A house has the following electrical appliance usage: Four 60W incandescent lamp used during 3 hours per day. one 100W refrigerator that runs during 24 hours a day with the compressor turned on half of the time. The standalone PV system is planned. The system will be powered by 12V, 120W PV panels. 1) Find the energy demands per day. 2) Find the number of the required PV panels. 3) Find the size of the required inverter. 4) 12V batteries will be used, considering an efficiency of 80 percent and a depth of discharge of DOD of 60 percent. Find the Ampere hours required to ensure three days of autonomy.
