Viabilidade da geração solar de uma residência típica.

Abstract

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.
