But that said, Western Power's inflexible blanket ban on any feed-in above 5kW (single phase) has had a wonderful side benefit of enabling solar companies to be ultra competitive with the 6.6/5 kW system installs because basically everybody wants the same equipment, allowing much greater standardisation.
Electricity is still dirt cheap in WA (30c/kWh) but that will soon change.
Interestingly, solar has penetrated so far in WA that there's almost no value to the grid operator of putting more daytime solar onto the grid.
