergie journalière consommée de l’installation. Nous constatons que la puissance crête (P_c), le nombre des panneaux (N_(pa,t)), la puissance de l’onduleur (P_Ond) et le courant du régulateur (I_rég) sont linéairement fonction l’énergie journalière (E_cj). Le nombre total des batteries (N_(b,t)) est linéairement fonction de l’énergie journalière (E_cj) et de l’autonomie du parc des batteries (N_Au). Nous proposons dans cet article une méthode simplifiée et fiable de dimensionnement, de choix et de câblage des composants photovoltaïques afin d’assurer une fourniture en énergie électrique de manière efficace et sécurisée.
