Analysis of the Financial Viability of a Photovoltaic System to a Consumer Unit in South Brazil

ABSTRACT The photovoltaic solar energy is a renewable energy source that is growing in the Brazilian energy scenario, mainly after the approval of Normative Resolution (REN) n° 482/2012 of the Brazilian Regulatory Agency (ANEEL). This REN establishes the general conditions of micro and mini-generati...

This REN establishes the general conditions of micro and mini-generation access to the distribution system (distributed energy) and the energy compensation system (net metering). The evolution of photovoltaic solar technology coupled with the new perspective created by REN 482/2012, made many consumers unities to install a photovoltaic system (PVS). However, many aspects can be considered, for example, characteristic of the installation place, solar potential of the region, distribution network (DN), connection rules, as well as the financial economic analysis of installation and its maintenance. Thus, this paper presents an analysis of PVS installation in a commercial consumer unit in Florianopolis - Brazil, considering a system design to be connected to the local DN and their financial economic analyses. Different scenarios were simulated, ranging the aspects that may influence the investment return, like the self-consumption percentage, the tariff variations over the years, the tax incidences on the generated energy, as well as the variation in the PVS size. As a result, it can be seen in scenarios that the change in the tariff over the years, the form of acquisition through financing and the possibility of energy sales can be the things that most influences the return on investment. However, in Brazil, PVS financing and energy sale are not regulated to the consumer unit yet.info:eu-repo/semantics/openAccessUniversidad de Tarapacá.Ingeniare.
