You are to size a stand-alone PV system near Perth to deliver 4 kWh/day at a peak ac demand of 2 kW. You plan to run everything in the house on 240 Vac provided by a 90% efficient inverter. Insolation data on a North-facing flat panel inclined at latitude angle, and mean temperatures are shown in the table below. Location Month Jan Feb Mar Apr Ma Radiation 8.1 7.7 6.7 5.0 4.0 (kWh/ m²-day) 1560 Perth, WA: 32°S, 116°E Jun July Au 1(c) Min. Temp. 18. 18. 1 (°C) Max. Temp 31. 31. 29. 25. 22.5 19.

Pick an appropriate system voltage to avoid currents greater than 100 A. b. Size the battery bank such that 95% system availability will be provided. Use 12 V, 460 Ah, deep-discharge lead-acid batteries. The batteries have a Coulomb efficiency of 95%. c. Size the PV array. Use 120 W modules with rated current 7 A and rated voltage 17 V. Modules have an NOCT of 43°C and the maximum power drops by 0.3%/°C. There is a 4% array loss due to mismatched modules and dirt loss is 3%. d. Draw the system "wiring" diagram showing series/parallel combinations of the PV modules and batteries. e. If PV modules cost $300 each, batteries cost $200 each, the inverter costs $1/W and the system is paid for with a 20-year, 6% loan, what would be the first year cost of electricity? Ignore any tax implications. You are to size a stand-alone PV system near Perth to deliver 4 kWh/day at a peak ac demand of 2 kW.
