We are thinking about getting that done, and I’ve read there is a government grant of $1000 available for anyone planning to undertake this.

But what is the entire job going to cost me, does anyone know?

It would be for a three-bedroom house, single storey, on a hill.

$1000 + 385 (tank & thermostat) + 1900 for panels + 95 an hour to hook up. Plan to set aside 200 per year to adjust the thermostat and solar transformer.
