Sistema de microgeração de energia solar em cativeiro de camarões

Abstract

This study aims to analyze the technical and financial feasibility of photovoltaic microgeneration systems, taking into account the need to reduce electricity bills and increase energy tariffs. The initial phase of the work consisted of collecting data on the geographical location of the Chaval - CE and Barroquinha - CE farms, the model and power of the modules and inverters selected, as well as the irradiance and selection of the site for implementing the photovoltaic system. The process of generating photovoltaic energy, the equipment used, energy cost analysis, an explanation of the equipment that consumes the most energy in shrimp captivity and the merit index related to the efficiency, productivity, performance and losses of photovoltaic systems are also put into context. Subsequently, the system was sized for the Chaval and Barroquinha farms based on theoretical studies and it was found that 40 power modules of 665 Wp and 43 power modules of 550 Wp respectively were needed to meet the needs of the farms, with the aim of supplying demand at peak and off-peak times. Analysis of the energy bills revealed that the Chaval farm is charged in the A4 mode, while the Barroquinha farm belongs to the B1 sub-group, both covered by the Enel Distribuição Ceará concessionaire (formerly Companhia Energética do Ceará (COELCE)).After all the process mentioned above, the System Advisor Model (SAM) tool is used to calculate the monthly and annual energy production, accumulated credits and performance index for direct current (DC), alternating current (AC) to measure the efficiency of the system.
