Hi,
Looking for advice from an expert !

I looked at my last electricity bill being around $500 for the 1/4.

I also looked into the daily useage:

Std rate - approx 21kw/h per day
Off peak - approx 8 kw/h per day

Question:

Would I need a 4kw system to basically break even on my daily useage and become cost neutral ie: generate enough to meet my daily useage ?

1) What are the best PV panels to use and brand of inverter ?
2) How many panels would I need to generate this ?
3) What would the out of pocket costs be in Sydney for this system ?

Any help appreciated,

TIA

Gav.
