Estudo de custos de implantação e retorno financeiro de um sistema de geração fotovoltaica

Abstract

Considering that Brazil, due to its climate and geographic aspects, has a great potential for photovoltaic energy generation, however the photovoltaic generation capacity in the country corresponds to less than 2% of the national energy matrix, which matrix is highly dependent on hydroelectric plants and that suffers constantly due to water crises. This work presents a study demonstrating the costs involved in the implementation of a on-grid photovoltaic generation system, as well as the financial return promoted by the use of the system in the short and long time, in order to demystify the subject and disseminate knowledge for this type of energy. be more widely used. To this end, it is shown how the sizing of the system was done, the survey of costs, the calculation of the energy generated over 25 years and the calculation of the values to be reduced from the energy bill with the use of the system. Using an economic indicator, a prediction of the return obtained by using the system in subsequent years was made. Given this, it was possible to see the quick return on investment spent on a photovoltaic generation system, as well as its high profitability from the energy values saved over the years.
