iabilidade técnica-financeira da implantação de energia solar fotovoltaica no processo de redução de gastos com energia elétrica no Hospital Municipal de Petrolândia - PE

Abstract

Bearing in mind that the consumption and costs of electricity from public agencies and institutions make up a large part of the total energy consumption in the country and that Brazil has, for years, had one of the most expensive electricity bills in the world, technical-financial feasibility issues are studied for the implementation of own energy generation systems from renewable sources in public buildings, in order to analyze possibilities to promote the reduction of these costs generated by the public sector. This work analyzes the application of photovoltaic solar energy generation to obtain the expected results in cost reduction. For this, it is important to know the concepts and the current moment of photovoltaic solar energy, understand and characterize photovoltaic systems, their specificities and available technologies, in addition to be understand and using financial indicators and technical criteria to conclude if it is feasible to carry out the project. Thus, an exploratory research with a qualitative approach was carried out, where bibliographic and data collection were carried out to analyze the technical-financial feasibility of the implementation of two photovoltaic systems designed to, in the first case, make the institution self-sufficient and in the second case be generate savings with partial cost reduction. In view of the above, it appears that the systems designed for a case study at the Municipal Hospital of Petrolândia-PE, proved to be technically viable and that the savings rates throughout the life of the project pointed to high profitability in the investment. The NPV, IRR and Payback values found were satisfactory. It is concluded, then, that the project is successful and can be a relevant alternative and of considerable contribution in the search for greater efficiency and energy in the use among public institutions.
