Estudo de viabilidade técnica e econômica para implantação de estacionamento fotovoltaico no campus Ecoville da UTFPR

Abstract

The present work aims to present the technical and economic feasibility study for the implementation of photovoltaic parking at the Ecoville campus of the Federal Technological University of Paraná. This study aims at the partial supply of the electric energy consumption of the campus, in order to minimize the costs of the University with the electric energy bill. The spaces destined to the parking of vehicles are in open sky and without the presence of obstacles that harm the incidence of the solar irradiation, factor that makes possible the installation of a system of photovoltaic generation. For the optimization of the plant we chose the use of the structure called solar carport, a support that allows electric generation and shelter to vehicles. Initially a research was carried out that deals with topics about the operation of photovoltaic systems and the main norms and regulations related to distributed generation. An analysis of the installation site of the system was carried out, where a total area of approximately 12 (twelve) thousand square meters (sum of the two parking areas) was verified. At the same time, data were collected on solar irradiation and information on the consumption of electric energy of the University during the period of one year. Subsequently, with the sizing of all components of the system, it was possible to raise project implementation costs, including materials, equipment and labor, where an initial investment of R $ 1,688,376.76 (one million six hundred and eighty and eight thousand, three hundred and seventy-six reais and seventy-six cents). The design resulted in two systems of minigeration, the first with power of 178.2 kW and the second with power of 158.4 kW. The total area occupied by the system is 1,700 m². Finally, the economicfinancial analysis of the system was elaborated and through financial indicators a payback of 7 years was estimated. Considering the conditions of generation and satisfactory period of return on investment, this study concluded that the proposed project is technically and economically viable.
