what Rads said happens quite a bit as there are only a dozen meter qualified guys to change these smart meters in, so there can be some delays and have to make sure the provider has booked you in
also once you get your panels and smart meter you can see where the power is going - surprising how much goes into the hot water so I did some research and got the Apricus Hot Water System with a SS steel water tank, no noise and hot water - after solar panels I am saving an additional $100 a quarter on hot water, and I think element hot water systems phase out at the end of this year.
