You live in a city whose latitude is 50º and wants to build a system of water heating by solar radiation
.
a )if you want more heat in early winter (winter solstice), which angle the surface of the solar collector must make with the horizontal?
b) what is the angle if you want more warming in early summer?
c) What would be the angle that in the annual average the heating is more efficient?
