3. Experimental Setup
For the analysis, the BIPVT collectors were tested two types of the experiment. One is the BIPVT
collector side, and the other is the system side of the AHU with BIPVT collectors. First, the performance
of BIPVT collector was compared with BIPV system. Then the energy saving of AHU system with
BIPVT collector was investigated. The experiment was evaluated in Cheonan, Republic of Korea (36.815°
N, 127.114° E).
3.1. BIPVT and BIPV system
In order to analyze the performance of BIPVT collector, BIPV system was made as shown in figure
3. BIPV system was composed by attaching the insulation behind the PV module to meet the
performance of the building exterior wall. The temperature of the PV module was measured by
thermocouples and temperature characteristics of the BIPVT and BIPV system was analyzed.
