New fees and tariffs for 2022 have been published, and it seems that Cape Town has finally realised that Solar is not the enemy, and is in fact a good thing. Residential solar falls under what the council calls Small Scale Energy Generation or SSEG.
The new tariffs have removed the onerous daily SSEG fees, and now seem to actually make a mild amount of sense to feed back to the grid. I suspect that they are keen to have people feed back now. City of Cape Town (CoCT) can make a profit on reselling cheaper power, and it will help to reduce load-shedding. Oh, and it will also reduce pollution. Win-win!
The Tesla PowerWall is finally becoming available in South Africa, so I thought I’d do some “30% for math” calculations to work out payback periods.
This post is mostly inspired by the comments here – http://mybroadband.co.za/news/energy/154888-here-are-the-tesla-powerwall-systems-you-can-buy-in-south-africa.html
Thanks to MacAfrican for the criticism in my comments, otherwise I’d be too lazy to do this post 🙂
Onto the math –
Predicted cost at the moment for a daily use PowerWall is $4000.
Rand is currently hovering at R16 (lets hope Zuma doesn’t open his mouth in the near future, as that historically has lead to large drops in Rand values).
