Design a solar PV system for a rooftop mounted system for the loads, whose details are given in Table 1. The minimum sunshine hours may be assumed as 5 hrs. Select a 24V DC as the system voltage. Given: Solar PV panel to be used are: Wp = 80 W, Vm = 17.6 V, Im = 4.55 A Operating factor = 0.8 Battery efficiency = 85% Inverter efficiency = 95% Charge controller efficiency = 95% Days of autonomy = 1 Use PV module: "BP380" from BP Solar, whose data are given below: Peak power = 80 Wp Voltage at peak power (Vpp) = 17.6 V Current at peak power ((Ipp) = 4.55 A Assume operating factor of 0.8 CFL Fan TV Load PV array Table 1: Rooftop mounted solar PV system load details Rating Power (Watts) (Watts) 15 75 75 300 100 100 250 250 150 150 875 Es Computer Refrigerator Total Assume the following Energy flow diagram: Number Charge controller n = 95% 5 4 1 1 Ec 1 Battery n = 85% Energy flow diagram Hours/day 4 3 3 2 12 Inverter n = 95% EL Wh 300 900 300 500 1800 3800 Load
