So, looking at prices for both, including installation, it seems like six of one and half a dozen of the other. What to do?

Yes. R12k -ish for gas vs R16k-is for a 150l split solar installed system. When you look at the total cost of ownership in relation to a 20 year bonded property, it's almost the same price for me.
 
Those of you who have solar geysers - what if you want a hot shower at 5am - is there hot water still? Or is the geyser supplemented with grid when there is no PV power?

you will save way more than R4k on electricity costs in 20 years with a solar geyser, also, gas isnt free

PV = photovoltaic.

The geyser should still be warm from the previous day. If not, there's an element that you should probably control with a geyserwise or similar.
Or like me, you have a gas boost.

16k sounds way too low from what I've seen in the past.

/edit I see prices have come waaaaay down. A couple of years ago these systems were around the 30k mark.
 
For the absolute best of both worlds
200ltr solar geyser -> Rinnai gas geyser -> taps
https://rinnai-gas-geysers.co.za/ these are the best IMO
I got a Suntank 200l geyser and very happy with it. It feeds the bath rooms and gas geyser kitchen. With solar geyser you don't want continious draing of hot water by the domestic in the kitchen during the day.
 
We had this decision when we renovated our house before moving in but went gas since we needed two separate geysers, were going for a gas stove top and were looking at a built in gas braai. If I remember correctly, we paid around R35k for the two geysers, one is a 5l fixed flow rate and the other a 16l variable rate, all piping, valves, fittings, dual 48kg gas cylinder cage, two 48kg filled gas bottles and gas COC. A single solar geyser obviously wasn't as much as the gas installation although it was still expensive but we were putting gas in anyway, so the solar didn't make practical or financial sense for us.
 
I have solar Geyser with a geyserwise I did not want gas, during summer the water is HOT...In the afternoon the water is above 60...This is the current In summer it gets extreme...I wanted a once off cost.

See, that was my thinking, we already have a full gas installation for the stove. Was hoping to simply add to that for a geyser.

If the water is too cold, you can manually heat it up if you have a Geyserwise. If 5am is the time you usually get up you should probably have set the timer from 04:30 to 05:00 to heat the water up in case it fell below your preset threshold temperature. Mine is 55 degrees celcius.

Seeing that you mentioned the summer season, how is the geyser faring in icy cold conditions?

The highest I've ever seen mine go was 78 and I was legitemately worried that the water might start boiling in the damn thing :ROFL:
