A standalone diesel generator provides night-time warehouse lighting and security lighting for a remote freight storage compound. The lighting load between 6pm and midnight is 9.2 kW when the warehouse and security lighting are both operating and it drops to 3.7 kW between midnight and 6am when the warehouse is closed and only the security lighting is on A. What is the average daily load for this application in kWh/day? (4 Marks) (9.2kW6h)+(3.7kW*6h)= 77.4kWh B. At this facility has a large north facing roof area (with a slope of 20°) and with the reducing cost of photovoltaics, it is proposed that the use of a standalone PV system be investigated for this application. Efficiency data for this problem is as follows Battery energy efficiency is 80.5% The battery Coulombic efficiency is 90% Average inverter efficiency is 86% The average MPPT efficiency is 96.5%. Losses in cabling from the array are 1.5% of the array output Annual solar radiation : 23.1MJ/m2 The characteristics of the PV modules proposed for this task at Standard Testing Conditions are as follows Module Data at STC: Module rated output Short Circuit Current Open Circuit voltage Voltage at Maximum Power Point Current at Maximum Power Point Current at 28V (for module temperature up to 60°C) Temperature coefficient of Pmax Temperature coefficient of Isc Temperature coefficient of Voc Module efficiency 290 W 8.53 A 44,9 V 36.1 V 8.04 A 8.51A 0.44% /°C 0.046%/”C -0.33% °C 14.90% How many modules and batteries would be needed for this system when using the annual average solar radiation?
