Projeto e implementação de um sistema seguidor solar de 2 eixos para painel fotovoltaico

Abstract

Solar energy is an inexhaustible source of energy and was always present in our lives, it is also considered a promising alternative energy source to face the challenges of the expansion of energy supply with less environmental impact. However, the developed technology that enables its uptake and transformation into electricity is recent and has a vast field for research and development. This work proposes a more efficient solution in the capture of solar energy, which aims to design and develop a biaxial orientation mechanism that automatically positions the face of the photovoltaic panel at a right angle to the sun's rays during the day, and that is also able to generate electricity for themselves and other consumer source. At sunset, the solar panel returns his face to the east, staying at stand-by mode until the next day. The mechanical structure is essentially made of aluminum. The electronic circuit is analogic, and uses the potential difference between two LDR (Light Dependent Resistor) to drive an electric actuator, which will move the panel so that it is always perpendicular to the sun. The ideal battery for use in a collector system solar energy is presented. Also they present the problems encountered during the execution of the work, as well as the solutions found.
