Avaliação da viabilidade econômica de projetos de geração de energia fotovoltaica em duas regiões brasileiras

Abstract

The market for photovoltaic energy has been growing in Brazil since December 2012 when the Agência Nacional de Energia Elétrica (ANEEL) published the 482 regulation to facilitate the distributed generation of electricity, provided from renewable energy sources (Photovoltaic Solar Energy, Hydroelectric, Biomass, etc.). The present work has the objective of presenting a technical and economical feasibility study in different Brazilian regions for the implementation of a photovoltaic solar generation system connected to the distribution network (on-grid). Referring to the technical aspects of the development of the project, the following factors were taken into account: geographical position (location to be installed the system), levels of solar irradiance, angle of inclination of the photovoltaic modules and consumption demanded by the consumer for the dimensioning of power system. For a better presentation of the economic development, the economical engineering methods were used, which consisted of Analyzes of Minimum Attractiveness Rate, Cash Flow, Net Present Value, Internal Rate of Return and Payback. Through technical and economic analysis it is verified that the project becomes more feasible in the city of Sobradinho - BA, because due to the high rates of irradiation requires a lower cost investment and presents the VPL and IRR more attractive than in Joinville - SC. This is justified because of the best irradiation rates in this locality and also requires a lower investment.
