Ans. to #1

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.

Ans. to #2

cos 20o = 0.985; therefore less than 2 loss due to non-optimum tilt.

Ans. to #3

40o

I wish all teachers could be as helpful as you instead of making us do things the complicated way...
