I'm sure crusted-on salt is great for solar panel efficiency.

I commented on this device on futurology.

Its a great design - It appears they use plastic tubing and connections, which addresses the corrosion issue, and flexible solar panels lying on a large membrane.

The design appears to be cheap and robust and easy to replicate. It could even be cheaper than mounting them on land (no metal stands for example). By floating and cooling the solar panels with sea water, you can get up to 30% efficiency increases (they promise about 10% improvement).

Pairing them with wind turbines is actually a great idea, as they do not have to anchor them to the ocean floor, and of course they can connect easily to power transmission sources.

Rain probably dissolves the salt.

Here is a video showing the construction.

How about layering this on top of some kind of structure that harnesses the tides?

The wave energy generator would have to be a very simple and cheap design, because from what I can see this is a super-simple and cheap design currently.

Actually if they add rigid articulations with generators between each pad in a cluster, they could use the motion of the pads/waves to generate energy, a bit like how these generate energy from the up and down motion of the ocean.

Not sure what you mean by the second paragraph?

If you look at the diagram, each big circle is a pad of solar cells, the green is a rigid linkage between each pad, and the purple circles are generators built into the hinges which generate power due to the relative up and down movement of each pad due to waves.
