Análise de desempenho de uma usina fotovoltaica de 12 kWp na cidade de Sanharó Pernambuco

Abstract

A performance analysis can be done in more than one way, either through manual calculations and measurements or using software and centralized monitoring devices, which is the case of this study. The main objective of this work consists of four steps: To study a photovoltaic plant, to propose and carry out modifications, and to follow the performance caused by the changes. Besides the main objective it is also reported an analysis of the factors that can cause energy losses in a photovoltaic system according to the literature, taking as base the plant located in the city of Sanharó, PE, the proposed changes have the focus of being practical and lowcost solutions with the purpose of improving its performance. The PV Sol software was chosen because it allows the user to perform advanced simulations regarding the types of connection between modules and shading analysis. The methodology is divided into five main steps that include the description and choice of the system, generation and mechanical and electrical layout survey, loss points in the system, simulation of configurations to reduce losses, and finally the economic feasibility and application. The results obtained demonstrate a 10.45% improvement in the system performance for the 112-day period considered, staying within the range of losses imposed by the integrating company responsible for the plant.
