Solar panels should always face true south if you are in the northern hemisphere, or true north if you are in the southern hemisphere. True north is not the same as magnetic north. If you are using a compass to orient your panels, you need to correct for the difference, which varies from place to place.
The solar gain depends on the solar panel direction, angle and of course the time of the year. Find out why and how! As you are aware, the sun rises from the east and sets in the west. During the regular tracking though, the sun moves towards the north, making north the best face to maximise your solar gain.
