To what degree can a solar collector face east or west of true south with minimal effect on its performance?
  1. 90 degrees
  2. 70 degrees
  3. 45 degrees
  4. 30 degrees
Explanation
Answer: A - A solar collector can face as much as 90 degrees east or west of true south with minimal effect on its performance, based upon site location and the degree of collector tilt. However, elements that can affect the amount of sunlight reaching the collectors, such as shade and cloud cover, may drive the need for an orientation closer to true south for maximum performance.
