Florida Power and Light lobbyists made it illegal to use solar during outages

unless you are Mr. Burns and can blot out the Sun, solar panels cannot be turned off. The power they make can be sent to batteries if you have a true off-grid system, backfed to the grid if you have no batteries, or sent to a diversion load. You cannot turn off solar panels. A household air conditioner is a perfectly fine diversion load, for one example, water heater elements are popular.

I may have used the term “panels” rather than inverters a few times to try and make sure someone understood me.
That was a mistake. I also called it “solar”, when the term is “photovoltaic”. I apologize for the technical errors. I will make sure that I clarify these terms when I submit my comments to my IEEE working group.

Also, you don’t need “diversion loads” for PV. We frequently oversize PV panels to get longer maximum output from inverters. In other words, we might put 100kw(max) PV on a 50kva inverter. This insures that you can maintain 50kva for a longer period of time. You do not need to maximize output of the photovoltaic elements.

preventing home power systems from islanding is a solved problem. The system we installed at my kids school and the system we are currently installing in our church use normal, everyday anti-islanding inverters as required by code. They do not “turn off the solar” when the grid is out, because that would require turning off the sun.

Yes. That is called IEEE 1547 compliance.
The photovoltaic panels are not "turned off’. The always exhibit potential. The inverter ceases to produce an output AC current.

Then again, this is a technology that confuses people so much that NEC cannot agree on the definition of a “panel”, so I don’t think you are going to see consistent terminology.
