Centrales fotovoltaicas a 1.500 V

Centrales fotovoltaicas a 1.500 V

Abstract

Una alternativa para reducir el coste de la electricidad fotovoltaica, que está muy en boga en la actualidad, consiste en subir la tensión del lado de CC de los generadores desde 1.000 V, que es el límite estándar de las centrales actuales, hasta 1.500 V. Este artículo analiza el impacto tecnológico y económico de esta subida de tensión. Para lo primero, recopila las exigencias de la normativa vigente y ensaya la resistencia de aislamiento y la resistencia al PID de una muestra de módulos representativos de la tecnología actual. Para lo segundo, estudia la reducción de materiales en la construcción de los generadores. Concluye que los módulos actuales de silicio cristalino son capaces de trabajar a la nueva tensión sin más que algunas ligeras modificaciones constructivas, y cifra la reducción esperable de costes entre un 2 y un 3%. Este estudio fue el Trabajo Fin de Master del primer autor para el Master en Energía Solar Fotovoltaica 2015-2016, impartido por el Instituto de Energía Solar de la Universidad Politécnica de Madrid. El segundo autor fue su tutor. Los ensayos se han llevado a cabo en la sede que el IES-UPM tiene en el Campus Sur (Vallecas), España, entre los meses de febrero y abril de 2016.
