I don't know about a solar farm. But my panels are locked down in so many places that they probably keep the metal roof more secure than without the panels. Not saying it makes them impervious to hurricanes (or in my neck of the woods, tornados). Just saying they probably move the needle some in the good direction.
And by the way, when the grid power goes out I have backup power from my solar panels and batteries. The last time the power went out I was able to operate just fine with some trimmed down use (kinda like running on a backup generator and not having enough power for all the normal luxuries, but I get to choose them without having to run cables around and cranking up a generator). Once the weather clears and the sun comes out, I operate on a full use, even if the grid's still down. That's because on most days my solar system generates more power than I use or can store for the future.
The kiln, what about the kiln?
