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 tilt and direction of solar panels needs to be optimised. When solar energy systems are installed, the tilt and direction of the panels should be optimised to generate the most electricity possible over the course of a year. This calculation is influenced by the time of day, the season and the latitude.
