Extracted text: B2 (i) A PV system is using 74 W, 12 V panels and 6 V, 165 Ah batteries in a good sunshine area. The battery efficiency is 80% and the depth of discharge is 78%. If, in wintertime, there are 5 h of daylight, estimate the number of PV panels and batteries required for a 24 V application with a load of 2400 Wh. No of PV panel required = Storage required = No of Batteries= B2 (ii) Which type of PV system is independent of Grid? Explain the operation with neat diagram?.
