Estudo de viabilidade técnica e implantação de um sistema de microgeração fotovoltaica residencial

Abstract

The electrical energy generation increases necessity to supply the countries demands, affected by the energy cost utilization, that invariably is generated several kilometers away from huge demanders centers, leads for a more technical and financial attractive solution. On the other hand, but reinforcing the point, there is a big global pression to use more renewable electrical source, less offensive to the environment, as an alternative to move the actual energy matrix to a new and less fossil dependent scenario and by consequence supported by the renewable sources. This project intends to touch all these aspects, it means, plan and implement a decentralized micro grid connected photovoltaic system, suppling a residence energy consumption and injecting the energy surplus to the system. This surplus could be used later at the same residence or in a different residence using the compensation concept. The project approach is not only a feasibility case study but a real planning, execution and monitoring system project, confronting the calculated values with the real results. The reach the target, three residences were analyzed to be selected to receive the new plant. The selection process used the best technical conditions, maximizing the energy generation potential, minimizing the costs and the time to set the project. All the legal process and the power distribution company requirements were followed to connect the photovoltaic system to the grid. As a final step, the system was monitored and the collected results were compared with those calculated proving the energy generation system efficiency and the energy compensation process.
