Sistema de monitoramento para detecção de falhas em placas fotovoltaicas

Abstract

This article describes a photovoltaic panel failures detection system proposal. It’s known that in small photovoltaic energy generating systems, as the residential ones, a failure in one of the panels can causes an effective impact in the generated power. This is due to the small quantity of installed panels in this kind of system. There is a necessity of a system which enables these failures detection, for further correction, resulting in better power generating performance. Whith the challenge of meeting this demand, the idea of this work emerged, which is based on using hardware and freeware software, where the hardware is responsible for measuring the voltage and electric current values and sending this information for a software running in a personal computer that receives the collected data and reports to the user the photovoltaic panel functioning status. A graphic interface was developed for viewing the received data and make the diagnosis. Both the software and the photovoltaic panel were tested, and the correct functioning of both was proven.
