I have plans (someday) to add PV panels, but mount them on the ground. I have the yard space and it would be easier to service (clean any leaves off, sweep snow off,etc.) Has anyone given any thought to protecting the panels during storms/tornadoes? I guess I am thinking of being able to collapse the frame so that the panels would be flat on the ground. Any thoughts?

So you are worried about them catching the wind?
If they were mounted on your roof you wouldn't be able, or at least it wouldn't be practical, to lay them flat in a storm. I wouldn't think you would be mounting them any less secure on the ground as you would on a roof.
The same for things flying into them or hail.
However, making them collapsable is easy. We have a set mounted on an RV that fold down against the side when traveling and fold up to create a canopy when parked. Not as effective as a stationary set, I can adjust to some angle but not always the best.
So I think if you wanted to ground mount them the first consideration would be the location and the second the angle. It should be easy enough to lower and raise them.

Yes, worried about them catching the wind. I don't think it is possible to protect them from a direct hit from a tornado. But if expecting straight line winds like from a hurricane passing through, I thought laying them flat and possibly covering with plywood would give some protection.
I guess I would hate to have panels, a storm come through and knock out the power lines and then find out that my PV cells were destroyed also. Bummer.
