Problem 1
Imagine that you have decided to relocate to one of 4 cities:
Raleigh, NC,San Diego, CA, Indianapolis, IN, or Tucson, AZ. Assume
that your household annual demand is 3600 kWh. The tables on the
back below give the solar irradiance data for each city in
kWh/m2/day. You want to purchase a photovoltaic (solar generation)
system to supply your household. Which city should you move to if...
