Análise da viabilidade técnica de painéis solares fotovoltaicos conectados à rede em uma fazenda de produção de camarão em Alto Santo/ CE

Abstract

As a result of the growing demand for clean electricity generation, obtained from renewable sources, whose purpose is to reduce the effects of global warming and decrease production costs, solar generation, through photovoltaic panels, has become more and more attractive. When compared to the 1990s, photovoltaic panel technology, as well as control systems, has seen significant technological growth. The installation and generation costs have fallen to less than 50% compared with the start of the mass diffusion of this application at the beginning of the new millennium. Besides this, the inclusion of commercial partners such as China, Denmark, Germany, among others, has increased competitiveness, lowering the market price, and ceasing to be a product that before came exclusively from US imports. In this work the technical and economic viability of the implementation and use of a microgeneration system based on solar energy, produced by solar panels and a control system, such as frequency inverters and other power electronics equipment, was evaluated, with this system connected to the distribution network of the local utility (on-grid). The final application of this solar microgeneration will be to supply a shrimp farm, carcinicultura, in the city of Alto Santo, located in the Jaguaribe Valley. The technologies, solar irradiation data, and the possibility of installing photovoltaic modules on the entire roof of the area and, consequently, the percentage of energy saved with the use of the system and its economic viability were analyzed.
