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 Light bulb TV Time of use (h) Quantity 10 1 Power per item (W) 20 Туре DC 1. Calculate the total daily electricity demand in Wh. 2. What is the total power demanded by the DC loads? 3. What is the total power demanded by the AC loads? 4. How much energy in Wh must the panels generate in one day to cover the daily electricity demand of the family? 5. Assume the panels work under MPP conditions. How many panels will be needed to produce that energy? 6. The system is designed to use 24 V as its operating voltage. What will be the minimum battery capacity required in 100 AC DVD 1 40 100 AC Laptop 1 AC Ah? 7. How many of the specified batteries will be needed?

Nodal Analysis

In the analysis of any electric circuit, nodal analysis is the method of determining the potential difference or voltage between different nodes in an electric circuit. A node is a point where two or more branches connect each other. In the nodal analysis, the voltages are determined in the terms of branch currents. The nodal analysis is also known as the node voltage method or branch current method. The nodal analysis method is one of the several applications of Kirchhoff's Current Law (KCL).
