Construcción de un cargador eléctrico a partir de energía solar para dispositivos electrónicos ESFOT-EPN

Abstract

The solar energy, which is the principal input of this project is a renewable energy, unconventional, unlimited, but principally clean and friendly with the environment. The device constructed takes advantage of this natural resource to generate something as important nowadays as the electricity power. The present work presents in a general way: the importance, the working principle, the components and the main characteristics of a photovoltaic solar system isolated from the network, and how this system is used for the construction of an electric charger of electronic devices in the ESFOT-EPN. The process for estimating the charge of the electric charger from solar energy is described and the principle of operation of all the components is also indicated, such as: the solar panel, the solar charge battery, the charge regulator and the load conditioning circuit. The process for the sizing and selection of each of the components, protections and other elements that are part of the electric charger is explained in detail. The summary of the costs of the project is presented and finally the results of the electrical and mechanical tests of the device are shown, which guarantee the correct functioning of the electric charger from solar energy implemented. The results obtained from the tests realized on the device show that the design, dimensioning and construction of the electric charger based on solar energy complies with the quality standards necessary for its normal operation.
