A household has a yearly electrical energy usage of approximately 5,000kWh per year. They want a PV grid system that will produce this total amount of electrical energy at the AC switchboard every year. The average temperature of the ambient is 22 °C, and the fairt. =0.92 for the location. The inverter efficiency is 90% with a maximum cable loss of 3.5%, the module to be installed is 180w SilexSolar with manufacture tolerance of +-3% and a temperature de-rating coefficient of 0.5%. The PV panels will be installed in Melbourne facing north and tilted at 30 degree from the ground. Determine: a) The number of PV modules required. b) If the electricity demand in January for this household is double the average electricity used in a hot day, what would be the minimum requirement for the battery capacity if this household does not want to rely on the grid. c) The amount of brown coal (kg) saved if the power station has an efficiency of 30%.
