Projeto de sistema fotovoltaico isolado para uma área rural em sistema com banco de baterias: análises das viabilidades técnica e econômica

Abstract

With the growing need for the use of renewable energies in Brazil and in the world, the use of photovoltaic systems to generate residential energy is gradually increasing over the years. With the objective of demonstrating the financial and technical impact of the use of photovoltaic energies in Brazil, this work addresses the technical and economic feasibility of a photovoltaic system for a rural area in a system with a battery bank. A residence in the city of Alegrete - RS was used, being of the class B1 type – single phase 220V. The technical analysis encompasses all calculations for sizing the photovoltaic system, while the economic feasibility analysis used this calculations to define whether the system was viable for implementation, these calculations are: Net Present Value, Internal Rate of Return and Payback Discounted. The Project presented positive results for all the conditions imposed to define viability.
