How would you change the system in Example 4-3 to provide four days of autonomy using the same batteries?
 
  What will be an ideal response?

Question 2

How many degrees per day does the sun move along the ecliptic?
 
  What will be an ideal response?

Answer to Question 1

To achieve four days of autonomy, three more banks of four series batteries are added to the system, for a total of 24 batteries.

Answer to Question 2

The sun makes one trip around the ecliptic in 365.25 d. Therefore each day it travels 0.986 degrees.
