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.
In the winter, most of the sun comes at midday, so your panels should be pointed directly at the sun at that time. If you adjust the tilt of your panels, it is best to do this four times a year, when the solar season changes. Winter October 13 to February 27; Spring February 27 to April 20; Summer April 20 to August 22; Autumn August 22 to October 13.
