If you built in on Antarctica - specifically: right on the south pole - then you'd need to angle it toward the horizon, since that's where the sun would be, and have it rotate once per day (thus tracking the sun). This of course means that it will always be facing north no matter which direction it faces.
Oh, and this would only work in SH summer, since in SH winter the sun would be below the horizon.
Of course, relying on solar energy at either of the Earth's poles is largely futile ... I was just trying to add a different answer...
