This question has four pieces of information that are needed to answer all questions in this quiz. (Take your time! Read the questions carefully!) Here is the situation: a PV module has been constructed by connecting 36 solar cells in series! Each cell in this module has the following four (4) characteristics: 1) Open Circuit Voltage = 0.60 V; 2) Short Circuit Current = 5.4 A; 3) Peak Power Voltage = 0.50 V; 4) Peak Power Current = 5.0 A. Now, here is question 1: Calculate the Open Circuit Voltage for the module.
A. 21.6 V
B 3.24 V
C 27.0 V
D 18.0 V
E 0.15 V
F 180.0 V
