Dimensionamento de sistema fotovoltaico off-grid para Escritório móvel

Abstract

Facing the fierce competition in the infrastructure services execution segment, whether civil, electrical or electromechanical works, companies need to reduce operating costs, optimize resource utilization and shorten deadlines to present lean budgets resulting in a proposal with final price competitive. Operating in these aspects is the use of mobile offices, reusable, sustainable and independent of the electrical system capable of providing support for construction sites in hard-to-reach places. These mobile offices use marine containers as alternative materials for building offices that until then were masonry, thus providing a reduction in the time of mobilization of the works, offering the necessary conditions to start activities, such as adequate lighting, thermal comfort and network of communication, counting on photovoltaic system off-grid generating energy for consumption and storage in batteries. Conventionally, the offices use the external networks of the local concessionaire as power supply, but in isolated regions this connection is often not possible in a timely manner, so diesel generators and solar photovoltaic systems are available as alternatives. In this context, this work compares the total costs for the implementation of energy supply alternatives, showing that the use of photovoltaic systems besides being a sustainable alternative is economically viable.
