Your family have a small house in the countryside which is not connected to the grid. The place enjoys 3.5 equivalent sun hours. Therefore, you have decided to install an off-grid PV system in the house to supply their electricity. you will be using PV modules with the following specifications: Pnom = 100 Wp, Vmpp =16 V, IMpp = 6.25 A, Voc = 18 V, Isc = 7 A. We may assume that the combined efficiency of the cables, the charge controller and the battery system is 90% and that of the inverter is 96%. As the house is only used at the weekend, only two days of autonomy will be needed. In this case, batteries with the following specifications will be used: capacity 100 Ah, voltage 12 V, maximum allowed depth of discharge 50%. The daily house electricity requirements are summarized in the Table. Load Quantity Power per item (W) Time of use (h) Туре DC Light bulb TV 10 20 1. Calculate the total daily electricity demand in Wh. 1 100 AC DVD 1 40 AC 2. What is the total power demanded by the DC loads? Laptop 1 100 2 AC 3. What is the total power demanded by the AC loads?
