During utility power outages, a simple grid-tie solar PV system is required to auto-disconnect from the grid for safety. One cannot utilize power from the PV system while disconnected from the grid (or battery backup), because "the excess current needs somewhere to go." Therefore the panels are disconnected from the inverter as well.
As for a solar panel not connected, the sun's energy falling on it will be converted to heat. This answer might help with the latter. They don't need to send excess power somewhere. Grid tie inverters ARE required to disconnect when the grid fails - but that's principally to avoid killing the guys trying to repair it!
If the grid goes down, the solar goes down automatically. If you have an automatic transfer switch and a compatible battery, the inverters will think the grid is back and turn on by themselves. If you do not have those things, you very much want the solar to stay off. I have a battery so that is not an issue.
The reason I ask is because in the event that there is some disaster or network issue and you are unable to communicate with the software, there has to be some way to manually turn on solar production if it was shut off, the grid is down, and you have battery backup.
I can imagine that if the utility cut the power for maintenance, they would not want power to be fed into the grid. As for a solar panel not connected, the sun's energy falling on it will be converted to heat. This answer might help with the latter. They don't need to send excess power somewhere.
You can turn it off via the breaker. If you have a battery backup, it should be wired such that the battery keeps the solar on, until the battery approaches/reaches full state of charge. You can manually turn on the solar by disconnecting the envoy communication according to the enlighten site.
