Small-scale solar panels about the size of a door are poised to be plugged into more U.S. homes and apartments as homeowners and renters who want to harness the sun’s energy look for cheaper alternatives to rooftop installations.
That’s not what this. This is plugging straight into the wall with a small system. Against code pretty much everywhere. What you’re talking about is only economically viable for large systems that will generate more than the owner can use at peak hours. These small systems are much cheaper, do not require an electrician, and won’t generate enough power to require a net metering setup. The owner will use all of the power it generates even at peak hours. It essentially will just slow their power meter down as they draw less from the grid. These small systems are very common in Europe these days because their regulations have kept up better than ours. Also their outlets in general are safer.
Obviously where this person is that’s legal, so there are exceptions. I assumed this setup involved a battery because they grossly overpaid for a 400 watt system.
If they’re not generating enough to backfeed even at peak, and they can detect when the power cuts off and deactivate until it comes back, is there an actual safety/legal issue?
To plug a solar panel into a wall socket with the intention of adding power to the electrical grid, you need an inverter. Solar panels generate DC, the grid is AC. It is possible to make an inverter that will synchronize to the grid, and if there’s on input waveform, it just won’t put out AC power. “Not grid-forming” is the term I’ve seen used for this.
If you go to harbor freight, buy a gas-powered generator, build a suicide cable and plug it into a socket in your house without throwing your main breaker, you could be energizing lines that a lineman somewhere thinks are not energized, which could injure or kill him.
Worse, by generating your own power you’re reducing the money you have to pay to the power company. That’s punishable by flaying in 14 states.
Mostly a code and legality issue. Local regulations just haven’t caught up in most places. Also there’s no rights for renters for this stuff just about everywhere in the US.
Around here (Maryland) it is totally legal. You just need an interconnect that disconnects the panels from the grid when the grid goes down.
We actually have a system called net-metering, where the utility will buy electricity from residential customers at retail prices.

Okay, that makes more sense, thanks
