Analyze the following simple PV/battery system which includes four PV modules, four batteries and an inverter. The rating of each module is shown in the figure below. The 6-V batteries have 200 Ah capacity with 90% coulomb efficiency. The 85% efficient inverter feed the AC load. There is no maximum power point tracker. a) The insolation is 6.0 kWh/m²-day and the module loss is 15% due to dirt, wiring losses etc. Estimate the kWh/day that would reach the loads. Assume all PV current passes through the batteries before it reaches the inverter. b) If the load demand is 1.2 kWh/day, for how many cloudy days in a row can a previously fully charged batteries supply the load with no further input for PV modules? Assume 80% of their Ah capacity is available.
