Question

A higher power PV panel is created by connecting many smaller PV cells in shunt and series as illustrated below. For this problem, the panel must produce at least 60 watts and 12 volts when loaded with an optimum resistance.

a) What is the minimum number of these smaller PV devices necessary for this panel?
b) The panel is formed by connecting M devices in series to form one column and then N columns in shunt. What are M and N?
c) What optimum resistance load should be connected to the panel?
d) If the load resistance is disconnected (open circuited) what is the open circuit voltage?

M X N size panel
