Twenty four US states are now considering legislation to allow small, plug-in solar power systems that connect directly into a wall socket. (www.nytimes.com)

I'm a little wary of plug-in solar in the US. Some of the bills propose allowing 1200 watt panels which can overload wiring depending on what else is on the circuit and how in the wall wiring is run. Limiting plug-in panel wattage to, say, 400 watts might be necessary

You are vastly overestimating how much power actually gets generated by these panels.

Also, basically every assumption made in the first paragraph is incorrect.

Like I said, I’m weak on the science. I’m more of a computer person.

Most of what I know is based on either a Practical Engineering or Matt Ferrell video, but I’m interested in the topic, if a little too busy to dig deeply enough to get past the marketing. If you have a good info source on the matter, I’d love to check it out.

With that said, the first paragraph is not really applicable to my concern, which is that a grid connected panel + battery could be hacked. En masse, they could dump power onto the grid and fry transformers or take out substations. (Which smarter people than I have identified as a concern, re: EV chargers.)

Hm. Imprecise on my part.
The panels aren’t the concern. It’s stored energy in the battery that can be dumped onto the grid, along with the stored energy of other compromised systems.

The article I linked outlines a scenario like what I’m describing being possible with EV’s that have had their chargers hacked.
