Este artículo tiene como objeto evaluar la incidencia de la geometría del área de reflexión en el rendimiento óptico de un sistema a baja escala de concentrados cilindro-parabólico. El sistema fue desarrollado y probado para calentar agua o generar vapor de agua en las Unidades Tecnológicas de Santander, ubicadas en Bucaramanga, Colombia. Se tuvieron en cuenta factores ópticos del prototipo real para realizar un análisis de trazado de rayos de monte Carlo, aplicando la Herramienta SolTrace. El sistema de concentración real, fue sometido a una comparación con dos sistemas geométricamente diferentes, es decir, un concentrador con dimensiones inferiores al sistema real y uno con dimensiones mayores, con el fin de determinar los rendimientos ópticos y las relaciones de concentración, para determinar la relación existente entre estos dos parámetros y el rendimiento de la unidad. Los resultados obtenidos, mostraron que el área de reflexión afecta directamente el rendimiento óptico y la relación de concentración del dispositivo, evidenciando que, a mayor área de concentración, mayor rendimiento del equipo.
