Influence of Triangle-Shaped Obstacles on the Energy and Exergy Performance of an Air-Cooled Photovoltaic Thermal (PVT) Collector

A photovoltaic thermal (PVT) collector is a type of solar that can simultaneously produce electrical and energy from energy. In this research, the daily annual performances an air-cooled PVT with triangle-shaped obstacles were investigated compared those conventional collector. Based on circuit model, numerical model containing has been developed validated using experimental results. typical meteorological year’s weather data Ulsan, Korea was used as data. From results, it seen average thermal, electrical, overall exergy efficiencies for 24.73%, 15.59%, 62.83%, 15.57%, respectively, while values 17.08%, 15.30%, 54.47%, 15.13%, respectively. The results also showed outputs 12.84% 1.98% greater than these clearly confirmed enhance
