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-
