RBA Interest Rates to plummet early 2023, page-2262

I get the price info from advertised prices,
And the bill info from our power bill and the average power bill.
As well as also look at the up-coming Increases.

As for the excess power,
That is from friends and relatives Systems.

Interestingly one property is Rural,
Entirely Off-Grid with Solar and Battery,
And never has any problem with power.
Even on cloudy days.

Obviously things like down lights are going to chew more power than conventional LED bulbs,
Not just due to their design,
But as there are usually many more of them per room.
Same as if someone has Air Conditioning, be it ducted or splits Etc.

Solar Hot Water Systems also make a Big Difference,
To how much power a House uses.

Different Invertors can make a big difference,
As well as newer Solar Panels produce more in lower light conditions,
Such as Cloudy Days etc.
Cleaning them also helps.
