Does roof orientation matter?

In Adelaide orienting your panels to face north at an incline of between 25 and 30 degrees is best. As a general rule panels that face due west lose about 10% of their generating capacity and panels that face east lose about 12% of their generating capacity, however the exact results depend on the incline on the panels.
