Assume a 2 A solar cell produces 0.5 V. If a total of 18 V and 4 A is needed, what is the minimum number of solar cells required and how must they be connected?

What will be an ideal response?

Question 2

How would you triple the current capacity of the PV cell array in Problem 5, keeping the same voltage?

What will be an ideal response?

Answer to Question 1

Number of cells in series to produce 18 V = 18 V / 0.5 V = 36 cells in series

Number of 36 series cell groups that are in parallel to produce 4A = 4 A / 2 A = 2 sets of 36 series cells in parallel

Total = 2(36) = 72 cells

Answer to Question 2

Triple the total number of modular by adding 14 more parallel modules for a total of 21 modules.
