people forget this, and this is the reason solar is no longer viable to install now in Victoria as the tariffs they pay you for electricity produced is hardly anything on new system installations
I, for one , am aware of that which is why we haven't had a system installed because I procrastinated when the NSW rebate was still worth something .
The flip side is now the systems are a lot cheaper, our elec bill is double what it used to be (now 2K per year) , so even if we forked out 6K for a system and only halved our bill we would still break even in 6 years
