What kind of batteries do they use for that scale?
They are lithium and each the size of a small container. Lots of them daisy chained together. Capacity of each will no doubt differ between manufacturers, but ours are a bit over 1000KWh each.

I'm used to thinking in Ah due to my little backup system. How do you convert Ah <-> kWh?They are lithium and each the size of a small container. Lots of them daisy chained together. Capacity of each will no doubt differ between manufacturers, but ours are a bit over 1000KWh each.

Google says:No idea. I’m a civil engineer

So 800MWh means 800 of those containers.They are lithium and each the size of a small container. Lots of them daisy chained together. Capacity of each will no doubt differ between manufacturers, but ours are a bit over 1000KWh each.
Google says:
One (Ah) equals the amount of charge (think electrons) moved by a current of one Amp for one hour. ... Watt-Hour (Wh) is a unit of measurement that describes accumulated energy. One Watt-Hour (Wh) is the resulting energy from operating at a power of 1 Watt for 1 hour.

Pics?I visited one of South Africa's biggest PV plants today. 82.5MW at the cost of R5billion to build. Quite a sight it is too.
Fifty would equal one fully functional Medupi.I visited one of South Africa's biggest PV plants today. 82.5MW at the cost of R5billion to build. Quite a sight it is too.

Panels are larger than domestic panels it looks like? Do they track the sun?A couple of pics of the PV plant at Paleisheuvel. It's hard to get an idea of the scale without a fancy lens and a decent angle, but here they are nonetheless

Only question is when, not ifJust one thing needs to break down then we're likely to get shed.
