This study evaluates the thermal and electrical performance of roofless building-integrated photovoltaic and thermal (BIPVT) systems, focusing on three liquid collector systems. A full-scale mock-up simulating a curtain wall structure was developed to test these systems. The three BIPVT configurations are as follows Case (2) incorporates manifolds and plate heat pipes in contact with the tubes, and Case (3) uses manifolds and plate heat pipes in direct contact through a perforated structure. The thermal efficiencies ranged from 21.2% to 32% for Case (1), 7.6% to 13.6% for Case (2), and 3.7% to 9.4% for Case (3). The combined efficiency, including electrical power, was highest for Case (1) at 34.8%, followed by Case (2) at 19.8% and Case (3) at 17.2%. These results indicate that Case (1) provided the most effective heat collection and power generation, attributed to the larger heat transfer area of the absorber mechanism compared to the heat pipe. Overall, this study demonstrates that BIPVT systems, especially Case (1), offer significant potential for improving the energy efficiency of buildings. However, Case (2) provides advantages for building integration by eliminating the panel-to-panel joints on the building facade, which significantly reduces the risk of leakage. Case (2) is also a viable option for enhancing energy efficiency in buildings, particularly in terms of long-term structural integrity and maintenance.
