Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

They generate no frequency so the situation you fear is not possible.

The panels themselves are DC, but there's an inverter feeding 120V 60Hz (or whatever) into the wall, right?

Yes, but it's a system that is designed to sync with the frequency of whatever other electricity is out there, and it shuts of if the main shuts off. Almost all rooftop systems without a battery in the US are set up the same way.

Still, it's important to check that things you think are disconnected do not have current flowing through them. And this makes it more important.

Pure sine wave or modified? Modified (square wave) are not good for electronics, particularly computers.

The answer likely varies by model. Check.
