Other industry participants, who were not authorised to comment because of their work advising the government, said the scheme had created significant waste.

They pointed out that most households were only using about 10 kilowatt hours of power overnight and would struggle to fill a system with five times as much storage.

what are they talking about...

the average solar system is now 10kw's, I have 6.6kw and can do 35kw in a day, on top of that what happens if you have multiple days of low sunlight? or in winter when you want the sun that does come through to last as long as possible...

you want oversized batteries, they last longer as there's less wear on them and the utility they offer (self-consumption) is increased, on top of this you get an added benefit where you can join a VPP and export your excess unneeded energy at night helping reduce your bills, like with Globird, Flowpower, AGL, Origin battery plans etc

One critic said: "You end up with a lot of batteries that will never fill up, just sitting there empty forever, paid for by the Australian taxpayer."

The average solar system (10kw) can easily fill up a 50kw battery on a sunny day.

Why didn't the ABC take 5 seconds to ask someone with a big battery what their usage is like? Cmon ABC you're better than this
