Estimated solar monthly saving

You can see on my attached note my geyser seem to be the definite savings winner, The geyser was R15k the smallest layout cost but with the biggest benefit of about R766 per month

Nice one Gerrie! I put 2 x 250l in series (because I often have guests). And I agree with you. It’s the first thing I tell people when they ask me about my installation.

Thats quite a bit of free hot water, your monthly saving must be way over R1000 per month if you make use of it. 

If only Eskom looked into subsidizing solar geysers again it might stabilize the grid. But reduce revenue that they will try avoid at all cost.

I haven't done the sums, but i reckon it must be between R500-R1000 depending on how many guests I have during the month. Not to mention extra available hot water, on days when its cold. We also experience very cold winters here (southern Drakensberg - not uncommon to see temps 2 to -10 c on winter mornings @ 1500m above sea level) Being connected in series, means the one I draw from, is always being filled with hot water (or at least warm) from the other one. I also have an element in the one I draw from - just in case (my wife severely warned me that if we ever ran out of hot water....😁)

To be honest - I don't think the political powers that be are ever going to let that happen, even with Andre de Ruyter at the helm

Technically, it was the Department of Energy that did it, or provided the funding, Eskom just managed it.

Read about areas outside of South Africa where there is a high take up of solar power. It causes problems. I've had the municipality sniffing around my place, and I don't really blame them. They are now making very little money out of me but still bear the cost of providing a connection to my house. And this is one of the problems: Short term lots of solar power and solar geysers reduce load, but long term they reduce income but you still have the same infrastructure to maintain.

OK... there is an alternative explanation in this country, but Eskom and municipalities can argue the same principle and it would be valid.
