Im working on a problem that involves a PV module consisting of 40 cells each at .5 volts. The problem models the module as having all 40 cells in series. The PV module is connected to a 5 ohm load. The problem also says to assume that the same current and voltage flows through the PV module and load. So solve for I, V, and P. I just need to find the current, power, and voltage for 3 conditions. a) when in full sunlight b) when 1 cell is in shade c) when 2 cells are in shade. my question is: I know the voltage to be 20 volts in full sunlight and 19.5 volts when 1 cell is in shade....so when 1 cell is in shade I noticed the book saying that one .5 volt cell will now act as a 5 ohm reisistor.....is this true....and why? and if that is the case for 1 cell in the shade would I have a total of 10 ohms resistance to calculate the current flowing?
