A good reason for using vacuum tubes. Salt doesn't affect the glass

Not like it attacks steel or ali but I bet you'll still get a hefty build
up of salt crystals but then you'll get that on any collector.

One might do, but if the rain doesn't wash them off then all it
takes is a bucket and brush. I don't notice houses by the sea with
salt encrusted roofs, even if the roof has been there for centuries.
