I have no idea how to do this problem:

Design an array of individual solar cells that woulproduce 120 volts DC. About how large an area of solar cells would be needed to produce 2 kWe of/ output power at noon on a clear day

Is a start.

The actual connections, and voltage regulators, are a little complex.
