RESUMEN: Este artículo analiza la degradación de potencia, respecto a condiciones estándar de medida, de seis generadores fotovoltaicos de diferentes tecnologías de célula: silicio cristalino y capa fina, instalados en la terraza de la Escuela Técnica Superior de Ingeniería y Diseño Indutrial de la Universidad Politécnica de Madrid durante un periodo de tres años y medio mediante la determinación de la tasa de degradación de dos parámetros: potencia en ”Condiciones Estándar de Medida” y Performance Ratio de corriente continua con diferentes métricas para reducir los efectos debidos a la temperatura, irradiancia solar y distribución espectral, este último factor muy importante para las tecnologías de lámina delgada. Para determinar estas tasas de degradación se utilizan métodos estadísticos de análisis de tendencia de series temporales. Los resultados muestran el método estadístico que suministra mayor precisión y contribuyen a un mayor conocimiento del comportamiento energético de los generadores fotovoltaicos de diferentes tecnologías bajo condiciones de operación a sol real bajo un clima continental como el de Madrid (España).
ABSTRACT: This article analyses the power degradation of six photovoltaic generators of different cell technologies: crystalline silicon and thin film, installed on the terrace of the School of Industrial Engineering and Design of the Polytechnic University of Madrid over a period of three and a half years by determining the degradation rate of two parameters: power in "Standard Test Conditions" and Performance Ratio of direct current with different metrics to reduce the effects due to temperature, solar irradiance and spectral distribution, this last factor being very important for thin film technologies. Statistical methods of time series trend analysis are used to determine these degradation rates. The results show the statistical method that provides the highest precision and contributes to a greater knowledge of the energy behaviour of photovoltaic generators of different technologies under operating conditions in real sunshine in the continental climate of Madrid (Spain).
