What is the disadvantage to tracking with a passive tracker compared to an active tracker?
 
  What will be an ideal response?

Question 2

Explain how the latitude affects the optimum orientation angle of a flat-plate collector.
 
  What will be an ideal response?

Answer to Question 1

A passive tracker loses an hour or so in the morning, while it resets from the previous day. An active tracker does not lose this time.

Answer to Question 2

The latitude determines the sun's path; at the equator, the collector will ideally be horizontal when the sun is at the equinox. At latitudes further from the equator, the angle must be tilted to orient the collector toward the sun.
