Avaliação da eficiência de protótipo solar de baixo custo com movimento baseado em sensor de luminosidade

Abstract

The study proposes the use of a microcontroller to carry out the shading board project based on the Arduino platform. For this, a light sensor (LDR 10mm) is used to provide the inclination about the sun's rays, so that the microcontroller used is capable of tracking the sun to study the effects of such tracking on the efficiency in capturing the sun's rays, thus generating an electrical signal directly to the person responsible for the microcontroller. A mechanism is proposed that has its orientation based on the maximum incidence of solar rays on the surface of the solar cell, thus making the directional alignment with the photovoltaic plate at an angle with azimuth and height of the direct sun with the intensity of solar radiation. For this, two servomotors are used and with the inclination that can vary in the two axes: North / South and East / West. In addition to the servomotors, a microcontroller was used. The shading plate forms a rectangle, due to the position of the four light sensors, to control components directly connected to the servomotors. The embedded software is made by algorithms that allow the microcontroller to determine the correct position of the prototype solar panel. Initially, the characteristics of the proposed system are described and, using this apparatus, it is expected to generate electrical energy and increase the power in capturing with low-cost equipment
