Energia solar fotovoltaica: viabilidade na geração de energia limpa no semiárido alagoano

Abstract

This work intends to obtain a simple and efficient way of studying the generation and use of photovoltaic solar energy in regions of the Alagoan semiarid region, using the technology of monocrystalline and polycrystalline solar panels. Therefore, the overall objective of this research is to design and implement photovoltaic systems for electric power generation in the backlands of Alagoas. In view of this, the specific objectives are: To carry out a theoretical study on renewable and sustainable energies in the semiarid; Studying the development of clean energies in the hinterland; Verify and analyze the feasibility of deploying photovoltaic systems for electricity generation in Delmiro Gouveia. About the research methodology, this is applied nature, it is classified as being an experimental research and uses the qualitative and quantitative approaches. Initially, for the development of this research was made a selection of materials (scientific articles, digital magazines, books, websites, etc.) for theoretical study and better understanding of the theme. Among the references used to support this research are Villava (2012), CRESESB (1999), Halliday (2008), ANEEL (2012), among others. In the results, it was noticed that the plates presented a very effective behavior as in the question of maximum power voltage, maximum power current and power allowance interval, which in the monocrystalline field plate obtained respectively the values of: 14.8V, 4.2A and 62.16W and in the field polycrystalline plate: 12.6V, 4.0A and 50.4W. These results were extremely satisfactory, as they approached the results in a controlled laboratory environment, where conditions are perfect. It is also worth noting that the current hardly varied during the entire test, which is conducive to a photovoltaic system feeding resistive loads such as: lamps, sockets, etc. In this context, it is assumed that the idea of photovoltaic energy in Delmiro Gouveia - AL will obtain the highest possible yield in this region. Therefore, it is considered that this work was of great relevance for the acquisition of new knowledge in relation to the subject matter addressed here, and especially for the enrichment of the professional in Civil Engineering.
