ABSTRACT
Solar energy is a renewable and inexhaustible source, besides
causing damage to nature, being clean and sustainable.
Transform the electromagnetic radiation emitted by the Sun
electrical energy are used solar panels. In order to improve
efficiency and performance of this capture, a low-cost was
built, a single-axis solar tracking system for photovoltaic
panels. The solution uses the automation Arduino UNO R3,
open hardware, two photosensitive sensors LDR GL-5528, in
addition to a servo motor capable of moving the surface of a
photovoltaic plate according to the detection of the highest
incidence of light. The circuit and its components were
programmed using the Arduino IDE software, version 1.8.11.
As a result, it was possible to follow the movement of the
sun, differing from a static panel, thus ensuring greater sunshine
on the solar plate, as a result of this traceable
control prototype.
