I don't have a gas powered generator attached to my house. Therefore, if I put a solar panel on my house, then my property would have a 100% renewable supply of electricity

Unfortunately that solar panel wouldn't meet my house's electricity demand, so I would have to import the difference from my local power company. But that doesn't change the fact that on my property the supply is 100% renewable

> Or exported .. SA actually exports a great deal of peak renewable energy, it over produces in the daylight and uses that to charge a battery farm or to feed to the neighbouring state.

Peak generation hours are almost never aligned with peak demand hours. Unless those battery farms are capable of meeting the supply during their peak demand (very unlikely, I don't think there is any country with this sort of battery capacity built), then they must be re-importing electricity from those same neighbors who are still burning fossil fuels (or have other more consistent power supply like nuclear or hydro)
