Family Smith has a small house in the country side which is not connected to the grid. The place enjoys 3.5 equivalent sun hours. Therefore, Mr. Smith has decided to install an off-grid PV system in the house to supply their electricity demand. The house electricity needs are summarized in the table below.What is the total energy demand Wh? What is the total power demanded by the DC loads in W? What is the total power demanded by the AC loads in W? ______

Now suppose that the PV module mentioned above is set up using a series connection of solar cells with the above mentioned specifications. Two of the solar cells have gone faulty (completely stop generating power), but fortunately you have bypass diodes connected across the faulty solar cells. Assume that the bypass diodes are ideal (they have a zero voltage drop when conducting).What is the measured open-circuit voltage (in \(V\)) of the above PV module with the faulty solar cells? ______
A given monocrystalline silicon solar cell has the following specifications:\(I_{sc} = 5A\)\(V_{oc} = 0.6V\)72 identical cells with the above specifications are to be interconnected to create a PV module. What is the open-circuit voltage (in \(V\)) of the PV module if all the solar cells are connected in a series configuration? ______
