摘要：
An investigation on PVT-PCM/water system has been carried out under the weather conditions at Kottayam (9.5425 degrees N, 76.8202 degrees E), India. In the present paper, experimentations have been done to compare the overall performance of PV and water-based PVT-PCM panels. The PVT-PCM/water system has been analysed under various outdoor environmental conditions and it has been recorded that the integration of PCM contributed to an improved thermal and overall efficiency of 26.87% and 40.59% respectively, along with a rise in electrical efficiency by 17.33% compared with conventional PV panel. It has been found that the payback time for the water-based PVT-PCM system is about 6 years on the overall exergy basis, which is 11.26% shorter compared to conventional PV panels. Also, the water-based PVT-PCM system has long-term lifecycle conversion efficiency compared to conventional PV panel by about 27%.
