At present, there are only 30% of homes and offices in Canberra that would be able to take any advantage of solar panels, in any event (from Actew).

Toasters are a very poor basis of comparison. They're only in use for 
minutes at a time rather than hours. Something that will "only" power 
100 toasters will power thousands of low-power lamps.

The chief criminals of power waste are:
- heating elements
- flat panel TVs
- inefficient refrigeration (eg, use a chest freezer rather than an upright)
- water pumps (only relevant if you're using tank water)

Every other necessity can be powered from solar with no problems.

With a grid-connected system, of course, the occasional excess (from the 
toasters, for eg) will be made up from the grid.
