Estudo de energia fotovoltaica para uma cidade inteligente

Abstract

The study proposed to qualitatively analyze the contribution of photovoltaic energy in cities, applied in this research, as part of initiatives in the contribution of technologies to a smart city. It is believed that it is still possible to contribute to the environment, through solar energy, a source of clean and sustainable energy, unlike most of the energy sources we use today, taken from nature in degrading ways. Solar energy has predominantly residential demand, but is also used in the commercial sector, such as public buildings, hospitals, restaurants, hotels, and other companies, whether large or small, but it has not yet reached its peak, and there is still much to be done conquer in the electricity market. However, it gains value every day, standing up to other types of energy generation, such as thermoelectric and hydroelectric plants. In this work, the objective was to study photovoltaic energy for smart cities, in order to predict the growth of solar energy in cities through applied questionnaires. The work sought to demonstrate concepts of smart cities and the study of renewable energies, as in this case, photovoltaic solar energy aimed at smart and sustainable cities. The different concepts of several authors about smart cities will be explained, as there are several models of these cities, but there is not a single defined concept. As a methodology for formulating the questions of the research instrument, a bibliographic research was carried out on smart cities with a focus on photovoltaic energy. The method used was based on the elaboration of a questionnaire, applied in an online form within a radius of a distance of 150 km (kilometers) from Cerro Largo-RS. Finally, to verify the efficiency, a case study was carried out in this radius of 150 km (kilometers), which found that 45.7% of respondents are interested in acquiring photovoltaic energy, in the long term, thus developing an urban environment in transition to sustainability. The information was collected through a semi-structured questionnaire, and a literature review, in which we sought to present a scenario of the theme of smart cities, and to present the trajectory of Brazil in the context of the development of technologies. The research has a qualitative approach, exploratory objective and was contemplated through projects related to smart cities and photovoltaic energy. As for the method, it proved capable of measuring the potential of photovoltaic solar energy in cities; however, it is an initial proposal, which can still be improved through future studies.
