Stand alone photovoltaic management system for icts devices

Abstract

This article presents the development of a portable stand-alone photovoltaic system (SAPS) and the mathematical model that allows simulating its behavior and optimizing the design. The purpose of this system is developing an auxiliary source of energy for portable information and communication technologies devices (ICTs). The SAPS was implemented from a 20 Wp foldable photovoltaic generator and a 5200 mAh Ion-Lithium battery bank linked to a netbook from the Programa Conectar Igualdad of Argentina (PCI). The model validation was carried out through experimental results obtained by testing a specific application of this type of systems. The results demonstrate an optimization of the equipment fed by the system (netbook), increasing autonomy by 5 hours on a clear day in a month of winter in the city of Corrientes, Argentina. By comparing the theoretical and experimental results it was possible to verify an adequate development of the system for the specific application and the utility of the model as a systems design tool for this type of applications.
