A Pilot Study of the Building Integrated Photovoltaic Thermal (BIPVT) Collector for Commercial Applications in Malaysia

摘要

Building integrated photovoltaic thermal solar collector (BIPVT) has been designed to produce both electricity and hot water and later integrated to building. The hot water is produced at the useful temperatures for the applications in Malaysia such as building integrated heating system and domestic hot water system as well as many industrial including agricultural and commercial applications that require low grade heat (>50℃). An experiement study of a BIPVT collector involving a specially designed absorber collector has been performed for heat transfer enhancement. The results of performance and efficiency including the photovoltaic, thermal and also the combination of both are discussed and analyzed. Results at solar irradiance of 904 W/m~2 shows that the combined efficiency of 60 %, electrical efficiency of 11% at mass flow rates of 0.041 kg/s.
