4lamp each one 15 watt
3fan each one 40 watt
1TV 80 watt
1refrigerator 120 watt
1p.c 210 watt
And the lamps will work 3 hours, the fans 6 hours, the TV and p.c 4 hours.
Calculate the following:
A.C average daily energy.
D.C energy.
If we will use inverter 1 Kw and 48 volt calculate the ampere hour.
If we will use a module 100 watt and it’s voltage 16 . 17 volt calculate the number of the module for each string .
Draw design of the system.

Calculate the fill factor for asolar cell which has the following parameters:

V[SUB]oc = [/SUB]0.2 volt
I[SUB] s.c = [/SUB]5.5 mA
V[SUB]max = [/SUB]0.125v
I[SUB]max = [/SUB]3mA

Calculate the maximum and cell efficiency of the cell at an intensity of 200 w/m[SUP]2[/SUP] given that V[SUB]o.c [/SUB]= 0.24 volt and I[SUB]s.c = [/SUB]9mA,
V[SUB]max[/SUB] = 0.14 volt, I[SUB]max [/SUB]= 6mA and the area = 4cm[SUP]2[/SUP] .

Calculate the power output from asolar cell under standard test conditions when efficiency = 16% and filling factor = 0.782
And the aperture area = 4.02*10[SUP]4[/SUP] m[SUP]2[/SUP]

Draw the simple single line diagram of pv system in case of :
on grid
off grid

Draw the p.v and the i.v curve of the module.
