Below is a table that lists major U.S. cities and their available sun-hours.
a. How much electricity does a 4-KW solar PV system in Chicago generate in a year?
b. How large would a PV system need to be in Fairbanks, New York City, and Miami to generate the same amount of electricity in a year as a 2-KW system in Phoenix?
c. Miami is further south than Phoenix, so in principle it should have more sunhours per year than Phoenix. What are some reasons why it does not?
What will be an ideal response?
a. 4kW x 3.14 sun-hours x 365 days = 4,584.4 kWh per year
b. Using the same equation as in (a), the Phoenix system generates 4,803.4 kWh/yr. Using the same equation as in (a) and solving for X, where X represents the size of the system:
c. The basic reason is weather and climate. Southern Florida gets more rain than Phoenix (a semi-arid climate) because it is a coastal climate and also experiences seasonal hurricanes.
