Hi AVB,
The systems are heavily subsidised by the government in their aims for zero emissions by whenever, without it they shoot up in price. I was talking to a friend who paid not a cent to have his 18 panel system fitted, apparently the energy company sort of lease your roof for 10 years and they do this to a number of houses in close proximity and they are then able to use this as a small power plant. He doesn't get any feed in tariff but it has reduced his power bill to about $100 for 3 months which is about the supply charge only he is paying for. After 10 years the system becomes his. Now that was a good deal
