Again, that would increase cost significantly. I didn’t think of this at first because my array doesn’t have RSD because it’s older but all new solar arrays in the US and elsewhere have what’s called rapid shutdown technology for firefighter safety and it is a device that is mounted to each solar panel and does effectively reduce the output to zero or near zero on each solar panel in the event grid power is lost or somebody hits the rapid shutdown emergency button. So the technology is already in place to do what you’re describing but more cost-effective and less elaborate.
Also, something I should have mentioned is that newer inverters like my own, even though they are grid-tied, can be configured to export nothing and only power the home even without a battery. But the problem with this whole line of thinking is that it would screw over homeowners who should be getting money for the solar they put into the grid, but would be getting nothing in these scenarios.
