Procedimentos para a instalação de um sistema fotovoltaico de geração de energia distribuída em uma residência: estudo de caso

Abstract

Increasingly, consumers are looking for alternative sources of energy, aiming for sustainability and economy, in this sense the demand for photovoltaic solar energy grows by the reduction of the costs of the systems due to the advances in the technology, the increase of the energy bill, mainly in the periods the red flag prevails in the consumer invoice. The objective of this work is to demonstrate the difficulties related to the installation of a photovoltaic generation system in a residence. The method used to elaborate this work was the case analyze the procedures for the installation of a photovoltaic generation system in an existing residence, resulting in the demonstration of the difficulties encountered as the lack of grounding and space in the distribution frame of the installation, up to the state of conservation of the tiles and lack of anchorage point for the realization of works in height for installation of the photovoltaic panels in the roof. It has also been demonstrated as a result the system's power generation from the installation, reaching an average value of 174kWh per month, representing a return on investment in approximately five years.
