Simulação e análise de viabilidade econômica de sistemas solares fotovoltaicos conectados à rede.

Abstract

Every year, the investments in alternative sources of energy that aim to reduce the global dependence on fossil fuels increase significantly. In this context, solar energy appears as a strong competitor when it comes to clean energy. Brazil is located in a favorable region for developing this kind of project due to the elevated intensity of solar radiation on its territory. However, the costs of photovoltaic systems are still high in comparison to the main form for generating electricity in Brazil: hydroelectric. In the last few years, the incentives have increased so that in April 17, 2012, the Brazilian Electricity Regulatory Agency published the Resolution 482, which gives any Brazilian citizen the right to generate his own energy and to send the excess back to the distribution network, gaining energy credits by doing so. As consequence, there is a lot of discussion about the On-Grid Photovoltaics Systems and the economic viability of its implementation. By using simulators and financial analysis methods, some answers can be obtained to reinforce the discussions on the issue.
