Sistema fotovoltaico para empreendimento de múltiplas unidades consumidoras: análise de viabilidade técnica e econômica de implementação em um condomínio em Fortaleza-CE

Abstract

This work aims to perform a technical and financial viability study about the implementation of a photovoltaic system in an apartment complex in Fortaleza – CE. Based on normative resolution No. 482 of 2012, later revised by resolution No. 687 of 2015 wich presents the classification of micro and mini distributed generation in projects with multiple consumers, and in Technical Specification No. 122 of ENEL Ceará, wich regulates the access of the distributed generation to the distribution grid in the state of Ceará, the work presents a theoretical framework, and then proceeds to the Project of the proposed photovoltaic system, presenting the calculation methodology for the dimensioning of modules and inverters, and their simulation results, and finally, the financial analysis, calculating the Net Present Value (NPV) and the payback time for the initial investiment, analyzing the current scenario with the collection of ICMS taxes o the energy tariff in distributed generation and making a comparison with the older form of invoicing when there was exemption form this tax in the state of Ceará.
