Viabilidade da geração de energia das placas fotovoltaicas no laboratório de sistemas de potência.

Abstract

Solar energy is a term that refers to the energy from the light and heat of the sun. It is used by different evolving technologies, such as solar heating, photovoltaic solar energy, solar thermal energy, solar architecture and photosynthesis artificial. Solar technologies are broadly characterized as either active or passive depending on the way they capture, convert and distribute solar energy. Among active solar techniques include the use of photovoltaic panels, among others. Due to the need of diversification of the Brazilian energy matrix and the quick expansion of the electrical sector, the renewable resources are an option of solution. For instance, photovoltaic systems are capable of generating electrical energy using photovoltaic cells, which are produced with semiconductor materials that creates electrical energy upon exposure to the sun radiation (photovoltaic effect) and it’s classified in three categories: grid-off systems, hybrid systems and grid-tied. In Brazil, these technologies are being slowly exploited compared to other countries like Germany, but there are ANEEL resolutions that standardize the use of distributed microgeneration. This paper studies the ways of use of a photovoltaic system, emphasizing the grid-tied system with an elaboration of a project for a typical residence and an economic viability analysis, using engineering economics techniques, indicating that the implementation of this project in the laboratory is uneconomical.
