It isn't, the panel should be powered down as well (but I guess there
isn't enough information how to do it). An undriven panel shows the
effect called 'blooming', and while it's never seemed to damage any of
my panels, I wouldn't count on that.

That won't save power either, but it's probably better than blooming
indeed.
