Bloody solar salesmen.
$4k rebates for 5kw system? Ours are just over $3k here in Vic. From what I here, down here the feed in stays with the property, so doesn't matter who's name is on the bill. Didn't know that about the inverter upgrade though, I am a little out of the solar loop these days, after 300+ installs, I really can't stand doing it, and dealing with solar people (no offence), they're no different to used car salesman (unless its the tradesman, they are the only smart ones)
