Software para auxílio a projetos de sistemas fotovoltaicos conectados à rede elétrica.

Abstract

In the last years, the solar photovoltaic installed capacity has increased extremely. The evolution is justified by the environmental problems related to the fossil fuels, the fact that these fuels will be depleted and increasing demand for energy. Furthermore, with technological advancements and rising popularity of the photovoltaic systems, they are getting cheaper and more efficient. This dissertation develops a software application for designing grid-tied solar systems, in order to incentive research and use of these systems in Brazil. This work presents a review of important topics about solar energy. Moreover, this work shows some modeling for devices used in photovoltaic systems, as modules and inverters, and for variables that affect the performance of the systems, as temperature and solar radiation. Therefore, requiring a small amount of data input from the user and using a set of data which is available for many locations, this work purposes to design photovoltaic systems. The correct sizing of these systems allows analyzing the better conditions to implement them and avoid problems after their installation.
