@Anne_Delong@musician.social I did a bit of poking around, and yes it looks like systems on the market have anti-islanding. The other concern was that it would feed back into the grid, but that would only happen if your home was consuming less than the panel was producing, which would require probably more panels than anyone has room for. (For one thing, not all meters can tell which direction power is flowing, so you'd be getting charged for the power you're feeding back to the grid). I also wouldn't want to stuff more than a few hundred watts back into a branch circuit, so you don't want people going nuts with these things.

@SteveWatson@ottawa.place I think in most places where balcony solar has been approved, the regulations limit it to something like 800W for the reason you mention. That's maybe 4 panels. It's not as good as having a proper roof setup where you can sell electricity to the utility when you aren't using it, but still it seems that after several years it pays for itself in lower electrical bills. And since there's no electrical installation, in can be used by renters, and taken with them when they move.
