b. Nicosia is located in the center of the island of Cyprus at a latitude 35o10N and a longitude of 33o25E. Household daily load profile is shown in Figure 1. By considering peak solar insolation (PSI) of 1000 W/m2 , DC system voltage of 24V and photovoltaic components specification provided in Table 1, determine: (15 marks, C4) i. Photovoltaic array size and total number of photovoltaic panels in series and parallel configuration.
