Dimensionamento e projeto de um sistema solar fotovoltaico.

Abstract

Solar energy can be considered inexhaustible, and also the applications coming from it. This work explains concepts such as irradiation and insolation, and how these relate to photovoltaic systems equipment, such as solar modules or frequency inverters. This work of completion of course had as main objective, to explain and to describe, in the best way possible, the design of these systems, to be connected to the network, the so-called on-grid systems. This work took as example a company with the conditions to invest in the design of a 109 kW Minigeneration plant, which has to be able to reduce the dependence of the public energy distribution network and still be financially viable. From the point of view of electrical installations are dimensioned cables, circuit breakers, fuses, numbers of solar modules for a certain region and its organization. And from an economic point of view, the price of this project is surveyed to verify its economic viability, and financing possibilities are listed.
