Protótipo de um rastreador solar de dois eixos e mapeamento solar com firmware de controle independente da irradiância

Abstract

In order to diversify the Brazilian energy matrix, alternative sources have been implemented in the country. Since its first appearance on national territory, solar-photovoltaic energy has increased by 2400 times since its initial contribution in 2012 when compared to last year’s data. Part of this development is due to the low cost of generation and ease of access to the means of energy production. Technologies are constantly being developed to optimize this source of generation, and the most effective of these is the solar tracking system. For this reason, two hypotheses have been put forward: one defends the possibility of developing accurate tracking firmware that can be implemented in numerous regions. The second is based on the idea that tracking on one axis considerably increases the solar generation gain, while two axes further optimize this process. That said, this project was based on building a Prototype of a Two-axis Solar Tracker and Solar Mapping with Irradiance-Independent Control Firmware. The results show that the firmware developed is replicable for all regions of the planet. Furthermore, the implementation of tracking on one axis resulted in an increase of 29.58% when compared to fixed modules, even in colder periods. The second axis increased the gain to 1.89%, justified by the adversities faced in relation to the structure of the project. In addition, the hypotheses were validated throughout the work, the project for future academic studies.
