save me the time and energy please and work out the OCGT kWh cost with your R12 per litre figure?Read the MYPD5 report and use a calculator.

Yep, ordinarily we have no increase in winter consumption but with our son that changed as we run a wall panel heater in his room, temperatures can get in to the negative where we live.
We are also waiting for Mr Powerforum for LFP batteries to replace the LA's![]()
It would serve you well insulating that room.Yep, ordinarily we have no increase in winter consumption but with our son that changed as we run a wall panel heater in his room, temperatures can get in to the negative where we live.

No need. I'm used to it by now./readies the Vaseline
Massive issue with batteries. Hubble seems to have dropped the ball or Steve dropped the ball. Either way the allocation for my install was botched and now I'm sitting without solar. Holding thumbs to get at least one battery in the next 24 hours so we can get up and running again.
Whole week of running up Eksdom bills again.

Si its maybe better to wait for the cheaper and better batteries.15+ years, around 20k per 5kwh battery at today's price. Batteries will evolve, last longer and get cheaper in future - especially with the push towards electric vehicles. But Eskom won't...
Does geyser insulation save a lot?Sooner or later Eskom will get their 20% increase. Do yourselves and your wallets a favour. Get your house and geyser insulated before the increase and get replace all old appliances (fridges, washing machines). It’s an investment now but you won’t be forking out so much on electricity when the increase inevitably happens.
Builder’s sells insulating wool for ceilings and I believe even rock wool panels for walls. You can even get double glazing for windows in the big metro areas especially in Cape Town. It’s an investment now but it’s cheaper than what heating the outside air will cost you in winter after the increase…
I think thick curtains is fine. Mainly in the ceiling I'm talking about.And double glazed windows?
The light pole is starting to look very attractive . . .Eskom wants a 20.5% electricity price hike
Eskom chief financial officer Calib Cassim has confirmed that the state-owned power utility has applied for an electricity price increase of 20.5% for its 2023 financial year, set to take effect from 1 April 2022.
The company confirmed its application following a press statement from the National Energy Regulator of South Africa (Nersa), which Eskom said misrepresented its application.
Engineering friends had solar-based and lightning-proof traffic lights 25+ years ago during discussions with the City. Rolled out to Asian cities for years already at that stage. They couldn't implement because it wasn't through the right "contacts" and if the traffic lights didn't need as much maintenance then the higher-ups' "connections" at the time would lose the revenue from repair work.True that, just because your home has solar and storage does not mean that the rest of SA does, especially things like traffic lights. That is why independent Microgrids are a thing of the near future, watch it take off.
Curtains in the ceiling?I think thick curtains is fine. Mainly in the ceiling I'm talking about.
Lol - I see how that reads. I mean curtains instead of double glazed windows and insulation on the ceiling.Curtains in the ceiling?
A brand new Kwikot geyser has an hourly loss of 50Wh by just being plugged in. This is 1200Wh in a 24 hour period or 1.2kWh/day in losses. At an average of R2.00/kWh you’re looking at losses of R2.40/day or R876/year. Remember this is for a brand new geyser. If you’re geyser is older your losses will be at least twice as high.Does geyser insulation save a lot?
There is no stock of Hubble batteries anywhere. And the stock has an ETA in the middle of December.Massive issue with batteries. Hubble seems to have dropped the ball or Steve dropped the ball.

Not what is causing my problem but thanks forThere is no stock of Hubble batteries anywhere. And the stock has an ETA in the middle of December.
My geyser is still rated in pounds....Got those 110V ceramic elements in . Still working as was bought. Yes Sure new ones are a little more efficient. But quality is a bit on the Low side.A brand new Kwikot geyser has an hourly loss of 50Wh by just being plugged in. This is 1200Wh in a 24 hour period or 1.2kWh/day in losses.

Also these losses do not include the pipe losses that most likely aren’t insulated either.
So if you use a geyser blanket and are able to half the losses then you’ll be saving R1.20/day or R438/year. Last time I checked a geyser blanket on takealot was about R300. So it’s up to you to decide if it’s worth it.
If it were up to me I’d say pick up some pipe insulation while you’re picking up your geyser blanket at Builder’s. It will pay for itself in a year.
And if you haven’t in the last few years, get a new geyser as it’s better insulated and wastes less energy. It will pay for itself in 2-3 years.
