Abstract
En este documento se presenta el trabajo realizado para el diseño de un laboratorio de envejecimiento acelerado por radiación ultravioleta. Para esto, se hizo una revisión de las metodologías utilizadas actualmente en laboratorios alrededor del mundo y luego se seleccionaron equipos y materiales para reacondicionar una jaula de Faraday y construir una cámara climatizada donde se controlen radiación y temperatura para realizar la prueba de precondicionamiento UV descrita en la norma IEC 61215. Se revisaron los requisitos para la realización de las pruebas de calidad de módulos fotovoltaicos que deben realizarse antes de la prueba de precondicionamiento, añadiendo procedimientos que aumentan la capacidad de evaluación de los módulos. Se identificaron los parámetros para hacer pruebas de degradación más exigentes que caractericen la operación en climas específicos, adoptando una metodología ya probada y modificándola para obtener resultados más representativos de climas con alta radiación UV.
This document presents the work done for the design of an ultraviolet radiation accelerated aging laboratory. For this, a review of the methodologies currently used in laboratories around the world was carried out and then equipment and materials were selected to recondition a Faraday cage and build an environmental chamber where radiation and temperature are controlled to performthe UV preconditioning test described in the IEC 61215standard. Additionally, the requirements for the photovoltaic module quality tests that must be carried out prior to the preconditioning test were reviewed, adding procedures that improve the capacity of evaluation of modules. The parameters to carry out more demanding degradation tests that characterize the operation in specific climates were determined, adopting an already proven methodology and modifying it to obtain more representative results in climates with high UV radiation.
