Abstract: Due to the lower cost and compact structure, Photovoltaic Integrated Collector Storage Water heater combined (PV– ICSSWH) is an alternative form of PV/T system that differs from traditional flat-plate or vacuum tube PV/T system. An analysis was carried out to investigate the effect of operating parameters and structural factors on system performance. A numerical model was developed to predict the performance of the systems. To validate the numerical model, a prototype system was built and tested. The influence of solar radiation, ambient temperature, the thickness of systems, and the aspect ratio of systems was analyzed and the results indicate that: (a) The aspect ratio has a negligible effect on the efficiency. However, it has a significant influence on temperature stratification. (b) As the thickness of the system drops from 100 mm to 60 mm, its total efficiency descents from 55.1% to 52.7% and the relationship is given. (c) The total efficiency only decreases from 54.7% to 53.5%, when the solar radiation rises from 400W/m2 to 800W/m2. (d) As the ambient temperature increases from 283K to 303K, the total efficiency of the system ascends from 45.6% to 61.4%. (e) The total efficiency is about 48.0% in Lanzhou, China which is predicted.
