Question

Power system problem. Please show all steps and make the solution clear

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 your priority is minimizing the total area of this system? Assume that the PV system will be mounted at the Lat-15 setting (ie. use the first row of each table to read the irradiance of each city) and have an efficiency of 25%.
