Comparativo entre rendimento e custo benefício de telhas solares e painéis fotovoltaicos convencionais em instalações residenciais

Abstract

This work has as main objective a comparative analysis between photovoltaic tiles and solar panels, with regard to performance, cost-benefit analisys and financial return, in addition to contemplating the technological differences applied and the types of installations of both. A load survey have been carried out on a residence located in the city of Curitiba – PR, in addition to mathematically proving which of the two technologies has better efficiency and financial return. For the payback analysis, annual adjustments and current rates with taxes are taken into account. In addition, the work will draw a comparison between solar energy in Brazil and in the world, presenting the growth in the use of renewable energies, which has been intensifying more and more over the years. When comparing the results, it is possible to see that the photovoltaic panels become a more technically viable alternative, since the calculated indices as well as the payback obtained better results, but the Evolution of technology in the development of photovoltaic tiles may cause this scenario to change in the near future.
