Aluminum or aluminium?
I don't know, would wear a ring made out of platinium?
There are now More Solar Panels than people in Australia
Asmo says...The technology to load shift is available, but getting it developed and implemented is one of the components that is missing from the overall power strategy in Aus.
Energy companies, like Ergon (Queensland) are actively trying to limit input, with a hard cap of 5kVa input for residential, and sometimes even as little as 3kVa in some more remote areas.
And while technology like liquid vanadium battery cells (long life, expandable by adding extra tanks of liquid electrolyte) exist, they are still prohibitively expensive.
There are plenty of solutions, but little appetite from the companies and governments, and very little knowledge among the end users. So while we're throwing cheap Chinese panels on rooves with gay abandon, I think it's a little early to brag about what a rampaging success Aus solar is because "lots of panels yo!".
Actually, the load shift problem has been solved. You use a dual reservoir small hydro system, pumping water uphill with surplus daytime power and generating it on demand. It takes space, but is relatively inexpensive and is essentially a near maintenance free battery that's as big as your reservoirs and pumps.
