Here many have solar thermal systems, that is solar thermal system, meaning solar panels for hot water on the east side. We do too, by the way (I have also seen west somewhere). Because sometimes there is no other way, and hardly anyone will orient their house for this obligation. Savings are not really worth mentioning now. However: if it should be photovoltaics, then I would probably only install it on the south roof. Because in that case the surplus is sold.
