> They come with small inverters to convert the DC output of the solar panels into AC power, which plug straight into an existing home power socket.
Hopefully these inverters are smart enough to cut the feed if the AC mains power goes out, to avoid backfeeding utility lines that may be under repair.
There are two types of balcony solar. One is bidirectional power flow, i.e., classical balcony solar, and the other is called "zero export", in which a current flow direction sensor on your mains throttles back your inverter if you start to reverse the current flow and export power.
Where I live, in the US, National Grid is okay with balcony solar as long as it's a zero-export balcony solar. Your power utility may take a similar approach. They might also take a "if it doesn't cross the meter, and we can't tell what you're doing, then we can't tell you not to do it"
The only negative thing I feel about all of this is that we're doing now. Once the glaciers are farked, the snow is going and the mass die offs are started. Better late than never they say, but why the hell didn't we just invest in this in the 1990s?
We did invest, starting in the 1970s, which is what brought the prices down so much. It just took time to get the R&D to the point where they were cost competitive.
The social problem is that fossil fuel usage was very profitable and employed enough people that polluters were allowed not to pay for externalities and a lot of climate change denial funded by the oil companies proved effective at getting politicians and the public to downplay the risk. Even today, even on HN, you can find people who’ll say it’s no big deal, the earth has been this warm in the past, that it’ll cost too much, that they can never drive an EV because their daily commute is 11 hours each way without stopping, etc.
Because fossil fuel lobbyists so successfully captured most right-wing parties, millions of people added that to their self identity and thus will struggle to admit they were wrong because that more or less means admitting that the same people who lied to them about the climate also lied about other things.
I have 2kW of panels on my balcony and 4kWh of batteries. I'm happy with the setup. I expect it to pay for itself in just a few years. The only thing I wish it had is open APIs to control the inverter and the batteries, ideally over bluetooth, so that I'm not forced to use an app.
All to deny the fact that new deal is incompatible with dense cities. Sorry but do the math and you realize that the future is homes and sheds, not condos.

Right now it seems Utah is the only jurisdiction in North America where they are

For both victron and litime plenty of examples exist, including home assistant integrations.
