Well its hopefully changing. I think that a energy economy is a good thing.
It will never change in SA, the haves will have to fork out more and more for the havenots. What is an energy economy? Seems like 1 of the DA socialist buzzwords to make screwing the rate payer glamourous, like their "social green economy" concept.

So like on a hot day every solar panel in the country will be earning money generating electricity but the grid wont actually need that electricity.

Not quite true, inverters stop drawing power from solar panels when there is no demand for it, solar users see this when their batteries become full and the solar output drops to meet household demand, assuming their is excess solar. If the grid is taking power from solar panels, then it means someone on the grid needs the electricity. The issue for eskom is would it be a cheaper cost to pay you for the solar power or for them to use the power plant to meet demand.


South australia looking to remotely shutdown inverters to prevent grid instability from over supply AND paying consumers producing solar.

100% correct

Here is ours batteries topped up and just matching demand the rest of the day

also cold sunny days are better for production than hot sunny days but thats not the point here
