Figure 3: Daily Temperature characteristics of Glass DSF( winter)
Figs. 4 and 5 show the daily temperature characteristics of the PV DSF model in summer and winter, respectively. From the results for the PV DSF model in Fig. 4, the external wall has the highest temperature at 41.54 ° C, followed by the cavity at 34.38 ° C, which is 6 ° C higher than the external temperature. In Fig. 5, the maximum temperature of the cavity is 13.79 ° C, or 8 ° C higher than the external temperature. Temperatures of both the external wall and cavity for the PV DSF, compared to the DSF, were lower by 2 ° C or less. Despite the low solar radiation in summer, the back insulation conditions caused the PV temperature to rise to approximately 40 ° C. In winter, the PV temperature was similar to that of the summer even with the significantly higher amount of solar radiation. This indicates that the integration of PV in building facades allows greater gain of solar radiation and reduces the PV temperature rise.
