This is actually National (i.e. ANC) policy.Correct, I hate CoCT socialist scum: "the haves will pay for the have-nots until all are equal" - CoCT.
CoCT owns the infrastructure that you are connecting your solar system to. That is why they want you to register. That way they know what is going on. The other municipalities clearly have no idea about this and that is why they don't require registration. If you were suitably qualified (or connected) it would cost you nothing to register your system. CoCT want to know that the system that you want to/have installed meets all the necessary STATUTORY requirements. So these are required by various laws (National and NOT CoCT specific).
The very basic idea behind all these laws are to protect people from getting electrocuted or burning your neighbourhood down. I did not opt for the feed-in option as CoCT does not make it at all attractive; even if they paid for the very expensive meter!
