a) We can connect the PV modules in series or in parallel, therefore, to achieve V, we must connect 8 such modules in series:
This is not too much because this result lies within allowable voltage range of "\\pm10\\%" of the nominal voltage. Higher is better than lower.
The current that such an arrangement can produce is
This is the maximum current. A PV module generates voltage. Depending on the resistance of the load, the current vary between 0 and 2.4 A.
b) When each module conducts 2 A, the power in each module is
The power of all 8 modules is
c) The number of cells in a single module:
