This.We are inching towards a scenario where an Inverter and Panels will not be considered as backup power only, but as a prudent economical decision to manage runaway power costs, for both domestic and commercial customers..
Same, front loading for cheap to avoid paying more when consumption spikes...I've been loading my prepaid meter up every month with the cheaper 600 unit blocks as I've hardly been using much Eskom power lately. Have over 2000 units now which will be handy for winter.
Just some napkin maths based on some crud assumptions.
R3/kWh x 1,000 units a month x 12 months = R36,000 a year.
A R200,000 system with 4 batteries will pay itself off after 5.5 years. You should then get about 10 years of free power before you need to start replacing things.
This also keeps dropping as they keep increasing prices. 2 years ago the payback period was around 7 years when using a unit price of R2.40...
This just kicks my urge to double battery capacity up a level.
According to my calcs, for me this means 0-600kWh will be R2.4544/kWh and > 600kWh will be R3,8758/kWh
Luckily these days I don't hit that second tier. It's ridiculous.
Yes that right if you normally use under 600 then you should buy 1422 this month, then nothing until you run out.
If you normally use over 600 then fill up as much as you feel safe doing, then make sure you keep buygin R1603 each month after 1st April 2024
