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 .
