There are excellent instructions on the site below for calculating your
declination and true, as opposed to magnetic north, using a chart from the
guvmint:

You'll need to know your latitude and longitude.

While true south is best for solar collection, other orientations might work
better for you, all things considered. The advice I've seen is that locating
within 20 degrees east or west of true south doesn't lose much solar
capacity if view, shading trees or buildings, p.m. heat or a.m. light, etc.,
are concerns.
