Fig. 3 presents the PV cells temperature for the three configurations studied for a sunny winter and summer day in Yellowknife with leeward wind. As it can be observed, the PV cells temperature in configuration A and B are very close since the PV laminate replaces the outer pane in both cases. For the winter day, the maximum PV cells temperature difference between configuration C and configuration A or B is of approximately 12oC during daytime. For the summer day, this difference is of about 16oC. The DC electrical power produced by the PV cells for these 2 days is presented in Fig. 4. The graphs reveal that the power generated by configurations A and B is very similar, but at peak sunshine hour, approximately 14% and 20% greater than configuration C for the winter and summer day, respectively. This can be explained by the higher cells temperature and the fact that less radiation strikes the PV cells in this configuration because of the outer glazing layer reflecting and absorbing part of the incident solar radiation.
