Figure 4: Daily Temperature characteristics of PV DSF (summer) Figure 5: Daily Temperature characteristics of PV DSF (winter) Temperature characteristics comparison Figs. 6 and 7 present temperature comparisons for the cavity and the external wall of the two models for three specific days in summer and winter. For both seasons, the PV DSF model had a lower cavity temperature than the Glass DSF model. From the simulation results, it was found that a maximum difference in cavity temperature of 1.51°C in summer and 1.17°C in winter, which translates to the DSF model having slightly higher temperatures. This is because the reduced so- 608 ZEMCH 2015 | International Conference | Bari - Lecce, Italy
