Estudo de eficiência energética e retorno de investimento para o uso de um veículo elétrico em conjunto com um sistema fotovoltaico instalado em Curitiba

Abstract

This monograph presents the analysis in terms of efficiency energy and financial - payback - of the Grid-connected photovoltaic system installed in a residence in Curitiba, followed by the comparative analysis of this result, now considering the owner of the residence using part of the accumulated energy in the form of credits for loading the batteries of an electric vehicle for his locomotion. The return on investment analysis was made with the actual database made available by the owner from February 2016 until February 2018. The results achieved are quite significant. In addition, to generating power directly in the unit where it is consumed - thus allowing the government to reduce investments in generation, transmission and distribution of energy - the owner generates energy from a renewable source: the sun. Once the SFCR is installed, the owner is saving about R $ 1,490 per year. Considering only the installation of SFCR, the calculated payback is more than 14 years. With the use of part of the energy generated to charge an electric car, the results achieved are quite expressive. By failing to use the current combustion car and moving around with the electric vehicle, the owner, in addition to using a totally carbon-free technology, achieves an extra-annual savings of $ 7,300.00, reducing the payback of the system for just over two years (approximately 700% reduction). It is undeniable that energy and economic alternatives such as those presented in this study are necessary for a sustainable future. In Brazil, unfortunately the incentive to these alternatives is deficient and therefore, studies such as those presented in this analysis are so important to promote knowledge in the subject and disseminate it.
