LV-17-C050 -- Comparative Performance Evaluation of Transparent and Opaque BIPV/T Collectors: Roof and Facade Integration ✓ Most Recent

Building integrated photovoltaic/thermal (BIPV/T) system provides sustainable solution in design structure as part of the building envelope. TRNSYS opaque and transparent BIPVT types were used to model opaque and transparent BIPV/T systems with a basic single zone house. A modified Type (Type 298) was used in the developed opaque BIPV/T model. A detailed mathematical model of transparent BIPV/T system was developed and implemented as a Type (Type211) in the building energy simulation software. The BIPV/T-house model was used to conduct case studies to evaluate the performance of each collector. Comparative studies were performed between both opaque and transparent BIPV/T systems, each integrated into the façade and roof of the house for Toronto area. The results showed that the thermal efficiency of the transparent collector was significantly higher than that of the opaque collector due to the transmitted solar radiation through the non-packing area. Regarding the effect of collector installation angle and season, it was found that the higher the collector tilt angle in winter and the lower collector angle in summer, the more thermal and electrical energy were produced from the collector.
