Summary

The goal of this paper was to inform about the development of the building integrated photo voltaic thermal (PV-T) system and evaluate its performance in compared to PV installation built of same photovoltaic cells. The study was collaboration among the Technical University of Denmark (DTU and Danish company RAcell (end-reference to website). This project was applied and optimized with the coupled house system on FOLD house, built in purpose of international student competition Solar Decathlon Europe 2012 held in Madrid in September 2012. The proposed PVT system was awarded with first price in Solar system integration sub-contest, during the competition SDE 2012. "Highly effective and innovative integration of PV and thermal systems that is not only a machine added to a house, but added value without creating too much attention to that machinery," said one of the jury members about the PVT system, announcing the winner. The PV-T is a hybrid system where the significant growth of efficiency of electricity generation is caused by cooling the cells to optimal temperature by system of embedded pipes on the backside of photovoltaic panels. The thermal part removes the heat, cools down the cells and increases its el. production up to 14,8% according to PV system using the same cells in the same weather conditions. New solution was carried out for piping connection between panels. The house integrated PV-T system was compared with separate Photovoltaic and Thermal systems from energy and economy point of view. For annual usage of the FOLD house in Spain and Denmark was the PV-T system found as a more beneficial in compare to two separate systems.
