Interesting, but I've been busting my ass covering every inch of my property with real trees, so nowhere to put them.

Also, I kinda like the look of a well installed solar roof array. 

 I cant come to terms with putting holes in a perfectly good tin roof.  

 If you have a standing seam metal roof, they don't put holes in it, they clamp to the seams. 0 perforations that way. 

 I did not know that.
