Abstract
El objetivo de este trabajo es implementar una metodología que pueda determinar el desempeño de los módulos solares enfocándose en los efectos de ensuciamiento y degradación. Este estudio se realizó en las dependencias de la Universidad Federico Santa María, Campus San Joaquín, Santiago de Chile. Se recolectan datos meteorológicos, térmicos y eléctricos para analizar el desempeño de un panel sucio, un panel quebrado y dos paneles limpios desde fines de mayo del 2019 hasta diciembre del 2020. Se realiza la obtención de un índice de desempeño denominado performance ratio y mediante esta base dato se procede analizar el efecto de ensuciamiento y la degradación de estos mismos. Las tasas de soiling no fueron influyentes para los paneles 2 y 3, cuyo soiling rate promedio fue levemente superior a 1[−],en cambio, el panel 4 tuvo un soiling rate promedio 0,986 [−]. Por otra parte, las tasas de degradación de los paneles obtenidas revelaron la pérdida de potencia para cada módulo, siendo el módulo 3 el que sufre la mayor tasa de pérdida de potencia. La metodología implementada mostró buenos resultados en las detecciones de anomalías en la potencia de salida
The objective of this work considers the implementation of a methodology that can determine the performance of solar modules focusing on the effects of soiling and degradation. This study was carried out at the premises of the Universidad Técnica Federico Santa María, San Joaquín Campus, Santiago de Chile. Meteorological, thermal and electrical data are collected to analyze the performance of a dirty panel, a broken panel and two clean panels from the end of May 2019 to December 2020. A performance index called performance ratio is obtained and through this Data base we proceed to analyze the effect of soiling and their degradation. Soiling rates were not influential for panels 2 and 3, whose average soiling rate was slightly higher than 1 [-], whereas panel 4 had an average soiling rate 0.986 [-]. On the other hand, the degradation rates of the panels obtained revealed the loss of power for each module, being module 3 the one that suffers the highest rate of power loss. The implemented methodology showed good results in detecting anomalies in the output power
