Análise da sujidade na eficiência energética das placas fotovoltaicas por meio de processamento de imagens

Abstract

This work presents a study of the interference of dirty on photovoltaic solar modules efficiency by analyzing photographic images based on RGB format. The main objective is quantify the intensity of dirt deposited on photovoltaic panels and relate it to the impact it has on reducing the system's efficiency. The methodology adopted consists of evaluating the performance of photovoltaic solar panels by means of comparative tests with different levels of dirt, using photographic images, associating the efficiency of photovoltaic generation with the responses of the intensity levels of the colors obtained in the RGB standard. As a result, an equation was obtained that can be applied to real situations in solar photovoltaic systems, estimating the percentage by which dirt affects solar energy production. In this way, it is possible to mitigate damage to the system and develop periodic maintenance and cleaning plans, ensuring maximum system efficiency and preserving the useful life time of the solar modules.
