Abstract
Actualmente, las células fotovoltaicas (PV) presentan eficiencias eléctricas entre un 5–25%. Uno de los parámetros más importantes que afectan a dicha eficiencia es la temperatura de sus células: mayor temperatura, peor eficiencia eléctrica. La tecnología fotovoltaica/térmica (PV/T) es una solución para garantizar una adecuada conversión de la energía solar. La tecnología PV/T genera energía eléctrica y térmica simultáneamente. Es adecuada para aplicaciones a baja temperatura (25–40oC). Además se reduce el área total con respecto a colectores individuales y la eficiencia global es mayor. Se describe la instalación en una vivienda unifamiliar donde los colectores PV/T se integran con una fuente de calor geotérmica y con una bomba de calor para producir agua caliente sanitaria y calefacción. Este trabajo tiene dos objetivos. Primero, se analizan las posibilidades de la tecnología PV/T. Segundo, // Currently, the electrical efficiency of photovoltaic (PV) solar cells ranges between 5–25% One of the most important parameters that affects the electrical efficiency of a PV collector is the temperature of its cells: the higher temperature, the lower is the efficiency Photovoltaic/thermal (PV/T) technology is a potential solution to ensure an acceptable solar energy conversion The PV/T technology produces both electrical and thermal energy simultaneously It is suitable for low temperature applications (25–40 o C) and overall efficiency increases compared to individual collectors This paper describes an installation in a single-family house where PV/T collectors are coupled with a ground heat exchanger and a heat pump for domestic hot water and space heating purposes The aim of this work is twofold First, the features of the PV/T technology are analyzed Second, a model of a flat-plate PV/T water collector was developed in TRNSYS in order to analyze collectors performance.
