That does change things. I doubt you will have much trouble getting useful
light in Johanessburg. It is probably reasonable to make sure you have a way
of controlling the brightness of the light. I cut a large panel that I could
lay over the tank when I wanted to block out sunlight. Blinds on the
skylights would work, too.

Per day, not much. It comes out to about 1.5 cm/week. That varies with a lot
of factors, including the water temperature and the air humidity. I keep my
tanks fairly cool and during the summer we use evaporative cooling, so the
indoor humidity is high. It's much drier in the winter and the evaporation
rates go up a little.
