You can set up a low voltage DC solar setup + battery yourself, but you aren't allowed to do anything that connects to the grid without the proper licenses/certifications.
But I'd say the reason you can't find product licensed to do it is because the amount of savings to be had with some panels hanging of the balcony is pretty minimal, the difficulty of securing them properly so they aren't ripped off in a storm is pretty high, and no owners corp would allow it just for visual reasons alone.
Australia has an absolute abundance of empty land, no trees and sun raining down on it. Makes more sense to invest in these installations and just wire it in to the grid rather than zip tieing panels to your balcony rails.
