Dimensionamento de sistema fotovoltaico conectado à rede aplicado a uma fábrica de polpas de fruta

Abstract

Facing the large rise of photovoltaics market, in parallel to the incentives and regulation of this sector, this work presents the fundamentals of the most important concepts of this topic and the methodology for dimensioning of on-grid photovoltaic systems. The frequent droughts, especially in the northeast of Brazil, have caused the worsening of energy crisis in the country because the hydraulic sources are responsible for about 65% of the national energy production. In this circumstance, the national energy crisis is beating small and medium consumers, whose energy billings have showed significant increases. As a solution, renewable energy sources have been gaining more and more space in Brazilian regions scenarios. A proof of this is that the photovoltaic energy had a record growth in 2015 and starts 2016 with perspective to grow up 300%. This work aims to guide those who seek viable solutions to lower their electricity costs by investing in on-grid photovoltaic systems. Are shown in detail the main relevant information for the correct sizing of a on-grid photovoltaic system. In order to implement a real design, it presents a on-grid photovoltaic system designed to meet 50% of the consumption of a fruit pulp factory, located in Caucaia, Ceará. The on-grid photovoltaic system scaling demonstrated to be capable of providing 49.62% of the average consumption demanded by the consumer unit, in addition, it was estimated that the payback time for the investment required for its installation will be in the ninth year of the system operation.
