It's not economically viable.

My friend got a quot for solar hot water system, $10000, for a solar-gas boiler. It is not worth it.

The solar panels are very expensive, and the installation is even more expensive. If you are not live in the middle of a dessert, you will still need to hook to the grid.

It is viable for some Australian's, who live in the middle of nowhere. Because they have to pay a huge sum for the national grid's infrastructure.

The technology is just not there yet. When solar powered cars are running around on the street, that's the time you could think about solar system in your house.
