Dimensionamento e análise financeira de uma microgeração de 56,61 kWp, utilizando o Sistema de Carport Solar

Abstract

In this work, a Photovoltaic System (SFV) project was developed to supply the consumption of a club in an allotment in Eusébio, using a solar carport system, followed by a financial analysis to evaluate the feasibility of the implementation. Initially, the growth of the implementation of SFV in Brazil and in the world was exposed, in addition to demonstrating the reasons for this growth. Subsequently, the components of a PVS and their respective functions were introduced, in addition to addressing the main normative resolutions that impact Grid-Connected Photovoltaic Systems (SFCR). For sizing the SFV and generating electricity, the average annual consumption was used, resulting in a power of 56.61 kWp and 102 modules, and selecting a 40 kW inverter that had the capacity to serve the system. It was verified whether the available space has an available area for the installation of the solar carport. The generation in 25 years was estimated taking into account the losses in the generation capacity of the modules. Savings were also calculated, comparing the energy bill with the SFV and without the SFV over a period of 25 years. Finally, the implementation costs were analyzed and compared with the savings obtained. The financial analysis demonstrated a Net Present Value (NPV) of BRL 576,234.52, an Internal Rate of Return (IRR) of 44% and a Discounted Payback of 3.25 years.
