You have been commissioned to design a stand]alone solar PV system (solar panels + battery array) for a 1000ft2 occupied between May through October, off]line cottage located near Corpus Cristi, Texas. The PV array should supply the daily average requirement of 7.2 kWh and could be mounted on the south]facing sloping roof at any required angle (which should be determined). Determine the required battery array sizes. State clearly all assumptions. (You can find solar data in the Solar Radiation Data Manual for Flat]Plate and Concentrating Collectors)
