Hey everyone 
I’m from Albanvale, Victoria, and planning to install a 6.6kW solar system for my 4-bedroom home.
We’re a family of 4, and our average daily power usage is around 20–25 kWh.
I’ve seen that many installers recommend a 6.6kW system as the “sweet spot” for Aussie homes, but I’m wondering — is it actually enough for a typical family household in Albanvale?
Also curious about:
-
How much power (kWh/day) can a 6.6kW system generate in our area?
-
How much can I expect to save on electricity bills?
-
Any brands or installers you’d recommend locally?
Would love to hear your experiences and suggestions before I go ahead with the installation! 
Thanks in advance
