Potencial de microgeração energética em pequenas e médias propriedades rurais produtoras de soja na cidade de Marau, RS

Abstract

This work presents a study of the evaluation of the potential of microgeneration of energy through photovoltaic panels in cover of small and medium rural properties of soybean farmers in the City of Marau, RS. It has a bibliographical review, concepts and actives legislation on the theme, national panorama and main users countries and producers of photovoltaic solar energy, besides that show the study area and economic analysis of profitability and feasibility of the installation of the systems of generation of energy. The regulatory forms of grid-connected distributed energy generation systems are verified, with two basic mechanisms, the price system or feed-in tariff, where the energy generated is remunerated by a premium rate and the system of quotas or net-metering, In which the energy injected into the grid is transformed into credits to reduce the generator's own consumption. Through measures of coverage of selected properties, an analysis was made of the potential of photovoltaic energy generation, in addition to the costs of investment and return to the producer. Was perceived a potential for energy production was realized, but with low return and high financial investment, when considering all the area that can be installed in the system, and therefore, the high cost and the form of compensation in the credit modality are the larger obstacles to the commercial advance of this form of energy generation.
