Análise sobre a redução da eficiência em sistemas fotovoltaicos devido ao acúmulo de impurezas

Abstract

This work aims to analyze the influence of the accumulation of impurities on the efficiency of photovoltaic systems through a comparative study conducted in the city of Ivaiporã, Paraná. The rationale for the research lies in the growing importance of solar energy as a sustainable source and the need to optimize its performance, especially in view of the challenge posed by the dirt on solar panels, which can significantly reduce energy production. The methodology involved an extensive literature review, followed by practical experiments with 6V photovoltaic cells installed in the field. Efficiency measurements were taken before and after cleaning the panels, using appropriate measuring instruments. The results indicated that the presence of dirt considerably reduces the system's efficiency, demonstrating the need for periodic maintenance to ensure optimal performance and extend the lifespan of the solar panels. The conclusion reinforces that regular cleaning practices are essential to maximize solar energy production, contributing to the economic and environmental sustainability of the photovoltaic system, as well as providing data that can guide future preventive maintenance policies.
