Q1. You are required to design a stand-alone solar PV system for a rural home with the following electrical load designed to operate on single phase, 230 V 50 Hz supply. The type of load, the rated power and the number of hours each load is used are as shown in the table1. Table 1 Load Watts Hours Tube light 1 20 6 Tube light 2 20 6 Tube light 3 20 6 Kitchen light 30 10 Fan 1 70 8 Fan 2 70 8 70 10 Fan 3 The data of the solar panel to be used for the design is given in table 2. Table 2 Cells P V MAX MPP MPP Voc Nominal Voltage 36 170 Wp 19.2 V 8.85 A 23.4 V 9.35 A 12 V Assume an average yearly solar insolation of 5 kWh/m per day at the location of rural home. Also assume that the overall efficiency of the system due to all the connected equipment is 70%. (i) List all the major components required for the installation of the PV system. (4 marks) (!!!) (ii) Calculate the daily energy consumption in Watt-hour (Wh). Calculate the number of solar panels required. (5 marks) (5 marks) (iv) Calculate the number of 12 V, 200 Ah batteries required assuming a depth of discharge of 80%. 16 marke)
