Thanks for the comments! I wasn't aware that there are only a handful of Solar MD installers. We have limited options for installers in the area and I just wanted to make sure I am heading in the right direction.
It is not supposed to be an off grid system, so won't mind (for now) if I need Eskom for a few hours per day or few cloudy days. I will not connect the aircons and oven to the solar system.
