Answer to Question 1

The tilt of the earth's axis causes the difference. When the sun is at its maximum elevation in the northern hemisphere, it is at its lowest elevation in the southern hemisphere and vice-versa.

Answer to Question 2

Answers depend on student location. The optimum angle for a non-adjustable flat plate is generally at the latitude angle from the horizontal but can be set steeper to optimize solar input for winter or flatter to optimize solar input for summer.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
