The other question simply being how much it would cost to take out a swathe of them - which would happen from time to time especially if the mounts are frangible. Hundreds of thousands? I would suspect they need to be quite firmly mounted to deal with strong winds.

There are apparently concerns about dazzling pilots.

Personally I would expect that solar panels "should" not dazzle, as efficient panels should be absorbing the energy rather than reflecting it, but I'm given to understand that it's a real concern.

I guess anything glossy and flat may cast a specular reflection that is likely to be very directional and may well dazzle.

Trees should be black, but aren't.

I am one and would thank you for the compliment:rolleyes:

Good point. And they've had longer to get it right than we have.
