Where are they located? I suspect you may be being lied to.
Electrical companies can't just slap "novel charges" whenever they feel like it. The feed in tariff has dropped to piss-all, sure, but speaking as an aussie with a solar rig, there's a lot of whingeing talk about wanting to "bridge the shortfall" but not much action.
Some states allow to charge for exporting during low demand, but a battery system would usually be hoovering that up anyway. We're talking like $5-$15 a year
You actually see it spread even broader - people thinking they can cheese the hard grind. If i get this equipment i can run longer / ride faster / play better and now we're at the point where people think feeding gibberish into a plageurism machine means they can now Art without effort.
Nope. Stuff can help and it can elevate, sure...but there's gotta be the skill underneath. And you need to work for that.
But i bet reddit atheist comms are going off their shits
