Preventive diagnosis of photovoltaic facilities based on the interpretation of infrared images

Abstract

Currently, Cuba is struggling to increase the presence of renewable energies in its energy matrix, this in order to reduce dependence on fossil fuels and help curb global climate change. One of the missions of the National Electric Union is to expand the installation of photovoltaic parks throughout the national territory and achieve efficient use of them. The present work aims to present examples of the diagnosis of different types of failures in such facilities, based on the interpretation of infrared images by means of the thermal contrast method It seeks the analysis of non-destructive infrared images of photovoltaic installations, with the goal of detecting failures due to heating of the parts that compose them. The execution of this type of preventive diagnostics, helps to plan maintenance or to carry out immediate repair actions that allow maintaining the efficiency and generation capacity of the photovoltaic parks.
