The panels DO remove. That's part of what the pictures we've seen really don't make clear, there's a fantastic amount of engineering here, obviously done from a sailor's point of view. Each solar panel unplugs (one waterproof plug) and then by unscrewing one captive nut (attached with a leash) it folds down flat and attaches to the pole with a rubber strap. So, by unscrewing two captive screws--no tools needed, handles attached to the bolts, not wing nuts--you can drop the panels flat and secure them to the pole. I have no idea what wind strength that would hold against but I'd guess that would secure them up to hurricane forces. After that, all you have to do is loosen that screw completely, then pull one "fastpin" (again attached with a leash) from each panel, and you can remove the panel COMPLETELY and stow it below. Almost as fast as reefing a roller
jib.
The two panels, once removed, attach to each other with four more of the rubber straps, bumpers already on the "glass" so they face each other and keep the glass between them. Pretty well thought out, and a lot of time and money if you tried to build it from scratch.
As to invading Spain...well, you'd have miles more of seacoast, and the eternal gratitude of the Basques. Call it payback for the Spanish Inquisition and the conquest of South and Central America, they're overdue for that.
