Economia de energia: estudo da eficiência energética e dimensionamento de um sistema fotovoltaico residencial na cidade de Manaus/AM

Abstract

The present study aims to analyze the electricity consumption through a bill and size a photovoltaic system of a residence in the urban area of Manaus/AM, evaluating its financial feasibility in the current energy economy scenario. The work starts with the introduction of basic concepts about photovoltaic generation and elements that make up a photovoltaic system. The residence's electricity bill is analyzed, and a technical evaluation of the available locations for the installation of photovoltaic modules is carried out, as well as local data such as solar irradiation found through a web tool and project consideration criteria. Then, the models of the commercial equipment that make up the photovoltaic generation system are chosen, and the system is budgeted. With the aid of computational tools, financial indicators such as net present value, internal rate of return, and payback are found. The results show that the system is viable both technically and financially.
