        This article is from the New York Times, a prominent US newspaper which writes primarily for a US audience. It’s relevant for them to bring it up.

        FTA:

        The so-called plug-in systems involve routing the direct current generated by the panels to an inverter, which converts it to an alternating current. They can then be plugged into a conventional wall socket to feed power to a home.

        So, yeah, almost certainly illegal in pretty much any grid-powered home in the US.

        The basic problem is that if the grid power goes down the inverter can back-feed the grid enough to electrocute the people who are working to fix it.

        Utilities require an approved isolation system of some kind that prevents that happening. They are pretty strict about this for various other technical and political reasons too, but evidently it is mostly a safety concern.

        I’ve got some good locations at home for panels, and about 500W in panels that I use for camping, but the equipment I’d need to handle easily and safely consuming the power at home is kind of expensive (just running an inverter and a battery for an isolated system is easy enough, I’ve got all that, but it’s not cheap to seamlessly connect it to my home power system). Would love to have a safe and approved system like what is described in the article.

          Houses in Europe are connected to the grid too.

          These systems are approved in Europe by utilities because they have failsafes implemented to prevent back feeding electricity in the grid.

          The fact that these systems are still illegal in the US is a political issue, not a technical one.

          Balcony solars are not able to back feed since they need the grid to synchronize, if you want one that is able to work in “island mode” you still need approval from the grid provider/one that isnt connected with the schuko connector.

        No, because you can kill a lineman working on the downed line, who mistakenly thinks the line is dead and has no idea that you’re feeding power into it from your solar panel.

          I really feel like one of these store-bought solar panels wouldn’t put out enough electricity to kill someone

            They have enough energy, but they automatically turn off once the grid goes down because they need the grid to synchronize. Balcony solar panels are not able to work in “island mode”, so no lineman is at risk.
